Abstract
Listeria monocytogenes is a significant pathogen that causes listeriosis in humans and small ruminants. This study aimed to estimate the prevalence, antimicrobial resistance and risk factors of L. monocytogenes in small dairy ruminants in Jordan. A total of 948 milk samples were collected from 155 sheep and goat flocks across Jordan. L. monocytogenes was isolated from the samples, confirmed and tested for 13 clinically important antimicrobials. Data were also collected on the husbandry practices to identify risk factors for the presence of L. monocytogenes. The results showed that the flock-level prevalence of L. monocytogenes was 20.0% (95% CI; 14.46%-26.99%) and the prevalence in the individual milk samples was 6.43% (95% CI; 4.92%-8.36%). The univariable (UOR=2.65, p = 0.021) and multivariable (AOR=2.49, p = 0.028) analyses showed that using water from municipality pipelines as a water source in the flock reduced L. monocytogenes prevalence. All L. monocytogenes isolates were resistant to at least one antimicrobial. High percentages of the isolates were resistant to ampicillin (83.6%), streptomycin (79.3%), kanamycin (75.0%), quinupristin/dalfopristin (63.8%) and clindamycin (61.2%). About 83.6% of the isolates (94.2% and 75% of the sheep and goat isolates) exhibited multidrug resistance (resistance to ≥3 antimicrobial classes). In addition, the isolates exhibited fifty unique antimicrobial resistance profiles. Thus, it's recommended to restrict the misuse of clinically important antimicrobials and to chlorinate and monitor the water sources in sheep and goat flocks.

Abstract
Limited data is available on the prevalence and antimicrobial resistance of extended spectrum (ESBL) and AmpC β-lactamases Escherichia coli in sheep and goats in Jordan. This study determined the molecular prevalence and antimicrobial-resistance of ESBL and AmpC β-lactamases E. coli in 155 sheep and goat flocks across Jordan by testing 948 milk samples. The samples were enriched in MacConkey broth, and then plated on MacConkey agar with cefotaxime. The presence of ESBL and AmpC genes in the E. coli isolates was determined by PCR and the resistance toward critically important antimicrobials was tested by disc diffusion. In total, 1016 E. coli isolates were isolated from the cefotaxime supplemented MacConkey, 382 isolates harbored ESBL genes and 54 harbored blaCMY. The prevalence of blaCTX-M, blaTEM, blaCMY and blaSHVE. coli in the milk samples were 33.5 %, 31.7 %, 5.7 %. and 1.1 %, respectively. At the flock level, 30.3 % flocks had β-lactamase E. coli, specifically 25.2 %, 20.7 %, 5.2 % and 2.6 % had blaCTX-M, blaTEM, blaCMY and blaSHV E. coli, respectively. About 52.2 % of the isolates harbored both blaCTX-M and blaTEM. A high percentage (>59 %) of ESBL and AmpC β-lactamases E. coli resisted sulfamethoxazole/trimethoprim, tetracycline and nalidixic acid. Overall, 93.5 % and 96.3 % of ESBL and AmpC E. coli were resistant to ≥1 another antimicrobial class and 44.5 % and 44.4 % were resistant to ≥3 another antimicrobial class, respectively. This study shows that sheep and goat milk is a reservoir of multidrug resistant ESBL and AmpC β-lactamases E. coli, thus good hygienic practices and judicious antimicrobials use are important in small ruminants' farming.

Abstract
Brucellosis is a significant zoonotic disease and is endemic in several regions of the world. This study is aimed to determine the nationwide spatial distribution, seroprevalence, and risk factors for Brucella infections in Jordan. Serum samples of 938 individuals from 11 governorates were tested for Brucella spp. antibodies using Rose Bengal and Brucellacapt® tests. A validated questionnaire was used to collect demographic, animal ownership, and food consumption data. The seroprevalence of Brucella infection in Jordan’s population was 6.7% (95% CI, 5.2–8.5%). The multivariate model showed that location of residence, consuming raw milk/milk products, and owning small ruminants (goat and/or sheep) were significantly associated with seropositivity after controlling for age and gender. Individuals living in the northern Badia region had 8.82 greater odds (95% CI, 4.56–17.03) of seropositivity than individuals living in the Middle region of the country. Individuals who reported consumption of raw milk/milk products had 3.7 higher odds (95% CI, 2.01–6. 81) of seropositivity compared with individuals not consuming raw milk/milk products. In addition, individuals who own small ruminants (goat and/or sheep) had 2.14 higher odds (95% CI, 1.11–4.12) of seropositivity compared with individuals who do not own small ruminants. The identified geographic hotspots and small ruminants’ ownership, risk of raw milk products highlight the need for tailored training, education campaigns, and resources for controlling brucellosis in Jordan.

Abstract
Extended-spectrum β-lactamase Escherichia coli is an important cause of urinary tract infections in humans. ESBL producers E. coli were reported in food-producing animals, but no previous study reported the virulence potential of these isolates. Thus, this study determined the virulence potential of ESBL producers E. coli isolates from 518 beef feces, 610 dairy cow feces, 305 dairy cow milk, 503 sheep milk and 445 goat milk samples. A total of 278 isolates; specifically, 130 from beef feces, 39 from the cow's feces, 42 from cow's milk, 44 from sheep milk and 23 from goats' milk were isolated and then tested for 14 virulence genes by polymerase chain reaction. After that, the correlation of virulence genes presence among the isolates was determined statistically. Overall, 97% of the isolates carried fimH, 39% carried iroN E. coli and 32% carried papC. The kpsMT K1, cnf1, papAH, papG allele II & III, papG allele II, and kpsMT II were carried by 6 to 23% of the isolates, while less than 6% of the isolates carried papG allele III, papG allele I, Univcnf, iutA and hlyA. About 68.2% of the isolates carried two or more virulence genes and 41.8% carried three or more. Moreover, the isolates had 71 different profiles of virulence genes, where the most common profiles were fimH alone (86 isolate), fimH + iroN E. coli (35 isolate), fimH + papC (20 isolate), and fimH + papC + iroN E. coli (13 isolate). The adhesion, capsule synthesis and toxins secretion genes were significantly associated (p ˂ 0.01) with each other. These results call for awareness about the risk of food animals as reservoirs of ESBL uropathogenic E. coli that would threaten public health and limits the treatment options for urinary tract infections.

Abstract
BACKGROUND Leptospirosis is re-emerging as a major public health problem worldwide. However, there are limited data on the disease from the Middle East, including from Jordan, despite recent outbreaks occurring in Jordan's neighbouring countries. METHODS Sera samples from 809 participants in 11 governorates were tested for Leptospira sp. seropositivity to determine the seroprevalence and risk factors of Leptospira sp. in Jordan. RESULTS Overall, 3.3% (95% confidence interval [CI] 2.2 to 4.8) of individuals tested were seropositive for Leptospira antibodies. Individuals who drink surface water (spring or rain water) had 5.69 (95% CI 2.57 to 12.60) higher odds of seropositivity compared with individuals who used municipal or filtered water, after controlling for age and practicing horticulture. CONCLUSIONS This is the first seroprevalence study of Leptospira sp. in Jordan and included important data on environmental and animal exposures.

Abstract
Lyme borreliosis has not been studied in Jordan or in much of the Middle East. However, limited research indicates that the tick vector, Ixodes ricinus, exists in the region. This study examined the seroprevalence of B. burgdorferi s.l. in Jordan and potential demographic and zoonotic risk factors for seropositivity. Serum samples of 824 apparently healthy participants from 11 governorates in Jordan were tested for B. burgdorferi s.l. using Enzygnost Lyme link VlsE/IgG enzyme-linked immunosorbent assay. A validated questionnaire was used to collect demographic and animal exposure data. Univariate and multivariate logistic regression were used to identify factors associated with seropositivity. The results showed that 11.7 % (95 % CI, 9.3-14.0 %) of the participants were seropositive for B. burgdorferi s.l.. There was a bimodal age distribution of seroprevalence with higher seroprevalence among individuals <20 and>60 years old. After controlling for governorate of residence, females had 2.77 (95 % CI 1.53-5.00) times greater odds of seropositivity compared to males. Individuals living in the southeastern part of Jordan (Ma'an) had 2.32 (95 % CI, 1.02-5.31) greater odds of seropositivity compared to those living in Amman, the Capital of Jordan, while those living in the northeast had significantly lower odds of seropositivity. This study presents the first evidence of B. burgdorferi s.l. seropositivity in Jordan and suggests several risk factors which were reported in studies conducted elsewhere. This study suggests that Lyme borreliosis should be considered in the differential diagnosis for patients presenting with skin lesions in Jordan.

Abstract
There is a paucity of data on Francisella tularensis in the Middle East and North Africa. This is the first countrywide study to determine the seroprevalence, spatial distribution, and risk factors for F. tularensis in Jordan. A total of 828 Jordanians were serologically tested for F. tularensis by ELISA. These individuals filled out a self-administered questionnaire to collect demographic and risk factor information. Bivariate and multivariate logistic regressions were performed to determine which variables are associated with seropositivity. The overall seroprevalence of F. tularensis was 7.7% (95% CI: 6.10-9.75). The bivariate analyses showed that age, region of residence, small ruminant ownership, and practicing horticulture were significantly associated with seropositivity, and these variables were controlled for in the multivariate analysis. The multivariate analysis showed an increased odds of seropositivity among individuals living in northern desert, middle, and northern highland areas, compared with individuals living in the drier southern area, as 7.27 (95% CI: 2.49-21.19), 3.79 (95% CI: 1.53-9.39), and 3.52 (95% CI: 1.45-388.55), respectively. Individuals owning a small ruminant had 1.86 (95% CI: 1.02-3.40) greater odds for seropositivity than individuals who do not own a small ruminant. Individuals practicing horticulture had 2.10 (95% CI: 1.20-3.66) greater odds for seropositivity than individuals who do not practice horticulture. This is the first study to address the seroprevalence of F. tularensis in Jordan and the Middle East. Further research is needed to identify clinical cases of tularemia in Jordan and to determine the circulating F. tularensis subspecies.

Abstract
OBJECTIVES Hepatitis E virus (HEV) is zoonotic and endemic in several countries. There are no data on the farm level-prevalence and risk factors of HEV in ruminant farms in Jordan or elsewhere. This study aimed to estimate the seroprevalence and risk factors of HEV in ruminant farms in all regions of Jordan. MATERIAL AND METHODS A total of 460 apparently healthy ruminants from 115 (31 cow, 51 sheep and 33 goat) farms were tested for HEV antibodies using a double antigen sandwich enzyme linked immunosorbent test. A validated questionnaire was used to collect data on animal health and husbandry practices. RESULTS The results showed that 37.4% of the dairy farms under study (51.6%, 37.2% and 24.2% of dairy cow, sheep and goat farms; respectively) had at least one HEV seropositive animal. At the individual animal level, 12.1% of the tested animals were HEV positive; 14.5% (n = 18), 12.7% (n = 26) and 8.3% (n = 11) of cows, sheep and goats; respectively. Infrequent cleaning of feeders was associated with a significantly greater odds of HEV seropositivity in both large and small dairy ruminant farms (AOR = 16.0, p-val = 0.03, AOR = 3.4, p-val = 0.02, respectively). Farms which reported that small ruminants (sheep and goats) were mixed together had a greater odds of farm-level HEV seroprevalence (AOR = 3.1, p-val = 0.04). CONCLUSIONS This study shows widespread and high farm-level HEV seroprevalence in dairy farms in Jordan. Husbandry practices and off-abattoir carcass processing in Jordan could amplify emergence and transmission of zoonotic HEV. Future studies should include HEV genotyping in ruminants, their products and humans to better understand HEV epidemiology in Jordan.

Abstract
This study characterized Listeria monocytogenes, Salmonella enterica, and E. coli O157:H7 by collecting rectoanal mucosal swabs and fecal samples from 518 imported beef cattle at Jordan's major abattoir. A unique 53 L. monocytogenes, 287 S. enterica, and 17 E. coli O157:H7 were isolated from 37, 120 and 9 different animals; respectively. The prevalence of S. enterica, L. monocytogenes and E. coli O157:H7 were 23.2 % (95 % CI, 19.7-27.0 %), 7.1 % (95 % CI, 5.2-9.7 %) and 1.7 % (95 % CI, 0.9-3.3 %); respectively. All L. monocytogenes, all E. coli O157:H7 and 93.0 % of S. enterica isolates resisted at least one antimicrobial class. All L. monocytogenes, 94.1 % of E. coli O157:H7 and 69.7 % of S. enterica isolates exhibited multidrug resistance (resistant to ≥3 antimicrobials classes). Moreover, high percentages of L. monocytogenes (98.1 %), E. coli O157:H7 (64.7 %) and S. enterica (45.3 %) isolates resisted ≥5 antimicrobial classes. More than 90 % of the L. monocytogenes isolates resisted ampicillin, penicillin and erythromycin and more than 75 % resisted vancomycin. S. enterica isolates resisted several treatment-of-choice antimicrobials such as nalidixic acid (85.4 %), ciprofloxacin (26.8 %) and ceftriaxone (19.5 %). Furthermore, greater than 50 % of the E. coli O157:H7 isolates resisted streptomycin, nalidixic acid, tetracycline, ampicillin, sulfamethoxazole-trimethoprim, kanamycin, chloramphenicol and ciprofloxacin. The high prevalence and the high resistance percentages of the studied pathogens toward clinically important antimicrobials is alarming. Thus, applying strict sanitation procedures at the abattoirs in Jordan is crucial to lower the risk of carcasses contamination.

A total of 781 individuals from 11 governorates of Jordan were tested by SERION ELISA classic C. burnetii IgG Phase 2. A validated and pretested questionnaire was used to collect risk factors and demographic data. The overall seroprevalence for C. burnetii was 24.2% (95% CI; 21.3-27.3%). Unadjusted odds ratios showed that governorate of residence, consumption of raw milk, and ownership of sheep, goats, and dogs were significantly (P ≤ 0.05) associated with C. burnetii seropositivity. The multivariate logistic regression showed that individuals who own small ruminants had three times greater odds of seropositivity than those who do not own a small ruminant, after controlling for age, gender, raw milk consumption, and ownership of dogs. In addition, individuals who live in Al-Karak, Az-Zarqa, and Al-Tafilah had significantly greater odds of seropositivity compared with individuals who live in the capital city, Amman (OR = 3.6, 4.8, and 2.7, respectively). This study suggests that preventive measures should be practiced in ruminant farms in Jordan to avoid C. burnetii infection. Coxiella burnetii should also be considered in the differential diagnosis of febrile-like illnesses in Jordan, especially among farmers and veterinarians.

Abstract
Background This is the first countrywide study of the seroprevalence, risk factors and spatial distribution of West Nile virus (WNV) in Jordan. Methods A cross-sectional sample of 801 participants was administered a comprehensive questionnaire survey and tested for WNV immunoglobulin G antibodies. Results The point seroprevalence rate for WNV infection was 8.61% (95% confidence interval 6.8 to 10.8). Multivariate regression analysis demonstrated that sex, age, climate, income and drinking water source were significantly associated with seropositivity (p≤0.05). Males had 1.73 greater odds of infection compared with females. Compared with 15 to 29-year-olds, adults 30-49 y old and adults ≥50 y old had 2.0 and 3.1 greater odds of infection, respectively. Individuals living in the Jordan Valley and Badia had 22.2 and 7.2 times greater odds of infection, respectively, compared with individuals living in the highlands. Households with an income of <US$750/month had 1.8 greater odds of infection compared with those with higher household incomes. Individuals using spring lakes as a drinking water source had 5.1 greater odds of infection than people who used water from any other source. Conclusions This study demonstrates that WNV is circulating in Jordan and should be considered as a differential diagnosis in medical cases presenting with nervous system symptoms, especially for older populations living in the Jordan Valley and Badia areas.

Abstract
Background There are no data available on dengue epidemiology in Jordan. This is the first study of the seroprevalence and risk factors of dengue virus (DENV) infection in Jordan. Methods Sera samples from 892 apparently healthy individuals from all over Jordan were tested for DENV by enzyme-linked immunosorbent assay and a validated questionnaire was completed by all participants to identify and rank possible risk factors. Results The seroprevalence was 24.6% (95% confidence interval 21.8 to 27.5). In univariate regression analysis, age, education, history of travel, living in rainy areas and practicing agriculture were significantly (p<0.05) associated with seropositivity. The multivariate logistic regression model showed that those who live in a rainy climate (odd ratio [OR] 1.7), are older (OR 2.3), have a history of international travel (OR 1.5) and are male with a history of international travel had a significantly greater odds of DENV seropositivity (OR 3.4). Conclusions These data suggest that DENV circulates in Jordan and that cases may be imported or locally transmitted. Further research is needed to determine the circulating DENV serotypes and vectors in Jordan. Given the high rate of DENV seropositivity, dengue should be considered as a differential diagnosis in febrile diseases in Jordan, especially among populations living in rainy climates.

Abstract
This study determined the prevalence, pulsed-field gel electrophoresis profiles, and antimicrobial resistance profile of Listeria monocytogenes, Salmonella enterica, and Escherichia coli O157:H7 isolates from dairy cattle farms in Jordan. Samples from bulk tank milk (n = 305), cattle feces (n = 610), and rectoanal mucosal swabs (n = 610) were collected from 61 dairy cattle farms. We confirmed 32 L. monocytogenes, 28 S. enterica, and 24 E. coli O157:H7 isolates from the samples. The farm-level prevalence (at least 1 positive sample per farm) of L. monocytogenes, S. enterica, and E. coli O157:H7 was 27.9, 19.7, and 23.0%, respectively. The prevalence of L. monocytogenes, S. enterica, and E. coli O157:H7 in bulk tank milk was 7.5, 1.6, and 3.3%, respectively. The prevalence of L. monocytogenes and S. enterica in fecal samples was 1.5 and 3.8%, respectively, and the prevalence of E. coli O157:H7 in rectoanal mucosal swabs was 2.3%. Based on disk diffusion testing, all L. monocytogenes, S. enterica, and E. coli O157:H7 isolates exhibited resistance to at least 1 antimicrobial class. Multidrug resistance (resistance to 3 or more classes of antimicrobials) was exhibited by 96.9% of L. monocytogenes, 91.7% of E. coli O157:H7, and 82.1% of S. enterica isolates. Moreover, 93.8, 79.2, and 57.1% of the L. monocytogenes, E. coli O157:H7, and S. enterica isolates, respectively, were resistant to 5 or more antimicrobial classes. More than 50% of L. monocytogenes isolates were resistant to ampicillin, clindamycin, penicillin, erythromycin, quinupristin-dalfopristin, streptomycin, teicoplanin, linezolid, vancomycin, kanamycin, and tetracycline. More than 50% of S. enterica and E. coli O157:H7 isolates were resistant to ampicillin, cephalothin, nalidixic acid, kanamycin, streptomycin, amoxicillin-clavulanic acid, and tetracycline. The prevalence of the studied pathogens this study was comparable to reports from other countries. The isolated pathogens exhibited a high degree of antimicrobial resistance, suggesting that the bacterial flora of dairy cattle in Jordan are under intense antimicrobial selection pressure. Additional research is required to determine the causes and drivers of resistance, and to develop approaches to mitigating antimicrobial resistance.

Abstract
BACKGROUND AND AIM Helicobacter pylori inhabits the gastric mucosa of humans and causes 89% of all gastric cancers. This is the first study of the seroprevalence, spatial distribution, and risk factors for H pylori in Jordan. MATERIALS AND METHODS This is a cross-sectional study of 460 healthy participants (aged between 15 and 81 years) proportionately sampled across each region of Jordan. Sera samples were tested for H pylori using Enzygnost® anti-H pylori immunoglobulin G enzyme-linked immunosorbent assay. Participants completed a validated questionnaire about potential risk factors including food consumption habits and environmental and animal exposure. Multivariate generalized linear models identified risk factors for infection. RESULTS The results showed a high seroprevalence (88.6%; 95% confidence interval [CI]: 85.3-91.2) of H pylori in the study population. After adjusting for possible confounders, age, consumption of raw milk, and location of residence were significantly associated with seropositivity. Older participants aged 30-49 years had an 11% greater risk of seropositivity compared to participants aged 15-29 years. Participants who consume raw milk and dairy products have a 9% decreased risk in seropositivity (prevalence ratio = 0.92; 95% CI: 0.84-0.99) compared to those who do not consume these products. CONCLUSION This study reports a negative association between consumption of raw milk and seropositivity, and this is in line with several studies that report consumption of raw milk may be protective against H pylori. However, because of the risk of other serious pathogens associated with the consumption of raw dairy products, this study recommends pasteurization of raw milk. Future studies on the effect of fermented dairy products on H pylori colorization in gastric mucosa are recommended.

Abstract
We estimated the seroprevalence of, and associated risk factors for, anaplasmosis in dairy cows, sheep, and goats in all regions of Jordan. Apparently healthy animals from 135 farms (31 cow, 68 sheep, and 36 goat farms) were tested for Anaplasma spp. antibodies by a competitive ELISA. At the farm level, 36%, 94%, and 94% of cow, sheep, and goat farms, respectively, were seropositive for Anaplasma spp. At the individual animal level, 22%, 89%, and 82% of the tested cows, sheep, and goats, respectively, were seropositive, which demonstrates widespread and high seroprevalence of Anaplasma spp. in dairy farms in Jordan. Seroprevalence did not vary between regions. Using the Fisher exact test, there was a significant association between high seroprevalence and recent abortion in small ruminants. There is an urgent need for further investigation of this disease, and the potential role of Anaplasma spp. in abortions, on dairy farms in Jordan.

Abstract
Dogs can carry and share zoonotic pathogens with humans. This problem is understudied in different parts of the world, including Jordan. This study determined the prevalence of Anaplasma phagocytophilum, Ehrlichia canis, Dirofilaria immitis, and Borrelia burgdorferi using the SNAP 4Dx Plus test and spotted fever group rickettsiae (SFGR) using enzyme immunoassay IgG test in different types of dogs (farm/breeding, police, and stray) in Jordan. The results showed a very high seroprevalence (87%) of SFGR in dogs all over Jordan. Specifically, the seroprevalence was 97.0, 90.5 and 71.2% in farm, stray, and police dogs, respectively. Overall, 9.9% of dogs were seropositive for A. phagocytophilum. Specifically, 14.9% of farm, 14.3% of stray, and 0% of police dogs were seropositive. None of the studied dogs had D. immitis, E. canis, or B. burgdorferi. It can be concluded that SFGR and A. phagocytophilum are endemic in Jordan. This study suggests that controlling stray dogs and monitoring dog breeding farms should be considered as control measures to limit the transmission of SFGR and A. phagocytophilum and to limit their public health impact in Jordan. Moreover, further follow-up studies are needed to study these pathogens in the human population in Jordan.

Abstract
Vibrio parahaemolyticus is a leading cause of seafood-associated illness. This study investigated the prevalence, virulence, and antibiotic resistance of V. parahaemolyticus in three low- and middle-income countries. Freshly caught fish samples (n = 330) imported to Jordan from Yemen, India, and Egypt were tested. The overall prevalence of V. parahaemolyticus was 15% (95% confidence interval: 11 to 19%). Three isolates (6%) were positive for the thermostable direct hemolysin-related (trh) gene, and all isolates was negative for the thermostable direct hemolysin (tdh) gene. All isolates were resistant to colistin sulfate, neomycin, and kanamycin, and 51 and 43% of isolates were resistant to tetracycline and ampicillin, respectively. Only 4% of the isolates were resistant to cefotaxime and chloramphenicol, and no isolates were resistant to sulfamethoxazole-trimethoprim, streptomycin, gentamicin, ciprofloxacin, and nalidixic acid. All isolates were resistant to two classes of antibiotics, and 86% were multidrug resistant (resistant to at least one drug in three or more classes of antibiotics). A literature review of clinical, seafood, and environmental V. parahaemolyticus isolates worldwide revealed high rates of gentamicin and ampicillin resistance, emerging resistance to third-generation cephalosporins, and limited resistance to sulfamethoxazole-trimethoprim, ciprofloxacin, nalidixic acid, and chloramphenicol. Thus, last-resort antibiotics could be ineffective for treating V. parahaemolyticus infections. Several global reports also documented illness outbreaks in humans caused by trh- and tdh-negative V. parahaemolyticus strains. More research is needed to determine whether the presence of these genes is sufficient to classify the strains as virulent.

Abstract
This large-scale cross-sectional study was conducted to determine the prevalence, geographical distribution, and risk factors for the presence of antibodies against Coxiella burnetii in bulk tank milk derived from dairy cattle, sheep, and goats in Jordan. Bulk milk samples were collected from 78 dairy cattle, 48 sheep, and 23 goat farms from various places in Jordan according to the density of these animal species in each region of the country. The samples were tested for C. burnetii antibodies using the CHEKIT Q-Fever Antibody ELISA kit. A standardized questionnaire was also used to collect data from each farm to identify and rank the risk factors for the presence of C. burnetii antibodies. The results revealed that 62.9% (95% confidence interval: 55.1 to 70.0%) of the tested ruminant farms were positive for C. burnetii antibodies. Positive results were obtained from 70.9% (60.6 to 79.5%) of dairy cattle farms, 52.1% (38.3 to 65.5%) of sheep farms, and 56.0% (37.1 to 73.3%) of goat farms. Six factors were associated with the presence of these antibodies on cattle farms, and five factors were associated with these antibodies on sheep and goat farms (chi-square test). The multivariate logistic regression model revealed that large dairy cattle farms, farms that add new animals to the herd, farms that infrequently clean the feeders, and farms in particular areas are 28.6, 19.9, 8.0, and 6.4 times more likely, respectively, to have animals with C. burnetii antibodies. Sheep and goat farms that mix their animals with those from other farms, graze more than 5 km, and infrequently sanitize the feeders were 8.0, 0.06, and 13.6 times more likely, respectively, to have animals with C. burnetii antibodies. These data reveal the widespread exposure of Jordanian ruminants to C. burnetii and suggest a high risk for public health.

Abstract
This study determined the prevalence and antimicrobial resistance of human-specific ( Shigella spp.) and zoonotic ( Salmonella enterica ) foodborne pathogens in internationally traded seafood. Sixty-four Salmonella and 61 Shigella isolates were obtained from 330 imported fresh fish samples from Egypt, Yemen, and India. The pathogens were isolated on selective media, confirmed by PCR, and tested for antimicrobial resistance. Approximately 79 and 98% of the Salmonella and Shigella isolates, respectively, exhibited resistance to at least one antimicrobial, and 8 and 49% exhibited multidrug resistance (resistance to three or more antimicrobial classes). Generally, Salmonella exhibited high resistance to amoxicillin-clavulanic acid, cephalothin, streptomycin, and ampicillin; very low resistance to kanamycin, tetracycline, gentamicin, chloramphenicol, nalidixic acid, sulfamethoxazole-trimethoprim, and ciprofloxacin; and no resistance to ceftriaxone. Meanwhile, Shigella spp. exhibited high resistance to tetracycline, amoxicillin-clavulanic acid, cephalothin, streptomycin, and ampicillin; low resistance to kanamycin, nalidixic acid, sulfamethoxazole-trimethoprim, and ceftriaxone; and very low resistance to gentamicin and ciprofloxacin. Salmonella isolates exhibited 14 resistance profiles, Shigella isolates 42. This study is novel in showing that a human-specific pathogen has higher antimicrobial resistance percentages and more diverse profiles than a zoonotic pathogen. Thus, the impact of antimicrobial use in humans is as significant as, if not more significant than, it is in animals in spreading antibiotic resistance through food. This study also demonstrates that locally derived antimicrobial resistance can spread and pose a public health risk worldwide through seafood trade and that high resistance would make a possible outbreak difficult to control. So, capacity building and monitoring harvest water areas are encouraged in fish producing countries.

Abstract
Campylobacter jejuni is an important pathogen of significant public health importance. This pathogen is associated with human infection and has been isolated from mammals and birds. Ninety-two cloacal C. jejuni isolates were identified from 35 layer farms in Northern Jordan. Antimicrobial susceptibility was determined using minimal inhibitory concentration (MIC) and disc diffusion techniques with variable suggested breakpoints. Using MIC and EUCAST cut-off values, the study revealed a significantly high resistance level (100%) among the layers' isolates against ciprofloxacin and tetracycline. A relatively high resistance (41%) toward gentamicin and amoxicillin and low resistance to nalidixic acid (21%), erythromycin (14%), and florfenicol (6.5%) were also found. This high level of resistance may indicate abuses in the handling of antibiotics, which may require stricter control in the local layer industry. A good agreement between the 2 techniques used was demonstrated and the disc diffusion technique could be used as a rapid screening test for antimicrobial susceptibility of C. jejuni to many antibiotics using specific Campylobacter breakpoints.

Abstract
A total of 156 Staphylococcus aureus isolates were obtained from 330 imported fresh fish samples from three countries. Selective media were used for the isolation of S. aureus, and the isolates were confirmed by PCR. The isolates were tested for mecA gene, antibiotic resistance, and enterotoxin genes (sea, seb, sec, sed, see, seg, seh, and sei). Most isolates carried sea, seg, and sei genes, and seg-sei was the most frequent enterotoxin profile. About 88.5% of the S. aureus exhibited resistance to at least one antibiotic. High resistance to penicillin and ampicillin; low resistance to tetracycline, erythromycin, rifampin, and clindamycin; and very low resistance to cefotaxime, amoxicillin-clavulanic acid, gentamicin, and ciprofloxacin were exhibited by S. aureus from the three countries. In addition, some antibiotic resistance exhibited a strong correlation (P ≤ 0.01) with enterotoxigenicity in S. aureus. The study concluded that the large amount of globally traded fish increases the possibility of intercontinental transmission of enterotoxigenic and multidrug-resistant S. aureus through fish and highlights the potential influence of local fish handling and processing on consumer health worldwide. The introduction of periodic training in food safety and hygiene is essential to increase fish handlers' awareness of good hygienic practices in handling fish. These findings also enrich the ongoing debate about the risk of methicillin- and multidrug-resistant S. aureus as a foodborne pathogen compared with drug-susceptible S. aureus.

Abstract
Foodborne toxoplasmosis is a leading cause of foodborne deaths and hospitalization worldwide. The level of exposure to Toxoplasma gondii is influenced by culture and eating habits. There is a scarcity of data about women's knowledge and perception of this disease. The aim of this study was to determine toxoplasmosis knowledge and preventive practices of young childbearing age women in Jordan. A descriptive cross-sectional study recruited a random sample of 1,390 undergraduate university female students and was stratified based on place of residency. About half of students (51.1%) reported having "ever" heard or read about toxoplasmosis, and almost all students (98.6%) had never been tested for toxoplasmosis. Overall, there was a lack of awareness about toxoplasmosis, its risk factors, symptoms, and timing of infection, and preventive practices. High percentages of females reported a high level of hygienic practices related to hand washing after gardening, changing cat litter, and handling raw meat. However, 16.7% of students reported eating raw meat, 26.5% usually eat traditional herbs, and 17.2% drink untreated spring water. This study establishes a baseline for the awareness levels about toxoplasmosis among young women in Jordan. These findings highlight the urgent need for toxoplasmosis awareness and preventive education for childbearing females. An effective education and outreach program should cover important topics concerning risk factors, high-risk foods, and preventive measures against toxoplasmosis.

Abstract
A total of 104 Listeria monocytogenes isolates from 330 fish samples from three countries were characterized by multiplex PCR for serogrouping and virulence markers determination and tested for antibiotics resistance. A 53·8% of the isolates belonged to serogroup 1/2a, 3a; 32% belonged to 1/2b, 3b, 7; 14·4% belonged to 4b, 4d, 4e and 1% belonged to 1/2c, 3c. All isolates exhibited resistance to at least one antibiotic but the resistance rates varied among countries. The isolates exhibited high resistance to penicillin, rifampicin, clindamycin, erythromycin and tetracycline, but low resistance to amoxicillin-clavulanic acid, streptomycin, sulfamethoxazole-trimethoprim, gentamicin, chloramphenicol and kanamycin. When comparing countries, the resistance rate for rifampicin, clindamycin, erythromycin, tetracycline, amoxicillin-clavulanic acid varied among countries. When comparing serogroup, 1/2a, 3a exhibited the highest resistance to clindamycin, erythromycin, tetracycline and vancomycin while serogroup 4b, 4d, 4e exhibited the highest resistance to amoxicillin-clavulanic acid. All isolates carried inlA, inlC, inlJ and lmo2672. Listeriolysin S was carried by 42 and 30% of 4b and 1/2b isolates respectively. Significance and impact of the study: This is one of few studies to correlate antibiotic resistance with Listeria monocytogenes serogroups. The study also compared the antibiotic resistance and serogroups of L. monocytogenes isolates from three countries in one single study. The findings of this study will be helpful in improving data on the antibiotics resistance of L. monocytogenes in developing countries and enriches the epidemiological and public health studies of L. monocytogenes.

Abstract
This study determined the levels of As, Cu, Pb, and Cd in fish from Red Sea, Arabian Sea, and Indian Ocean by graphite furnace atomic absorption spectrophotometry. Metal levels were compared with international standards. The levels among fish types and origin, the relationship among metals, and the correlation between the levels and fish size were statistically tested. Fish type and origin significantly affected the levels. None of the fish contained As, Cu, and Pb above the FAO and EU codes. However, Cd exceeded the Jordanian, FAO, and EC codes from the three origins. As and Cd positively correlated with each other in Arabian Sea fish. As and Pb correlated negatively, but Cu and Cd did not correlate with fish size. This study indicates that Cd is common in fish from the three origins regardless the fish size. This warrants continuous monitoring for heavy metals, especially Cd, in internationally traded fish.

Abstract
Antimicrobials in the vapor phase might be more effective in inactivating Escherichia coli O157:H7 cells attached to leafy greens than aqueous antimicrobials. We determined the activity of allyl isothiocyanate (AIT), cinnamaldehyde, and carvacrol against E. coli O157:H7 on intact and damaged lettuce and spinach tissue. Samples were treated with various concentrations of antimicrobial in the vapor phase at 0, 4, and 10 degrees C in an enclosed container. On intact lettuce surface, the vapor of the lowest concentration of these antimicrobials inactivated >4 log of E. coli O157:H7 at 0 and 4 degrees C in 4 days and at 10 degrees C in 2 days. However, at the tissue damaged by cutting, the highest concentration reduced the population by 4 log at 0 degrees C and 2 to 4 log at 4 degrees C in 4 days. These concentrations also reduced the population of the pathogen by 1 to 3 log at 10 degrees C in 2 days. The pathogen population on spinach surface was reduced by 1 log less than on lettuce surface. However, reduction of the pathogen within spinach tissue was 2 and 3 log less than within lettuce tissue at 0 and 4 degrees C, respectively. Overall, greater inactivation occurred on lettuce than spinach leaves and on the leaf surfaces than at the damaged area. Using antimicrobials in the vapor phase may improve the safety of refrigerated leafy greens marketed in sealed packages.

Abstract
Little is known about the effectiveness of antimicrobials in the vapor phase for control of pathogens on the surface of fresh produce. We determined the activity of allyl isothiocyanate (AIT), cinnamaldehyde, and carvacrol against Salmonella and Escherichia coli O157:H7 on sliced and whole tomatoes. Samples were treated with various concentrations of antimicrobial in the vapor phase at 4, 10, and 25 degrees C in a closed container. AIT exhibited the highest antimicrobial activity followed by cinnamaldehyde. The lowest level of AIT (8.3 microl/liter of air) inactivated Salmonella on sliced tomatoes by 1.0 and 3.5 log at 4 and 10 degrees C, respectively, in 10 days and by 2.8 log at 25 degrees C in 10 h. This level of AIT inactivated Salmonella on whole tomatoes to the detection limit of <2 log CFU per tomato at 4 and 10 degrees C in 10 days and by 1.3 log CFU per tomato at 25 degrees C in 10 h. AIT also inactivated E. coli O157:H7 on sliced tomatoes by 3.0 log at 4 and 10 degrees C in 10 days, but there was no inactivation at 25 degrees C in 10 h. AIT reduced E. coli O157:H7 on whole tomatoes surface by 3.0 and 1.0 log CFU per tomato at 4 and 10 degrees C, respectively, in 10 days and by 2.0 log CFU per tomato at 25 degrees C in 10 h. Overall, greater inactivation occurred at 10 than at 4 degrees C and on the tomato surface than between slices. Antimicrobials in vapor phase may be useful for controlling pathogens on fresh tomatoes marketed in packages containing enclosed headspace.
