Abstract
Nitrite and nitrate salts are widely used as curing agents to preserve meat and meat
products. Despite the benefits of using these salts in meat processing, it has some adverse
health effects. The high concentration of these salts produces nitric oxide through various
metabolic reactions followed by the generation of carcinogenic nitrosamines. In this study,
a chromatographic method was developed for the simultaneous determination of nitrite
and nitrate level in meat and meat products. Samples were collected from four different
locations in Dhaka, Bangladesh and analysed by ion-exchange chromatography. Most
relevant validation parameters were evaluated using the standard validation procedure.
The linearity was more than 0.995 and recoveries for nitrite and nitrate were more than
96% and 97%, respectively. The Limit of detection (LOD) for nitrite and nitrate was 0.10
and 0.26 mg/L, respectively. Results showed that the highest nitrite and nitrate content
was 66.04±0.55 and 55.02±1.4 mg/kg, respectively. However, nitrite and nitrate levels
were lower than the prescribed value by international guidelines. Besides, temperaturebased recovery revealed that 80°C was the optimum temperature for recovering the nitrite
and nitrate from meat and meat products. This developed method applying ion-exchange
chromatography can monitor the content of nitrite and nitrate in meat and meat products to
ensure food safety.

Abstract
The aim of the present study was to evaluate the in vitro antiproliferative activity of ethanolic extract of leaves and fruits Citrus paradisi plant on HepG-2 liver cell lines by MTT (3-(4, 5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-terazolium bromide) assay and to isolate and characterize the antiproliferative compounds by TLC (Thin layer chromatography) and FT-IR (Fourier transforms Infrared) spectroscopy. Qualitative phytochemical screening tests were performed to detect phytochemicals compounds from the crude extracts. Antioxidant activity of the plant extracts were characterized by using DPPH (2,2-Diphenyl-1-picrylhydrazyl) free radical scavenging method. The results showed that antioxidant activity using DPPH were found to be increased in a concentration dependent manner and decreased cell viability and cell growth inhibition in a dose dependent manner. The findings from this study indicated that fruit extract exhibited good antiproliferation and antioxidant potential. The seven functional groups of phytocompounds such as carboxylic acid, amine salt, aromatic compounds, cyclic alkene, aldehyde, fluoro compounds and alkene were detected by FT-IR which indicated that fruit extracts of Citrus paradisi possessed vast potential as a medicinal drug especially in liver cancer treatment.

Abstract
Nowadays, increasing extended-spectrum β-lactamase (ESBL)-producing bacteria have become a global concern because of inducing resistance toward most of the antimicrobial classes and making the treatment difficult. In order to achieve an appropriate treatment option, identification of the prevalent species which generate ESBL as well as their antibiotic susceptibility pattern is essential worldwide. Hence, this study aimed to investigate the prevalence of ESBL-producing bacteria and assess their drug susceptibility in Fardis Town, Iran. A total of 21,604 urine samples collected from patients suspected to have urinary tract infection (UTI) were processed in the current study. The antimicrobial susceptibility of the isolates was tested by the disk diffusion method. The ESBL producing bacteria were determined by Double Disc Synergy Test (DDST) procedure. Bacterial growth was detected in 1408 (6.52%) cases. The most common bacterial strains causing UTI were found E. coli (72.16%), followed by K. pneumoniae (10.3%) and S. agalactiae (5.7%). Overall, 398 (28.26%) were ESBL producer. The highest ESBL production was observed in E. coli, followed by Klebsiella species. ESBL producers revealed a higher level of antibiotic resistance compared with non-ESBLs. In conclusion, ESBL production in uropathogens was relatively high. Carbapenems and Aminoglycosides were confirmed as the most effective treatment options for these bacteria.

Abstract
Background:The pattern of changes in bone microarchitecture and mineralisation are distinctly different in osteoarthritis (OA) and osteoporosis (OP). However, the pathogenesis of OA is closely related with OP, making subchondral bone a promising target for OA treatment [1]. A detailed comparison of subchondral bone in OA and OP may help understand the relationship of the two diseases.Objectives:To carry out a comprehensive analysis of regional and compartmental variations in subchondral bone architecture and mineralisation in OA and OP.Methods:Femoral heads were collected from patients undergoing hip arthroplasty surgeries for hip OA (N=16) or osteoporotic fracture (N=7). For OP group, osteochondral plugs were collected from fixed sites: anterior, posterior and superior. For OA group, an optimised sampling procedure, based on a new macroscopic grading method and modified OARSI microscopic grading system, was used to collect plugs from regions with varying severity of cartilage degradation. Plugs were scanned by micro CT (voxel size 4.88µm). Regions of interest for cortical plate (Ct) and trabecular bone (Tb) were segmented from reconstructed images using semi-automatic approach. Densitometric (tissue and bone mineral density: TMD and BMD) and architectural parameters (cortical plate thickness (Ct.Th), trabecular bone volume fraction (BV/TV), trabecular thickness (Tb.Th), etc.) were measured using commercially available software. Unmatched inter-group regional comparisons were made between OA microscopic grades (1 to 4) and OP. Matched intra-sample regional analysis was made between ‘mild’ (Grade 1 and/or 2) and ‘severe’ (Grade 3 and/or 4) OA. TMD was also subjected to paired comparison between cortical (Ct.TMD) and trabecular (Tb.TMD) compartments. Correlations between densitometric and architectural parameters were also explored.Results:Regional analysis showed that Tb.TMD in OA Grade 3 and 4 was significantly lower than in OP and Grade 1 and 2, while Tb.TMD in OP was not significantly different from OA Grade 1 and 2 (Fig 1A, F). Ct.TMD in OA Grade 4 was significantly lower than in OP, but no difference was found in other comparisons (Fig 1B, G). For BMD of trabecular bone (Tb.BMD) and architectural parameters including BV/TV and Ct.Th, values for OA Grade 3 and/or 4 were significantly higher than OP and Grade 1 and/or 2, but the difference between OP and Grade 1 and 2 was not significant (Fig 1C-E, H-J). Compartmental analysis showed that Ct.TMD was significantly lower than Tb.TMD in all groups (Table I). Tb.TMD was inversely correlated with Tb.BMD and BV/TV in both OA and OP; Ct.TMD and Tb.TMD were inversely associated with Ct.Th and Tb.Th respectively in OA (Table II).Conclusion:In both OA and OP, material density (TMD) of cortical plate was lower than trabecular bone. In hip OA, densitometric and architectural changes of subchondral cortical and trabecular bone were related to severity of cartilage degradation. In OA trabecular bone, the decrease in material density was compensated by increased bone volume, leading to higher apparent density (BMD); while in OP, loss of bone volume was correlated with, but not compensated by increased mineralisation, leading to lower apparent density.References:[1]Castaneda, S., et al.

Abstract
Background:Osteoarthritis (OA) is one of the leading causes for disability in adults. The diagnosis of OA is generally based on patient reported pain, other symptoms and radiographic changes which occur in late stages. There have been extensive research over the last 30 years to identify and validate molecular markers for early diagnosis of OA and a large range of potential biomarkers has been identified[1, 2]. However, most of these biomarkers are markers of structural and metabolic changes, and have poor correlation with pain and stiffness in knee OA. The publicly available data from the National Institute of Health Osteoarthritis Initiative (OAI) provides an opportunity to search for clinically useful biomarkers associated with the main symptoms in OA.Objectives:To identify molecular biomarkers which are associated with the main symptoms of knee OA.Methods:600 participants from 4791 men and women aged 45 to 79 who were Kellgren & Lawrence grade 1 or more were identified with biochemical markers data, radiographic and clinical features of OA. Nineteen biochemical markers measured in serum and/or urine were analysed for their association with primary clinical features of OA: Knee injury and Osteoarthritis Outcome Score (KOOS) pain and symptoms, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and stiffness score. Patient level analysis was carried out based on the worst affected knee. The association of molecular biomarkers with KOOS and WOMAC scores were assessed using univariate and multivariate linear and logistic regression, and receiving operator characteristic curves (ROC). Area under the curve (AUC) was calculated in order to determine if a combination of the biomarkers improve the associations with the outcome variables.Results:Only 3 of the 19 biomarkers investigated were associated with clinical symptoms. Serum cartilage oligomeric matrix protein (COMP) and chondroitin sulphate 846 (CS846) were associated with WOMAC pain and stiffness respectively, while, urinary C-terminal crosslinked telopeptide of type II collagen (CTXII) appeared to be highly associated with WOMAC stiffness, KOOS pain and symptoms (Table 1 / 2). The AUC from the univariate model for the association of biomarkers with WOMAC pain and stiffness were 0.5 (Table 1), while the AUC for unadjusted and adjusted multivariate model for the 3 biomarkers combined were 0.56 and 0.67 respectively (Figure 1).Table 1.Univariate logistic regression model.WOMAC PainWOMAC StiffnessBiomarkersOR (95%)AUC (p-value)OR (95%)AUC (p-value)sCS8461.0026 (0.9996, 1.0056)0.5200 (0.088)1.0047 (1.0013, 1.0081)0.5399 (0.007)sCOMP0.9419 (0.8912, 0.9954)0.5462 (0.034)1.0424 (0.9843, 1.1039)0.5317 (0.156)uCTXII1.0077 (0.9990, 1.0165)0.5300 (0.083)1.0099 (1.0005, 1.0194)0.5489 (0.039)Conclusion:Serum COMP and urinary CTXII are associated with pain in knee OA, while serum CS846 and urinary CTXII are associated with joint stiffness. The multivariate logistic regression model shows good discrimination for the association of biomarkers with clinical symptoms of OA. The data from the multivariate model suggests that a clinically useful biomarker may be created using AUC values for better specificity and sensitivity.References:[1]Lotz, M., et al.

Abstract
Osteoarthritis (OA) is a chronic degenerative disease of diarthrodial joints most commonly affecting people over the age of forty. The causes of OA are still unknown and there is much debate in the literature as to the exact sequence of events that trigger the onset of the heterogeneous disease we recognise as OA. There is currently no consensus model for OA that naturally reflects human disease. Existing ex-vivo models do not incorporate the important inter-tissue communication between joint components required for disease progression and differences in size, anatomy, histology and biomechanics between different animal models makes translation to the human model very difficult. This narrative review highlights the advantages and disadvantages of the current models used to study OA. It discusses the challenges of producing a more reliable OA-model and proposes a direction for the development of a consensus model that reflects the natural environment of human OA. We suggest that a human osteochondral plug-based model may overcome many of the fundamental limitations associated with animal and in-vitro models based on isolated cells. Such a model will also provide a platform for the development and testing of targeted treatment and validation of novel OA markers directly on human tissues.

Abstract
This paper analyzes the effects of charge on the nature of relativistic compact star candidates with anisotropic distribution in the framework of [Formula: see text] gravity. For this purpose, we consider Krori–Barua solutions and obtain the values of unknown constants as well as charge using observational data of Her X-1, 4U1820-30 and SAX J 1808.4-3658 star models. For three viable [Formula: see text] models, we investigate the behavior of energy density, transverse as well as radial pressures in the interior geometry of these stars. The validity of energy conditions, effect of anisotropic factor and stability of these stellar models are also examined. We conclude that the effect of charge leads to more stable structures of relativistic compact objects.

Abstract
This paper investigates the existence and stability of Einstein universe in the context of f(R, T, Q) gravity, where Q = R[Formula: see text] T[Formula: see text]. Considering linear homogeneous perturbations around scale factor and energy density, we formulate static as well as perturbed field equations. We parametrize the stability regions corresponding to conserved as well as non-conserved energy–momentum tensor using linear equation of state parameter for particular models of this gravity. The graphical analysis concludes that for a suitable choice of parameters, stable regions of the Einstein universe are obtained which indicates that the big bang singularity can be avoided successfully by the emergent mechanism in non-minimal matter-curvature coupled gravity.

Abstract
This study was planned to evaluate the effect of distillery yeast sludge (DYS) as a protein source on growth performance, nutrient digestibility and slaughtering parameters in Japanese quail birds. For this purpose, six hundred day-old quails were randomly distributed into six dietary treatments. These dietary treatments were; G1 (Control Group) fed a basal diet (CP 24%, ME 2900 kcal/kg) without DYS, while other dietary treatments were G2, G3, G4, G5 and G6 fed basal diet containing DYS @ 1.5, 3.0, 4.5, 6.0 and 7.5%, respectively. It was observed that feed intake and weight gain tended to increase (P < 0.05) up to 3% DYS. Better (P < 0.05) feed conversion ratio (FCR) was observed in birds fed diet containing DYS at the level of 1.5 and 3%. Dry matter and crude protein digestibility decreased with increasing levels of DYS (P < 0.05). Cost of production per 100 g of weight gain was also less in birds fed diet containing 3% DYS. Study revealed that inclusion of distillery yeast sludge in the diet of Japanese quails up to 3% improves the growth performance and economics efficacy.

Abstract
In this paper, we study phase space analysis of FRW universe model by taking a power-law model for bulk viscosity coefficient. An autonomous system of equations is developed by defining normalized dimensionless variables. We find corresponding critical points for di.erent values of the parameters to investigate stability of the system. It is found that the presence of power-law model of bulk viscosity appears as an e.ective ingredient to enhance the stability of the respective universe model.

Abstract
We conducted a cross-sectional study during 2013 to quantify the serological prevalence of peste des petits ruminants (PPR) infection and to investigate host factors associated with PPR infection in small ruminants in Libya. A two-stage sampling design was carried out. A total number of 148 flocks owning at least 100 heads each were randomly selected. Sixteen to forty-eight samples were collected from each selected flock. A total number of 3,508 serum samples from unvaccinated animals were collected and analysed at IZSLER Brescia, Italy, by using competitive ELISA, IDvet innovative diagnostics (IDvet 310, France). The overall serological prevalence among SR was 33% (95% CI: 31.4-34.5). Significant differences between the prevalence in the geographical branches were observed. The lowest prevalence level was observed in Zawiyah branch (16.1%), whereas the highest value was obtained for the Sabha branch (56.8%). Considering the age, a serological prevalence of 24.7%, 31.5% and 42.1% was observed in SR <1 year, between 1 and 2 years and more than 2 years, respectively. Statistically significant differences (p < .001) in the sero-prevalence levels were also observed between the age groups. Our findings suggest that the southern part of Libya could be more exposed to the infections coming from the neighbouring countries and this should be better investigated to correctly identify wherever specific entry points can be considered at higher risk than others. The results also confirmed the endemic status of PPR in Libya, with a constant exposure to the infection of the animals during their life. In the framework of the global strategy for control and eradication of PPR, our results, even if obtained by a preliminary study, can contribute to the assessment of the epidemiological situation of PPR in Libya as required by the Stage 1 of the plan.

Abstract
This experiment was conducted to assess nutritional potential of corn steep liquor (CSL) as an alternative protein source in broiler's diet. A total of 280-day-old unsexed broiler chicks were randomly distributed into four experimental groups in a simple randomised experimental design (each group had seven replicates; 10 birds per each). Four iso-nitrogenous and iso-caloric broiler starter and finisher diets (C, LCSL, MCSL and HCSL) were formulated containing 0%, 5%, 10% and 15% CSL respectively. Results revealed that chicks fed MCSL diet had significantly (p ≤ .05) the heaviest Body weight, highest Body weight gain and the lowest feed conversion ratio followed by those fed HCSL diet. In the starter period, LCSL and MCSL diets resulted in better (p ≤ .05) dry matter (DM) (89.57%) and crude protein (67.67%) digestibilities respectively. In the finisher period, DM, crude fibre and fat digestibilities were not affected by CSL inclusion levels; while crude protein digestibility was significantly (p ≤ .05) high in the groups fed LCSL and HCSL diets. The CSL inclusion had no effect on blood haematology except serum uric acid, which tended to increase with increasing CSL levels. No microscopic changes were exhibited on liver, heart, kidneys and intestine of birds across all dietary treatments. However, crops in birds fed HCSL diet showed moderate to severe hypertrophy and hyperplasia of the mucosal lining. The study showed that CSL could be added up to 15% in broiler's diet without any adverse effect on bird's performance.

Abstract
This paper investigates the behavior of anisotropic compact stars in the background of R + αRμνTμν gravity model. For this purpose, we use Krori–Barua metric solutions where constants are calculated using masses and radii of compact stars like Her X-1, SAX J 1808.4–3658, and 4U1820–30. We analyze regular behavior of effective energy density, and radial and transverse pressures in the interior of compact stars. We also discuss energy conditions, effect of anisotropic factor, and stability criteria of these stars. It is concluded that the considered compact star models satisfy all the energy conditions and remain stable against the anisotropic effect in this gravity.

Abstract
Summary
The family Taeniidae is of great importance in the medical and veterinary fields, particularly in the tropics and subtropics. Identification of eggs of different Taenia spp. in the final host by morphological examination is difficult owing to their similarity. Therefore, a multiplex polymerase chain reaction (PCR) targeting a mitochondrial gene was applied to identify morphologically indistinguishable eggs. Fecal samples from 100 domestic dogs, from the Mazandaran province in Iran, were examined using the flotation/sieving method followed by multiplex PCR. Taeniid eggs were observed in 24 % samples, of which 12 %, 10 %, and 2 % were infected with Echinococcus granulosus, Taenia spp., and both E. granulosus and Taenia spp., respectively. E. multilocularis was absent in these samples. The prevalence of E. granulosus in the examined domestic dogs as definitive hosts in north of Iran was high (14 %). Therefore, people living in this region of Iran are in danger of acquiring hydatid cyst, which is a serious public health problem.

Abstract
CONTEXT Infectious diseases including HIV and viral hepatitis constitute a major health issue, with high prevalence among injecting drug users (IDUs). AIMS The present study assessed the frequency of HIV, and hepatitis B and C viruses (HBV and HCV) among 200 IDUs, hospitalized between 2001 and 2006, in Shahid Beheshti Hospital of Kashan, Iran. SETTING AND DESIGN A population-based cross-sectional study in Iran. MATERIALS AND METHODS A total of 200 subjects participated in this study. Serological markers including HBsAg, anti-HCV antibodies and HIV were assessed by ELISA method using Monobid kits made in US. Demographic data was collected by using a questionnaire, which was designed by a researcher. STATISTICAL ANALYSIS USED Frequencies were determined by employing SPSS:PC version 15.0, and Chi-square and Fisher's exact tests were used to compare proportions. RESULTS The mean age of subjects was 36.5 ± 10.2 years. Approximately 88.5% (177 cases) were male and 11.5%. (23 cases) were female. The frequency of positive infection test results for males with respect to HBV, HCV, and HIV was 4% (8 cases), 10.5% (21 cases), and 1.5% (3 cases); and for females it was 0.5% (1 case), 1.5% (3 cases), and 0% (0 case), respectively. CONCLUSION This study demonstrates that the frequency of HBV, HCV, and HIV infection in the IVD user in Kashan, Iran, is relatively high and this condition is more serious in male than female drug addicts. It is very important, especially for health providers and policy makers, to recognize the risk factors of HBV, HCV and particularly HIV infection in this area and design effective preventive programs.

Abstract
The mitogenic substance P receptor (NK-1 subtype) is expressed in many primary human tumors with the highest frequency of expression appearing in astrocytomas and glioblastomas (75% and 100%, respectively). Recently, we showed that substance P neuropeptide induces DNA synthesis in the human astrocytoma U-373MG cells by activating the mitogen-activated protein (MAP) kinase pathway leading to the induction of c-Fos and c-Myc expression. The induction of these immediate early genes is necessary for the progression of cells form G1 to S phase of the cell cycle. In this study, we demonstrate that U-373MG cells are highly sensitive to the growth-inhibitory action of rapamycin at nanomolar concentrations (IC50 <1 ng/ml). We also show that SP peptide stimulates protein synthesis in the U-373MG cell line by activating a rapamycin-sensitive signaling pathway. Further, we demonstrate that SP is potent in stimulating PHAS-I protein (also known as 4E-BP1) phosphorylation and p70 S6 kinase (p70(S6K)) phosphorylation and enzymatic activity, and that this stimulation is inhibited by subnanomolar concentrations of rapamycin. In contrast, rapamycin was not at all effective in repressing SP-induced activation of MAP kinase pathway, c-Fos phosphoprotein expression, and DNA synthesis in U-373MG astrocytoma cells.

This paper presents a face hashing technique for fast face recognition. The proposed technique employs the two existing algorithms, i.e., 2-D discrete cosine transformation and K-means clustering. The image has to go through different pre-processing phases and the two above-mentioned algorithms must be used in order to obtain the hash value of the face image. The searching process is increased by introducing a modified form of binary search. A new database architecture called Facebases has also been introduced to further speedup the searching process.

Abstract
The study was conducted to investigate the chemical composition of distillery yeast sludge and its inclusion in broiler diets to replace canola meal. Raw distillery yeast sludge was washed with water using water and sludge in the ratio 6:1, respectively. Proximate analysis of raw distillery yeast sludge and washed distillery sludge was carried out for crude protein (CP), true protein (TP), ether extract (EE), ash, acid insoluble ash and nitrogen free extract (NFE) determination. Mineral contents and amino acid profile of raw distillery yeast sludge and washed distillery sludge were also determined. After chemical evaluation, four iso-caloric and iso-nitrogenous broiler starter and finisher diets were prepared in mash form using 0 (control), 4, 8 and 12% levels of washed distillery sludge replacing canola meal. One hundred and twenty day-old broiler chicks were randomly distributed into 12 experimental units in such a way that each diet was offered to three experimental units, each comprising of 10 chicks. It was observed that washing affected the nutrients either by decreasing or increasing their concentration. It decreased the total mineral contents whereas CP, TP, EE and NFE contents increased. Washing also increased amino acid profile. Average feed intake and weight gain were higher in birds fed diet containing 8% washed distillery sludge and lower in birds fed diet containing 0% washed distillery sludge. Feed cost per kg live weight gain decreased significantly as the level of washed distillery sludge was increased in the diet. Average heart, liver and pancreas weights decreased with increased level of washed distillery sludge in the diet. The study revealed that after washing, distillery yeast sludge can be used successfully in broiler diets up to the level of 8% without any adverse effect on broiler’s performance.

Abstract
BACKGROUND The aim of the present study was to determine the molecular characteristics of Echinococcus granulosus from paraffin-embedded tissues of hydatid cysts isolated from human and protoscoleces of hydatid cysts from sheep, cattle and camel isolates using PCR- RFLP of ITS1- rDNA analysis in Golestan Province, northern Iran. METHODS E. granulosus isolates from human patients infected with hydatid cyst and protoscoleces from hydatid cysts of sheep, cattle and camel isolates were collected from different hospitals and the abattoir throughout the Golestan Province. In all, 60 E. granulosus genomic DNA were extracted and examined by PCR - ITS1 of rDNA and amplified using BD1 / 4S and EGF1 / EGR2 primers, followed by RFLP using Alu1, Msp1 and TaqI restriction enzymes. RESULTS The PCR-ITS1 products obtained from sheep, cattle and human isolates were similar to sheep strain (1000 bp and 391 bp). Majority of the camel samples yielded 295 bp DNA bands. RFLP -ITS1 of E. granulosus with Taq1 in human, sheep and cattle isolates showed similar patterns in the number and size of DNA. RFLP methods in camel isolates showed a different genotype, using Taq1, whereas no DNA bands were observed using Alu1 in camel and human isolates. Therefore, two clearly distinguishable banding patterns of E. granulosus were obtained with the three enzymes, which separating human, sheep and cattle isolates from the camel origin. CONCLUSION The results indicate the possible of transmission of the G1 and G6 genotypes of E. granulosus between livestock animals and human in Golestan Province.

Abstract
BACKGROUND New cases of visceral leishmaniasis (VL) have been reported recently in some parts of Mazandaran Province, north of Iran where the first human case of VL was reported in 1949. This study aimed to determine the present status of Leishmaniainfantum infection among humans and domestic dogs using serological and molecular methods in central parts of Mazandaran Province. METHODS In this cross-sectional study, blood samples were randomly collected from 402 humans and forty-nine domestic dogs throughout 2009 and 2010 in the central part of Mazandaran Province including Semeskadeh and Kiakola districts where recent cases of human visceral leishmaniasis had been reported there. All the collected samples were tested by direct agglutination test (DAT) for the detection of anti-Leishmania infantum antibodies as well as convenience PCR assay on whole blood samples for detection of leishmanial infection and identification of Leishmania species. RESULTS None of 402 collected human (402) and dog (49) blood samples showed anti Leishmaniainfantum antibodies at titers 1:3200 and 1:320 as cut-off values of DAT, respectively but only 2 of domestic dogs (4.1%) were found PCR-positive corresponding to L.infantum. CONCLUSION This study confirms the circulation of L. infantum at least among domestic dogs and highlights the sporadic pattern of VL in the studied areas. Further investigations regarding to sand flies fauna and wild canines as reservoir hosts of the disease, are recommended.
