Abstract
Cystic echinococcosis (CE), caused by Echinococcus granulosus sensu lato (s.l.), represents one of the most significant zoonotic diseases globally, affecting both humans and animals. The objective of this study was to ascertain the prevalence of E. granulosus sensu lato in sheep and goats in a pilot region with a one-year slaughterhouse follow-up period and to determine the genetic differences and haplotypes among sheep, goat, and dog isolates. To this end, the prevalence of CE cysts was determined by monitoring the slaughter of sheep and goats at least three days a week at a slaughterhouse in the Siirt province of Türkiye during 2023. Additionally, faecal samples were collected from stray dogs and analysed using both flotation and molecular techniques. The presence of CE cysts was identified in 569 (11.12 %) of the 5119 sheep and 66 (2.31 %) of the 2860 goats after slaughtering. The highest positivity was observed in November (20.39 %), while the lowest was recorded in July (5.62 %). Of the sheep that detected positive, 25 (4.39 %) were less than one year old, while 544 (95.61 %) were older than one year. Of the infected sheep, 26 (4.57 %) were male and 543 (95.43 %) were female. 204 (35.85 %) sheep exhibited fluid-filled CE cysts, 338 (59.40 %) displayed calcification, and 27 (4.75 %) demonstrated the presence of newly developed cysts. The highest positivity was observed in December (5.83 %), while the lowest was recorded in May (0.62 %) in goats. Of the positive goats, two (3 %) were less than one year old, while the remaining 64 (97 %) were older than one year. Of the goats infected with CE cysts, 10 (15.15 %) were male and 56 (84.85 %) were female. Of the cysts, 56.1 % were fluid-filled, 42.4 % were calcified and 1.5 % were newly developed. Following DNA sequence analysis of CE cyst isolates obtained from the slaughterhouse, all 61 sheep sequences were identified as E. granulosus s.s. (G1/G3). Of the 13 goat isolates, seven were identified as E. granulosus s.s. (G1/G3), while the remaining six were classified as E. canadensis (G6/G7). The centrifugal flotation method was employed to detect the presence of Isospora spp. oocysts in eight dogs, Toxocara canis and hookworm eggs in three dogs each, and Dipyllidium caninum eggs in one dog. A total of 54 dog faeces were examined. No Taeniid eggs were observed in any of the dogs. Following PCR analysis of the mt-CO1 gene region in the dog faecal samples, four samples were positive for a 875 bp band. Only one of these bands was suitable for sequence analysis, which confirmed it as E. granulosus s.s. (G1/G3).

Endale H, Mathewos M. Prevalence and associated risk factors of hydatidosis in cattle slaughtered at Wolaita Sodo municipality abattoir. Vet Med Sci 2024; 10:e70008. [PMID: 39215458 PMCID: PMC11364586 DOI: 10.1002/vms3.70008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 07/14/2024] [Accepted: 08/06/2024] [Indexed: 09/04/2024] Open
Abstract
BACKGROUND Hydatidosis, caused by the larval stage of the tapeworm Echinococcus granulosus, affect cattle by forming hydatid cyst in thier lungs, livers and pose great financial loss in animal production and country's economy by both direct and indirect effect. Despite its great economic and health importance, there is an absence of current information on cystic echinococcosis in cattle slaughtered at Wolaita Sodo municipality abattoir in Ethiopia. OBJECTIVES Current investigation determines the prevalence, organ distribution and fertility of hydatid cysts in cattle slaughtered at the Wolaita Sodo municipality abattoir in Ethiopia. METHODS A cross-sectional study was conducted from February, 2023, to October, 2023, at Wolaita Sodo municipality abattoir in southern Ethiopia, through regular meat examinations and cyst characterisation to determine the prevalence, organ distribution and fertility of hydatid cysts. RESULTS The overall prevalence of hydatidosis recorede in current study was 17.9% (69/384) and has shown a statistically significant association (p < 0.05) with the body condition of cattle. However, there was no statistically significant association (p > 0.05) between the prevalence of hydatidosis and other risk factors such as sex, breed, production system and origin of animals. This study showed that the lungs and liver were the most affected organs in cattle, followed by the spleen and kidneys. On cyst characterisation, the majority of hydatid cysts were found sterile (55.4%) followed by fertile (38.8%) and calcified (8.7%) cysts. Out of 125 fertile hydatid cysts tested for survival, 18.8% (58/321) were viable and 20% (67/321) were nonviable. CONCLUSION The finding of this study shows that cystic echinococcus was important health threat of the cattle and widespread in the internal organs of affected cattle causing significant economic loss by condemning edible organs that are not suitable for human consumption. Therefore, urgent and integreted preventive action is needed to disrupt the life cycle of cystic echinococcosis to tackle subsequent financial loss and risk of zoonosis to humans in the study area.

Abstract
Cystic echinococcosis (CE) is a zoonotic disease of great importance worldwide. This study was conducted to determine the prevalence and antigenic profile of Echinococcus cysts (CE cysts) in camels and cattle. The lungs, livers, hearts, and kidneys of 560 animals, comprising 304 camels and 256 cattle slaughtered in the Maiduguri abattoir, were examined for CE. Blood samples were collected for serology. Protein profiles of CE fluids were analyzed using indirect Enzyme Linked Immunosorbent Assay while Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS-PAGE) was used to characterize the electrophoretic pattern of different CE cyst fluid samples. The overall prevalence of CE was 8.4%, 14.14% (95% CI = 10.65-18.54%) in camels and 1.60% (95% CI = 0.46-4.09%) in cattle. Adult camels 41 (16.21%) (95% CI = 12.15-21.27%) had a higher prevalence than the young camels 2 (3.92%) (95% CI = 0.33-13.97%) (p = 0.038). In cattle, only adults 4 (2.0%) had cysts. Higher prevalence of CE was recorded in male 22 (16.42%) (95% CI = 11.03-23.68%) than female 21 (12.35%) (95% CI = 8.16-18.21%) camels [p = 0.399] while only female cattle 3 (2.2%) had cysts. Higher prevalence of CE was recorded in the livers of 34 (11.18%) (95% CI = 8.08-15.25%) than in the lungs 25 (8.22%) (95% CI = 5.59-11.90%) of camels [p = 0.273]. Of the 47 cysts collected, 43 (91.49%) and 4 (8.51%) were from camels and cattle, respectively. A total of 18 (38.30%) fertile, 17 (36.17%) non-fertile, and 12 (25.53%) calcified cysts were recovered in animals. Overall seroprevalence of 52.63% (95% CI = 47.02-58.18%) and 35.55% (95% CI = 29.93-41.59%) were observed in camels and cattle in this study. The SDS-PAGE of camel CE cyst fluids revealed protein bands at 64kda, 91kda, 160kda, and 200kda molecular units while the purified cyst fluids revealed bands at 64kda, 91kda, 120kda, 160kda, and 200kda. Regular meat inspections and the exclusion of dogs from abattoir premises are strongly encouraged. Investigation into local prevailing factors encouraging transmission should be carried out.

Abstract
Cystic echinococcosis is caused by the metacestode of the zoonotic flatworm Echinococcus granulosus. A cross-sectional study was conducted from October 2020 to August 2021 at the Gessa municipality abattoir in southern Ethiopia, through regular meat examinations and cyst characterization to determine the prevalence, organ distribution, and fertility of Cystic echinococcosis. The overall prevalence of Echinococcus granulosus sensu lato was 17.9% (69/384) and has shown a statistically significant association (p < 0.05) with the body condition of cattle but not with other putative risk factors (p > 0.05). The odds of poor body condition cattle infected with CE was 1.29 times higher than medium body condition (OR = 0.506; CI = 0.566–2.96). Based on organ distribution of cysts, the lungs and liver were the most affected organs having a statistically significant difference (p < 0.05) with the prevalence of CE. Based on the size of cysts, small (47.9%) size cysts revealed the highest prevalence as compared with large (33.3%) and medium (18.8%) sized cysts. On cyst characterization, the majority of Cystic echinococcosis were sterile cysts (55.4%) followed by fertile (38.8%) and calcified (8.7%) cysts and revealed a statistically significant difference (p < 0.05). Cyst number, organ localization, fertility of cyst, and cyst size have shown a strong positive correlation (r = 0.8686, r = 0.8393, r = 0.9506, and r = 0.9189) with the prevalence of CE, respectively. The presence of an overall high prevalence of Echinococcus granulosus sensu lato in the present study required urgent action to interrupt the life cycle of Cystic echinococcosis and further studies using molecular techniques to characterize the circulating genotypes to prevent the risk of zoonosis in humans in the study area.

Abstract
Echinococcosis is considered a cosmopolitan zoonosis caused by different species of small taeniid tapeworms of the genus Echinococcus and is regarded as a neglected zoonosis. Cystic and alveolar echinococcoses are endemic diseases of Tibetan, Pamir, and Iranian plateaus. All of the countries within the Iranian plateau are affected by echinococcosis. Pakistan, Turkey, and Iran are the three most populous countries of the region, in which echinococcosis is highly endemic. The three neighboring countries share strong cultural and socioeconomic ties. The present study aimed to provide a broad review of the status of cystic and alveolar echinococcosis, summarizing the current knowledge about geographical distribution, molecular epidemiology, and transmission dynamics of Echinococcus granulosus sensu lato and Echinococcus multilocularis in this region. Additionally, we aimed to understand disease burden and risk factors as basic requirements for establishing a surveillance system and planning prevention and control programs. A considerable body of information is available on different aspects of echinococcosis in this region; however, several information and research gaps need to be filled before planning control programs. None of the countries in the region have an elaborate echinococcosis control program. Effective control programs require multi/intersectoral coordination within a One Health approach with a long-term political and administrative commitment and enhanced international collaboration among the three countries.

Abstract
Hydatidosis is cystic parasitosis caused by a larval stage of Echinococcus granulosus with immense economic and public health significance. A cross-sectional study was conducted from November 2016 to April 2017 in the city municipal abattoir of Southern Ethiopia with the aim of determining prevalence and cyst fertility and estimating financial losses associated with organ condemnation. The visceral organs of about 400 cattle were examined for hydatid cysts after slaughter. Postmortem examination, cyst characterization, and direct financial loss estimations were carried out. From the total 400 cattle examined, 208 (52%) were found positive for hydatid cyst infection in one or more of their organs. A total of about 395 hydatid cysts were collected from different organs of the infected cattle. Anatomical distribution of the cysts indicated that around 245 (62.03 %) were found in lung, 91 (23.04%) in liver, 26 (6.58%) in heart, 21 (5.32%) in spleen, and 12(3.04%) in kidney. From the total 395 cysts collected, 166 (42.03%) were found fertile and 229 (57.97%) nonfertile. From the total fertile cysts, 70 (42.17%) were found to be viable and 96 (57.83%) nonviable. Furthermore, from the total nonfertile cysts, 204 (89.08%) and 25 (10.91%) were sterile and calcified, respectively. Distribution of cyst calcification was higher in liver and fertility rate was higher in the cysts of lungs. The statistical analysis showed that the prevalence of hydatidosis was found to be significantly associated with age of the studied animals (P<0.05). However, there was no significant association (P>0.05) between the prevalence of bovine hydatidosis and other risk factors such as sex, breed, body condition, and origin of animals. The annual financial loss calculated from organ condemnation was estimated about 58,114.62 USD. This study revealed that hydatidosis is a highly prevalent disease in the study area with a huge economic losses. Therefore, there is a need for immediate intervention by breaking the life cycle of the parasite to alleviate its economic impact and zoonotic risks to humans.

Abstract
This study describes ultrasonographic observations of five hepatobiliary diseases in buffalo (Bubalus bubalis). Fifty buffalo, including 20 clinically normal and 30 hepatobiliary diseased buffalo were enrolled in the study. Complete clinical, radiographic and ultrasonographic examinations and laboratory analyses were conducted. Focal parenchymal lesions including liver abscess (n = 12) and hepatic cyst (n = 6), diffuse parenchymal lesion (hepatobiliary cirrhosis, n = 5) and obstruction of hepatobiliary passages including cholestasis (n = 4), and hepatocholelithiasis (n = 3) were successfully imaged by ultrasonography. Hepatic abscess imaged as a hypoechoic to echogenic circumscribed mass of various diameters with a distinct echogenic capsule. Hepatic cyst imaged as a pear-shaped sac with a bright echogenic margin, anechoic content, and distal acoustic enhancement. In hepatobiliary fibrosis, the liver showed linear bands of increasing echogenicity with less distinct imaging of the portal vasculature. Cholestasis was imaged as dilatation of the gallbladder (GB) with wall thickening and homogeneous or heterogeneous contents. Hepatocholelithiasis imaged as an echoic structure within the hepatic parenchyma, or within and around the GB and bile duct, with more echogenicity of the hepatic parenchyma than normal. Ultrasonography can be an efficient rapid, noninvasive tool for screening of common hepatobiliary diseases in buffalo under field conditions.

Abstract
A cross-sectional study was conducted from November 2016 to April 2017, to estimate the prevalence of major gross lung lesions in cattle slaughtered at Hawassa Municipal Abattoir, southern Ethiopia. A total of 563 male cattle were examined by antemortem examination, while postmortem lung lesions were done using standard inspection procedures. Association between prevalence and the explanatory variables was estimated by way of chi-square/Fischer's exact tests using statistical packages for social science (SPSS) software. Upon postmortem examination, 96.6% (544/563) of cattle examined had various gross lung lesions. The most important lesions identified were hydatidosis, emphysema, congestion, and atelectasis with prevalence of 45.3%, 19.2%, 18.1%, and 6.4%, respectively. Based on origins of slaughtered animals, hydatid cyst, emphysema, and congestion were common in cattle that came from Tula area with prevalence of 46.3%, 20.4%, and 20%, respectively. The animals from Arsi-negelle and Hawassa were mostly affected by hydatid cyst with prevalence of 44.4% and 42.5%, respectively. Statistically significant association (p = .038) was observed between prevalence of atelectasis and body condition of slaughtered cattle. In conclusion, the prevalence of hydatidosis was the major lesion in the lung of slaughtered cattle at Hawassa Municipal Abattoir. Therefore, appropriate disease control strategies should be put in place.

Fresh dog faecal samples were collected, preserved in 70 % ethanol, and later screened for presence of taeniid eggs using zinc chloride floatation method. Positive samples were confirmed by a copro-PCR (polymerase chain reaction) for E. granulosus using NADH dehydrogenase sub-unit 1 gene (NADH1) as a target molecular marker. Structured questionnaires and focus group discussions were used to collect quantitative and qualitative data for risk factor identification. Study sub-counties were selected by simple random sampling. Overall apparent prevalence of taeniid infection in dogs of 14.9 % (39/261, confidence interval 10.6-19.2) in both districts was recorded using the faecal floatation test. The sensitivity of the faecal floatation test was found to be 78 % (25/32), while the specificity was 93 % (215/229). Copro-PCR results revealed a true prevalence of 14.4 % (9.91-19.0, 95 % CI) in dogs in Moroto district and 7.4 % (2.14-12.60, 95 % CI) in Bukedea district. The overall true prevalence of cystic echinococcosis (CE) was 12.2 % (8.70-15.76, 95 % CI) in both districts. The major risk factors identified using logistic regression were uncontrolled access of dogs to animal slaughter facilities, higher cattle herd sizes and lack of knowledge about the disease. It was recommended that restricting dog access to infected tissues and public health education about epidemiology of CE should be done.

Abstract
Despite alarming statistics on cystic echinococcosis (CE) in humans and the importance of dog and ruminant populations, no epidemiological investigations have been performed on CE in Sidi Kacem Province (North-West of Morocco). A part of large research project was devoted to determine the status of CE in ruminants. This paper reports the results of the investigations carried out in the 10 abattoirs of this region, over four successive years (April 2009–March 2013). A total of 1,302 sheep, 652 head of cattle, and 136 goats were postmortem examined and hydatid cysts were collected and examined. The overall CE prevalence of infection was 42.9% in cattle, 11.0% in sheep, and 1.5% in goats. The prevalence shows significant association with age in sheep and cattle; sheep above 3 years and cattle above 5 years are highly infected (64.0% and 72.2%, resp.). Only liver and lungs are found to be infected. Molecular analyses identified G1, G2, and G3 of E. granulosus sensu stricto in liver and lung samples. Cyst fertility was significantly higher in sheep (54.9%) than in cattle (50.3%). These findings suggest that control measures should target not only sheep but also cattle.

Abstract
Slaughterhouses provide a safeguard that prevents the public from consuming meat of poor quality or meat which may be infected with zoonotic diseases. This work reviews a 3-year database of cattle that were slaughtered and inspected between 2010 and 2012 at Dodoma abattoir, Tanzania. In addition, meat inspection was undertaken for 1 month (December 2013). The aim of this study was to establish causes of organ and carcass condemnations and their financial implications as well as the magnitude of slaughter of pregnant cows at Dodoma abattoir. During retrospective study, it was found that a total of 9015 (10.5%) lungs, 6276 (7.3%) intestines, 5402 (6.3%) livers, 3291 (3.8%) kidneys and 41 (0.05%) carcasses were condemned. Pulmonary emphysema (3.4%), fasciolosis (4.5%), pimply gut (5.7%), kidney congenital cysts (1.9%) and hydatidosis (3.1%) were major causes of organ condemnations. This large number of condemned edible organs and/or carcasses implies that public health considerations result in deprivation of valuable protein. Occurrence of hydatidosis, cysticercosis, fasciolosis and tuberculosis illustrates the possible public health problem and presence of environmental infections. Of the 794 cows slaughtered in December 2013, 46% were pregnant. Financial loss as a result of organ and/or carcass condemnations was estimated at $9892. Condemnation of organs and/or carcasses and indiscriminate slaughter of pregnant cows represent a significant loss of meat and revenue and a reduction in growth of future herds, which has a negative effect on the livestock industry. This justifies appropriate surveillance and disease control programmes coupled with strict enforcement of legislation governing animal welfare to curb the slaughter of pregnant animals.

Abstract
OBJECTIVES The present study was designed to gain information about the ultrasonographic features of livers with cystic echinococcosis, as well as to evaluate the use of ultrasonography for diagnosis of such disease in sheep. DESIGN This was a retrospective study during the period April 2011 to March 2013. PARTICIPANTS A total of 22 Baladi sheep (aged three to six years) were included in this study. Based on clear hepatic ultrasonographic findings, all animals were classified into two groups: those with hepatic cysts (n=9) and without liver cysts (healthy liver, n=13). RESULTS Biochemically, serum concentrations of γ-glutamyl transferase, aspartate aminotransferase, total bilirubin and globulins were significantly increased (P<0.01), while albumin was lowered (P<0.01) in sheep with cystic livers. Ultrasonographic findings of diseased sheep livers revealed the presence of rounded, anechoic and unilocular hydatid cysts with ellipse circumference ranged from 6-10 cm. The borders of cysts were mostly well defined. The interior of cysts contained echogenic particulate materials, septations, or fine echoes. At the 10th intercostal space, the ventral margin, size, thickness and angle of livers were higher (P<0.01), while the diameter of portal vein was lower (P<0.01) in sheep with liver cysts than control ones. Furthermore, at the 9th intercostal space, the circumference of the gall bladder was decreased in sheep with hepatic cysts (P<0.01). The sensitivity, specificity, and positive and negative predictive values of ultrasonography for diagnosis of hepatic hydatid cysts were 80 per cent and 100 per cent, and 100 per cent and 83 per cent, respectively. CONCLUSIONS Cystic echinococcosis is associated with a number of anatomical alterations in the liver tissues that can be easily recognised by ultrasound. Furthermore, ultrasonography alone or in combination with analysis of biochemical parameters reflecting liver function could be helpful for diagnosis of hepatic hydatid cysts in sheep.

Abstract
A cross-sectional study was conducted from October 2007 to November 2008 to estimate the prevalence of hydatidosis in slaughtered cattle from two abattoirs in Mongu, Western Province, Zambia, using prospective and retrospective data. Out of the 4061 cattle examined during postmortem inspection, 84 (2.1%) were positive for hydatidosis. No cases were detected from Kaoma and Shangombo districts; however, prevalence ranged from 0.6% to 2.5% in districts where it was present. Sex was found to be positively associated with hydatidosis (P = 0.035) with female cattle being more likely to have hydatidosis (OR = 1.62). In the retrospective study (1994 to 2007), annual prevalence of hydatidosis ranged from 1.56% (n = 12,641) in 2006 to 4.7% (n = 2633) in 2001 with an overall prevalence of 3% (4689/158,456). This value is comparable to that observed in cattle slaughtered between October 2007 and November 2008 (2.1%). Hydatidosis was observed in the lungs (51.2%), liver (47.6%), and kidneys (1.2%). The percentage of viable cysts was 43.7%. This study confirms the presence of hydatidosis in cattle in Western Province of Zambia and estimates economic losses due to organ condemnations. Data presented herein provides a useful baseline for developing policy and intervention measures.

Abstract
A cross-sectional study aimed at determining the prevalence and cyst characteristics and estimating the financial loss due to cystic echinococcosis (hydatidosis) in cattle slaughtered at Wolayita Sodo municipal abattoir was conducted from November 2009 to April 2010. Out of 546 cattle examined, 92 (16.85%) were found to harbor visible hydatid cysts. Significantly higher infection was detected in local (P < 0.05) than crossbred cattle. No significant variation was observed with regard to origin, sex, and body condition status of animals. Regarding organ distribution, infections of the lung, liver, spleen, and kidney were 57.78%, 35.46%, 8.75%, and 4.01%, respectively. Of the total 1,097 hydatid cysts counted, 952 (86.78%), 136 (12.4%), and eight (0.82%) were found to be small-sized, medium-sized, and large-sized, respectively. Likewise, out of 450 cysts assessed, 138 (30.67%) were fertile, 241 (53.56%) sterile, and 71 (15.78%) calcified. Of the 138 fertile cysts subjected for viability test, 13 (9.42%) were viable while 125 (90.57%) were nonviable. Moreover, assessment of annual economic loss due to bovine hydatidosis at Wolayita Sodo municipal abattoir from offal condemnation and carcass weight loss was estimated at 410,755.90 Ethiopian Birr (ETB; 30,202.64 US$; 1 US$ = 13.60 ETB). Despite the moderate magnitude of infection detected currently, there seems to be an existing socioeconomic situation favorable for hydatidosis, and hence, it remains one of the most important diseases warranting serious attention for prevention and control actions in Wolayita zone. Hence, establishment of well-equipped standardized abattoirs, creation of public awareness, and control of stray dogs are of paramount importance.

Abstract
AbstractEchinococcosis is a zoonotic infection caused by adult or larval (metacestode) stages of cestodes belonging to the genusEchinococcus. The purpose of this study was to evaluate the antigenic ability of hydatid cyst fluid antigen for the diagnosis of hydatidosis in cattle using enzyme-linked immunosorbent assay (ELISA) and indirect haemagglutination test (IHA). The source of the antigens for the serological tests was fertile crude cyst fluids collected from naturally infected sheep at the Addis Ababa abattoir. A total of 502 sera were collected from 329 uninfected cattle and 173 hydatid-infected cattle which were confirmed by post-mortem examination. Most cysts were sterile and multiple organ infection predominated. Of 173 infected cattle, 166 (96.0%; confidence interval (CI) 91.8–98.4) were positive using ELISA while 7 (4.0%) were negative. Of 329 sera from uninfected cattle, 274 (83.3%; CI 78.8–87.2) were found to be negative and the remaining 55 (16.7%) were positive by ELISA. Of 173 infected cattle, 151 (87.3%; CI 81.4–91.9) were positive and 22 (12.7%) were negative by IHA. Of 329 negative sera tested using IHA, 266 (80.9%; CI 76.2–85.0) were negative and the remaining 63 (19.1%) were positive. The false positive and negative values of ELISA were 4.0 and 16.7%, respectively, and the corresponding values of IHA were 12.7 and 19.1%. The sensitivity and diagnostic efficiency of IHA were 87.2 and 83.6%, respectively. Crude hydatid cyst fluid antigen seems to have reasonable antigenic properties and hence could be employed for epidemiological surveillance of cattle hydatidosis.

Abstract
A cross-sectional study was conducted from December 2008 to March 2009 to assess the status of cystic hydatidosis in cattle slaughtered at Hawassa Municipal abattoir. Out of the total 632 cattle examined visually and manually (palpation and incision), 333 (52.69%) were found harboring hydatid cysts. A significantly higher infection was detected in older cattle (P < 0.05, chi(2) = 4.36) than young. Regarding body condition score, no significant variation (P > 0.05, chi(2) = 2.148) was observed as the prevalence was 54.55% for lean cattle followed by medium (53.83%) and fat (46.88%). Of the total 333 infected, 123 (36.9%) had hydatid cysts only in the lung, 23 (6.9%) in the liver, 12 (3.6%) in the spleen, five (1.5%) in the heart, and three (0.9%) in the kidney while the rest 167 (50.2%) had multiple organ infections. Of the 530 viscera harboring hydatid cysts, the highest (52.83%) was lung followed by liver (34.15%), spleen (9.06%), heart (3.39%), and kidney (0.56%). Size assessment made on 874 cysts indicated that 308 (35.3%) were small, 251 (28.7%) medium, 89 (10.2%) large, and 226 (25.9%) were calcified. The distribution of characterized cysts in different organs based on their size was found to be statistically significant (P < 0.05). In addition, out of the total 874 cysts collected, 26.9% were fertile, 47.3% sterile, and 25.9% calcified or purulent cysts. There was a significant difference in fertility of cyst from different organs (P < 0.05, chi(2) = 27.96), those of lung origin being highly fertile. Likewise, out of the 121 fertile cysts subjected for viability test, 68 (56.2%) were viable. Considering the current result, the total annual economic loss from organ condemnation and carcass weight loss due to bovine hydatidosis at Hawassa Municipal abattoir was estimated at 1,791,625.89 Ethiopian Birr (ETB; 1USD = 12.93ETB). Results in the study were discussed in light of the situation in different parts of Ethiopia and abroad, and finally, relevant recommendations were forwarded.
