The study was carried out from July 2007 to June 2008 in Wolaita Sodo Abattoir to assess the status of hydatidosis in cattle. Routine meat inspection, hydatid cyst count and characterization were conducted. Out of 400 cattle slaughtered in Wolaita Sodo Abattoir 64 (16%) animals were found harboring hydatid cysts. Thorough meat inspection in the abattoir revealed that 74 visceral organ were found harboring one or more hydatid cysts. The infection of the lung, liver, spleen and kidney were found to be 45.94% 45.94%, 6.75% and 1.35% respectively. From the total of 283 hydatid cysts counted 153(54.06%), 17(6.00%), 5(1.76%), 108(38.16%) were found to be small, medium, large and calcified cysts respectively and 170(60.28%), 5(1.76%) and 108(38.16%) were sterile, fertile and calcified cysts respectively. The rate of cyst calcification was higher in the liver than in the lung while fertility rate was higher among the cysts of the lung. Hydatid cyst viability rate of 40% was observed.

A study on the occurrence of coccidiosis and distribution of Eimeria species in dead chickens 1-60 days of age, at Kombolcha Poultry Multiplication and Research Center (KPMRC), Ethiopia was conducted from November 2002 to April 2003. Out of the 965 dead birds, 370 (38.34%) were found to have clinical coccidiosis. The Eimeria species identified in this study were Eimeria brunetti, E. tenella, E. acervulina and E. necatrix with prevalence rates of 45.3%, 40.8%, 9.7%, and 4.1%, respectively. In the current study, E. brunetti was reported for the first time in Ethiopia. It was noted that clinical coccidioisis was more prevalent in those between 5 and 6 weeks of age. A statistically significant difference (p < 0.05) was observed in clinical coccidiosis prevalence among the different age groups studied. Various managerial problems that are associated with this high prevalence of clinical coccidiosis are identified and appropriate control strategies are recommended.

A cross-sectional survey of bovine hydatidosis was carried out on local zebu cattle slaughtered at Birre-Sheleko and Dangila Abattoirs from August 2007 to July 2008 to determine the prevalence and to estimate financial loss caused by the disease. Postmortem examination, hydatid cyst characterization and direct and indirect financial loss estimations were conducted. Out of the total of 521 animals examined (255 Birre-Sheleko and 266 Dangila), 79 (15.2%) were found harbouring one or more hydatid cyst. The prevalence of the disease between the two abattoirs was not significantly different (P > 0.05). The result obtained from postmortem examination indicated that a total of 112 visceral organs were found harbouring one or more hydatid cysts. The involvement of lung, liver, spleen and kidney was found to be 70.5%, 21.4%, 6.3% and 1.8% respectively. From the total of 224 cysts counted, 147 (65.6%), 29 (12.9%), 3 (1.3%) and 45 (20.1%) were small, medium, large and calcified cysts respectively, and 114 (50.9%) and 65 (29%) were sterile and fertile cysts respectively. Viability rate of 47.7%, all from the lungs, and higher liver calcification rate were observed. The annual financial loss from organ condemnation and carcass weight loss due to bovine hydatidosis at Birre-Sheleko and Dangila abattoirs were estimated to be $18911.6.
