A total of 200 animals were randomly selected from five different peasant associations in the study area and examined during the study period. Coprological examination for the detection of strongyle eggs was performed using floatation technique. The overall prevalence of strongyle parasites was 30.5% (61 from 200 donkeys). The study has also showed variation in prevalence of strongyle parasites among different body condition scores and between ages, higher prevalence was recorded in poor body condition (83.72%) and old (46.15%), respectively. In relation to selected peasant association the prevalence were found 38.88%, 32%, 23.52%, 17.64% and 30%, for Assoa 01, Assosa 03, Amba 4, Amba 5 and Amba 8, respectively. The risk factors, age and body condition, were significantly...

Three hundred seventy eight (378) fecal samples were collected from dairy cattle and examined for the presence of the oocysts of Eimeria by floatation technique using concentrated sucrose solution and for that of oocysts of Cryptosporidium employing Modified Ziehl Nelseen Acid fast staining technique. The study revealed that the overall prevalence of eimeriosis and cryptospordiosis was 51.9%. However, the prevalence of Eimeria and Cryptosporidium was found to be 47.1% and 10.8%, respectively. In this study age, sex, production system, body condition and fecal consistency were considered as risk factors. There was a statically significant difference (P<0.05) in the overall prevalence of Eimeria and Cryp...

This is due to a number of factors and driving forces that have a potential to create a new era of emerging and re-emerging zoonotic diseases. These factors are complicated and the complex nature of the human animal interface is constantly influenced by the effects of climate change, anthropogenic and natural factors. Change in ecosystem, microbial adaptation, climate and weather change, Lack of adequate food safety, international travel and commerce, animal migration, increased human-animal interface, human demographic and behavioral factors, technology and industry, bush meat hunting, and keeping pets are among the most common factors that contribute for the occurrence of emerging and re-emerging zoonotic diseases. Microbial evolution is the intrinsic factor that leads to the emergence of new pathogens, while social and environme...

A cross sectional study was conducted in and around Dessie from November 2017 to April 2018 to determine the prevalence of skin diseases in cattle and their associated risk factors. Animals were examined for the presence of any skin disease through visual inspection and palpation and from those showing clinical signs and tentatively diagnosed for the presence of skin disease appropriate samples were taken for laboratory examination. Out of 460 cattle examined, 71 (15.4%) were affected by skin diseases. There were statistically significant variations among the different age groups and origins in prevalence of skin diseases. Young animals were more affected by skin diseases than old and adult 19.4%, 14.4% and 13.7%, respectively. There was no statistically significant difference in the prevalence of skin diseases between sex, breed, body condition score and management syste...

The aim of this study was to identify and determine major causes of poultry carcass condemnation and to estimate the direct financial losses attributed to the condemned carcass. During the study period broilers were selected by systematic random sampling using regular interval to quantify the rate and reason of condemnation. Out of 850 broilers slaughtered, 25 (2.9%) carcass was rejected. The overall average of bruising was (0.82%) per total slaughtered broilers. The other causes of condemnation were cachexia, dead on arrival, poor bleeding, cellulitis, over scalding, septicemia, fracture and contamination. From these bruising is the most frequent reason for poultry carcass condemnation in this study. During the study standard inspection procedures were followed and daily condemnation records were used as the sources of data. T...

A total of 214 milk and swab samples were collected for laboratory detection of Escherichia coli O157:H7. Samples were cultured in selective media to detect the presence of non-sorbitol fermenting (NSF) Escherichia coli. Biochemical and serological tests were employed to confirm E. coli O157:H7 strain. The overall isolation rate of E. coli and E. coli O157:H7 were found to be 46.26% and 4.2%, respectively. The highest prevalence was recorded in samples obtained from cafeterias (11.76%) compared with samples from farms (2.78%) and milk collection centers (2.63%). There was statistically significant difference (p<0.05) of E. coli O157:H7 between sample sources, sample ty...
