Cytology is a science of cells that is used to differentiate between normal cells, neoplastic cells and inflamed cells. It has great acceptance than any other diagnostic methods due to its quickness, inexpensiveness and simplicity. It uses the techniques such as fine needle aspiration, impression, scraping, swabs, centesis and catheterization for sample collection. Also slide preparation uses a simple technique such as squash, blood smear; needle spread and line smear techniques. What makes cytology unique is that it can tell us the result of the diseases while the patient is with us. This science has also wide application on determining the external and internal diseases including neoplastic diseases. In case of neoplastic diseases it is important to differentiate between neoplastic nucleus, neoplastic cytoplasm and neoplastic structure of different cells with their normal cells. In addition to these, it also used in direct therapy, to form prognosis and to determinate next diagnostic procedures. Character of the lesion and tissue sampled play pivotal roles in the diagnostic value of cytology. Familiarity with preferred sampling methods and reported accuracy is critical for veterinary practitioners and sample of good quality is imperative. Different specimen sampling methods and specimen processing methods should be properly practiced.

Purpose Newcastle disease causes considerable loss in the poultry industry worldwide and its outbreaks are regularly reported from all continents of the world, including Ethiopia. The investigation was conducted from October 2020 to June 2021 to determine the prevalence of Newcastle disease (ND) in districts selected from Buno Bedele zone, Western Oromia. Methods The study design used was a cross-sectional type. For this study, a total of 480 serum samples were collected as per sample collection guideline from randomly selected chickens that were apparently healthy and had no history of vaccination against Newcastle disease. Indirect ELISA was performed and all data were analyzed using SPSS statistical software. Results From serological investigation, overall seroprevalence of Newcastle disease was 30%. Seroprevalence of Newcastle disease was 34.94%, 22.22%, and 31.76% in Didessa, Chora, and Gachi districts, respectively. Among computed risk factors, breed showed statistically significant difference and the odds of infection were lower in adult than in young chickens. Similarly, the odds of infection with Newcastle disease virus were significantly higher in crossbred than in locally bred backyard chickens. Conclusion This study revealed Newcastle disease was prevalent in the study areas; therefore, regular investigation of Newcastle disease should be conducted along with detailed studies on molecular characterization of circulating field strains in the area.

Purpose: Although helminthiasis have been recognized as health constraints of small ruminants, there was no study conducted to reveal their types and burden in goats and sheep slaughtered at Bishoftu, Ethiopia. Hence, this study is aimed to evaluate the current status of helminth parasites and estimate its burden in study animals. Methods: The study was carried out from November 2016 to April 2017 to identify the species and also to estimate the burden of small intestinal parasitic helminth in goats and sheep using a standard worm recovery procedure. The study animals were 230 goats and sheep slaughtered at Bishoftu Elfora export abattoir during the study period. Results:The study revealed that the overall infection rate was 83.5%. Among 105 samples taken from sheep, 87.6% were positive, whereas 100 (80%) of 125 examined samples from goats were positive for helminth parasites. There was no statistically significant difference (p>0.05) between the species. However, age and animal origin considered as a risk factor indicated statistically significant differences (p<0.05). In sheep, the prevalence of Trichostrongylus colubriformis, Bunostomum trigonocephalum, and Moniezia expansa was 69 (46.9%), 34 (43.6%), and 51 (52.6%), respectively, while the prevalence of Trichostrongylus colubriformis, Bunostomum trigonocephalum, and Moniezia expansa in goats was 78 (53.1%), 44 (56.4%), and 46 (47.4%), respectively. Conclusion:This study revealed a high infection with parasitic helminths. Thus, effective control and prevention methods are necessary to minimize their effects on animals as well as the economy.
