ABSTRACT

A cross-sectional study was conducted from October 2015 to April 2016 to estimate the prevalence of lungworm infection and to assess some of the determinant risk factors associated with ovine lungworm infections in and around Ambo, Central Ethiopia. Fecal samples were collected from randomly selected 349 sheep, kept under extensive management systems, to examine first-stage larvae (L1) using Baermann technique. Additionally, samples were collected from 44 sheep slaughtered in different restaurants and hotels to examine the presence of adult lungworm parasites. The overall prevalence recorded from fecal and postmortem examinations was 23.2% and 31.8%, respectively. A higher prevalence was observed in females (26.2%) than in males (17.7%). Age-wise, a higher prevalence (29.1%) was observed in animals greater than 6 months to 2 years old, while the lowest (13.5%) was observed in animals less than or equal to 6 months. However, the prevalence noted, both in line with age and sex categories, was not statistically significant (P > 0.05). On the other hand, a higher prevalence was observed in sheep with poor body condition (37.6%), followed by moderate (21.9%) and good (12.4%) body-conditioned animals, and the difference was statistically significant (p<0.05). Similarly, the prevalence of lungworm infection in apparently healthy groups was 17.0%, while that of the sick was 52.5% and the difference was significant statistically (p<0.05). The prevalence of lungworm infection during postmortem examination of slaughtered sheep was higher (31.8%) than the result obtained at coprology (23.2%). The present study confirmed that lungworm infection was a common problem among sheep in the study area. Due to its impact on production, emphasis should be given to the control and prevention of lungworm infection in the study area, like the application of repeated deworming and grazing management.
