Abstract

The study was conducted with the objectives of determining the prevalence, identifying the species involved and assessing possible risk factors of lungworm infection in small ruminant slaughtered in abattoir of Mashhad in the northeast of Iran from October 2010 -August2011. Faecal and postmortem examination were conducted on 350 and 2500 animals, respectively. The overall prevalence of lungworm infection was 10.85% and 3.8% in coproscopic and post mortem examination respectively, and this difference was found to be significant. Higher prevalence of lungworm infection was recorded in post mortem examination in sheep (4.1%) than goats (0.5%) (p < 0.05). The proportion of infection with Dictyocaulus filaria, Protostrongylus rufescens and mixed infection were 3.7%, 0.1% and 0.2% in sheep while in goats, the infection was reported with D.filaria (0.5%) only. The seasonal dynamics of lungworm infection showed that prevalence was highest in winter (7.8%) with a remarkable decline during the dry time (summer) (0.8%) which the difference was significant (p < 0.001).The animals of less than one year showed greater infection in post mortem examination than older animals significantly (p< 0.001).Also, the infection rate between male and female animals showed significant difference (p < 0.05) with prevalence rate of 4.6% and 2%, respectively. Due to its impact on production, emphasis should be given for the control and prevention of lungworm infection in this area.
