Abstract

This survey was carried out on prevalence rates of Linguatula serrata in small ruminants in Hamedan, Iran during September till March 2011. The mesenteric lymph nodes (MLNs), livers, and lungs of 75 goats (2 females and 73 males) and 225 sheeps (19 females and 206 males) were examined for L. serrata nymphs. Animals were categorized into three age groups, i.e., under 12 months, 12–24 months, and over 2 years. The results showed that 30.6 % of goats and 10.2 % of sheeps were infected with L. serrata nymphs. The infection in females was significantly higher than that of males (p < 0.05). Age had no significant effect on the prevalence of the parasite. The results revealed the urgency of a more thorough investigation of MLNs and lung lymph nodes’ inspection in small ruminants of the region.
