Prevalence of Linguatula Serrata Infection in Domestic Ruminants in West Part of Iran: Risk Factors and Public Health Implications

Linguatulosis is one of the neglected parasitic zoonoses. Domestic ruminants are the important source for human infection. The main goal of the present investigation was to evaluate the prevalence of nymphal stages of L. serrata in domestic ruminant in Hamedan province, western Iran. The mesenteric and mediastinal lymph node of 1080 animals were taken randomly from different slaughterhouses of Hamedan province. All lymph nodes were examined for nymphal stage of L. serrata using parasitological methods (digestion technique). The nymph of L. serrata was found in 31.4% (69/220) of goats, 15% (60/400) of sheep, and 7.4% (34/460) of cattle (P=0.457). The infection rate in beef cattle, dairy cattle and native cattle was 1.3%, 6.4% and 12.6%, respectively (P=0.981). No evidence of correlation between gender, age groups, and L. serrata infection rate in sheep and cattle (P>0.05). In goats, the infection rate in >2yr old (48%) was higher than
