Abstract

    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 ≤2yr old (8.6%) (P<0.0001,
OR=5.6); also the infection rate was 23.7% and 35.7% in male and female goats,
respectively (P=0.065). This is the first report of linguatulosis in
domestic animals from western Iran. The results indicate that linguatulosis may
partly be responsible for economic losses in domestic ruminant husbandry in
this region. Therefore, designing control strategies for a better management in
animals farm to reduce the risk of zoonotic outbreaks is highly recommended.
