Abstract

Linguatula serrata is a cosmopolitan zoonotic parasite. Infective nymphs of the parasite localize in mesenteric Lymph nodes of herbivorous intermediate hosts. Humans can be occasionally infected with both adult and nymphal stages of the parasite. This cross-sectional study was conducted to determine the frequency of linguatulosis in Goats slaughtered in Lorestan province and evaluate the pathological lesions caused by L. serrata nymphs in mesenteric Lymph nodes. Mesenteric Lymph nodes of 240 Goats were collected randomly from three different slaughterhouses of Lorestan province during a one-year period. Lymph nodes were examined grossly and submitted for parasitological and pathological studies. Furthermore, an acid-pepsin digestion method was applied for investigation of negative samples. One hundred and twenty-seven out of 240 Goats (52. 91 %) were infected with L. serrata nymphs. The frequency of infection increased in summer and was highly significant (P<0. 01), while the intensity of infection was not significantly associated with seasons. Histopathologic examination revealed the nymph of L. serrata, with segmented body and cuticle with transversely striated spines. In most microscopic sections, Lymph nodes were depleted from lymphocytes and numerous necrotic areas, edema and hemorrhage, hemosiderin formation and hemosiderophages were significant. High frequency of infection in Goats suggests possibility of infection in humans inhabit these regions. Avoiding consumption of raw visceral organs of Goats by dogs can help reduce the infection in humans and intermediate hosts.
