Survey on prevalence rate of Linguatula Serrata infection in sheep and goat from sanandaj
Linguatulosis is an important parasitic disease in most parts of the world with majorcause of eliminates the liver in the slaughterhouses. In addition to indirect economicallyloss after infection of Linguatulosis, it affects ruminant productions as well. The adultform of Linguatula Serrata resides within the nasal and respiratory passages of dogs andother canines. It is tongue shaped, lightly convex dorsally and flattened ventrally. Eggsare approximately 70-90 microns. Ruminants such as cattle, sheep, goat and camel asintermediate hosts infect by ingestion of the eggs, and then eggs hatch and larval stagescontinue to develop in visceral cavity and internal organs especially intestinal lymphnodes, liver, lung, spleen and kidneys. After some moulting stages which is around 5-6months, the infective nymph is developed. The aim of the present investigation was toidentify the infection status of slaughtered small ruminants (sheep and goat) to LinguatulaSerata in the Sanandaj slaughterhouse. For this purpose, sampling was done from 70carcasses (35 sheep and 35 goats) in each season and in different seasons. Samples were tested by direct observation and digestive method. In each sampling case location, gender and age of the animal was registered. In this study, none of the investigated samples were infected. Undoubtedly, this situation could be a result of infections absent in carnivores as main host and in priority, dogs in the investigated region. Furthermore, complementary studies should be done for this range of the host.
