Objective: Fasciola infestation in breeding animals and studying
of effective factors in parasite epidemiology in kermanshah.
Project: Field - laboratory study. Procedure: To study fasciolosis epidemiology in Kermanshah
province, the following factors were studied: A- Climatic conditions:
Climatic indices such as average raining, average monthly and
annual temperature and humidity were obtained from Iranian Meteorological Organization. Based on meteorological data, this province, microclimatically, is divided into 1) warm plains (Gilan- e-Gharb, Sar-e-Pol-e-Zahab,...), 2) temperate plains (Kangavar,
Sahneh and Songhor), 3) mountainous (Kermanshah and Islam
Abad) and 4) cold mountainous (Uramanat). B-Existence of intermediate hosts snails: sampling was done on some of the province water sources at least once a season. Identification of intermediate host snails was done based on their specifications. C-Infestation
conditions in breeding animals (sheep, goats and cattle):
stool samples were taken randomly and examined by flotation
method. D- Infestation conditions in slaughterhouses: Infestation situation of the animals, slaughtered in the province, to fasciola, was examined within a year.
Results: On sampling from different ponds in the province Lymnea
truncatula (intermediate host of Fasciola hepatica) and L. gedrosiana
and L.auricularia (intermediate host of Fasiola gicantica) were found. But the prevalence of intermediated host is different in
various regions. Random sampling was done in breeding sheep, goats and cattle. Areas I and II were the most infested and area
IV was the least one. Based on the slaughterhouse datas, the highest
and lowest rate of infestation were seen in area 1 and Paveh and Javanrood (area 4), respectively. Conclusion: Due to the difference of the provice height and
microclimatological datas, infestation rate to fasciola is defferent
in various regions. Area 1 and 2 are appropriate zones for fascioliosis to occur and area 4 is an inappropriate zone. J. Fac. Vet. Med. Univ. Tehran. 59, 3: 201-206, 2004.
