A slaughterhouse study on prevalence of some helminths of cattle in Lorestan provience, west Iran

ObjectiveTo investigate and provide data on the prevalence, epidemiological pattern zoonotic impact of helminth parasites in cattle slaughtered at abattoir in Khorramabad, Lorestan province, southwestern Iran from April 2010 to April 2013.MethodsA total of 150869 livers of cattle were examined. The total prevalence rate of distomatosis and hydaditidosis in different seasons were calculated.ResutlsThe overall prevalence rate of infection was 23.3%. The prevalence rate of hydatid cyst (9.4%) infection was significantly higher than the prevalence of fasciolosis (7.6%) and dicrocoeliosis (6.3%) (P<0.001). Data showed significant seasonal pattern for three parasitic infections (P<0.001). The highest prevalence rate of Fasciola spp. and D. dendriticum infection were seen in spring, while the highest rate of hydatidosis was seen in winter. The highest and lowest of overall infection were recorded during winter 2012 and autumn 2011, respectively.ConclusionsAccording to this study, it can be concluded that Khorramabad as an endemic region for distomatosis and hydatidosis infection. More surveys are suggested to be carried out to collect more data about the internal organs infection prevalence and risk factors for developing a prediction model in ruminants in southwestern Iran.
