Abstract: (595 Views)
Helminthic parasitic infections in livestock are among the most common health issues causing significant economic losses to the global livestock industry, including in countries such as Iran. The aim of this study was to determine the prevalence of liver and lung parasitic infections in slaughtered cattle at the slaughterhouse of Bavi County. In this descriptive and analytical study, the livers and lungs of 680 slaughtered cattle were macroscopically examined for parasitic infections at the Bavi County slaughterhouse from October to December 2022. Additionally, protoscolices observed in hydatid cysts were evaluated for fertility using 1% eosin staining under a microscope. Fertile protoscolices were distinguished from infertile ones based on their ability to exclude the dye. Of the 680 examined carcasses, 151 (22.06%) were found to be infected with liver and/or lung parasites. Specifically, 123 livers (18.09%) and 41 lungs (6.03%) showed evidence of parasitic infection. The highest infection rate was observed in December (37.08%), while the lowest was in October (28.48%). Examination of liver fluke infections revealed a 2.9% prevalence of Fasciola spp., while no cases of Dicrocoelium dendriticum were detected. Hydatidosis was present in 15.15% of the cattle, with infections affecting the liver (15.15%) and lungs (6.03%). Furthermore, 2.2% of the animals had simultaneous hydatid cysts in both liver and lung tissues. The fertility rates of hydatid cysts were 78.64% in the liver and 26.83% in the lungs. These findings highlight the importance of improving the cultural awareness of livestock breeders, transitioning away from traditional animal husbandry practices, and implementing better livestock management strategies to reduce the prevalence of parasitic infections in cattle
