The Prevalence of Liver Trematodes in Slaughtered Ruminants in Aydın Province

Abstract

Fasciola hepatica and Dicrocoelium dendriticum are widely found worldwide including in Turkey. Liver trematode infections cause serious losses in livestock production. Also, it adversely affects the development and live weight gain of animals and damage the national economy by causing the loss of economical significant organs such as the liver. This study was performed to investigate the reveal the prevalence of Fasciola and Dicrocoelium parasites at the slaughterhouse in Aydın province and to investigate the resulting economic losses. This study was carried out in a slaughterhouse in Aydın. Sampling was done between May 2015- June 2016. According to this, liver and bile ducts of slaughtered sheep-goat and cattle have been examined in terms of Fasciola spp. and Dicrocoelium spp. for a year. During the study a total of 3193 cattle and 3659 small ruminant (sheep and goat) livers were examined. Two species of liver fluke, Fasciola hepatica and Dicrocoelium dendriticum, were encountered in this study. Fasciola hepatica was detected in six of 3193 cattle (%0,18) and in one of 3659 (%0,02) small ruminants. In addition, Dicrocoelium dendriticum was detected in 13 of 3659 (%0,3) small ruminants. F. gigantica and D. dendriticum were not found in cattle livers that were examined. The data in this study give valuable information concerning the prevalence of F. hepatica and D. dendriticum in slaughtered cattle and sheep in Aydın. To our knowledge, this study is the first study about the examination of liver flukes in an abattoir in Aydın. Even if it seems that the fluke infection rates of slaughtered animals in Aydın are not important at present, the impact of economic losses arising due to liver destruction on the country should not be neglected.
