The parasite<br />species are the most common pathogens that have severe effects<br />on fish. OBJECTIVES: The aim of the present study is to<br />determine the occurrence and distribution of the plerocercoid of<br />Diphyllobothriidae in two freshwater fish from north and<br />northwest of Iran. Finally, we discuss the role and dynamics of<br />these species of fish in the transmission of infection. METHODS:<br />This study was carried out from September 2011 to September<br />2012on a total of 883 A. bipunctatus and 418 A. brama from north<br />and northwest of Iran. The samples were analyzed to find the<br />plerocercoid infection. RESULTS: From a total number of 883 A.<br />bipunctatus and 418 A. brama fish samples, 558 fish (63.19%)<br />of the former and 67 fish (16.02%) of the latter were infected. The<br />rate of infection was significantly lower in winter (p<0.01). Also,<br />the weight of infected fish was significantly lower than noninfected<br />ones (p<0.01). Moreover, the infection in northwest of<br />Iran was significantly higher than north of Iran (p<0.01).<br />CONCLUSIONS: The family of Diphyllobothriidae is an important<br />cestode and the prevention programs to break the cycle<br />of infection are essential. More suitable solutions to tackle the<br />problem, further epidemiological studies on other fresh water<br />sources of Iran are needed. https://ijvm.ut.ac.ir/article_35060_2c09e1c27aeab9e4cee62fdc9f8e91e5.pdf
