A Histopathology Study of Caspian Seal (Pusa caspica) (Phocidae, Mammalia) Liver Infected with Trematode, Pseudamphistomum truncatum (Rudolphi, 1819) (Opisthorchidae, Trematoda)
BACKGROUND Main objective of this study was to investigate the invasive activity of the liver fluke, Pseudamphistomom truncatum against the Caspian seal (Pusa caspica) and was exemplified at the gross, light microscopy (LM) and electron microscopy (EM) levels. METHODS The study was done on a freshly dead Caspian Seal in the southern coast of Caspian Sea. The checked Caspian seal probably bein...
متن کاملThe Role of Canine Distemper Virus and Persistent Organic Pollutants in Mortality Patterns of Caspian Seals (Pusa caspica)
Persistent organic pollutants are a concern for species occupying high trophic levels since they can cause immunosuppression and impair reproduction. Mass mortalities due to canine distemper virus (CDV) occurred in Caspian seals (Pusa caspica), in spring of 1997, 2000 and 2001, but the potential role of organochlorine exposure in these epizootics remains undetermined. Here we integrate Caspian ...
متن کاملPup production and breeding distribution of the Caspian seal (Phoca caspica) in relation to human impacts.
Aerial surveys of Caspian seals on the winter ice field in Kazakhstan territorial waters were carried out in February 2005 and 2006 to assess the annual pup production for the species and natural predation on newborn pups. Estimated pup production was 21063 in 2005 and 16905 in 2006 (including an estimated figure for pups born in Russian territory in each year). The breeding population size of ...
