Investigation of parasitic and bacterial diseases in pigs with analysis of hematological and serum biochemical profile

The present study was undertaken to evaluate various disease conditions prevalent in slaughtered pigs and zoonotic importance. The study was conducted on two hundred non-descript pigs slaughtered at an organized slaughter house, Mumbai. The animals included in the study were randomly selected. Post mortem examination of the animals was performed to note various disease conditions and tissues were collected for histopathology. Direct examination of stool was found negative for parasites. Gross and microscopical examination revealed presence of Ascarops strongylina, Sarcocyst, Hydatid cyst, Cysticercus cellulosae, Ascaris suum and Cysticercus tenuicollis, along with bacteria like Salmonella, Pseudomonas, Shigella, Streptococci, Proteus and Pasteurella spp. were isolated. Indirect ELISA was performed for detection of antibody titer in the pig serum against classical swine fever. Studies on hematological and serum biochemical profile revealed decreased total protein concentration and globulin level with leukocytosis and neutrophilia and in parasitic infections eosinophilia was evident.
