ArticleItem Open Access Concurrent Marek's Disease and Cestodiasis in a Blue Rock Pigeon (Columbia Livia)(Indian Veterinary Journal, 2015-05) Ramesh, S.; Balachandran, C.; Vijayarani, K.; Latha, B.R.; Kavitha, K.T.; Palanivelrajan, M.; Senthilkumar, K.; Savithri, M.; Pazhanivel, N.; Jayathangaraj, M.G.; TANUVASA Blue Rock pigeon (Columbia livia) found dead in Chennai revealed congestion of the serosal surface of the entire digestive tract and haemorrhages in the mucosal surface with tape worm segments, identified as Cotugnia sp in the lumen of the intestine. Histopathological examination of the liver and kidney as well as PCR confirmed Marek's disease.ArticleItem Open Access Marek's Disease in an Amazon Parrot (Amazona sp.)(Indian Veterinary Journal, 2015-05) Ramesh, S.; Balachandran, C.; Ramamurthy, N.; Vijayarani, K.; Srinivasan, G.; Senthilkumar, K.; Palanivelrajan, M; Savithri, M.; Jayathangaraj, M.G.; TANUVASThe carcass of a male Amazon parrot (Amazona sp) revealed marked enlargement of liver and congestion in the mucosal surface of the entire digestive tract. Histopathological examination of liver revealed infiltration of heterogenous population of lymphoid cells. Hepatocytes revealed vacuolar degeneration and fatty cysts. Hepatocytes were also arranged in acinar pattern. PCR carried out using Meq gene primers with liver were confirmative of Marek's disease. Based on these findings, the cause of death was attributed to Marek's disease.ArticleItem Open Access Mycoplasmosis in a Moluccan Cockatoo (Cacatua moluccensis)(2015-04) Ramesh, s; Vijayarani, K.; Ramamurthy, N.; Srinivasan, G.; Senthilkumar, K.; Palanivelrajan, M.; Savithri, M.; Jayathangaraj, M.G.; TANUVASArticleItem Open Access A Preliminary Study on the Anti Neoplastic Effect of Prodigiosin Produced by Serratia marcescens Isolated from Termite (Odontotermes formosanus)(Indian Journal of Veterinary Pathology, 2013) Vijayarani, K.; Gowralkar, Maheswarappa; Sesh, P.S.L.; Savithri, M.; Kumanan, K.; TANUVASProdigiosin, a natural red pigment produced by a variety of bacteria has been reported to have antibacterial, antifungal, anti malarial and anti neoplastic activity. In this study, prodigiosin produced by Serratia marcescens has been tested for its in vitro anti neoplastic activity. S.marcescens was isolated from termite gut, identified and characterized by morphology, Gram’s staining, biochemical and carbohydrate fermentation tests. S. marcescens produced red to dark pigment on nutrient agar. Prodigiosin produced by S. marcescens was purified by thin layer chromatography. The antineoplastic effect of the pigment was assessed in cancerous cell lines such as HeLa and HEp2 by MTT assay and Comet assay. Cytotoxic properties of prodigiosin pigment was evaluated by using Vero cells.
