| Popis: | Objective To analyse the prevalence and pathology of lymphocystis disease in Sardinella longiceps of three different landing centers in Tamil Nadu of southeast coast of India for a period of three years from January 2013 to December 2015. Methods Tumourous sardines were sourced from three different landing centers (Cuddalore, Parangipettai and Nagapattinam) in Tamil Nadu, southeast coast of India. The prevalence of lymphocystis, and its gross pathology, histopathology were investigated. Results A total of 369 individuals were affected with lymphocystis. The overall prevalence was 0.11% among the three stations. The uncircumscribed, translucent white, pink and reddish and jelly-like nodules of cell growths scattered on the both sides of eyes and operculum plates. Histopathological studies of the white masses showed abundant hypertrophied cells with cytoplasmic vacuoles and basophilic intra-cytoplasmic inclusion bodies. The hypertrophied cells had pleomorphic, hypertropic and hyperchromatic nuclei and contained basophilic marginated chromatin. Conclusions The histological and ultra-structural findings, the lesions were diagnosed as the hypertrophied cells. The lesions were confirmed the lymphocystis disease in Sardinella longiceps. |
