| effect of ascorbic acid on the immune response of the catfish, mystus gulio (hamilton), to different bacterins of aeromonas hydrophila. | ascorbic acid is one of the essential vitamins for normal physiological activities of any organism. the present study demonstrates an immunostimulatory effect of vitamin c on the humoral and cell mediated immunity of the bagrid catfish, mystus gulio, determined using different bacterins of aeromonas hydrophila. humoral as well as cell mediated immune responses were elucidated in the vitamin supplemented, vaccinated and unvaccinated groups. the vitamin supplemented lipopolysaccharide (lps) vaccin ... | 2001 | 11417721 |
| first record of cymothoa indica (crustacea, isopoda, cymothoidae) infecting the cultured catfish mystus gulio in india. | cymothoa indica (isopoda, cymothoidae) is reported parasitizing the long-whiskered catfish mystus gulio, cultured in an experimental cage in india. the specimens observed were adult males and females, which had mainly settled in the buccal cavity of juvenile catfish. the species was previously known from wild populations of siganidae and belonidae, but this is the first record of c. indica parasitizing the cultured long-whiskered catfish. serious lesions, typical of a crustacean infection, were ... | 2005 | 16119896 |
| the immune response in catfish, mystus gulio. | light microscopic studies of the immune response of mystus gulio were carried out. antigen binding cells have been detected by plaque-forming cell (pfc) assay test in the spleen, head-kidney (hk) and thymus. among these three organs, the hk is more pronounced in its response, and it is compared, on the basis of its histology of higher vertebrates. the peak response after primary and secondary immunizations was on day 7, in both circulating blood and the immune organs. the results suggest that hk ... | 2008 | 19297981 |
| studies on trichodinid and chilodonellid ciliophorans (protozoa: ciliophora) in the indian freshwater and estuarine fishes with description of trichodinella sunderbanensis sp. nov. and trichodina nandusi sp. nov. | a comprehensive icthyoparasotological survey among estuarine and freshwater fishes of west bengal, india revealed trichodinella sunderbanensis sp. nov. and trichodina acuta lom, 1961 from an estuarine fish mystus gulio (hamilton, 1822) from the vidyadhari river; trichodina nandusi sp. nov. from a freshwater fish, nandus nandus (hamilton-buchanan); chilodonella hexasticha (kiernik, 1909) kahl, 1931 from freshwater fishes labeo rohita (hamilton, 1822); and cyprinus carpio linnaeus, 1758 from the r ... | 2012 | 23269510 |
| methyl mercury in fish-a case study on various samples collected from ganges river at west bengal. | this study investigated the presence of total mercury (hg) and organic mercury levels in the muscle of 19 common fresh water fish species captured from river ganges, west bengal, india. the total mercury level found in our study may not cause any toxic effect, but the methyl mercury (mehg) level in some freshwater fish species was surprisingly very high and toxically unacceptable. the results of mercury analysis in various specimens indicated that some fish muscles tended to accumulate high leve ... | 2011 | 21713467 |
