Affinity purification and partial characterization of IgM-like immunoglobulins of African catfish, Clarias gariepinus (Burchell, 1822).
IgM like macroglobulin from bovine serum albumin (BSA)-immunized African catfish C. gariepinus was purified by affinity chromatography and partially characterized. The molecular weight of this macroglobulin was 840 kDa, as estimated by gel filtration chromatography. Purified macroglobulin was analyzed using SDS-PAGE under reducing and non-reducing conditions. The molecular weight (MW) of heavy ...
متن کامل"Toxic effects of 4-nonylphenol on the embryonic development of African catfish Clarias gariepinus (Burchell, 1822) ''
The present study investigated effects of environmental relevant concentrations of 4-nonylphenol (0.05 to 0.08 to 0.1 mg/l) on the reproduction and embryonic developmental stages of catfish (Clarias gariepinus). To determine the effect of 4-nonylphenol on reproduction; catfish were exposed to three concentrations of 4-nonylphenol in a flow-through-system during spawning period (some for one wee...
متن کاملParasites of South African freshwater fish. I. Some nematodes of the catfish [Clarias gariepinus (Burchell, 1822)] from the Hartbeespoort Dam.
A seasonal study of the parasites of fish in the Hartbeespoort Dam was undertaken in 1979. This paper deals with 4 nematode species recovered from catfish, namely, Paracamallanus cyathopharynx (Baylis, 1923), Procamallanus laeviconchus (Wedl, 1862), Contracaecum sp. and Skrjabinocara sp. Total numbers of parasites recovered are tabulated and their seasonal variation illustrated diagrammatically...
متن کاملEnvironmental monitoring and health risk assessment of African catfish Clarias gariepinus (Burchell, 1822) cultured in rural ponds, India.
Water quality monitoring of Clarias gariepinus culture ponds (n = 27) revealed poor physico-chemical conditions and metal contaminants in fish tissues (n = 324). Human health risk assessment for some heavy metal contamination delineated low risk in general except for Aluminium (Al), Iron (Fe) and Lead (Pb) which accumulated significantly (p < 0.05) high in tissues. Health risks values were 6.3 ...
متن کاملChanges in behavior and hematological parameters of freshwater African catfish Clarias gariepinus (Burchell 1822) following sublethal exposure to chloramphenicol.
The present study was aimed at evaluating the effects of different concentrations of the most commonly used fish antimicrobial drug, chloramphenicol (CAP), on the behavior and hematological parameters of Clarias gariepinus. Fish specimens were exposed to three (2.5, 5.0 and 10.0 mg L(-1)) sublethal concentrations of CAP and a control. Abnormal behavioral changes were observed in fish exposed to...
