"Oxidative Stress Markers in Parasitized\r\nand Non-Parasitized Amietophrynus\r\nregularis (Reuss, 1833) Exposed to Multi-\r\nStress Conditions in Lagos Metropolis,\r\nNigeria"^^ . "Background: Amphibians are subjected to a variety of natural and artificial\r\nstresses that can compromise physiological balance. This study explored\r\nthe variations in oxidative stress markers in Cosmocercan parasitized and\r\nnon-parasitized Amietophrynus regularis in diverse conditions. The toad\r\nspecimens were collected from natural habitats and dumpsites of three (3)\r\nmajor areas of Lagos. 15 g wet weight of the liver, intestine, and parasites\r\nwere separately prepared and analyzed for oxidative stress parameters\r\nincluding; SOD, CAT, GSH, and MDA activities according to well-established\r\nprotocols. Result: Based on stations, there were significant differences in the\r\nSOD levels in the liver and intestine of infected and uninfected toads\r\nobtained at the dumpsite and the natural habitat at p < 0.001. Also, the\r\nconcentration of SOD in the parasites (238.86 ± 7.72 min/mg prot.)\r\nrecovered from the toads at the dumpsite was very much significantly\r\nhigher than the concentration in those recovered from the toads in the\r\nnatural habitat (p < 0.001). The study has shown that the level of SOD released by the antioxidant defense system in response to the oxidative\r\nstress in the organism makes it a reliable tool for ecotoxicological\r\nassessment. All the oxidative stress markers except for MDA showed\r\nsignificant differences at p < 0.05 between the host tissues and the\r\nparasites irrespective of sampling locations indicating both organisms were\r\nstressed either due to the host-parasite relationship or from other\r\nenvironmental contaminants. Conclusions: The toad’s antioxidant defense\r\nsystem was typically sensitive and adaptable to environmental conditions,\r\nsuggesting that it could be used in future research on effective\r\necotoxicological evaluation tools."^^ .
