A comparative study of parasitic fauna in Amietophrynus regularis (Reuss, 1833) from natural habitats and dumpsites within Lagos Metropolis, Southwest Nigeria

Abstract Background Amphibian parasites have been used as models for understanding important issues about host activity and sensitivity to environmental perturbations amphibian decline. With the aim of comparing parasitic fauna in Amietophrynus regularis from natural habitat dumpsites within Lagos metropolis, a total 172 toads were sampled determine occurrence gastrointestinal tract blood parasites. Methods The liver, lungs, intestine intestinal fluids, collected parasitological determination. Histopathological analysis was carried out on tracts. Results Helminths recovered belonged family Nematoda, they included Cosmocerca spp ., Amplicaecum . , Strongyloides spp., oxyurides. most abundant with parasite load 2304 prevalence 70.93%. Protozoans fluids include Opalina spp. (7.5%) Balantidium (11.05%). only protozoan species Hepatozoon Although intensity higher larger females, comparison morphometrics not significant at p = 0.05. There also no difference ( 0.05) between abundance location collection. findings revealed stunting villi high level tissue alterations infected habitat. Conclusions levels infection together histopathological are indicative that habitats being perturbed this is concern considering prevailing
