Diagnosis of filariasis is important for Programme Managers and Physicians. This study was undertaken to determine the prevalence of lymphatic filariasis in eleven communities of Northern Taraba State. The study employed standard parasitological techniques for diagnosis, and the use of Immunochromatographic Card Test (ICT) to detect Circulating Filarial Antigen (CFA). Chi Square was used to compare and test for differences in infections among communities. 294 persons were examined, and 31.29% were confirmed positive for Wuchereria bancrofti. The performance of ICT card compared with Thick Blood Film microscopy was commendable. Thick Blood Film/microscopy identified 26.19% infection of the population, while the ICT card detected 31.29% CFA from the same population. The prevalence of CFA differ significantly (p < 0.05), and no significant difference between antigenaemia in males and females. However, chi-square test revealed a significant difference in the prevalence of antigenaemia among the different age groups. Antigenaemia was detected in 92 persons, and 34 (36.96%) persons are both antigenaemia positive and microfilaria positive, while 58 persons (63.04%) with antigenaemia but without microfilaraemia. Of the 202 negative subjects 43 (21.29%) had microfilaria in their blood samples, while 159 (78.71%) were negative for microfilaraemia. The ability of the ICT to accurately identify all those with the disease was 44.16%, while the ability of the ICT to sort out those without disease was 73.27%. The Positive Predictive Value was 36.96%, while the Negative predictive value was 78.71% burden of LF. In conclusion, since the ICT had identified 31.29% people with LF as against 26.19% by Microscopy, it was suggested that it could be employed in mass survey for Lymphatic filariasis to institute intervention activities in the area.
House flies (Musca domestica) are nuisance pest because of their ubiquitous nature in the mechanical transmission of parasites to man. This study identifies the pathogenic parasites associated with house fly in Jalingo, Nigeria. A total of 200 flies were collected from 4 locations (Abattoir, Jalingo Main Market, Kasuwan Bera and Mile-Six Market) within Jalingo metropolis between August, 2019 and November, 2019. Three species of flies were identified during the study namely; Musca spp, Sacophage spp and Stomoxys spp. The house flies were analyzed for the presence pathogenic parasites using standard laboratory techniques. The results showed that the parasites E. histolytica 25(28.74 %), Taenia spp 25(28.74 %), A. lumbricoides 20(22.99 %), Giardia lamblia 8(9.20 %) and Trichuris trichiura 9(10.34 %) are associated with the house flies. The results showed no significant variation (X2= 0.61, p>0.05) between the parasites species. It can be concluded that house flies in Jalingo harbor pathogenic parasites on their bodies. The fact that houseflies have been incriminated to be mechanical transmitters of pathogenic diseases to man because of their anthropogenic lifestyles, measures must be taken to control fly population in order to avert both the present and future outbreak of disease conditions emanating from the flies activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
