Information is very scarce on the prevalence of hepatitis-B virus (HBV) infection among blood donors and patients with human immunodeficiency virus (HIV) infection in Nigeria. Hepatitis-B surface antigen (HBsAg) ELISA was used to determined the prevalence of HBsAg among 175 blood donors (aged 20-40 years) and 490 HIV-infected patients (aged 17-60 years) in(More)
The carriage rate of Hepatitis-B surface antigen (HBsAg) in an urban community in Jos, the Plateau State capital, was studied to obtain the pattern of Hepatitis-beta virus (HBV) spread within the community. HBsAg screening was performed on a consecutive sample of 524 apparently healthy individuals (293 males and 231 females) aged 15-65 years who voluntarily(More)
The enzyme-linked immunosorbent assay (Elisa) was used to examine sera of 104 children and adults in Jos, Plateau State, Nigeria for anti-toxocaral antibodies, out of which 31 (29.8%) were reactive. The seropositive rates were 30.4% for adults, 29.6% for children, 34% for females and 25.9% for males. However, the differences were not significant by age and(More)
Schistosoma mansoni infection constitutes significant economic and public health consequences. Accurate diagnosis of the infection is imperative in order to identify subjects needing care in the broadest sense. In this study the dot-ELISA and direct parasitological method were compared in the diagnosis of S. mansoni infection in Jos, Nigeria. Of the 106(More)
Toxoplasma gondii infection has become a major public health concern in recent times due to the ravaging HIV/AIDS pandemic. The seroprevalence of T. gondii infection was determined in Kwal, a rural district of Plateau-Nigeria using IgG-ELISA. Epidemiological assessment was also conducted for the purpose of establishing the infection dynamics. Antibodies to(More)
This study was undertaken to establish local CD4+LC standards, which could be used as indicators of immune deficiency or monitor progress of HIV therapy, instead of relying on Caucasian standards, which may not exactly reflect Nigerian CD4+LC sub-populations. CD4+LC from 1232 Nigerian adults were studied. They included 852 apparently healthy individuals,(More)
Toxoplasma gondii IgG antibody seroprevalence was studied in two different populations of 219 HIV-infected patients and 144 apparently healthy individuals (AHIs). Clinical toxoplasmosis was assessed among the HIV-infected patients. Antibodies to T. gondii were detected in 85 (38.8%, 95% CI: 32.36%-45.26%) of the HIV-infected patients and in 30 (20.8%, 95%(More)
We conducted a national molecular epidemiologic survey of HIV-1 strains in Nigeria to determine the most prevalent subtype(s) for use in developing candidate vaccines. A total of 230 HIV-1-positive blood samples collected from 34 of the 36 Nigerian states were analyzed by our modified env gp41-based heteroduplex mobility assay (HMA) and/or gp41 sequencing(More)
