BACKGROUND Chlamydia infections have been reported to cause silent infections in communities which becomes endemic and could remain unnoticed for a very long time. In most parts of Nigeria these organisms are not screened for, and hence relative information about frequencies of the organisms are sparse. METHOD Five hundred and sixty five blood samples and(More)
Solutions of potassium hydroxide and sodium hydroxide with concentrations between 0.5% and 4% were found to produce mucoid and sticky suspensions when added in drops, using a bacteriological loop, to smears of 609 strains of gram-negative bacteria on glass slides. A total of 461 strains of gram-positive bacteria and yeasts did not produce any mucoid or(More)
Next-generation sequencing (NGS) has the potential to transform the discovery of viruses causing unexplained acute febrile illness (UAFI) because it does not depend on culturing the pathogen or a priori knowledge of the pathogen's nucleic acid sequence. More generally, it has the potential to elucidate the complete human virome, including viruses that cause(More)
Enteropathogenic, enterotoxigenic and enteroinvasive Escherichia coli were isolated from 52 (4.8%) of 1,082 patients with acute gastroenteritis reporting at the Lagos University Teaching Hospital, Lagos, Nigeria between October 1979 and March, 1981. Of the 52 strains of E. coli isolated, 35 (67.3%) were enteropathogenic, 12 (23.1%) were enterotoxigenic and(More)
Five Yersinia strains, biochemically mimicking Yersinia intermedia, were isolated from patients with acute diarrheal diseases seen at the University of Lagos (Nigeria) Teaching Hospital between October 1979 and September 1982. The five isolates utilized citrate as their source of carbon and fermented sucrose, L-rhamnose, and alpha-methyl-D-glucoside, but(More)
Toxoplasma gondii antibodies were found in the sera of 22.86% of people in the Jos area of Plateau State, Nigeria. The incidence of antibodies in Nigerian food animals was 17.40%, the highest being in sheep (21.92%) and lowest in goats (13.88%). Cattle and horses were roughly equally infected--about 17.0%. The zoonotic potential of T. gondii in food animals(More)
Of 1400 pupils from two public primary schools in Ekpoma, Edo State, Nigeria, who were screened for dermatophyte infection, 188 (13.4%) were infected. The causative agents isolated included Microsporum audouinii in 88 (46.8%), Trichophyton mentagrophytes in 48 (25.5%), T. rubrum in 40 (21.3%), T. tonsurans in four (2.1%) and Epidermophyton floccosum in(More)
Two hundred and fifty apparently healthy pregnant women attending the Obstetrics and Gynecology Clinic of the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria were screened for a comparison of the prevalence of HIV seropositivity and hepatitis B surface antigenemia (HBs Ag) amongst them. The Karpas AIDS cell test for HIV seropositivity and Bioman(More)
