    Epidemiologic Survey of HBV, HCV and HIV Infections in a Pregnant Women Population in Central Nigeria: A Cross- Sectional Study

    Parallel and overlapping of HBV, HCV and HIV infections in pregnant women is a major public health problem. In this cross-sectional study, we evaluated the parallel and overlapping infections of HBV, HCV and HIV among pregnant women population in Keffi, Central Nigeria between June through August 2019. Four hundred (400) women blood specimens were collected from major Hospitals in Keffi for the study after informed consent and ethical approval were retrieved and a structured questionnaire was administered to each women before sample collection. Specimens were analyzed for HBsAg, anti-HCV and anti-HIV antibodies using rapid test kits according to the manufacturer’s instructions. Information obtained were statistically analysed using SSP version 2.80 and any P values less than 0.05 were reflected statistically significant. Out of the 400 women screened, there was overlapping infections of 11 (2.8%), 6 (1.5%) and 3 (0.8%) for HBV/HCV, HBV/HIV and HCV/HIV respectively. Parallel infections were 22 (5.5%), 12 (3.0%) and 14 (3.5%) for HBV, HCV and HIV. Only educational status was statistically related to HCV infection (p < 0.05). Those women that were below 20-years-old had the highest prevalence of HBV and HIV, meanwhile, women aged > 51 years recorded the highest prevalence for infection due to HCV. The parallel and overlapping HBV, HCV and HIV infections reported in this study is a stimulant for more proactive measures towards eliminating these viruses among pregnant women in Nigeria.

    Soil microbial status under different land use systems in Gombe state, Nigeria
    (Department of Microbiology, Nasarawa State University, Keffi, 2020-06-23) Theophilus, James; El-Hassan, Aliyu; Ishaku, Deborah,; Yauta, Sani Abubakar; Haruna, Isa Mohammed; et. al
    Microorganisms are of primary importance for soil quality and natural productivity. Four land use systems viz., Forestry, Horticulture, Agriculture and Pasture at four different locations viz., Bajoga, Gombe, Boderi and Kanawa were identified in determining population of microorganisms in the soil. The samples were collected, numbered and labelled with date and site of collection in an air-tight pre-sterilized polyethene bags before transportation to the laboratory. Serial dilution pour plate technique was used for estimation of total bacterial, fungal, actnomycetes and azotobacter using specific media. The plates were incubated at temperatures specific to particular microbe for 2 – 3 days. The colonies that developed on media were counted by electronic colony counter. The microbial counts were expressed as colony forming unit per gram of soil (CFU/g soil). The highest bacterial count (CFU/g) was found in forest land use with the mean value (192.66) and the lowest (41.33) was found in agricultural land use system. The highest total fungal count (CFU/g) was recorded in forest land use with the mean value (77.33) and the lowest (10.33) was found in agricultural land use system. The highest total viable actinomycetes count (CFU/g) was recorded in forest land use with the mean value (62) and the lowest (3) was found in agricultural land use system as compared to other soils in the study area. The perusal of data reveals that for the total azotobacter count (CFU/g), the highest was recorded in forest soils because of the presence of more organic matter with mean value (22.66) as compared with the other land use systems. The lowest was found in agriculture (4.33). Lowest microbial count in agricultural soils may result to poor soil quality and natural productivity which may lead to famine a natural disaster. Planting of cover crops will improve soil structure, enhance soil fertility and sustain or increase soil organic matter and soil biological activity.
