Symptoms of this infection include vaginal itching, irritation of the vulva and vagina, discharge and burning sensation around the genito-urinary tract of infected individuals. This study was conducted to detect and determine the prevalence of vaginal candidiasis in pregnant women attending antenatal care in selected hospitals within Gusau, Zamfara state, Nigeria. Vaginal swab samples of 300 pregnant women aged between 15 and 40 years were collected and mycologically analysed using standard microbiological procedures for the detection of Candida albicans usually implicated in cases of vaginitis. Out of the 300 vaginal swab samples analysed, 65 (21.67%) were found to be positive. Women aged 26-30 had the highest percentage distribution of C. albicans. Distribution of the organism was observed to be least among those aged 36-40. The study underscores the need to periodically determine the prevalence of vaginal candidiasis among pregnant women so that adequate measures can be put in place to forestall any negative effect of such infection on the mother and unborn child.

Peer reviewed articles published in the last two decades involving seafood and antibiotics were searched on the Scopus database using the search words “seafood” and “antibiotics’’. The retrieved data were then analyzed based on the total research outputs, countries and affiliation of authors, sources of funding, keywords used by the authors, citations and collaborations using both add-on analytical tool, Microsoft Excel and VOS viewer for data visualization. A total of 447 research outputs by 710 authors affiliated with 1173 institutions from 74 countries using 1051 keywords were obtained. Original research articles accounted for the highest percentage (87.7%) and published across 166 different peer-reviewed journals. Most of the original research articles were published in the International Journal of Food Microbiology 27(16.3%)...

They can be obtained through steam-distillation, solvent-extraction, resin trapping, and mechanical method such as cold pressing. Plant oil constituents contribute to the beneficial or adverse effects against pathogenic bacteria because the skin harbors diverse bacteria, and alterations to these bacteria can affect the effectiveness of skin as a blockage to infectious disease or create skin injury. Soaps formulated with plant oil have been found effective both in cleaning and killing bacteria. The aim of this study is to determine the antibacterial activity of some selected seed oil from plant for soap formulation. Soap tablets were produced through the cold saponification process by reacting to the selected seed oils (baobab oil, canary oil, castor beans oil, wild grapes, cottonseed oil, onion oil, and calabash seed oil) with sodium hydroxide. The sodium hydroxide solution was added to each seed oils in ratio 1:1 v/v and activities of the soap against Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, and Salmonella typhi were investigated. The results revealed that soap formulated with Onion seed oil possessed the highest activity against all bacterial strains. However, cottonseed oil, canary melon oil possessed good activities against all strains of bacteria only at higher concentrations (150mg/L and 200mg/L). The result suggests that the formulated soap especially those formulated with Onion seed oil, cottonseed oil, and canary melon oil will be effective in the eradication of skin bacteria. The oils can be used as an antibacterial agent in the industrial production soaps.

The drying is done in open and on a mat or at times on bare floor including shoulder of roads or any surface that is unhygienic. Tomato is an important vegetable crop that is consumed worldwide. It has numerous vital vitamins and other nutrients that promote health and well being of humans. Tomato has been found to be beneficial in the management of diseases such as cancer, cardiovascular and so on. The improper drying of tomato and poor storage has in many reports been found to be more suitable for pathogenic fungi to grow and produce their secondary metabolites which may be poisonous to humans. A total of fifty (50) dried tomato samples were obtained from nine (9) different markets in Gusau, Zamfara state, Nigeria and screened for the presence of fungi. Isolation and identification was done using cultural and cellular examinations. Fungi Isolation was carried out on potato dextrose agar and malt extract agar, samples were inoculated and incubated for at 5 days at 25 o C. Identification of the fungi was based on colonial morphology on the plates and microscopic observation in comparison with mycological key. Fungi isolated are mostly of Aspergillus and Penicillium genera. Aspergillus niger was found to be the highest occurring fungi with 52.3%, other fungi isolated were Penicillium oxalicum, Aspergillus flavus each accounting for 6.8% of isolated and identified fungi. Penicillium chermesium, Aspergillus parasiticus, Aspergillus fumigatus, Curvularia americana with 4.5% each and Rhodotorula glutinins, Fomitopsis meliae, Penicillium vericussum, Chaetominum, Aspergillus nidulans and Aspergillus sydowii with 2.3% each. Some of these fungi species are known to produce toxins which could be harmful to both humans and livestock.
