Information on the use of certain preventive measures to control malaria transmission and also the need to keep a clean environment for more healthy living is given. A total of 200 subjects attending UITH were recruited into the study. Their blood samples were collected and analyzed microscopically for the ...
ABSTRACT Effect of ultraviolet radiation on survival, infectivity and maturation of Schistosoma mansoni cercariae. International Journalfor Parasitology 20: 893-897. 5. mansoni cercariae exposed to ultraviolet radiation for 1,3, 5,10 and 20 s as well as non-irradiated cercariae remained actively motile 30 min post-irradiation. Thereafter the activity decreased with increasing dose level of radiation and age of cercariae. There was no significant difference between the rates of attachment of...
ABSTRACT Background: Molluscum contagiosum (MC) infection is caused by a pox virus and the virus is probably passed on by direct skinto-skin contact which may affect any part of the body. There is anecdotal evidence associating facial lesions with HIV-related immunodeficiency. This study was aimed to determine the prevalence and associated risk factors of Molluscum contagiosum infection among PLWHAs attending ART clinic at the University College Hospital, Ibadan, Nigeria. Methods: This is a ...
ABSTRACT The upsurge of Candida albicans as the fourth most common causative agent of nosocomial infections necessitated the evaluation of a range of disinfectants for their efficacy against this organism. This project work was designed to basically determine the anti-Candida efficacy of three commonly used, commercially available disinfectants, namely Savlon, Septol, and Izal, using suspension test technique. The test organism was challenged with various concentrations (25%, 50%, 75% and 10...
Bioluminescence is the process by which certain living organisms produce light through a seriesof enzymatically catalyzed biochemical reactions (Brodl et al., 2018). Any organism that iscapable of exhibiting or carrying out bioluminescence is termed a bioluminescent organism.Bioluminescence is a phenomenon that has been found in almost all branches of the evolutionarytree (Tyulkova et al., 2009), meaning that representative organisms from ...
Abstract: This study was aimed at determining the antibacterial effect of the leaf extract of Buchholzia coriacea (Wonderful Kola) on nasal isolates. Nasal isolates were collected from one hundred students of the Delta State Polytechnic, Ogwash-uku, Delta State. The antimicrobial activity of the methanolic extract of the leaves was assessed against nasal isolated microorganisms (E.coli, Citrobacter species, Klebsiella species, and Proteus species) using the agar well diffusion method. Inh...
AbstractObjective: To correlate the levels of bladder tumour antigen (BTA) with aflatoxin M1 (AFM) in a humanpopulation in Nigeria.Subjects and methods: A pilot, observational study was conducted with 22 human subjects randomlyrecruited from a Nigerian rural community. Serum and first morning urine of participants were analysedfor human BTA and AFM1, respectively, using quantitative ELISA assays.Results: All the subjects were positive to AFM1 (mean= 0.235± 0.072 ng/mL) while 19 were positi...
Abstract Background: The growing desires to combat antibiotic resistance among pathogenic bacteria necessitate the need to search for new antimicrobials agents from other sources such as plants. Objectives: The present study investigated the antibacterial activities and bioactive components of Nymphaea lotus and Spondias mombin against selected clinical bacteriaMaterial and Methods: Extracts of N. lotus and S. mombin were prepared by 72 hours maceration in 70%methanol. The antimicrobial susce...
Dear Editor,Infection due to Plasmodium falciparum is a serious public health threat in sub-Saharan Africa. Malaria endemic foci are often times affected by other infectious agents which may contribute to the clinical episodes of the disease. 1Hepatitis B virus is one of such infectious agents that coexistwith P. falciparum in most endemic areas. Although the accurate infection status due to hepatitis B virus infection is not yet known, an estimated 350 million persons worldwide are chronic c...
Cockroaches and houseflies pose significant public health threat owning to their ability to mechanically transmit human intestinal parasites and other disease-causing microorganisms. This study aims at assessing the vectoral capacity of cockroaches and houseflies in the transmission of human intestinal parasites. Intestinal parasite external surface contamination of 130 cockroaches and 150 houseflies caught within dwelling places in Ilishan-Remo town, Ogun StateNigeria was determined. Coc...
The study evaluated the molluscicidal effects of ethanolic leaf extracts of two Nigerian indigenousmedicinal plants; Terminalia catappa and Carica papaya. Different concentrations 2500, 630, 160, 40 and10 ppm were prepared from the stock solution of the extracts. Adult Biomphalaria pfeifferi and Bulinusglobosus were exposed to these different graded concentrations. Mortalities were observed at intervalsof time. There were strong positive correlations between mortalities observed in snails and...
AbstractBackground: Rapid and accurate diagnosis is necessary for the management of schistosomiasis in endemic areas.Objective: To assess the burden of urogenital schistosomiasis and the diagnostic efficiency of morbidity indicators of the disease in an endemic rural community of Nigeria.Methods: A cross-sectional school-based study was conducted. Urine samples of 487 pupils were screened microscopically for S. haematobium and tested for haematuria and proteinuria using chemical r...
The aim of this study is to determine the phytochemical composition, antimicrobial properties and phenotypic resistance pattern of selected enteropathogenic micro organism on Ageratum conyzoides leaf extract. Enteropathogenic isolates were collected from Adekunle Ajasin University Health Centre, Akungba Akoko, Ondo State and were identified using Microbact™ 24E Identification kit. Antibiotic sensitivity testing was carried out against the enteropathogenic organism using Kirby-Bauer disc dif...
Abstract Nonribosomal peptide synthetases (NRPSs) are multimodular enzymes that are used wholly or partly in the biosynthesis of antiobiotics; a natural product that fall into the class of secondary metabolites. NRPSs have diverse functions and have also been used in the synthesis of toxins, siderophores, or pigments, among others. Unlike other proteins, its biosynthesis is independent of ribosomal machinery. Nonribosomal peptides are synthesized on large nonribosomal peptide synthetase�...
The use of plants as medicines is an ancient practice common to especially Nigeria and Africa at large. The purpose of this research work is to evaluate the zones of inhibition, phytochemical screening and molecular docking (In-silico Approach) of Piptadeniastrum africanum against selected clinical and multiple antibiotic resistant isolates. Using agar well diffusion method, the antimicrobial activity of the stem bark and leaf extracts of Piptadeniastrum africanum was assayed against Escheric...
