The Assessment of Floral Abundance and Composition of Neni-Nimo Watershed in Anaocha L.G.A. of Anambra State, Nigeria

AbstractThe research was carried out on the floral composition of Neni-Nimo watershed between November 2019 and July 2020. The research work aimed to find out the various plant species that inhabit the watershed, their abundance measures and importance values. In this study, the watershed was divided into three catchment areas, the upper, the middle and the lower catchment. Each of the catchment zones was divided into component parts, with an area of (50 m X 30 m) each. The experiment was lai...

Everything You Need to Know About the Swine Flu Pandemic

The disease is a significant health concern in most developing countries especially Cameroon.Objectives: The study aimed at assessing the risk factors associated to typhoid fever in children (0-18 years) attending the “Deo Gratias” hospital in Douala.Method: A hospital based cross sectional study from August to September 2018 was carried out in children aged 0-18...

Assessing the incidence of common bean in Cameroon

In most parts of Cameroon particularly the Menoua Division, common bean (Phaseolus vulgaris L.) is usually consumed immediately after harvest or after a few months of storage. Contamination of common bean by fungi usually occurs in the field and during storage. It is possible that the incidence of food contamination by fungi varies between field and storage. The study aimed at determining the incidence of common bean infection by fungi during harvest and during storage. Six common bean cultiv...

PREVALENCE OF MEASLES NEUTRALIZING ANTIBODY IN CHILDREN UNDER ISYEARS IN SOUTHWESTERN NIGERIA

ABSTRACTThe immune status of children under 15 years in the Southwestern region of Nigeria against measles virus was determined using the neutralization test with a view to assessing the herd immunity to the virus in these communities. A total of 256 serum samples collected from children were tested by the beta method of neutralization. Forty (15.6%) of these samples were found to be positive at a titre of 1:256, 35 (13.7%) at 1:128, 36(14.1%) at 1:64, 37(14.S0h) at 1:32. 38 (14.8%) at 1:...

Evaluation of Certain Preventive Measures to Malaria Infection

ABSTRACTThis study provides information on the infectivity rate of Plasmodium falciparum on subjects attending University of Ilorin Teaching Hospital (UITH), Ilorin, Kwara State, Nigeria. 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 ...

EFFECT OF ULTRAVIOLET RADIATION ON SURVIVAL, INFECTIVITY AND MATURATION OF SCHISTOSOMA MANSONICERCARIAE

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 attach...

MOLLUSCUM CONTAGIOSUM VIRUS INFECTION AMONGST PLWHA IN IBADAN, NIGERIA

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 ...

The Efficacy of Disinfectants on Candida albicans at Different Concentrations and Contact Times

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%, 7...

Bacterial Bioluminescence - A General overview

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),  &...

The antibacterial effect of the leaf extract of buchhozia coriacea

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...

A pilot biomonitoring study of bladder tumor antigen (BTA) in aflatoxin exposed Nigerian villagers

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...

Bioactive Constituents and Antibacterial Screening of Two Nigerian Plant Extracts Against Selected Clinical Bacteria

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.

Plasmodium Falciparum and Hepatitis B Virus Infection in Nigerian Urban Population

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...

Food-borne human parasitic pathogens associated with household cockroaches and houseflies in Nigeria

Cockroaches and houseflies pose significant public health threat owning to their ability to mechanically transmit human intestinal parasites and other disease-causing microorganisms.
