Prevalence of Hepatitis B serological markers among HIV infected patients

Abstract Abstract Background: Occult hepatitis B infection (OBI) is defined as serologically undetectable hepatitis B surface antigen (HBsAg-ve), despite the presence of circulating HBV DNA (Allain, 2005). It has been documented that one of the frequent complications of HIV infection is hepatitis B co-infection and due to the common methods of transmission of these two viruses, the incidence rate of co-infection is increasing (Chen et al., 2011) Objective: To determine the prevalence of HBV s...

Investigating The Presence Of Staphylococcus Aureus And Escherichia Coli In Dairy Products

INTRODUCTION Dairy products are various products derived from cow’s milk or that of other female mammals such as goat, sheep, yaks, horses, camel. Dairy products include yoghurt, nono (fermented cow’s milk, madara (unfermented cow’s milk, cheese, whey, condensed and evaporated milk.) (cultureforhealth, 2015). Yoghurt, nono, Madara has become so highly valued in humans diet because of their nutritional values and their culinary possibilities (George and pamplon, 2006) Yoghurt is ma...

Lupus Outbreak in Nigeria

Systemic lupus erthematosus (SLE) is an autoimmune disease in which tissues andcells undergo damage mediated by tissue binding auto-antibodies and immune complexes(McGraw, 2005).General findings include a much higher incidence in women estimated to be up to10-12 times than in men. The highest incidence is between 15 and 44 years of  age.(Academic press, 1999)  It, therefore, means that as much as ninety percent of patientsare women of childbearing age. Incidence of SLE has been studied in g...

ISOLATION OF SERRATIA MARCESCENS FROM THE SOIL AND INVITRO PRODIGIOSIN PRODUCTION AS SOURCE OF ANTIBIOTIC, ACTIVE AGAINST OXACILLIN RESISTANT STAPHYLOCOCCUS AUREUS

  ABSTRACT This research work involve the isolation of two isolates titled RMN1 and RMN2, belonging to the Genus Serratia  from two soil samples collected from the following two strategic locations in university of Abuja, permanent site: Termite hill besides Girls hostel dump ground and from Faculty of Agricultural Science farm land. The isolates were morphologically distinct on the basis of spore colour, aerial and substrate mycelium formation and production of diffusible pigment. Isolat...

Biofilm Formation and Antibiotic Resistance of Uropathogens Isolated from Patients attending a Teaching Hospital in Anambra State Nigeria

The main aim of this research was to characterize the enterobacterial uropathogens with respect to drug resistance in Awka, south-eastern Nigeria. The following enterobacterial uropathogens isolated from patients attending Chukwuemeka Odumegwu Ojukwu University Teaching Hospital, Awka were studied: E.coli (58), Salmonella spp. (15), K. pneumoniae (14), Citrobacter freundii (10) and Enterobacter aerogenes(3). Their antibiotic susceptibility patterns against major classes of antibiotics were e...

PRODUCTION OF INSECTICIDAL COMPOUNDS USING BACTERIA AND FUNGI

Pest and diseases have a serious effect on food production. Global crop yields are reduced by 20 to 40% annually due to impact of pests and diseases.Indiscriminate use of insecticides to combat insect challenges, have increased the selection pressure leading to resistance in insects. In such a situation, alternate options of insect control are advocated. The use of microbial insecticidal compounds offer adequate levels of insect control and pose fewer hazards.Microbial insecticidal compou...

Hepatitis B

Hepatitis B is an infection of your liver. It can cause scarring of the organ, liver failure, and cancer. It can be fatal if it isn’t treated.It’s spread when people come in contact with the blood, open sores, or body fluids of someone who has the hepatitis B virus. The disease don’t last a long time. Your body fights it off within a few months, and you’re immune for the rest of your life.Hepatitis B is a contagious liver infsection caused by the hepatitis B virus (HBV).  The natural...

PREVALENCE OF CHIKUNGUNYA VIRUS IgG AMONG CHILDREN AND ADULTS IN GOMBE

ABSTRACT Infection with Chikungunya virus (CHIKV) is highly infectious disease that causes some dermatological manifestations and clinical symptoms. CHIKV is a member of the family Togaviridae. Structurally, it has an encapsidated genome composed of single-stranded RNA. This study is carried out to determine the seroprevalence and prevalence of CHIKV among the residents of Gombe state. Total number of 90 samples was collected randomly from both sexes between the age group of 2-70 years. The b...

Occurrence and Multiple Antibiotic Susceptibility Profile of Bacterial Pathogens Isolated from Patients with Chronic Respiratory Diseases

Abstract Objectives: The present study reported the antibiotic susceptibility profile and pattern of pathogens isolated from in- and out-patients with respiratory tracts infections. Methods: Sputum and throat swab samples were collected aseptically from subjects and cultured on the appropriate bacteriological media. Bacterial isolates were identified using biochemical tests and the identity of the isolate was later confirmed using Analytical Profile Index 20E kit. Antimicrobial susceptibilit...

Evaluation of Inhibitory Zone Diameter (IZD) of crude Spondias mombin (Linn.) extracts (root, leaf, and stem bark) against thirty infectious clinical and environmental isolates.

Abstract The purpose of this work is to evaluate the Inhibitory Zone Diameter (IZD) of crude Spondias mombin extracts against thirty infectious clinical and environmental organisms. The root, leaf and stem-bark of S. mombin were harvested and air-dried. The dried S. mombin was milled into powdered form using manual grinder. Powdered S. mombin (1kg) each of the different S. mombin parts was extracted with 3 L of 70% (v/v) ethanol, ethyl acetate and distilled water for 72 h at room temperature....

ABSTRACT The study determines the antifungal effects of aqueous, ethanolic and methanolic extracts of Garcinia kola on some selected fungal isolates and their phytochemical constituents. The antifungal sensitivity and Minimum Inhibitory Concentration (MIC) were determined by agar well diffusion and agar dilution methods, respectively using Sabouraud dextrose agar. The minimum fungicidal concentration (MFC) was determined using samples with no visible growth in the MIC assay and sub-cultur...
