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....

ANTIFUNGAL EFFECT OF GARCINIA KOLA

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...

BIODIVERSITY CONSERVATION AND ECOSYSTEM SERVICES FOR NATIONAL DEVELOPMENT

ABSTRACT  The most amazing feature of Earth is the existence of life, and the most extraordinary feature of life is its diversity. Human beings can coexist only with the abundance of and diversity of nature. It is widely acknowledged that biodiversity underpins ecosystem functioning and that the provisioning of ecosystem services is essential for human well-being. The relationship between biodiversity and ecosystem services is not straightforward, whether more biodiversity would imply more ...
