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 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...

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...
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....
-the aim of this study is to carried out the Antimicrobial and phytochemical effect on five medicinal plants used as chewing sticks in Owo local government of Ondo State, Nigeria. Methods- The methods used for this study are antimicrobial assay, and phytochemical screening. The aqueous, ethanol and ethyl acetate extracts of the leaves, bark and roots of Distemonantus bentaminaitus , Anogeissus leiocarpus, Garcina kola, Piper guineense and Zanthoxylun Lessmamul for the po...
The purpose of this research work is to determine the antimicrobial activities of crude ethyl acetate and ethanolic extracts of Morinda lucida leaf, stem, and bark growing in Adekunle Ajasin University Botanical Garden against selected clinical isolates. The plant Morindal lucida falls under the family Rubiaceae known to have wide usage in traditional medicine. Morinda lucida is a tropical West African tree of medium-size about 18–25 m tall, the bark is grey to brown in color, flowers are w...
The antimicrobial activities of the ethanolic, Aqueous and Ethyl acetate extracts of five Nigerian medicinal plant used as chewing sticks were tested against five microorganism, three bacteria and two fungi. The five medicinal plant tested are Vitellaria paradoxa, Vitex doniana, Sarcorcephalus latiolia, Vernonia amygdalina, Olax subcorpidica and the microorganisns are Staphylococcus aureus, Neisseria sieca, Streptococcus mutans and Lactobacillus salivarius and Actinomycetes viscosus. Out of t...
Bridelia ferruginea is commonly grown in Western Tropical Africa. The purpose of this research work is to determine the antimicrobial activities, qualitative and quantitative phytochemical screening, elemental composition, proximate analysis and anti-nutrient composition of purified fraction of Bridelia ferruginea extracts. The organisms used for this research are Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 25922, Klebsiella pneumonia ATCC 35659, Pseudomonas aeruginosaATCC 25619,a...
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 ...
ABSTRACT In the present study, we investigated the prevalence of few bacterial organisms associated with urinary tracts infection and their antimicrobial susceptibility patterns. Total of Ninety (90) midstream urine samples were collected from outpatients with respect to their age group, gender and marital status attending health facility in Benue State University Teaching Hospital Makurdi. Each 0.1ml of urine sample was cultured on MacConkey agar and colonies showing lactose fermentation we...
Food industry wastes are an essential environmental contamination source. A large number of microorganisms including bacteria, yeast and fungi produce different types of enzymes like protease, lipase, chitinase, chitosan and ligninolytic enzyme having high biotechnological interest such as food processing, detergent, textile, pharmaceutical products, and medical therapy. Microbial synthesis of enzymes has been reported to be influenced by various factors such as carbon sources, nitrogen sourc...
Street vended foods are the major source of food borne diseases in most parts of sub-Saharan Africa including Nigeria. In this study, six samples each of six different vended foods obtained in Calabar municipality were evaluated for bacteriological quality and presence of Staphylococcus aureususing standard microbiological techniques. Each food was examined macroscopically for evidence of spoilage, followed by culture isolation for Staphylococcus aureus. The organisms isolated were subjected ...
Aims: To investigate the prevalence and susceptibility pattern Salmonella enterica strains to ceftriaxone in southwestern Nigeria. Place and Duration of Study: Faculty of Pharmacy, University of Ibadan, Nigeria from November 2012-May 2013. Methodology: Isolates of Salmonella enterica were characterized by established standard cultural and biochemical tests and was screened in-vitro for their sensitivity to different antibiotics (ampicillin, amoxicillin, chloramphenicol, cotrimoxazole and ceft...
This paper is titled 'Microbiology of Meat Spoilage'. It clearly explains those Spoilage microorganisms associated with the Spoilage of meat and meat products and also the preservative method to be used in preserving meat. On the basis of its high moisture content and presence of adequate nutrient, meat is regarded as the most perishable product (Magnus, 1986) and thereby highly susceptible to spoilage by microbial proliferation. Apart...
