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 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 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...
Healthy mature seeds of bambara groundnut (Voandzeia subterranea Thouars), cowpea (Vigna unguiculata), cattle bone, roselle calyces (Hibiscus sabdariffa), red palm oil, yellow maize (Zea mays), and “achi†(Brachystegia eurycoma), were purchased from Ogige market, Nsukka, Nigeria. Methods The processing methods was based on the methods of Uvere et al., (2010). Production of maize-bambara and maize-cowpea food blends The maize, bambara groundnut and cowpea seeds were cleaned by win...
Introduction Microbial fuel cells (MFCs) are bioreactors that convert chemical energy stored in the bonds of organic matters into electricity through biocatalysis of microorganisms (Potter, 1911; Cohen, 1931; Davis and Yarbrough, 1962; Moon et al., 2006). The schematic of a typical MFC is shown in Fig. 1. In the sketch below, the anodic and cathodic chamber are separated by a proton exchange membrane (PEM) (Wilkinson, 2000; Gil et al., 2003) that allows transport protons while blocking oxygen...
NOROVIRUSNorovirus (NoV), causing the winter vomiting disease, is today recognized as the most important agent of acute human gastroenteritisThe etiology of diarrheas can involve several agents, such as viruses, bacteria, and parasites. Bacterial agents are relatively more important in developing countries, whereas viral agents are more relevant in industrialized countries. The importance of these agents is related to hygiene and sanitation conditions for the population1. In 1972, a 27-nm vir...
Abstract This review lays emphasis on the research works carried out across the globe on plastic degrading bacteria. The field of Microbiology is proving to have immense importance in eradicating pollutants from the environment in the long run. One of the most worked on research is on bacterial species that can degrade biodegradable plastic. Biodegradable plastics are made of monomers which bond via ester or ether bonds. Plastics are considered to be one ...
