ABSTRACT The effect of spent engine oil on soil properties and growth of Spinach (Spinacia olereacea) was investigated. Five treatments (0, 20, 40, 60, 80)ml of the spent oil were applied to soil in perforated poly bags with Spinach strands at four weeks after stabilization. Soil analysis showed that spent engine oil had no effect on both the pH and texture of the soil. Organic C, Na and Mg in the contaminated soil increased compared to control. There was decreased in concentration of P due t...
INTRODUCTION Cholera is an acute bacterial infection of the intestine caused by ingestion of food or water containing Vibrio cholerae, serogroups O139, it is a disease characterized by profuse diarrhea accompanied with a severe dehydration and loss of electrolyte (Colwell and Huq, 1994), caused by toxigenic Vibrio cholerae, a serologically diverse, environmental, and gram-negative rod bacterium (Li et al.,2002). In the absence of appropriate treatment, there is a high mortality rate. Cho...
INTRODUCTION In the production of food, it is crucial to take proper measures to ensure its safety and stability during the shelf-life. At present, many food industries are faced with different microbiological problems such as emergence of new pathogens and pathogens not previously associated withfood consumption, as well as the ability of microorganism to adapt and its resultant mutation that has given rise to altered food safety (Galvez et al., 2007). The empirical use of microorganism...
1.0 INTRODUCTION Back in 1928, Alexander Fleming began the microbial drug era when he discovered in a Petri dish seeded with Staphylococcus aureus that a compound produced by a mold killed the bacteria. The mold, identified as Penicillium notatum, produced an active agent that was named penicillin. Later, penicillin was isolated as a yellow powder and used as a potent antibacterial compound during World War II. By using Fleming’s method, other naturally occurring substances, such as chl...
Pyrexia of unknown origin (PUO) is fever that occurs for no apparent reason with failure toestablish diagnosis within one week of investigation. The fever involves temperatures ofgreater than 38.3oC which occurs sporadically for more than three weeks. Fever resolvesusually after about 3 days but can take 2 weeks.Dengue is a tropical mosquito borne-viral disease and is marked by high fever and severe muscle and joint pains. It is caused by any of four antigenically and genetically distinct vir...
ABSTRACTIn a research conducted to ascertain the antimicrobial activity of watermelon (Citrullus lanatus) bark on organisms such as Escherichia coli, Slamonella typhi and Staphylococcus aureus using the ethanol and auqous extracts of the watermelon bark applying agar-well and pour-plate sensitivity technique. It was observed that the ethanoic extract (dry) of watermelon bark on agar well showed a high inhibitory activity of Staphylococcus aureus and Escherichia coli and shows a moderate in...
ABSTRACT A human or animal with an infection has another organism inside them which gets its sustenance (nourishment) from that person, it colonizes that person and reproduces inside them. The human with that organism (germ) inside is called the host, while the germ or pathogen is referred to as a parasitic organism. Another name for an organism that causes infection is an infectious agent. It is only an infection if the colonization harms the host i.e parasitic relationship. It feeds and mu...
