ABSTRACT This study was carried out in two phases. The first phase involved the determination of the prevalence of Aeromonas species and Plesiomonas shigelloides in patients, with and without diarrhoea, reporting at the enteric laboratory of the Department of Medical Microbiology and Parasitology, Lagos University Teaching Hospital (LUTH), Idi-Araba, Lagos; over a 12-month period of October 1986 through September 1987. In the second phase the characteristics of isolates thus obtained were exa...
ABSTRACT The Biology or Plasmodium yoelii nigeriensis in rodents and the reaction of rats and nice to the infection were studied. In investigations into the course of infection of Plasmodium Yoelii nigeriansis. in rats and nice, it was found that adult nice, baby nice and baby rats were susceptible to the infection, while adult rats were totally resistant. The infection was rapidly fatal in both adult and baby mice while in baby rats, it was tolerated until the animals were 7 weeks old, after...
ABSTRACT The Mycobacterium tuberculosis complex (MTBC) is the causative agent of human and animal tuberculosis (TB). Complex membership signify how closely related they are clonally. Since the true nature of an organism lies within the genes, this molecular-based study explored unique regions of variation or polymorphism within the chromosomes that serve as targets for differentiaton, to improve our understanding of this unique group of bacteria. While extensive data exist for the molecular c...
ABSTRACT The microbial quality of materials and final products of Chemical and Allied Products Limited (CAPL), rentable paint industry in Lagos area were analyzed. The bacterial population in the fresh paint samples monitored at two weeks intervals for a period of ten months ranged from 16x 10 - 7x10 ml while the fungal population ranged from 10 x 10-55 x 10 cfu/ml. The isolated bacterial sits were identified as Bacillus polymyxa, B. brevis, B.laterosporus, Proteus mirabilis, Escherichia coli...
SUMMARY Antisera were produced against the most prevalent Campylobacter strains 'LA 4', LA 12', 'LA 36', 'LA 53, LA 78 and 'LA 1214' isolated and identified in Lagos, Nigeria. A total of two hundred other Campylobacter strains were screened using the six antisera produced to determine their serogrouping, Eight (4.08) of the strains reacted positively with antiserum raised against strain LA 4", seventy-seven (38,58) with antiserum raised against strain 'LA 36"; eleven (5,5%) reacted with the a...
ABSTRACT Malaria has played an important role in the history of mankind because it is a constant threat to human health and it affects economic development and growth in areas highly affected by the disease. The disease is more lethal in children 0-5years, pregnant women and in people from non-malaria endemic areas. An estimated 247 million cases, nearly a million deaths, mostly in children less than five years old were attributed to malaria (WHO, 2008a). Nigeria accounts for a quarter of all...

ABSTRACT The occurrence of Salmonella is a global challenge in the public health and food production sectors. Contaminated beef and animal feed with Salmonella may lead to infections of humans through food chain. The present study investigated the prevalence, serovar and antimicrobial resistance of strains of Salmonella serovars isolated from beef (meat cuts, meat fluid and carcass swabs) and animal feed (meat-and-bone, and blood meal) samples from the abattoirs in Namibia. Beef (9508) and an...
ABSTRACT The study was conducted to investigate the antibacterial activities of stem and leaves from Terminalia sericea and the live and dead bark from Combretum imberbe. The aqueous and organic crude extracts of the two plants were tested on Gram-negative bacteria Escherichia coli, Shigella sonnei, Serratia marcescens, Helicobacter pylori and Gram-positive bacteria Enterococcus faecalis, Staphylococcus aureus and Clostridium perfringens using the disk diffusion method. All the crude extracts...
