Isolation and characterization of a toxic intracellular protein from Vibrio parahaemolyticus.

A toxic factor released from disrupted cells of Vibrio parahaemolyticus was partially purified by gel filtration after precipitation with (NH4)2SO4 at 40% saturation. The factor, which was a thermostable protein of 63 kDa, lysed human erythrocytes at a concentration of 0.15 μg ml(-1).

Bacterial air contamination of operating theatres and surgical wards of a university teaching hospital.

A study of the level and significance of air contamination in the four operating theatres and four surgical wards of the University of Nigeria Teaching Hospital, Enugu, Nigeria was carried out. A total of 48 air samples were taken from each of the operating theatres while a total of 36 air samples were taken from each surgical ward, using a "Casella slit Sampler". The means of the bacterial carrying particles per cubic foot of air varied, from theatre to theatre, from 12.

Serogroups of beta-haemolytic streptococci isolated from clinical specimens in parts of eastern Nigeria.

From 470 patients, mainly of respiratory infection, attending University of Nigeria Teaching Hospital, Enugu, Nigeria 212 (45 per cent) strains of beta-haemolytic streptococci were isolated and 25 per cent of the isolates belonged to Group B Streptococcus. Percentage isolation of other groups was A(21.2), G(20.

Antimicrobial activity of aStreptomyces species isolated from Nsukka soil.

An antibiotic-producing actinomycete was isolated from Nigerian soil and assigned to the genusStreptomyces. The antibiotic had antimicrobial activity on solid agar against both Gram-positive and Gram-negative bacteria as well as fungi.

Incidence and parametric determinants of post-operative wound infections in a university teaching hospital.

The incidence and determinants of post-operative wound infections in the University of Nigeria Teaching Hospital, Enugu was studied. During the period of study (July 1983-June 1984) 218 surgical operations from adult males and females were investigated. The overall infection rate was found to be 27.
