Predominant Phage Type Research Articles

Staphylococcal bacteremia and hexachlorophene bathing. Epidemic in a newborn nursery.

An outbreak of staphylococcal bacteremia in healthy, full-term neonates occurred in the newborn nursery at a large county hospital not employing prophylactic hexachlorophene bathing. Seven infants had staphylococcal bacteremia and one had omphalitis. Two of the three isolates obtained for phage typing were type 86, and the other was 3c/71. Staphylococcal colonization rate in the nursery was 64% when the outbreak was recognized; 86% of these isolates were type 86. No predominant phage type was isolated from nursery personnel. The outbreak followed a six-month preliminary study that showed a rise in staphylococcal colonization rate from 2.2% with hexachlorophene bathing to 67% with a nonhexachlorophene-containing preparation. In a community survey of infants born during the two months prior to the epidemic, seven of eight babies with lesions were infected with Staphylococcus aureus type 86.

Phage Types of multidrug resistant Salmonella species in a rural area of Maharashtra, India

Objective: The aim of the present study is to know Phage typing and antimicrobial susceptibility pattern of Salmonella species. Methods: A total of 32 Salmonella species isolated from stool and blood specimen were included in the study. They were sent for phage typing to Lady Hardinge Medical College, New Delhi. Antimicrobial susceptibility was done by using Kirby Bauer disc diffusion method. Results: Majority of Salmonella typhi belongs to phage type E1 and biotype I. Decreased susceptibility of the isolate was observed to Ampicillin, Cotrimoxazole, Cephalexin and Gentamicin. Majority of the isolates were sensitive to Ciprofloxacin. Conclusion: Predominant phage type was E1. The antibiotic sensitivity pattern is changing and resistant cases are emerging due to inappropriate use of antibiotics.
