Outbreak of S. aureus and P. aeruginosa infections in a burn center

This study was conducted in the Burn Center of Kasr EI-Aini Hospital in the period from January 1995-February 1996 to study the most common organisms causing sepsis in burn wounds. In December 1995 and January 1996 we noticed an increase in the incidence of isolation of P. aeruginosa [75%] and S. aureus [65%] from wound biopsies. To study their epidemiological relatedness swabs were taken from hands, nose, throat, skin and perineum of burn patients of different age and sex groups admitted during this period. Swabs were also taken from hands and nose of doctors, nurses, working personnel as well as from the environment and all instruments and antiseptic solutions used during dressing of the wound. To establish the spread of the outbreak, the suspected strains were subjected to plasmid profile analysis which revealed the role of the health care personnel, patients and betadine solution in disseminating the outbreak strains

Diagnosis and screening of children with caries using microbial tests

The purpose of this study is to evaluate the efficiency of Alban test as adiagnostic test for caries predictions and to relate its acid production tothe number of Lactobacillus and Streptococcus mutans in saliva of children. The study sample consisted of sixty caries active and thirty caries freepreschool children as a control. Clinical examination was done. Salivasamples were collected and 3 tests were adopted for each child. Highcorrelation was detected between dmf index and acid produced from Alban test[r=0.9]. Similar correlations were found between dmf index and Lactobacillusand Streptococcus mutans count [r=0.86 and 0.72 respectively]. AccordingAlban test can be used as a caries predictors in children. It can be done indental clinic due to its simplicity as a routine diagnostic test foridentification of children at caries risk
