Abstract

This study was conducted to investigate the dominate aerobic bacterial agents causing diarrhea in children
and study its susceptibility against some antibiotics.
For this goal, 460 stool specimens were collected from infected children aged from 1 month to 5 years at
Diwaniya teaching hospital for obstetrics and pediatrics from April up to November 2004, study include
also the evaluation of some factors (age, sex, and residence area) on infected with diarrhea.
Samples were cultured on different selective and differential media include blood agar, MacConkey agar
and S-S agar and identified them by using biochemical tests with ensuring the results by API-20E system
and serological tests ..
Results showed the obtaining of 214 bacterial isolates belonging to seven different genera (E.coli,
Salmonella, Proteus, Klebsiella, Shigella, Enterobacter and Staphylococcus aureus) with the percentage
(45.79%, 14.94%,13.08%, 12.61 %,10.7%,1.86%, and 0.93%) respectively.
The study showed that there are no differences between increases or decrease of diarrhea infection and
season or month and the highest ratio of infection were in September, August, June, and May.
Regarding age influences, the first age class (1-6) months was subjected to infection more regarding sex. It
appeared that the percentage of infection in male was 60.43% in compare with females 39.5% while the
ratio of infection in city's children was 68.47%, whereas in village's children it was 31.52%.
Susceptibility test of these isolates to different antibiotics by using disc diffusion method showed that most
of these bacterial isolates were sensitive (100%) to ciprofloxacin and resistant (100%) to Ampicillin, while
differed in its sensitivity to the other antibiotics.
