Abstract
The aim of this work is to isolate Aeromonas from stool specimens in cases of gastroenteritis in children below the age of 5 years, healthy controls and from different drinking water supplies in Minia Governorate. Then to identify the isolated strains biochemically and study their antimicrobial resistance. The study included both clinical and environmental samples. 200 clinical stool specimens collected from children (100 children suffering from gastroenteritis & 100 children were apparently healthy). The environmental samples were 40 drinking water samples obtained from the different water supplies in Minia governorate including urban and rural sources. Sixty four strains (64%) of Aeromonas species were isolated from one hundred children with gastroenteritis. Aeromonas was also isolated from 40 of one hundred asymptomatic children. From 40 drinking water samples, 18 (45%) Aeromonas strains were isolated. All Aeromonas strains were tested for hemolytic activity on blood agar & it was found 56.3% among cases, 30% among controls and 33.3% in water samples. A. hydrophila (representing 81.3% of cases, 90% of controls and 85.2% of water samples) was the most common species among all the studied groups followed by A. caviae and A. sobria. All the isolates were tested for antibiotic resitance patterns and majority of the isolates were sensitive to ciprofloxacin, nalidixic acid, amikacin, garamycin and cotrimoxazole. They exhibited absolute resistance to ampicillin.
