FiftyEscherichia coli strains isolated from stool samples of 51 healthy children, 143 strains isolated from stool samples of 327 children with diarrhea and 24 strains isolated from stool samples of 21 children with suspected hemolytic uremic syndrome were examined for the presence of Shiga toxin-producingE. coli virulence factors (shiga toxin 1 and 2,(More)
Enterohaemolysin production was found in 11 (20.3%) out of 54 Escherichia coli strains isolated from stools of infants with dyspepsia and in 3 (2.3%) out of 130 E. coli strains isolated from urinary tract infections. Enterohaemolysin producing E. coli strains isolated from stools belonged to O groups 25 and 111 and the strains from urine to O groups 1 and(More)
In Escherichia coli strains isolated from faeces and smears from the rectum in haemolytic-uraemic syndrome of a child and healthy relatives the authors assessed the biochemical activity, antigenic characteristic, sensitivity to twelve antimicrobial substances and factors of virulence. Sorbitol negative strains were isolated from the ill child and his(More)
Changes in leukocyte counts and in the gut microflora of laboratory rats irradiated with a single whole-body dose of γ rays (5.0 Gy) were determined. The number of leukocytes was lower especially 1 and 2 weeks after irradiation. A significant decrease in lymphocytes was observed 1 week and in monocytes 1 and 2 weeks after irradiation. In parallel with these(More)
Changes in leukocyte counts and in the gut microflora of laboratory rats irradiated with single whole-body dose of gamma rays (5.0 Gy) were determined. The number of leukocytes was lower especially 1 and 2 weeks after irradiation. A significant decrease in lymphocytes was observed 1 week and in monocytes 1 and 2 weeks after irradiation.
