Detection of virulence factors in alpha-haemolytic Escherichia coli strains isolated from various clinical materials.

In total, 201 alpha-haemolytic Escherichia coli isolates from various clinical materials (urine samples and vaginal and rectal swabs) were examined by PCR for the presence of genes for the virulence factors alpha-haemolysin (hly), cytotoxic necrotising factor type 1 (cnf1), P-fimbriae (pap), S/F1C-fimbriae (sfa/foc), aerobactin (aer) and afimbrial adhesin (afaI). Among vaginal isolates, 96% were positive for cnf1, compared with 80% of urine strains (p 0.02) and 63% of rectal strains (p 0.

Non-albicans Candida species isolated from plastic devices.

In this work we point out an occurrence of non-albicans Candida species isolated from catheters, cannulas and drains. We detected eight non-albicans Candida species in 49 examined samples: C. parapsilosis (n = 26), C.

[Sorbitol-negative E. coli 016 in a 10-year-old child diagnosed with hemolytic-uremic syndrome and in his asymptomatic father].

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 father. The strains belonged into serogroup 016.

[Characteristics of E. coli strains isolated in infantile diarrhea].

In a group of 50 strains of E. coli isolated from infants hospitalized on account of diarrhoea the authors investigated, based on the phenotypic manifestation and in a selected number of strains also genotypic factors of virulence: fimbrial adhesins, aerobactin, haemolysins, colicins, toxic and lethal action in mice, seroresistence and resistance against tetracycline, streptomycin, chloramphenicol, kanamycin, ampicillin and sulfamethoxidine. All strains had one to eight factors of virulence.
