Escherichia coli bacteraemia in patients with and without haematological malignancies: a study of strain characters and recurrent episodes.

We compared serotypes, virulence factors and susceptibility to antibiotics of Escherichia coli strains isolated from 282 patients with bacteraemia. Thirty-five of these were neutropenic patients with haematological malignancy and 247 were patients with a normal or raised total white blood cell count and no haematological malignancy. Strains isolated from recurrent bacteraemia were also bio- and ribotyped.

A comparative study of nosocomial and community-acquired strains of Escherichia coli causing bacteraemia in a Danish University Hospital.

In a previous study we found a considerably higher mortality rate in patients with nosocomial (NO) compared with community-acquired (CA) Escherichia coli bacteraemia. To establish whether this was due to host differences or to differences in the infecting bacteria, we compared 205 NO with 172 CA bacteraemic isolates of E. coli with respect to serotype, virulence factors and antimicrobial susceptibility.

Bacteraemia due to Escherichia coli in a Danish university hospital, 1986-1990.

433 episodes of E. coli bactereaemia over a 5-year period in a Danish university hospital were studied with special emphasis on possible differences between nosocomial (NO) and community-acquired (CA) cases. Data from 186 males and 247 females with ages ranging from 9 days to 94 years were recorded.

Clonal relationships among Escherichia coli serogroup O78 isolates from human and animal infections.

We investigated the clonal relationships among 63 Escherichia coli strains of antigen serogroup O78 isolated from infections in humans, cattle, sheep, pigs, and chickens. Both septicemic and enterotoxigenic isolates were included in the study. A main group of 55 E.

Cluster of multiresistant Escherichia coli O78:H10 in Greater Copenhagen.

A multiresistant, lactose-negative Escherichia coli O78:H10 was isolated from 19 patients in Greater Copenhagen over a period of 8 months. At least 14 cases were community-acquired. 18 isolates originated from urine cultures and 1 from a faecal sample.
