The isolation of Escherichia coli from a poultry packing station and an abattoir.

The distribution and serotype of strains of Escherichia coli from a poultry packing station and an abattoir are described. The results indicated that animal faecal strains contaminated the environment and the animal carcasses.Using 150 O antisera, a high proportion of the E. coli strains were non-typable. This suggests that the serotype distribution of E. coli in animals is different from that in man.Strains with single antigenic differences were isolated, and the possibility of genetic transfer of these antigenic structures is suggested.

Further studies of Escherichia coli in babies after normal delivery.

Previous work showed that on the basis of O serotyping alone of Escherichia coli, the majority of babies acquired the same O serotype as was found in the stools of their respective mothers. Further characterization of the E. coli by H serotyping, determination of their antibiotic resistance and ability to ferment six carbohydrates showed that in the majority of cases the previous results were confirmed. In a minority of cases this further testing showed that the strains were not identical. In some instances a number of strains isolated from the same pair showed different combinations of the markers used.

Spread of Escherichia coli colonizing newborn babies and their mothers.

Most babies are colonized by the predominant strains of Escherichia coli present in their own mother's faecal flora. Those babies who did not acquire their maternal faecal flora acquired strains of E. coli belonging to a small number of the possible serotypes. Moreover, the same serotypes were found in several babies and other mothers, suggesting spread within the ward. These few strains included some of the O groups which had previously commonly been found as urinary pathogens. These strains may have increased potentialities for colonization of human bowel. Antigenic and biochemical variation was observed among the strains.

Escherichia coli serotype distribution in man and animals.

The serotype distributions of Escherichia coli isolated from animal faeces, human faeces and from meat have been compared. There were marked differences in serotype distribution in strains from man and animals. The meat strains generally resembled animal strains. The results suggest either that animal strains of E. coli are not reaching the general human population outside hospital to any great extent, or, if they do so, are failing to implant in the bowel.

Postoperative urinary infections caused by Escherichia coli.

Serological and biochemical classification of Esch. coli from the rectum and vagina of patients who developed a urinary infection after operation and the insertion of a self-retaining catheter showed that 13/20 urinary infections were caused by a type which had been present before operation in the rectum, vagina, or both.

Infant diarrhoea due to Escherichia coli 091 K? H7.

A small outbreak of infective diarrhoea occurred among babies in hospital at Winchester, England. The causal agent was found to be a strain of Escherichia coli 091 K? H7 which was resistant to several antibiotics. Epidemic diarrhoea due to E. coli 091 has previously been reported from south Germany.

Serological studies on patients with suspected legionellosis in New Zealand.

Specimens from 490 patients with suspected legionellosis from many parts of New Zealand were studied. Most of these were sera, but 36 specimens including material from lungs, pleural fluid and sputa were also examined. The sera were tested for the presence of antibodies to Legionella pneumophila serogroups 1 to 6 and Legionella micdadei. Serological evidence of legionellosis was found in 49 patients. Antibodies to L. pneumophila serogroup 6 predominated, while those to L. micdadei and L. pneumophila serogroup 1 were noted in smaller numbers. Antibodies to serogroups 2, 3, 4 and 5 of L. pneumophila were not often encountered.
