Abstract

Faecal samples were taken from 20 calves with colibacillosis. The serotypes of 20 strains of E. coli isolated are listed. Enteropathogenic effects were measured by ileal loop test in rabbits (ILR) and by stomach inoculation in sucking mice (SSM). Five strains were designated as enteropathogenic by...

Abstract

Of 67 samples of farm cheese, 89.5% yielded Escherichia coli and 77.6% Staphylococcus aureus. The geometric mean counts of the organisms were 5.68 × 102E. coli/g and 5.26 × 103S. aureus/g. The cheese was considered a public health hazard.

Abstract

The K99 antigen, codified by means of plasmids which can also carry multiple resistance factors to antibiotics, is the main attachment factor of enteropathogenic E. coli in calves. The authors studied 300 E. coli strains isolated in Chile from newborn calves that had diarrhoea to determine the...

Abstract

40 cows with subclinical mastitis grade 3 (graded by California Mastitis Test, CMT) were treated either with 2 or 4 i.m. injections of sodium penicillin G (10 000 IU/kg) every 12 h or with a single i.m. injection of sulfadiazine-trimethoprim combination (15 mg/kg, Salfen) or were left untreated....

Abstract

Faecal samples from 136 steers and 120 pigs slaughtered in 2 abattoirs were examined. Enterohaemorrhagic E. coli (EHEC) strains were identified by DNA hybridization with specific gene probes for Shiga-like toxin I (SLTI) and II (SLTII). Positive strains were hybridized with specific gene probes for ...

Abstract

Faecal samples from 136 slaughtered cattle were examined for enterohaemorrhagic E. coli (EHEC) by DNA hybridization with biotin-labelled DNA probes specific for the EHEC virulence plasmid, Shiga-like toxin I (SLT I), Shiga-like toxin II (SLT II) and eae gene. 48 samples (34.5%) were found positive...

Abstract

The sensitivity of pathogenic bacteria isolated from dairy cows suffering from mastitis in different regions of Chile against antimicrobials frequently used in dairy herds is reported. The Plate Dilution Method and the Minimum Inhibitory Concentration (MIC) were used to evaluate the bacterial...
