“…These serotypes are generally considered to be commonly found in urinary tract infections and reflect the predominant 0-groups in the faecal flora. Antibodies to 08 and 09 antigens were also present; these 0groups have been shown to be commonly associated with plasmid carrying resistance to antimicrobial agents (Hartley et al, 1975;Howe and Linton, 1976) (Table 3). Escherichia coli 014 agglutinins were detected in only five patients and 0119 agglutinins were not present.…”

SUMMARY Sera from 30 patients with inflammatory bowel disease (IBD) (16 with Crohn's disease (CD) and 14 with ulcerative colitis (UC)) were assayed for the presence of antibodies against 159 Escherichia coli 0-antigens and compared with sera from 16 matched control subjects. The majority of patients with IBD had agglutinating antibodies to a higher number of Escherichia coli 0-antigens and in higher titres than the control group. The number of positive agglutinins was 0-33 mean 13-8 in CD, 0-26 mean 7 9 for UC, and 0-7 mean 1 5 in controls. Eight patients with IBD and arthropathy had antibodies to fewer 0-antigens (0-7 mean 3-2). The antibodies were in the IgG and IgM, in titres corresponding to original values. No specific 0-serotypes were associated with IBD. Common serotypes, R-plasmid carrying serotypes, and those associated with shigella-like adult diarrhoea were detected. 014 was detected onlyin five patients and 01 l9in none. There was no correlation between the number of Escherichia coli agglutinins and the site and severity of the disease or type of therapy.

“…Many studies have established that calves, pigs, and poultry carry antibiotic-resistant strains of Escherichia coli in their alimentary tracts (14,16) and excrete large numbers of resistant strains in their feces (6,8,9). The occurrence of antibiotic-resistant E. coli in common food animals is believed to be correlated with the use of antimicrobial agents in animal husbandry for growth promotion or for therapeutic or prophylactic purposes (10,15).…”

The incidence of antibiotic-resistant fecal coliforms in the rectal flora of 106 healthy dogs in the Galway area was investigated. As far as could be determined, none of the dogs had received antimicrobial drugs. Half of the dogs sampled were from homes within the city boundaries, whereas the remainder were from farms within a 40-mile (24.8-km) radius of the city. Of the dogs sampled, 47 had a highly susceptible fecal coliform flora, with less than 1% of the coliform population resistant to any of the four test antibiotics. Fecal coliforms resistant to one or more of the test drugs comprised between 40 and 100% of the total fecal coliform population of 36% of the rural dogs and 13% of the urban dogs sampled. Of the 473 resistant Escherichia coli isolates studied, the highest number of associated resistance determinants encountered was 5, with a median number of 2.5. Of the E. coli isolates from rural dogs, 52% were resistant to three or more antibiotics compared with 37% of the isolates from urban dogs. A total of 64% of the isolates were shown to transfer some or all oftheir resistance determinants by conjugation. The transferability of ampicillin (77%) and chloramphenicol (70%) resistance determinants was higher than that of streptomycin (40%) or tetracycline (44%).

“…typhimurium and E. coli was determined by the disk diffusion method (Howe & Linton, 1976). The antibacterial sensitivity disks used included ampicillin (A) (25 jug), chloramphenicol (C) (50 ,ug), kanamycin (K) (30 ,ug), streptomycin (S) (25 ,ug), sulphafurazole (Su) (500 ,ug) and tetracycline (T) (50 jig).…”

“…These strains were 0-serotyped by a microtitre agglutination technique using 157 typing sera (Hartley et al 1975; t BLA, bile lactose agar; C, chloramphenicol; S. streptomycin; T, tetracycline. Howe & Linton, 1976) and biotyped on the basis of their ability to ferment five carbohydrates (Hinton, Allen & Linton, 1982).…”

SUMMARYSalmonella typhimurium phage type DT 193 survived in small numbers, in stored static slurry derived from veal calves, for the 7-week period of observation. The viable coliform count fell by 14 logs during the first 2 weeks of storage, thereafter there were only relatively small fluctuations in the coliform population. In all 735 of 752 Escherichia coli isolates examined from eight samples of slurry were resistant to 3-6 antibacterial drugs. There was no dramatic change in the overall level of drug resistance amongst the E. coli with time. Chloramphenicol resistance was recorded in 400 (55 00) of the E. coli. It was always associated with multiple resistance, with 960 of the strains being resistant to 5 or 6 drugs, although the proportion of isolates of each of the ten most prevalent 0-serotypes resistant to chloramphenicol was variable and ranged between none and 97-5 %. The use of biotyping together with 0-serotyping indicated that the E. coli population was extremely complex, although certain components of the population remained relatively stable within the dominant flora with time since several of the more common 0-serotype/biotype combinations were isolated from more than half of the eight slurry samples examined.
