Evaluation Of Methods for the Determination of O and K Antigens of an O2:K1(L) Strain of Escherichia Coli

Journal of Medical Microbiology (1977)

J.R. Deb E.G. Harry

SUMMARY Tests made on ten colonies from a strain of Escherichia coli 02:K1 demonstrated that bacterial agglutination tests were reliable for identifying the O antigen of serogroup 02 but were unreliable for identifying the Kl antigen. The granular nature of K agglutination was not a reliable characteristic of the L type of K antigen. In contrast, indirect haemagglutination, immunodiffusion and immunoelectrophoresis tests with bacterial extracts gave consistent results with all colonies. The polysaccharide Kl antigen formed a long anodic precipitation line with two peaks, indicating its heterogenous nature, and partial fusion of this line with the O-antigen precipitation line suggested the presence of common serological determinants. In addition, a heat-labile protein antigen, possibly another K antigen, was identified by indirect haemagglutination tests and may have produced a short anodic precipitation line. The results also showed that the Kl antigen was still produced after storage of a culture for 12 years on Dorset-egg medium.

The Influence of Temperature and Moisture on the Disinfecting Activity of Methyl Bromide on Infected Poultry Litter

Journal of Applied Bacteriology (1973)

E.G. Harry W. Burns Brown Gwen Goodship

ABSTRACT. At 25°, exposure of finely sieved poultry house litter for 20 h to methyl bromide (MeBr) gas at concentrations of 10–120 mg/l, i.e. concentration‐time (CT) products of 200–2400 mg h/l, resulted in a marked reduction in the number of bacteria present in terms of Salmonella typhimurium, Escherichia coli and micrococci. The activity of the gas was affected adversely by a reduction in temperature and by its application to litter of a high moisture content. Except with wet litter, a reduction of >99% of the Salm. typhimurium present resulted from exposure at 25° to gas concentrations as low as 10 mg/l (CT product, 200 mg h/l) and it was undetected in samples exposed to 40 mg/l at 25° (CT product, 800 mg h/l) or 80 mg/l at 10° (CT product, 1600 mg h/l). The significance of reductions of this order, in terms of the infectivity of the litter to chicks subsequently reared on it, is discussed. Escherichia Coli showed a susceptibility similar to that of Salm. typhimurium but micrococci were considerably more resistant.
