“…Hajek and Horak (1978) confirmed this specificity; strains from human, porcine, bovine, ovine and leporine sources being generally refractile to this phage set, as were the strains from animal sources described as processed poultry in terms of cultural characteristics (Harry, 1967a, b;Shimizu, 1968;Hajek and Marsalek, 1971;Devriese et al, 1972;Sato et al, 1972;Kusch, 1977;Gibbs et al, 1978a). Witte et al (1977) defined Staph. aureus variety gallinae (a biotype frequently isolated from beak swabs, synovitis and dermonecrotic lesions) by this method, and by susceptibility to an experimental phage.…”
