[Sensitivity of Salmonellae isolated from poultry to bacteriophage O1].
Studied were a total of 200 bacterial strains that agglutinated with the group B, C, D and E Salmonella sera. The organisms were isolated from viscera (liver, gallbladder, spleen, ovaries, and heart) and bone marrow from dead birds, from embryos, eggs, and washings from hatcheries, etc. in 1982-1985 in the district of Stara Zagora. It was found that the strains behaved biochemically as typical Salmonellae. Serologically typed of group B were 40 strains (S. typhimurium--34, and S. lagos--6); of group C--61 strains (S. oranienburg--38, S. isangi--7, S. montevideo--4, Salmonella II 6.7:gmst: 1.5--5, S. thompson--2, and S. newport--5); of group D--89 strains (S. gallinarum--57, S. gallinarum var. duisburg--23, S. pullorum--1, and S, enteritidis--8); and of group E--8 strains (S. senftenberg--4, S. anatum--4). Two of the strains were in the R form. Sensitive to the phage proved 89 +/- 5.7 per cent of the strains including the two R-form ones and those that were resistant of group C (S. oranienburg--5.4 per cent) and of group D (S. gallinarum--23 per cent, and S. gallinarum var. duisburg--26.1 per cent). The high sensitivity to the phage substantiated the phage identification of the strains as an adjunct, supplementary method in the complex diagnostics of diseases of a Salmonella etiology after the preliminarily determined phage for the respective region was made known.
