[Dynamics of the types of carrier state and their relationship to the phage group characteristics of pathogenic staphylococci].
A total of 305 persons belonging to the medical staff of a hospital surgery unit were subjected to multiple examinations during period of up to 8 years. 2,354 staphylococcal strains isolated from these subjects were studied, and the following types of carrier state were determined: constant (23.6 +/- 2.43%), intermittent (57.4 +/- 2.83%), resident (7.9 +/- 1.54%), and the stable absence of carrier state (11.1 +/- 1.60%). An increase in the number of examinations and the terms of observation resulted in a regular increase in the number of intermittent carriers at the expense of constant carriers and persons not identified as carriers. Against this background resident carriers constituted a relatively more stable group. Carrier states of the resident type were connected with staphyloccci belonging to various phage groups without pronounced differences in the frequency with which any of the phage groups occurred.
