title: [R and S-streptococcal infections in swine].
abstract: Some 115 R- and 143 S-streptococcal strains were isolated from 258 pigs that had died or been killed for disease, between 1969 and 1973. They were cultured and biochemically tested for sensitivity to chemotherapeutics. All R- and S-strains were of normal sensitivity to penicillin and, with few exceptions, to chloramphenicol and oxytetracycline as well. Most of the strains caused primary Sc.-infection, such as septicaemia, leptomeningitis, endocarditis, and arthritis. R-Sc.-infections were contracted mainly by store pigs and animals in advenced age, while S-Sc.-infections affected mainly piglets.
