إنجليزي. The ability of Streptococcus strains derived from more representative clinical forms to produce suilysin has been evaluated. The results have been compared with those of tonsillar strains derived from regularly slaughtered pigs. 258 strains on 637 (40.5%) are positive. Considering the different clinical forms, positivity is distributed, in decreasing order, among septicaemia (73%), meningitis (61%), arthritis (50%), pneumonia (39%) and enteritis (50%). The isolates from tonsillar localisation result instead positive in 30% of the cases. The toxigenic ability is greater in the acute clinical forms as meningitis, septicaemia and arthritis, where Streptococcus is isolated in purity and its presence is related to clinic symptoms and lesions

E' stata valutata la capacita' suilisinica di streptococchi provenienti dalle forme cliniche piu' rappresentative, confrontando i risultati ottenuti con quelli degli isolamenti tonsillari da suini regolarmente macellati. Sono risultati positivi 258 ceppi su 637, pari al 40,5%. Considerando le diverse forme cliniche, le positivita' sono distribuite, in ordine decrescente, tra setticemie (73%), meningiti (61%), artriti (50%), polmoniti (39%) ed enteriti (50%); gli isolamenti dalle localizzazioni tonsillari sono invece risultati positivi nel 30% dei casi. La capacita' tossigena e' maggiore nelle forme cliniche acute, come meningite, setticemia e artrite, dove il microrganismo e' isolato in purezza e la sua presenza e' facilmente correlabile alle manifestazioni anatomo-cliniche
