Abstract
ESPINOSA, Ivette et al. IDENTIFICATION OF syl GENE IN CUBAN ISOLATES OF Streptococcus suis FROM SWINE USING THE POLYMERASE CHAIN REACTION (PCR). Rev Salud Anim. [online]. 2010, vol.32, n.1, pp.48-53. ISSN 0253-570X.
Streptococcus suis is a facultative anaerobic coccus considered an important agent associated to meningitis, arthritis, endocarditis and pneumonia. In this work, the isolation of S. suis from different clinical conditions such as pneumonia, joint and tonsil in asymptomatic animals was carried out. Fourteen strains of S. suis were identified: 11 from lungs, 2 from abscess and 1 from tonsils. The strains showed different pattern of biochemistry test. The syl gene codifying for suylisin was detected by PCR only in 5 strains, four coming from lung and one from tonsil. However, in the isolations from abscess and associated to arthritis, the presence of this gene was not detected showing a similar behaviour to the strains from North America (syl -) associated to invasive disease.
