Resumo: | The stories of food poisoning from staphylococci, mainly by S. aureus, are frequently associates to the ingestion of food with 100 ng of enterotoxin/g or mL. The production of enterotoxin using staphylococci is strongly associated with the production of coagulase. In this paper, milk samples of 51 milk properties in Londrina (RS) and 50 in Pelotas had been evaluated. All the 101 samples had presented counts of coagulase positive staphylococci (CPS). From 552 colonies studied, 256 were CPS where 60% of the colonies were typical in Baird Parker agar and, from 296 coagulase negative staphylococcus (CNS), in mean, 60% were atypical colonies. Due to the enterotoxigenic capacity, were tested 109 CPS, being 5,5% (6) positive and 18 CNS where 1 (5,5%) were positive. The frequency of CPS EEA (5,5%) producer was similar of the CNS. There is a wide milk contamination with CPS, where, a big part (40%) of the atypical colonies is coagulase producers. |

A produção de enterotoxina pelos estafilococos está associada fortemente à produção de coagulase. Neste trabalho foram avaliadas amostras de leite de 51 propriedades leiteiras em Londrina (RS) e 50 em Pelotas. Todas as 101 amostras apresentaram contagens de estafilococos coagulase positivos (ECP). Das 552 colônias avaliadas, 256 foram coagulase positivas e destas cerca de 60% eram típicas no àgar Baird Parker e, em média, 60% do total de 296 estafilococos coagulase negativos (ECN) eram colônias atípicas. Quanto à capacidade enterotoxigênica, testou-se 109 colônias ECP, sendo 5,5% (6) positivas e 18 ECN, sendo 1 (5,5%) positiva. Assim, a freqüência de ECN produtores de EEA (5,5%) foi semelhante a dos ECP. Conclui-se que há extensa contaminação do leite cru por ECP, sendo grande parte (40%) das colônias atípicas produtoras de coagulase.UEL2006-07-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/252210.5433/1679-0359.2006v27n4p639Semina: Ciências Agrárias; Vol. 27 No. 4 (2006); 639-646Semina: Ciências Agrárias; v. 27 n. 4 (2006); 639-6461679-03591676-546Xreponame:Semina.
