| Popis: | S. aureus has become a public health problem, due to the difficulty of treating infections caused by methicillin-resistant S. aureus (MRSA). The purpose of this research was to determine the production of enterotoxins A, B, C and D and the production of biofilm in clinical isolates of MRSA. Fifty MRSA strains isolated from different types of clinical samples were studied. Detection of enterotoxins was carried out using the technique of reversed phase agglutination, while biofilm production was studied through two tests: Congo red agar and the microplate cell culture method. Enterotoxin production was observed in 9 strains (18%); enterotoxin D (64%) was the most prevalent, followed by B (27%) and A (9%). A significant association was shown between enterotoxin production capacity and the type of sample that came from the strain. Biofilm production was found in 30% and 98% of the strains using the Congo red Agar and microplate cell culture methods, respectively. A correlation of both trials was observed in only 15 strains (30%). It was shown that the microplate cell culture method is more effective for detecting biofilm production in S. aureus strains. |
