Identification of Genes Encoding Classical Staphylococcal Enterotoxins in Staphylococcus Aureus Isolated from Raw Milk
This study describes a multiplex PCR assay developed for the detection of Staphylococcus aureus enterotoxin types: SEA, SEB, SEC, SED, and SEE presented in the literature as classical. The method was then used to analyse the presence of genes encoding these enterotoxins in .S aureus strains isolated from raw milk. A total of 237 raw milk samples were used in the study and 77 (32.5%) of them wer...
متن کاملHigh incidence of enterotoxin D producing Staphylococcus spp. in Brazilian cow's raw milk and its relation with coagulase and thermonuclease enzymes.
In this study, the enterotoxigenic potential of Staphylococcus strains (n = 574) isolated from raw milk samples (n = 140) was determined for their capacity to produce staphylococcal enterotoxins. In addition, the relationship between the presence of enterotoxins, coagulase, and thermonuclease (Tnase) was assessed. The results showed that 19% of Staphylococcus was enterotoxigenic, being able to ...
متن کاملEnterotoxin gene profiles among Staphylococcus aureus isolated from raw milk
Milk is considered a nutritious food because it contains several important nutrients including proteins and vitamins. Conversely, it can be a vehicle for several pathogenic bacteria such as Staphylococcus aureus. This study aimed to analyze the frequency of genes encoding the nine Staphylococcal enterotoxins (SEs) and enterotoxin gene profiles in S. aureus isolates derived from raw bovine milk....
متن کاملProduction of Enterotoxins by Staphylococcus Aureus Isolated from Sheep Milk
The production of staphylococcal enterotoxin A and staphylococcal enterotoxin B was investigated in S. aureus isolates obtained from milk of clinically healthy sheep. In comparison with valid standard (up to 1. 10 CFU. ml), the S. aureus counts were higher in 36 of the total number of 46 positive milk samples (ranging from 1.2. 10 to 8.2. 10 CFU. ml). Six (13.0%) of the 46 isolates were enterot...
متن کاملAntibiotic Resistance and Detection of femA Gene in Staphylococcus Aureus Isolates from Raw Milk
ABSTRACT Background and Objective: Antibiotic-resistant Staphylococcus aureus strains have become a problem in treatment of infections caused by S. aureus. This study aimed to evaluate antibiotic resistance in S. aureus isolates from raw milk and detect femA gene in these isolates, as a confirmatory test for identification of S. aureus species. ...
