چکیده

We describe a comprehensive detection system for 18 kinds of classical and newly described staphylococcal superantigenic toxin genes using four sets of multiplex PCR. Superantigenic toxin genotyping of Staphylococcus aureus for 69 food poisoning isolates and 97 healthy human nasal swab isolates revealed 32 superantigenic toxin genotypes and showed that many S. aureus isolates harbored multiple toxin genes. Analysis of the relationship between toxin genotypes and toxin genes encoding profiles of mobile genetic elements suggests its possible role in determining superantigenic toxin genotypes in S. aureus as combinations of toxin gene-encoding mobile genetic elements.

The Frequency of Staphylococcus aureus Classical Enterotoxin Genes in Raw Milk Samples in Zanjan, Iran

Background: Staphylococcus aureus is one of the major causes of food poisoning. Since milk is a nutritious source of proteins and vitamins, it could provide the optimal conditions for the growth of several bacterial pathogens, such as S. aureus. The present study aimed to assess the frequency of Staphylococcus aureus classical enterotoxin genes in raw milk samples in Zanjan, Iran. Methods: In ...

Use of multiplex PCR to detect classical and newly described pyrogenic toxin genes in staphylococcal isolates.

Staphylococcus aureus may contain one or more genes that encode a variety of immunomodulatory pyrogenic toxins (PTs), including the staphylococcal enterotoxins and toxic shock syndrome toxin (TSST). The PTs interact with several cellular targets to produce disease, such as food poisoning and toxic shock syndrome. At present, nine serologically distinct enterotoxins and one immunoreactive form o...
