“…The dominance of S. aureus enterotoxin A isolates in our present study has been also reported by other researchers for S. aureus recovered from food samples [36], human nasal carriers, and manually handled foods [37]. These observations might be indicative of contamination by workers' hands during processing [35].…”

“…On the other hand, we found that enterotoxin A was the toxin most commonly produced, followed by enterotoxin D, while enterotoxins B and C were the least common. Moreover, enterotoxin A is most often implicated in cases of staphylococcal food poisoning [35]. The dominance of S. aureus enterotoxin A isolates in our present study has been also reported by other researchers for S. aureus recovered from food samples [36], human nasal carriers, and manually handled foods [37].…”

Background: The aim of this research was to determine the prevalence of enterotoxin genes (sea-seo) in Coagulase Positive Staphylococcus (CPS) isolated from unpasteurized milk and milk products. These results were compared with the results obtained by using the detection kit SET-RPLA for the specific detection of staphylococcal enterotoxins (SEA-SED). Methodology: Eighty-one samples of milk and milk products were analyzed for the presence of Staphylococcus strains. Forty-six coagulase positive Staphylococcus isolates were tested for the production of staphylococcal enterotoxins (SEA-SED) by using the reversed passive latex agglutination method. The strains were also tested for the presence of se genes (sea-seo) by polymerase chain reaction. Results: One or more classical enterotoxin products (SEA-SED) were observed in 39% of the strains tested, while se genes were detected in 56.5%. SEA and sea were most commonly detected. For newly discovered se genes among CPS isolates tested in this study, except the seh gene which was revealed in four isolates (8.7 %), none of the strains harbored any of the other se genes (see, seg, sei, sej, sek, sel, sem, seo and sen). Conclusions: The finding of a pathogen such as staphylococci-producing SEs and containing se genes in milk and milk products in northern Morocco may indicate a problem for public health in this region. The presence of enterotoxigenic strains in food does not always necessarily mean that the toxin will be produced. For that reason, the combination of both methods (RPLA and PCR) is a guarantee for success in diagnostic analysis tests.

“…Many of the coagulase negative species are adapted solely to non-human hosts, therefore the entry of the CoNS species into human foods and enterotoxin production should not be ignored (Cunha et al, 2006;Jay et al, 2005). In this context the following species were isolated from beef meat (Shale, Lues, Venter, & Buys, 2005); S. aureus, Staphylococcus auricularis, S. capitis, Staphylococcus chromogens, S. cohnii subsp. cohnii, S. epidermidis, S. haemolyticus, S. hominis, S. intermedius, S. lentus, S. saprophyticus, S. sciuri, S. warneri, and S. xylosus.…”

“…S. xylosus is ubiquitous, can be found in various niches (12,25,28), and persists in soils and on surfaces (32). In addition to its ability to form biofilms (29), the ubiquity of S. xylosus might be explained by its ability to adapt to different environments.…”

Staphylococcus xylosus is a commensal of the skin of humans and animals and a ubiquitous bacterium naturally present in food. It is one of the major starter cultures used for meat fermentation, but a few strains could potentially be hazardous and are related to animal opportunistic infections. To better understand the genetic diversity of S. xylosus intraspecies, suppressive and subtractive hybridization (SSH) was carried out with the S. xylosus C2a strain, a commensal of human skin, used as the driver for three tester strains, S04002 used as a starter culture, S04009 isolated from cow mastitis, and 00-1747, responsible for mouse dermatitis. SSH revealed 122 tester-specific fragments corresponding to 149 open reading frames (ORFs). A large proportion of these ORFs resembled genes involved in specific metabolisms. Analysis of the distribution of the tester-specific fragments in 20 S. xylosus strains of various origins showed that the S. xylosus species could be divided into two clusters with one composed only of potentially hazardous strains. The genetic content diversity of this species is colocalized in a region near the origin of replication of the chromosome. This region of speciation previously observed in the Staphylococcus genus corresponded in S. xylosus species to a strain-specific region potentially implicated in ecological fitness.
