Mammalian skin is the largest organ of the body and serves as a barrier to protect the body against chemical, mechanical and pathogenic insults as well as water loss. The epidermis is formed from the primitive ectoderm into a multilayered stratified epithelium, consisting of basal, spinous, granular and outermost cornified...
Staphylococcus aureus is a human pathogen capable of producing enterotoxins causing staphylococcal food poisoning, one of the most economically important foodborne diseases in the U.S. This pathogen may be introduced to pre-cooked tuna meat used for the production of canned tuna because significant manual handling occurs after cooking of the...
Previous studies have indicated that staphylococci have potential for use as indicators of water quality in swimming pool and other recreational waters. However, these organisms are not yet included in the official guidelines for recreational water quality promulgated by health authorities. The purpose of this study is to determine water...
The consumption of seafood in the United States has increased rapidly in recent years due to high quality protein and health benefits of seafood. Seafood can be a carrier for bacteria normally distributed in the marine environment and, in some cases, can be contaminated by human pathogens. Therefore, there is...
The effect of different oxygen atmospheres on growth, energy
charge and enterotoxin production of Staphylococcus aureus was
investigated. Three atmospheres, air, 5% oxygen in nitrogen and
20% oxygen in nitrogen, were tested on three strains producing
enterotoxins A, B and C. Colony forming units (CFU), dry weight,
dissolved oxygen, pH,...
Growth and enterotoxin production of Staphylococcus aureus in papain-treated beef and ham were studied. In addition to an untreated control, four treatments were used in the beef experiment including two levels of papain, a commercial tenderizer preparation, and commercially tenderized beef. Two levels of papain treatment and an untreated control...
