Implication

Laboratory study reveals atypical enterotoxigenic cocci share genetic and enzymatic traits with Staphylococcus aureus, indicating they represent variants or mutants of the species.

Key Points

To evaluate the taxonomic and genetic relationship between atypical coagulase-negative enterotoxigenic cocci and Staphylococcus aureus.
Evaluated eight coagulase-negative enterotoxigenic strains and one weakly coagulase-positive strain isolated from diverse sources, including food poisoning outbreaks.
Characterized isolates by measuring DNA buoyant density to establish guanine-plus-cytosine content, serotyping enterotoxins, and profiling biochemical traits such as lysostaphin susceptibility and enzyme activity.
Strains produced enterotoxin types C (seven isolates, singly or combined), B, A, or D, with DNA guanine-plus-cytosine content ranging from 32.7% to 37.6%.
All strains fermented glucose, grew anaerobically, produced catalase, and synthesized heat-stable nuclease, while five were sensitive to lysostaphin and produced acid from mannitol.
No strain matched standard profiles for S. aureus, S. epidermidis, or S. saprophyticus, supporting their designation as variants or mutants of S. aureus.
