[Small-colony variants of Staphylococcus aureus: Usefulness of various test for diagnosis and susceptibility study].
BACKGROUND
Small colony variants of Staphylococcus aureus (SCVSA) are a sub-population with special features.


METHODS
The phenotypic features and antibiotic susceptibility of four clinical isolates SCVSA were studied.


RESULTS
Colonies grew in the usual culture media, except in Mueller Hinton. All isolates were resistant to ciprofloxacin and co-trimoxazole.


CONCLUSIONS
As SCVSA are isolated with low frequency, it is necessary to determine the optimal methods for their identification and antibiotic susceptibility study.
