Abstract
A new subspecies of Staphylococcus hominis described by Kloos et al. in 1998
and named S. hominis subsp. novobiosepticus (SHN) has been implicated in
nosocomial outbreaks. Multidrug resistance, including resistance to novobiocin
and oxacillin, is a particularly important feature of SHN. In our institute, we
encountered 13 cases of S. hominis subsp. hominis in cancer patients with
septicemia, of which seven were methicillin resistant. The isolates were identifi ed
by VITEKĀ® 2 compact automated system, using GP REF 21342 identifi cation card
and antimicrobial susceptibility testing card P-628. The biochemical reactions
and antibiotic susceptibility pattern of the seven methicillin-resistant isolates
were re-analyzed and patient details were re-checked to fi nally identify them as
SHN. The increasing number of cases reporting isolation of SHN from biological
specimens point to potential virulence and clinical importance of this bacterium.
