Abstract

Hospital or community acquired methicillin-resistant Staphylococcus aureus
(MRSA) have been described as an important public health problem, because
their resistance to beta-lactam and others antibiotics like macrolides, lincosamides,
clindamycin, aminoglycosides and sulfonamides. In this study we identified MRSA
prevalence at the Foundation of Tropical Dermatology and Venereology Alfredo da
Matta in Manaus, Brazil. The data were obtained from the culture and susceptibility
tests register book, at the clinical bacteriology laboratory, between September 1998
and October 2007. In 1,500 patients, 783 (52.2%) female and 717 (47.8%) male,
1,494 tests were processed. 239 S. aureus were isolated and 232 were submitted
to the susceptibility test, where 44,0% (102/232) presented oxacillin resistance
with 15.5% of MRSA prevalence. Oxacillin/methicillin resistance makes general
antibiotic therapy more complicated. The concern with the rates of prevalence or
incidence of infections caused by MSRA are justified by the eventual failure of the
infectious process therapy, most of it complicated by potential elevated morbidity
and mortality in adults as well as in children. Besides actions of control and
monitoring to minimize the risk of infections or colonization in health professionals
or patients, research is also necessary to characterize genotypically the hospital or
community origin of these microorganisms.
