Soft Salt-Mannitol Agar–Cloxacillin Test: a Highly Specific Bedside Screening Test for Detection of Colonization with Methicillin-Resistant Staphylococcus aureus

Abstract: The early detection of colonization with methicillin-resistantStaphylococcus aureus (MRSA) of patients in intensive-care units is an essential step in the strategy for preventing MRSA epidemics. In this study, tubes containing soft salt-mannitol agar with cloxacillin (6 μg/ml) (SSMAC) were prepared for inoculation of clinical samples at patients’ bedsides by personnel of an intensive-care unit. A total of 1,914 swabs from different sample sites of 81 patients were dipped into SSMAC tubes, and after 24 h of inc… Show more

“…Infecções por MRSA freqüentemente são precedidas por um período de colonização (Mir et al, 1998;Safdar e Bradley, 2008). A triagem dos portadores de MRSA, melhor que simples identificação de pacientes infectados, tem se mostrado um componente importante das estratégias para controle dos surtos de infecção por MRSA, objetivando identificar pacientes portadores, que representam reservatórios ocultos deste microorganismo e então, adotar as precauções adequadas de isolamento (Francois et al, 2003;Levi et al, 2003;Ben-David et al,.…”

“…O nicho ecológico das cepas de Staphylococcus aureus são as narinas anteriores, região mais consistente em que este microorganismo pode ser isolado, e de onde pode ser disseminado para outras partes do organismo. Além disso, em muitos casos o tratamento das narinas anteriores, para eliminar a colonização nasal por Staphylococcus aureus, pode resultar no desaparecimento deste microorganismo em outras áreas do corpo (Kluitmans et al, 1997;Singh et al, 2003) A detecção precoce dos portadores de MRSA é essencial na investigação epidemiológica, na rápida implementação de isolamento dos pacientes colonizados (como o uso de avental e luvas para todo o contato direto), na decisão da terapêutica mais adequada e, finalmente para o controle e prevenção da disseminação dos isolados de MRSA (Mir et al, 1998;Francois et al, 2003;Safdar et al, 2003).…”

“…Staphylococcus aureus fermentam manitol formando colônias de características sugestivas deste microrganismo12 .Após o período de incubação, as colônias características foram repicadas, e isoladas em ágar-sangue de carneiro e incubadas a 35ºC por 24 horas. As colônias características obtidas em ágar sangue foram submetidas à coloração de Gram, e aos testes de catalase e DNAse para identificação fenotípica presuntiva13 . O controle de qualidade foi realizado utilizando-se a cepa ATCC ® 29213.Os isolados de Staphylococcus aureus identificados foram submetidos ao teste de triagem para detecção de resistência a oxacilina em ágar Mueller-Hinton contendo 4% de cloreto de sódio e 6 mg/L de oxacilina12 .…”
