Abstract

de Carvalho MJ, Pimenta FC, Hayashida M, Gir E, da Silva AM, Barbosa CP et al. Prevalence of methicillin-resistant and methicillin-susceptible S. aureus in the saliva of health professionals. Clinics. 64(4):295-302. INTRODUCTION:S. aureus is one of the main agents of nosocomial infection and is sometimes difficult to treat with currently available active antimicrobials. PURPOSE: To analyze the prevalence of methicillin-susceptible S.aureus (MSSA) and methicillin-resistant S. aureus (MRSA) as well as the MRSA antimicrobial susceptibility profile isolated in the saliva of health professionals at a large public education hospital. MATERIALS AND METHODS:The project was approved by the research and ethics committee of the institution under study. Three samples of saliva from 340 health professionals were collected. The saliva analysis used to identify S. aureus was based on mannitol fermentation tests, catalase production, coagulase, DNAse, and lecithinase. In order to detect MRSA, samples were submitted to the disk diffusion test and the oxacillin agar screening test . In order to identify the minimum inhibitory concentration, the Etest® technique was used.

Colonization of nursing professionals by Staphylococcus aureus

“…Regarding the prevalence of MRSA, the highest was found in Curitiba (12.7%) (9) and the lowest was found in Santo André (4.1%) (15) . The results encountered in the present study, when compared to the others, proved to be of an intermediate value, i.e.…”

Prevalência de Staphylococcus Aureus Meticilina Resistente em Profissionais de Enfermagem

“…A meticilina e sua análoga, a oxacilina, são antimicrobianos rotineiramente utilizados em hospitais para o tratamento de infecções causadas por S. aureus (ATIQUE et al, 2012), logo, o Staphylococcus aureus demonstra que a sua virulência e capacidade de adquirir resistência aos agentes antimicrobianos resulta em um problema sério em todo o mundo (CARVALHO et al, 2009).…”

Prevalência de bastonetes Gram-negativos isolados da saliva de trabalhadores da saúde

“…Tal fato contribui para a ocorrência de contaminação cruzada, visto que estes trabalhadores atuam como reservatório e potenciais disseminadores de micro-organismos para o ambiente, para os clientes e para a comunidade hospitalar (1)(2)(3) .…”

“…Entretanto, além das mãos, a colonização de outros sítios anatômicos por agentes infecciosos também contribui para a transmissão cruzada de patógenos (3,(7)(8)(9) . (6,(14)(15) .…”
