“…It may be also involved in systemic infections [61,62]. The pathogen commonly found in acute and chronic infections of the hearing aid with both children [63,64] and adults [65,66]. reported that the implant-associated infection with S. aureus bacteria is developed in 15 out of 44 patients with prosthetic joints [74].…”

“…Recent studies have demonstrated that hemolysin also participates in the formation of the S. aureus biofilm (den Reijer et al, 2016). The increasing prevalence of multidrug-resistant S. aureus strains within hospital and community environments further increases the dangers of S. aureus and poses a serious challenge for clinical therapy (Voss and Doebbeling, 1995; Evangelista Sde and de Oliveira, 2015). …”

Staphylococcus aureus is a common pathogen causing both hospital and community-acquired infections. Hemolysin is one of the important virulence factors for S. aureus and causes the typical β-hemolytic phenotype which is called complete hemolytic phenotype as well. Recently, S. aureus with an incomplete hemolytic phenotype (SIHP) was isolated from clinical samples. To study the microbiologic characteristics of SIHP, the special hemolytic phenotype of SIHP was verified on the sheep blood agar plates supplied by different manufacturers. Expression of hemolysin genes hla, hlb, hlgC, and hld of SIHP was detected by qRT-PCR and it was showed that expression of hlb in SIHP was obviously increased compared to the control S. aureus strains with complete hemolytic phenotype (SCHP), while the expression of hla, hlgC, and hld in SIHP was significantly decreased. In addition, the α-hemolysin encoded by gene hla was decreased obviously in SIHP compared to SCHP by western blot. All 60 SIHP strains were identified to be the methicillin resistant S. aureus (MRSA), and moreover these SIHP strains all contains mecA gene. The virulence gene tst were all present in SIHP, and the intracellular survival ability of SIHP was much greater than that of the gene tst negative S. aureus. We also found that IL-2, IL-6, and IL-17A secreted in the supernatant of SIHP infected macrophages increased significantly compared to tst negative control strains infected ones. MLST analysis showed that all of SIHP strains were classified into ST5 clone. To our knowledge, this study firstly showed that SIHP strains are a kind of methicillin resistant strains which express β-hemolysin highly and possess a potential high virulence, and it was suggested that SIHP should be paid more attention in hospital.

“…16,17 Assim como nesse estudo, a alta prevalência de S. aureus também foi encontrada em trabalho realizado em uma UTI adulto, onde o índice isolado nas superfícies foi de 76,2%. 18 Este achado é relevante, pois o S. aureus pode causar diversas patologias, situação que se agrava ainda mais em paciente imumodeprimidos, podendo causar septicemia, endocardites, infecções associadas com dispositivos intravasculares e pneumonias.…”

Justificativa e Objetivos:As infecções hospitalares em pediatria vêm apresentando índices elevados, devido à susceptibilidade dos recém nascidos em adquirir doenças e ao aparecimento de bactérias resistentes. Estes fatores, somados ao risco da contaminação do ambiente hospitalar por microrganismos de importância epidemiológica, podem ocasionar um processo de contaminação cruzada.O objetivo deste trabalho foi avaliar a contaminação ambiental da Unidade de Terapia Intensiva Pediátrica de um Hospital no Rio Grande do Sul - Brasil. Métodos: Estudo transversal, realizado durante o mês de março de 2011. Foram utilizados 20 swabs estéreis umedecidos com solução fisiológica,friccionados nas superfícies de estetoscópios, monitores, respiradores, incubadoras, mesas e suporte de tomada elétrica. Para identificação dos microrganismos foram utilizados testes bioquímicos. O teste de susceptibilidade aos antimicrobianos foi realizado utilizando o método de Etest para vancomicina e de Kirby Bauer para os demais antibióticos. Resultados: Foram identificados 27 microrganismos: Staphylococcus aureus (51,9%), Streptococcus spp. (18,5%), Staphylococcus spp. (14,8%), Escherichia coli (3,7%), Klebsiella oxytoca (3,7%), Acinetobacter lwoffii (3,7%) e Enterococcus spp. (3,7%). Destes, 78,6% dos isolados de S. aureus foram resistentes a oxacilina e,100% dos Staphylococcus spp. foram resistentes ao mesmo antibiótico. Foi encontrado multirresistência para o isolado de A. lowffii. Conclusão:Os microrganismos isolados apresentam riscos tanto para saúde do paciente quanto do profissional de saúde. Intervenções de prevenção e higienização são necessárias, visando reeducação da equipe profissional. Somente através da conscientização de todos os profissionais se conseguirá reduzir a disseminação de microrganismos através de contaminação cruzada.
