Introduction: Infections caused by methicillin-resistant Staphylococcus aureus (MRSA) have become common in hospitals and the community environment, and this wide resistance has limited patient treatment. Clindamycin (CL) represents an important alternative therapy for infections caused by S. aureus. Antimicrobial susceptibility testing using standard methods may not detect inducible CL resistance. This study was performed to detect the phenotypes of resistance to macrolides-lincosamides-streptogramin B (MLS B ) antibiotics, including CL, in clinical samples of S. aureus from patients at a tertiary hospital in Santa Maria, State of Rio Grande do Sul, Brazil. Methods: One hundred and forty clinical isolates were submitted to the disk diffusion induction test (D-test) with an erythromycin (ER) disk positioned at a distance of 20mm from a CL disk. The results were interpreted according to the recommendations of the Clinical and Laboratory Standards Institute (CLSI). Results: In this study, 29 (20.7%) of the 140 S. aureus samples were resistant to methicillin (MRSA), and 111 (79.3%) were susceptible to methicillin (MSSA). The constitutive resistance phenotype (cMLS B ) was observed in 20 (14.3%) MRSA samples and in 5 (3.6%) MSSA samples, whereas the inducible resistance phenotype (iMLS B ) was observed in 3 (2.1%) MRSA samples and in 8 (5.8%) MSSA samples. Conclusions: The D-test is essential for detecting the iMLS B phenotype because the early identifi cation of this phenotype allows clinicians to choose an appropriate treatment for patients. Furthermore, this test is simple, easy to perform and inexpensive.

Objetivo: Avaliar o perfil clínico e molecular das infecções causadas por bactérias Staphylococcus aureus resistentes nas unidades de terapia intensiva do Brasil. Metodologia: O presente estudo trata-se de uma revisão integrativa de literatura sobre o tema proposto, realizada nas bases de dados PubMed\Medline, Scielo e Lilacs. Utilizando-se os descritores “staphylococcus aureus “AND “Resistant “. Incluiu-se pesquisas e revisões e exluiu-se cartas aos editores e resenhas. Resultados: O aumento da resistência das bactérias aos antimicrobianos é objeto de preocupação cada vez maior, principalmente em ambientes altamente seletivos como as UTI’s, devido ao uso indiscriminado de antibióticos e excesso de procedimentos, que fazem profissionais da saúde carrear microrganismos. Pesquisas revelam que 70% dos microrganismos são resistentes a pelo menos um antimicrobiano. Nomeia-se ESKAPES o grupo dessas bactérias, dentre as quais está a Staphylococcus aureus, objeto deste estudo. Colonizadora de pele e fossa nasofaríngea, gram-positiva, apresenta alta prevalência nas unidades de terapia intensiva e alta virulência. Além de fácil disseminação, sua capacidade de adaptação possui diversos focos, desenvolvendo resistência à quase todas as classes de antibióticos, chegando ao limite das alternativas de tratamento. Conclusão: O Staphylococcus aureus é resistente à quase todas as classes de antibióticos disponíveis. Faz-se necessário mais estudos sobre este patógeno e formas de disseminação, a fim de evitar maiores danos principalmente aos pacientes das UTI’s.

“…It is estimated that 30% of the United States population is colonized by Staphylococcus aureus, and 1.5% of this bacterium is methicillin-resistant Staphylococcus aureus (MRSA). In Brazil, there are no systematized data showing colonization rates in the general population, and some studies were developed in specific populations (for example, in patients seen at a dermatology clinic) indicate the prevalence of Staphylococcus aureus ranging from 15.5% to 68.79% Paula;Mrochen et al, 2020).…”

With an increasing demand for gyms, especially during summer, the risk of contamination rises despite preventive care. In many sports, exercising must require attention to hygiene, mainly due to great chances of contracting diseases. Staphylococcus aureus has widely spread caused by its ability to express various virulence factors, which can cause diseases ranging from simple to most severe infections as a pathogen. This paper investigates the incidence of Staphylococcus aureus in equipment from a gym of physical activities in Alfenas-MG and identifies the appropriate level about the importance of cleaning equipment. In this study, three collections were carried out per equipment in different places, at three times; totaled 54 samples. Staphylococcus aureus was identified by sowing in Mannitol Salt Agar, medium coloration and colonial morphology, catalase, and coagulase tests. Twenty-nine samples obtained growth from the sowings, being positive for gram staining, catalase, and coagulase. In samples with micro-organisms (53.70%) and correspondents (50%), gym-goers did not clean the equipment, and the others (50%) only used the individual towel. Therefore, the measures that can decrease the incidence of micro-organisms, particularly Staphylococcus aureus, are disinfecting with 70% alcohol and disposable paper before and after manipulating equipment in a gym.
