<p><strong>Introduction</strong>: bacterial infections are a public health problem. Besides, the emergence of strains resistant to antimicrobials has<br />contributed to the search for new alternatives, such for the terpenes with antimicrobial potential. <strong>Objectives</strong>: the objective of this<br />study was to determine the possible interaction of isolated monoterpenes (-)-Carveol, Geraniol, Citronellol, α-terpineol, R-(-) Carvone,<br />(-)-Menthol, Linalool, D-Dihydrocarvone, and (-)-Terpine-4-ol with conventional antimicrobials (Chloramphenicol, Minocycline,<br />Amoxicillin and Ciprofloxacin) when they are evaluated on Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis,<br />Escherichia coli and Pseudomonas aeruginosa strains. <strong>Methodology</strong>: the minimum inhibitory concentrations of these test drugs<br />were determined using the microdilution method. The Checkerboard method was used to assess the interactions, by determining<br />the fractional inhibitory concentration index (FIC index). <strong>Results</strong>: aamong the monoterpenes, only Carveol, Citronellol, and Geraniol<br />presented antimicrobial activity (MIC < 1024 μg/mL). They presented synergistic effects against Pseudomonas aeruginosa ATCC-9027<br />(FIC index ≤ 0.5) when in combination with Minocycline. <strong>Conclusion</strong>: this study contributes to the development of new approaches<br />to control bacterial resistance and to the possibility of discovering new drugs.</p>
Introduction: Laboratory diagnosis related to clinical microbiology is highly complex, due to subjectivity when interpreting the results. Among bacterial pathogens, those linked to the Staphylococcus genus are relevant from a clinical and epidemiological point of view. Aim: To review the literature relative to the main laboratory methods used for the isolation and identification of microorganisms of the genus Staphylococcus. Methodology: The study was based on a literature search between 2000 and 2020, in the BVS, PubMed, Scielo, ScienceDirect and CAPES Periodical databases. Regarding its laboratory diagnosis, microscopy is used by the Gram method to verify the bacterium’s morphology; novobiocin test, aiming to trace coagulase negative strains; use of biochemical tests, such as coagulase and catalase tests; identification through the use of selective and nonspecific culture media, such as blood agar (in which the hemolytic patterns of pathogens are observed), salty mannitol agar (specific to the species of Staphylococcus aureus) and DNAse agar (selective to S. aureus strains , S. intermedius and S. hyicus). Results: The Staphylococcus genus is of great clinical importance in the field of public health. Thus, the quality and speed of diagnosis are essential to promote measures to combat these pathogens, contributing to the well-being and survival of those affected.
Introdução: a meningite é uma infecção que afeta as membranas as quais revestem o encéfalo e a medula espinhal, sendo incluída na Lista Nacional de Doenças de Notificação Compulsória. Objetivo: investigar o perfil epidemiológico de acometidos por meningite noBrasil, entre os anos de 2010 a 2020. Metodologia: trata-se de um estudo epidemiológico, retrospectivo, analítico e documental, pelo qual as informações acerca dos casos confirmados no Brasil foram extraídas através do Departamento de Informática do Sistema Único de Saúde (DATASUS). Para análise estatística foi utilizado o software Statistical Package for Social Sciences (versão 20.0). Resultados: no período analisado, foram notificados 187.508 casos de meningite, sendo 2012 o ano com maior número de casos (11,6%). A região que apresentou o maior número de mortes foi sudeste (54,2%), possuindo São Paulo como o estado de maior número de notificações (41%). O perfil foi composto, predominantemente, por indivíduos do gênero masculino (59,1%), com faixa etária entre ≤1 a 9 anos (47%) e etiologia viral (45,5%). O método quimiocitológico foi o mais utilizado (60,9%), o qual os enfermos evoluíam a alta (75,8%). Além disso, a meningite bacteriana apresentou a maior taxa de mortalidade (1,8/100.000 habitantes), enquanto a meningococcemia a maior taxa de letalidade (36,7%). Houve associação estatística positiva entre as variáveis: número de óbitos e faixa etária, número de óbitos e gênero e, número de óbitos e etiologia. Conclusão: é essencial a adoção de políticas públicas com escopo às populações de risco, sendo esse estudo, profícuo na construção de tais projetos.
