| Resumo: O objetivo deste trabalho foi apresentar uma revisão sobre a atividade do óleo essencial de Cinnamomum. cassia contra Staphylococcus aureus por meio de pesquisas nas bases Web of Science, Science Direct, Scopus, Lilacs e Medline. Para tanto, foram utilizados artigos que abordam os componentes químicos do óleo essencial (OE) de Cinnamomum cassia e sua atividade contra Staphylococcus aureus por meio de dados de diâmetro de inibição, Concentração Inibitória Mínima (CIM) e Concentração Bactericida Mínima (CBM), publicados entre 2011 a 2021. De 98 estudos identificados, 26 preencheram os critérios de inclusão. Os componentes químicos mais comumente encontrados no óleo essencial de C. cassia foram nesta ordem; cinamaldeído, na forma Trans/E, acetato de... |

| Twenty isolates from milk and goat cheese were confirmed asStaphylococcus aureus. These isolateswere characterised for phenotypic properties related to cell adhesion and for the presence ofenterotoxin production, intercellular adhesion andb-lactam resistance genes.Staphylococcus aur-eusL47 showed cell adhesion ability and positivity for thesec,sed,icaD,mecA andblaZgenes.Three antimicrobial compounds were tested singly or in pairs for growth control of strain L47: gal-lic acid (GA), nisin and essential oil (EO) ofCroton heliotropiifolius(velame). At 24 h, EO andEO+nisin showed higher inhibitory activity againstS. aureusL47 in goat milk. |

| There is a growing need to discover and develop alternative therapies for the treatment of mastitis caused by Staphylococcus spp. and multidrug-resistant bacterial infections. This study examined the chemical composition and antimicrobial potential of two propolis extracts (EPA and EPB) against seventy-seven isolates of Staphylococcus spp. obtained from subclinical bovine mastitis; three clinical strains of MRSA and two from clinical strains of S. aureus ATCC, identified as S. aureus ATCC 6538 and S. aureus ATCC 25923. The total phenolic content was determined by the Folin-Ciocalteau method, the total flavonoid content by the Dowd method and the phenolic profile was quantified by HPLC-DAD. The MBC values of the extracts were evaluated by broth... |

| Several different species of animals host staphylococci as normal microbiota. These animals can be a source of staphylococci zoonotic infections. People with routine or occupational exposure to infected/colonized animals are at risk of a potential transmission. Therefore, we aimed to investigate the presence of S. aureus and other staphylococci in camels used for recreational purposes as well as their antimicrobial resistance, virulence factors and genetic lineages. A total of 172 samples were collected from 86 healthy camels (nose and mouth) from different farms located in the Canary Islands, Spain. Antimicrobial susceptibility testing was performed against 14 antimicrobial agents. The presence of virulence genes was studied by PCR. Multilocus sequence... |
