“…The observation of a PFGE type with several representatives demonstrates the circulation of a single clone in the hospital and community. Previous studies have shown a higher diversity of S. warneri [ 40 ] and the dissemination of a single clone among health professionals [ 41 ]. The paucity of molecular epidemiology studies involving S. warneri hinders understanding the clonality of this species.…”

Coagulase-negative staphylococci (CoNS) may be considered contaminants when isolated from clinical specimens but may also be a cause of true infection. This study aimed to compare the clonality and SCCmec type of a collection of CoNS isolated from blood cultures of inpatients, nasal swabs of healthy individuals, and patients with chronic wounds, all from the same community, using SCCmec typing, pulsed-field gel electrophoresis (PFGE), and MLST. Staphylococcus epidermidis, exhibited high clonal diversity, but hospital and community clusters were observed. Nosocomial S. epidermidis clones belonged to sequence types ST2, ST6, and ST23. Some Staphylococcus haemolyticus clones were found to circulate in the hospital and community, while Staphylococcus saprophyticus exhibited very high clonal diversity. Staphylococcus lugdunensis, Staphylococcus warneri, and Staphylococcus capitis revealed several isolates belonging to the same clone in the hospital and community. The detection of different SCCmec types within the same cluster indicated high diversity. S. epidermidis was associated with SCCmec I and III, S. haemolyticus with I and II, S. capitis with type V, Staphylococcus hominis with mec complex type A and ccr1, and S. warneri and S. saprophyticus with SCCmec I. The generation of elements and new combinations of cassette genes were highly associated with CoNS isolates, suggesting that SCCmec may not be a good marker of clonality in these bacteria.

“…The indiscriminate use of these antibiotics has led to an increase in the occurrence of multidrug-resistant Staphylococcus. It was described for S. warneri, genes that can confer resistance to non-beta-lactam antibiotics, such as fluroquinolones and glycopeptides (vancomycin and teicoplanin) [10,14,15].…”

Coagulase-negative Staphylococcus warneri is an opportunistic pathogen that is capable of causing several infections, especially in patients with indwelling medical devices. Antimicrobial resistance is a global challenge for the treatment of infections caused by staphylococci. The most important virulence factor of CoNS is the biofilm-producing ability. This brief literature review discusses aspects of the antimicrobial resistance and virulence factors of the Staphylococcus warneri. Literature about the Staphylococcus warneri listed in PubMed between 2011 and 2021 was reviewed. Staphylococcus warneri is a part of the normal flora of the skin, especially the nares, head, legs, and arms. The importance of S. warneri as a modern-day pathogen is growing, as it has established itself as a successful nosocomial pathogen. S. warneri isolates from these infections are generally resistant to beta-lactam antimicrobial agents. The virulence of S. warneri have been suggested to be multifactorial, including adhesins, enzymes, extracellular toxins, capsule, iron uptake systems, virulence regulators and to adhere to produce biofilm, invade and destroy epithelial cells. The pathogenetic mechanisms of infections their mechanisms of bacterial persistence and evasion of the host’s immune system have not yet been clearly elucidated. Only with deeper studies, which will allow a more comprehensive understanding of its physiological characteristics, will it be possible to design effective strategies against S. warneri.

“…Os Estafilococos coagulase negativos fazem parte da microbiota residente das mãos e, embora sejam bem resistentes à remoção mecânica ou agentes químicos e não eliminados mesmo com uma higienização adequada, não oferecem riscos aos indivíduos saudáveis. Porém, podem causar infecções em pessoas imunologicamente comprometidas (SANTOS, 2002;SHAMOTO et al, 2015).…”

RESUMOA contaminação das mãos dos manipuladores está dentre os fatores que contribuem para o surgimento de doenças transmitidas por alimentos. O objetivo desse estudo foi avaliar as condições higiênico-sanitárias de manipuladores de uma unidade de alimentação e nutrição. A população de estudo foi composta por 30 manipuladores, avaliados por um checklist para levantamento observacional de higiene e por um questionário para obtenção de informações socioeconômicas e de hábitos de higiene. Foi realizada coleta microbiológica das mãos pelo método do saco estéril de polietileno, para avaliação da presença de coliformes totais e termotolerantes e contagem total de micro-organismos mesófilos aeróbios (UFC/mão) e Staphylococcus spp. Dentre os manipuladores avaliados, 56,7% eram do sexo feminino, com faixa etária predominante de 25 a 45 anos (66,7%), e nível de escolaridade médio completo (36,7%). A maioria dos itens avaliados no checklist teve grande porcentagem de adequação (85 a 95%), exceto o item "comportamento dos manipuladores" que obteve 14%. A maioria das amostras (93,3%) apresentou contagens de micro-organismos mesófilos aeróbios variando entre 4,5 x 10³ a 7,7 x 10 5 UFC/mão. Não foram detectados coliformes termotolerantes e Staphylococcus aureus em nenhuma das amostras e em 3,33% foi constatada a presença de coliformes totais. Foi constatado que os manipuladores avaliados faziam a higienização das mãos satisfatoriamente, pelo fato de não encontrar contaminação por micro-organismos epidemiologicamente importantes, recuperando a microbiota normal da pele. No entanto, observou-se que fatores relacionados ao comportamento dos manipuladores podem propiciar a contaminação dos alimentos durante a preparação. PALAVRAS-CHAVE: bactéria, mãos, serviço de alimentação. ABSTRACTThe contamination of the hands of manipulators are among the factors contributing to the appearance of foodborne diseases. The aim of this study was to evaluate the hygienic and sanitary conditions of food handlers at a food service in Uberlandia, MG, Brazil. The study population consisted of 30 food handlers, evaluated by a checklist for observational survey of hygiene, socio-economic and hygienic-sanitary information. Microbiological collection of hands by the method of sterile polyethylene bag also realized for evaluation of total and fecal coliforms and Staphylococcus spp. and aerobic mesophilic count. Among the evaluated handlers, 56.7% were female, with predominant age group 25-45 years (66.7%), and completed high school level (36.7%). Were observed higher adequacy rates (85-95%) in most health rules related to handlers. There was no presence of fecal coliform in any sample and presence of total coliforms in only 3.33% of the samples. The majority (93.3%) had counts of aerobic mesophilic ranging from 7.7 x 10 5 to 4.5 x 10³ CFU/hand. All samples were negative for Staphylococcus aureus species. The evaluated handlers have hand hygiene satisfactorily, because we not found contamination of epidemiologically important microorganisms, recovering the n...
