“…In the present work, staphylococcal enterotoxins (SEs) also investigated, since enterotoxigenic S. aureus is considered the second most prevalent pathogen in foodborne diseases in Brazil 31 . The most prevalent gene was the SEA toxin, commonly related to cases of intoxication, corresponding to 75% of outbreaks, and also correlated with human food contamination 32 .…”

Introduction: Contamination of cell phones can contribute to the dissemination of pathogens in the community and/or hospital environment. Objective: To characterize Staphylococcus aureus strains isolated from cell phones of university students. Methods: Samples were collected from 100 cell phones. Detection of genes associated with virulence factors such as biofilm formation (icaA and icaD), enterotoxins production (SEA, SEB, SEC, and SED), and resistance to methicillin (mecA and mecC) was performed in S. aureus isolates by PCR. Typing mecA gene performed by multiplex PCR. Susceptibility to antimicrobials and biofilm formation rate also evaluated by using disk diffusion test and crystal violet staining. Results: S. aureus was present in 40% of the total samples and about 70% of them belonged to Nursing students. Of the isolates, 85% presented resistance to penicillin and 50% were classified as moderate biofilm producers. In addition, 92.5% of isolates contained the gene icaA and 60% of the gene icaD. Approximately 25% of the isolates presented the mecA gene. Typing of the mecA gene showed the presence of staphylococcal chromosome cassette SCCmec I and c III respectively in 20% and 10% of the isolates. 70% of the samples could not be typed by the technique. Regarding the enterotoxins, the most prevalent gene was SEA (30%) followed by the SEC gene (2.5%). The presence of SED and SEB genes not observed in any of the isolates. Conclusion: The cleaning and periodic disinfection of cell phones can contribute to the reduction of the risk of nosocomial infection.

A pandemia causada pelo coronavírus disparou a possibilidade da crise em diversos segmentos, sobretudo com a adoção do isolamento social, principal ação para o controle da doença infectocontagiosa. O presente estudo justifica-se pela preocupação em relação às tendências do desenvolvimento sustentável no pós-pandemia da COVID-19, no estado do Rio Grande do Sul. A mensuração do grau de sustentabilidade dos municípios segue a tese de que, quanto maior for o grau de sustentabilidade dos municípios, menor o impacto da pandemia, e maiores os recursos para restabelecer o equilíbrio. O objetivo da pesquisa é analisar a distribuição espacial do potencial para a sustentabilidade no pós-pandemia do COVID-19, nos municípios do Rio Grande do Sul, a fim de gerar um mapa de risco sobre os municípios com menor e maior potencial para a sustentabilidade no pós-pandemia. Foi realizada uma análise ecológica, aplicado o instrumento Barômetro da Sustentabilidade, realizada a distribuição e análise espacial, utilizando o cálculo do Índice de Moran. Os resultados apresentam a distribuição e análise espacial do número de casos confirmados, coeficiente de incidência e quantitativo de óbitos pela COVID-19 no Estado. A espacialidade pode explicar o coeficiente de incidência da doença. Foi estimado o potencial para a sustentabilidade e gerado o mapa de risco do potencial para a sustentabilidade, no pós-pandemia do COVID-19, para os municípios do Rio Grande do Sul. Spatial analysis and distribution of the potential for sustainability in the post-pandemic of COVID-19 in the municipalities of Rio Grande do Sul A B S T R A C TThe pandemic caused by the coronavirus triggered the possibility of the crisis in several segments, especially with the adoption of social isolation, the main action for the control of the infectious disease, therefore, the present study is justified by the concern in relation to the trends of sustainable development in the post-pandemic of COVID-19, in the state of Rio Grande do Sul. Measuring the degree of sustainability of the municipalities follows the thesis that the greater the degree of sustainability of the municipalities, the less the impact of the pandemic, and the greater the resources to restore balance. The objective of the research is to analyze the spatial distribution of the potential for sustainability in the post-pandemic of COVID-19, in the municipalities of Rio Grande do Sul, in order to generate a risk map with less and greater potential for sustainability in the post- pandemic. This study was carried out by means of an ecological analysis and application of the Barometer of sustainability, later the distribution and spatial analysis was carried out by means of the Moran Index. The spatial analysis, performed by calculating the Moran Index, showed significant spatial independence for confirmed cases (I = 0.058; p = 0.024) and deaths (I = 0.032; p = 0.039), and a significant, albeit weak, correlation. for the incidence coefficient (I = 0.234; p = 0.001) of COVID-19. Spatiality does not explain the distribution of cases and deaths. However, when taking into account the population size of the municipalities, in relation to the number of cases, expressed by the incidence coefficient, the spatial aggregation gains merit. The potential for sustainability was estimated and the risk map of the potential for sustainability was generated, in the post-pandemic of COVID-19, for the municipalities of Rio Grande do Sul.Keywords: Moran index; Sustainability Barometer; Sustainability Index; coronavirus; Pandemic.

“…The median Bacillus cereus outbreak incubation periods have been reported to be up to 4 h in a study that covered 16 years [159], but knowledge of the mechanistic basis of spore germination and outgrowth is still a difficult challenge [160]. In some countries, Bacillus cereus has been proposed as the main causal agent of foodborne outbreaks [161] and outbreaks around the world are still common especially after celebration parties [162] and in schools, as exemplified in previous reports [163][164][165]. The proper identification of the Bacillus species in a beverage from a region or location will ensure a targeted and effective control.…”

Traditional and Artisanal Beverages in Nigeria: Microbial Diversity and Safety Issues

et al. 2020

View full text Add to dashboard Cite

A review of up to 90 articles on the microorganisms associated with important artisanal or traditional beverages in Nigeria was carried out. This resulted in an overview of the prevalent microorganisms associated with soymilk, nono (fermented cow milk), tiger nut milk, yoghurt, kunu, zobo, palm wine and the local beers pito and brukutu. The bacteria genera, namely Bacillus, Escherichia, Lactobacillus, Staphylococcus, and Streptococcus, were detected in all nine beverages. On the contrary, this survey resulted in finding that the genera Saccharomyces, Aspergillus, Candida, and Penicillium were the eukaryotic microorganisms isolated in all beverages. The occurrence of fungal isolates, which can be responsible for producing mycotoxins, is a concern and shows the need for post-production tests. Overall, there is a low prevalence of bacteria associated with hygiene, especially the Escherichia genus in alcoholic beverages such as palm wine, pito and burukutu, which may be due both to a low acidity and high ethanol content. However, the prevalence of hygiene indicator genera was higher in nonalcoholic drinks, probably because of incorrect practices during processing. The magnitude of the production and sales of unregulated local beverages in Nigeria has reached the stage where significant regulation and food safety standards are required to safeguard public health. An opportunity exists to monitor and characterize the microbial flora of the artisanal beverages using molecular methods at all stages of production and storage.
