“…Studies from different countries have indicated that food handlers, owing to their 20–30 % carriage rate, have been one of the major sources of food contamination with S. aureus (Lory 2014 ; Van Belkum et al 2009 ). In this study 20 % of isolates were identified as S. aureus and the percentage rate were higher in nasal cavity isolates (57 %) than mouth (23 %) and hand (20 %) ones.…”

“…It is widely distributed in nature and is commonly found in the nose, throat, hair and skin of humans and animals. Approximately 20–30 % of healthy people carry this microorganism (Lory 2014 ; Van Belkum et al 2009 ). However, S. aureus is a potentially dangerous pathogen causing a variety of localized or invasive diseases, as well as food poisoning.…”

The aim of this study was determine carriage rate and methicillin resistance of Staphylococcus aureus among food handlers. Samples were collected by swabbing the mouth, nasal cavity and hands of food workers. The isolation of S. aureus was performed using a culture method and verified by using a genetic method (PCR). The presence of mecA gene was analysed by PCR. The fourteen antimicrobial disks were also used to determine antimicrobial susceptibility of S. aureus. The 56 out of 282 isolates were identified as S. aureus. It is found that 10 workers out of 28 carried S. aureus in their nasal cavity while 4 and 3 workers out of 21 carriered S. aureus in mouth and hands respectively. None of the isolates carried mecA genes and also their antibacterial susceptibility test for methicillin resistance, using cefoxitin (30 µg), shown that all the isolates was susceptible to methicillin. In conclusion, the results of the present study indicated that the prevalence of antibiotic resistance of S. aureus strains isolated from food handlers was low. However carriage rate of S. aureus among food handlers was quite high.

“…Macrococcus, a gram-positive bacterium closely related to Staphylococcus, was often found in animal skin samples and their meat products (Sae et al, 2010). Previous researchers concluded that Macrococcus has nothing to do with human or animal disease (Lory, 2014), but a strain of Macrococcus causing high mortality has been separated from commercial chickens in China (Li et al, 2018). Meanwhile, Macrococcus was also one of the main microorganisms responsible for chicken spoilage (Arthur et al, 2004).…”

Panxian ham, a traditional Chinese dry-cured ham, is protected by national geographical indication. Similar to other fermented foods, the microbial population of dry-cured ham is pivotal to taste and flavor formation. This study aimed to establish the relationship between microorganisms and metabolites during the spontaneous fermentation of Panxian ham. Multivariate analysis based on metabolomics data revealed that continuous metabolic changes occurred during the entire fermentation process, with the most significant changes occurring in the initial stage of ripening. Thirty-one significantly different metabolites (SDMs) were identified as discriminant factor, and pathway analysis suggested that these metabolites were involved in 30 pathways, including alanine, aspartate, and glutamate metabolism; glycine, serine, and threonine metabolism; and arginine and proline metabolism. Microbial community analysis using the Illumina MiSeq platform indicated that the bacterial community was more complex than the fungal community, and their succession regulation differed during processing. At the genus level, 11 bacteria and five fungi were identified as core microbes, of which Staphylococcus was the dominant bacteria and Debaryomyces and Aspergillus were the dominant fungi. Further, statistical redundancy analysis (RDA) indicated that Staphylococcus, Debaryomyces, and Chromohalobacter promoted the production of amino and fatty acids; Cobetia and Aspergillus were associated with sugar metabolism, and Kushneria, Penicillium, and Yamadazyma were closely related with organic acids. These findings provide fundamental knowledge regarding the metabolically active microorganisms in Panxian ham, helping industrial processors to develop effective strategies for standardizing quality parameters.

“…Some notable examples within the families Streptococcaceae , Staphylococcaceae , Micrococcaceae , and Corynebacteriaceae can be human skin–associated taxa, which supports the idea that these contaminants are introduced by researchers as they prepared the samplers. 42–45 However, OTUs from the families Sphingomonadaceae , Xanthomonadaceae , and Rhodobacteraceae , which are typically of environmental origin, were also in these categories. 46–48 To be conservative, the OTUs in Categories B and C should also be removed from the data set because they are known to be at least equally prevalent in the closed sampler as in the open sampler.…”

Dispersal of airborne microorganisms is an important ecological process, resulting in the distribution of bacteria to all habitats on Earth. Investigation of this process is limited by the ability to collect uncontaminated high-altitude microbial samples for use with next-generation sequencing approaches. Here, we describe the design of a Remote Airborne Microbial Passive sampling system. Troubleshooting experiments demonstrate that the samplers collect adequate DNA for bacterial 16S rRNA (ribosomal RNA) amplicon-based Mi-Seq sequencing at 2 and 150 m from the ground. When samplers are closed, they retain only a low number of sequences, and may be used as a negative control. We also demonstrate that the optimal amount of collection dishes to include in the sampler is 8, and that freezing collection dishes at −80°C is an alternative to immediate DNA extraction. Samplers may be used to address a variety of ecological and human health-related questions.
