This study was to estimate the prevalence and characteristics of Staphylococcus aureus from 1,850 retail meat products in China during July 2011 June 2016. The samples were collected covering most provincial capitals China, including 604 raw meat, 601 quick-frozen 645 ready-to-eat meat. Using qualitative quantitative methods, all 39 cities had S. aureus-positive samples, detected 35.0% (647/1,850) samples. levels showed that MPN value majority positive ranged 0.3 100 MPN/g. Twenty-four...
Bacillus cereus is widely distributed in different food products and can cause a variety of symptoms associated with poisoning. Since ready-to-eat (RTE) foods are not commonly sterilized by heat treatment before consumption, B. contamination may severe safety problems. In this study, we investigated the prevalence RTE samples from regions China evaluated levels bacterial contamination, antibiotic resistance, virulence gene distribution, genetic polymorphisms these isolates. Of tested retail...
Bacillus cereus is a common and important food-borne pathogen that can be found in various food products. Due to low-temperature sterilization for short period of time, pasteurization not sufficient complete elimination B. milk, thereby cause severe economic loss safety problems. It therefore paramount importance perform risk assessment pasteurized milk. In this study, we isolated from milk samples different regions China, evaluated the contamination situation, existence virulence genes,...
The prevalence and levels of Listeria monocytogenes in retail raw foods covering most provincial capitals China were studied with testing 1036 samples vegetables, edible mushrooms, meat, aquatic products quick-frozen from September 2012 to January 2014. total was 20.0% (207/1036), the probable number (MPN) values 65.7% positive ranged 0.3 110 MPN/g. Geographical differences observed this survey, results both qualitative quantitative methods indicated that North higher than those South China....
Increasing data indicate that insects serve as major reservoirs and vectors of viruses, which account for the continuously increasing ecological burden infectious disease outbreaks. Uncovering hidden diversity viruses in will further understanding evolutionary perspectives emergence insect-associated virus diseases. In this study, we queried transcriptome sequencing (RNA-Seq) from more than 600 species across 32 insect orders dwelling different habitats recovered 1,213 RNA were recapitulated...
Methicillin-resistant Staphylococcus aureus (MRSA) is an emerging pathogen that difficult to treat due the multiresistance of bacteria upon infection. From 2011 2016, 1581 S. strains were isolated from 4300 samples retail foods covering most provincial capitals in China. To determine prevalence food-related MRSA and its genetic background China, antibiotic resistance, staphylococcal toxin genes, cassette chromosome mec (SCCmec) typing, spa-typing MLST carried out this study. In total, 108...
Salmonella remains the leading cause of reported bacterial foodborne disease in China. Meat products obtained from livestock are recognized as one major sources human salmonellosis; however, there is a lack comprehensive, quantitative data concerning contamination these foods. Therefore, objectives this study were to investigate prevalence, load, and antimicrobial resistance profiles various serovars retail meat across whole Between July 2011 June 2016, total 807 product samples collected 39...
Salmonella is a widely distributed foodborne pathogen. The use of phages as biocontrol agents has recently gained significant interest. Because the genus high diversity, efforts are necessary to identify lytic focusing on different serovars. Here, five were isolated from soil samples, and vB_SalP_TR2 was selected novel phage with potential against host serovar Albany, well other tested serovars, including Corvallis, Newport, Kottbus, Istanbul. Morphological analyses demonstrated that belongs...
In this study, we characterized the β-lactamase genes of cephalosporin-resistant Enterobacteriaceae isolated from retail foods in China. Of 1024 isolates recovered raw meat products, aquatic vegetables, retail-level ready-to-eat (RTE) foods, frozen and mushrooms 2011 to 2014, 164 (16.0%) showed cefotaxime (CTX) and/or ceftazidime (CAZ) cephalosporin resistance, 96 (9.4%) extended-spectrum (ESBL) phenotype. More than 30% were resistant all antimicrobial agents except carbapenems (MEM 3.1% IPM...
Listeria monocytogenes is a globally notoriousfoodborne pathogen. This study aimed to qualitatively and quantitatively detect L. from meat products in China establish their virulence profiles population diversity. From 1212 product samples, 362 (29.9%) were positive for monocytogenes. Serogroup analysis showed that the most prevalent serogroup of was I.1 (1/2a-3a), which accounted 45.0% (123/458) total, followed by I.2 (1/2c-3c) comprised 26.9%, II.1 (4b-4d-4e) 4.8%, II.2 (1/2b-3b-7) 23.3%....
Eighty Listeria monocytogenes isolates were obtained from Chinese retail ready-to-eat (RTE) food and previously characterized with serotyping antibiotic susceptibility tests. The aim of this study was to characterize the subtype virulence potential these L. by multilocus sequence typing (MLST), virulence-associate genes, epidemic clones (ECs) analysis important factor: internalin A (inlA). result MLST revealed that belonged 14 different types (STs). With exception four new STs (ST804, ST805,...
Listeria monocytogenes, an intracellular foodborne pathogen, is capable of causing listeriosis, such as meningitis, meningoencephalitis, and abortion. In recent years, the occurrence monocytogenes in edible mushroom products has been reported several countries. There are no guidelines for qualitative quantitative detection L. China. Therefore, this study aimed to investigate prevalence contamination level mushrooms Chinese markets determine antibiotic resistance sequence types (STs) these...
