Species differentiation is essential as the sensitivity of different species to chemical reagents, antibiotics, and virulence factors may be diverse. This study aimed to mine new molecular targets for the detection of Cronobacter strains at the species level. Using a bioinformatics a ...
... The use of antibiotics as veterinary drugs is a significant practice to maintain the well-being of farmed animals. Meanwhile, ethical violations committed during the application of the drugs by animal producers have become a major reason for contamination of animal products which in turn causes serious side effects on public health after consumption. The side effects could be severe, long-lasting, ...

Abstract:
... The serotype, antimicrobial resistance, and molecular typing of 843 Salmonella isolates recovered from diarrheic patients in Guangxi Zhuang Autonomous Region (Guangxi), China from 2014 to 2017 were investigated. Among these 843 isolates, a total of 67 Salmonella serotypes and four un-typable isolates were detected by the slide agglutination method. The most prevalence serotype was Salmonella 1,4,[ ...
... The increased resistance of campylobacters to antibiotics required the identification and isolation of novel antimicrobials able to inhibit its virulence, to cause less or no resistance and display no host toxicity. Acquiring all this knowledge was only possible through a better understanding of their antibacterial potency and of the biological mechanisms involved attenuating the bacterial virulen ...
... 3-Phenyllactic acid (PLA) and slightly acid electrolyzed water (SAEW) are effective antimicrobial agents with broad-spectrum activity. The combined effects of PLA and SAEW on the inactivation of Klebsiella oxytoca planktonic and biofilm cells were evaluated in this study. The K. oxytoca K6 planktonic and biofilm cells were treated with PLA (0.5%, 1% and 2%), SAEW (30 and 60 mg/L), 0.5% PLA plus 30 ...
... Antibiotics residue in food is a big threat to human being health and life. Development of simple and fast detection techniques targeting residual antibiotics are urgently needed for food safety. Many analytical techniques have been used for the detection of antibiotic residues in food. Among these analytical techniques, microfluidic analysis gains increasing attention due to its advantages of low ...
... Salmonellosis is a prevalent food poisoning disease caused by Salmonella spp. that affects millions of people throughout the world. Contamination of chicken meat and processing equipment with Salmonella is a major issue in the food industry. Therefore, it is necessary to study not only food but also food contact surfaces [plastic (PLA) and rubber gloves (RG)] that can cause cross-contamination dur ...
