Summary: The study investigated the prevalence and antimicrobial resistance of Salmonella enterica serovar Enteritidis in broiler chickens in Shandong Province, China. It found that S. Enteritidis was the predominant serovar with high antimicrobial resistance rates to several antibiotics. Multidrug resistance, particularly to fluoroquinolone, showed an increasing trend from 2013 to 2018. This study provides updated information on antimicrobial resistance data and risk assessment for Salmonella Enteritidis in broiler chickens in Shandong Province, which can be valuable for future surveillance activities to ensure chicken supply safety.

Summary: Cooked battered products like nuggets and sausages are popular street food in Malaysia, but there is a lack of prevalence data for non-typhoidal Salmonella enterica serovars Enteritidis and Typhimurium (NTS) contaminations in these foods, leading to concerns about foodborne outbreaks. This study examined the prevalence of antibiotic-resistant NTS in battered foods and assessed their survival in simulated gastric fluid (SGF) and microwave heating.

Summary: This study aimed to detect virulent Salmonella serovars, including those producing ESBLs, isolated from broiler chickens and humans. The results showed a high prevalence of Salmonella in both broiler and human samples, with the most predominant serovars being S. enteritidis and S. typhimurium. The study also identified the presence of multidrug resistant (MDR) isolates and resistance genes, including ESBLs, in both chicken and human samples.

Summary: Using the One-Health strategy, we studied the temporal and spatial dynamics of dominant serovars of Salmonella enterica in China. We found that Salmonella Typhimurium was the most common serovar causing human infection in China. The proportion of various serovars, including Typhimurium, showed an increasing trend from 2006 to 2019.

Summary: This study investigated the efficacy of a killed Salmonella Chitosan nanoparticle (CNP) vaccine on broilers. The results showed that the CNP vaccine significantly enhanced the immune response to Salmonella antigens in poultry, and reduced gut permeability and Salmonella count after infection. The study suggests that the CNP vaccine is a viable alternative to conventional Salmonella poultry vaccines.

Summary: This study investigated the association among the host genome, the gut microbiome, and S. Pullorum infection in chickens. The results showed that the gut microbial structure is altered in S. Pullorum-infected chickens, and the diversity and abundance of the gut microbiota differ significantly between the offspring from S. Pullorum-positive and S. Pullorum-negative parent chickens, with heritable gut microbiota detected in the offspring. Host genetic variants were linked to microbial diversity and individual gut microbes, and pathogens Pelomonas and Brevundimonas showed high heritability in S. Pullorum-infected chickens.

Summary: The study identified the transmission of ESC resistance determinants in E. coli and Salmonella within the same chicken, with most E. coli isolates carrying bla(CTX-M-55) or bla(CMY-2) and most Salmonella isolates carrying bla(CTX-M-15). Two broiler chicken farms were found to harbor both bla(CMY-2)- and bla(CTX-M-15)-harboring E. coli and Salmonella isolates.

Summary: This study evaluated an alternative strategy using phage-based treatment against Salmonella isolated from broiler production, showing a high prevalence of Salmonella spp. in bedding samples from broiler farms in eastern and southern Thailand. Multiple Salmonella phages were isolated from various water sources and found to effectively lyse several Salmonella serovars, leading to the conclusion that a phage cocktail can be an effective biocontrol method against Salmonella in broiler production and MDR serovars.

Summary: The study found that on-farm anaerobic digestion can reduce the abundance of enteric bacteria, antibiotic resistance-associated gene targets, and the horizontal transfer potential of ESBL genes. Most gene targets were more abundant in raw manure, but some resistance gene targets were more abundant in digested samples.

Summary: This study evaluated the effects of long-term and repeated exposure to macrolide antibiotics on the diversity of soil bacterial community, resistome, and mobilome. At unrealistically high concentrations, macrolide antibiotics altered the overall diversity of resistome and mobilome, enriching for antibiotic resistance genes and mobile genetic elements of concern to human health. However, at realistic antibiotic concentrations, no effect on these endpoints was observed, suggesting that current biosolids land management practices are unlikely to pose a risk to human health due to macrolide antibiotic contamination alone.

Summary: The increase in antimicrobial resistance is a major concern for human and animal health, especially when resistance affects extended-spectrum cephalosporins, commonly used to treat serious infections. This study investigated the diversity and distribution of extended-spectrum cephalosporin-resistant Escherichia coli in dairy manure in Southern Ontario, Canada, and characterized their resistance plasmids. The results highlighted the importance of manure treatment in reducing the levels of antimicrobial-resistant bacteria and emphasized the potential dissemination of resistance genes through environmentally applied manure.

Summary: It is generally believed that antibiotics provide producing bacteria with a competitive advantage by inhibiting or killing neighboring microorganisms. However, modeling studies have shown that the concentrations of antibiotics near single producing cells are not high enough to have inhibitory effects, while concentrations around aggregates of cells can reach inhibitory levels.

Summary: Commercial cheese brines can be a reservoir for salt-tolerant pathogens. This study found that the addition of hydrogen peroxide can effectively reduce the population of L. monocytogenes in cheese brines, especially at higher temperatures and salt concentrations. The presence of indigenous microorganisms may neutralize the effect of hydrogen peroxide.
