Summary: Listeriosis is an important emerging zoonotic disease that affects human health through contaminated food consumption. The pooled prevalence of Listeria species in various food items in Ethiopia is 27%, with beef meat and ice cream being the highest prevalence foods. Awareness creation on food safety and regulatory implementation are strongly recommended.

Summary: The study revealed a high level of Salmonella contamination in duck farm environments in Korea. Implementation of cleaning and disinfection procedures, rodent control, and metal house walls significantly reduced the prevalence of Salmonella. Most Salmonella isolates showed antimicrobial resistance, indicating the importance of good biosecurity and hygiene practices in controlling contamination.

Summary: The prevalence of antimicrobial resistance (AMR) and virulence genes in Salmonella isolates from food-producing animals in Central China was assessed in this study. PCR analysis of isolates from swine, chicken, and cattle revealed the presence of multiple AMR and virulence genes. MLST analysis identified various sequence types, and bioinformatics analysis identified hub genes associated with AMR and virulence. This study provides valuable insights into the molecular mechanisms of AMR and pathogenicity of Salmonella.

Summary: This study aimed to investigate the epidemiology and antimicrobial resistance of S. Typhi and S. Paratyphi among enteric fever suspected patients in Bahir Dar, Ethiopia. The study found a 5.3% prevalence of EF, with 75% being S. Typhi isolates. High prevalence of bacterial resistance, especially multidrug resistance, was observed, highlighting the need for cautious antibiotic use in EF patient management.

Summary: This study aimed to assess the prevalence and characteristics of mcr-9-positive Salmonella isolated from retail food in China. The results showed that mcr-9-positive isolates were widely distributed in various provinces and food types in China, with S. Thompson being the most common serotype. Most of the mcr-9-positive isolates were susceptible to colistin, but exhibited multi-drug resistance. Many of these isolates also carried the ESBL-producing phenotype and co-carried bla(CTX-M-3) and bla(TEM-1) genes.

Summary: This study focuses on the detection of antimicrobial resistance and the presence of staphylococcal enterotoxin genes in Staphylococcus warneri strains. A total of 45 isolates were obtained from various meat samples and subjected to phenotypic and genotypic analysis. The results showed that resistance to ciprofloxacin and tetracycline was most common, and 22% of the isolates exhibited multi-resistance.

Summary: Wild birds pose a food safety risk by spreading foodborne pathogens through their feces. The viability of Salmonella in dried bird feces is low and is influenced by the presence of the Enterobacteriaceae family. Multiple serotypes of Salmonella were found in bird feces, including those commonly associated with human illness. Molecular identification of fecal samples confirmed the presence of Salmonella in 57 bird species, with 10 positive samples.

Summary: This study investigated antimicrobial resistance genes, pathogenicity mechanisms, and virulence factors in Salmonella Heidelberg E2 strain isolated from a chicken carcass in Southern Brazil using antimicrobial susceptibility testing and whole-genome sequencing. The strain belonged to ST15 and showed susceptibility to colistin but multidrug resistance to various antibiotics. Additionally, previously unreported genetic mutations were identified.

Summary: The study reported a high burden of bacterial vaginosis and aerobic vaginitis among women, with Enterococcus faecalis and Escherichia coli being common bacteria isolated. Additionally, antibiotics like vancomycin, cefoxitin, ciprofloxacin, clindamycin, gentamicin, and meropenem were found to have good action against the majority of bacteria isolates.

Summary: The study found that the pooled prevalence of non-typhoid Salmonella in human stools and animal origin foods in Ethiopia was 4.8% and 7.7% respectively, with high resistance rates (>72%) to ampicillin and tetracycline. Lower resistance rates were reported for ciprofloxacin and ceftriaxone. Antimicrobial stewardship efforts are needed to address this public health concern.

Summary: This study aimed to explore Salmonella prevalence and antimicrobial resistance characteristics in chicken embryo mortality in China. Salmonella Thompson and Salmonella Infantis were the most prevalent isolates, showing strong ampicillin resistance and multi-drug resistance. Most isolates carried bla(TEM) and qnrS genes, while Class 1 integrons were carried by a minority of isolates.

Summary: Salmonella and Escherichia coli are the most common infectious pathogens in poultry, showing high prevalence of antimicrobial resistance in broiler farms on the East Coast of Peninsular Malaysia. The findings suggest the need for enhanced monitoring and control measures to prevent the emergence of antimicrobial resistance, potentially attributed to the excessive use of antimicrobial agents by poultry farm owners.

Summary: This study investigated the prevalence and antimicrobial resistance patterns of Campylobacter spp. on chicken samples purchased from 50 local wet markets and supermarkets in central Thailand. High contamination rates and alarming levels of antimicrobial resistance were found in Campylobacter spp. isolated from retail chicken samples in Thailand, highlighting the necessity of interventions to reduce its prevalence in the country.

Summary: The study in Northwest Ethiopia described the population structure of MTBc strains among TB patients and evaluated the performance of culture isolation and MPT64-based speciation for Lineage 7. The predominant strains were East-African-Indian and Euro-American, with low prevalence of Ethiopia L7. Most MTBc isolates were susceptible to rifampicin and isoniazid, with limited multi-drug resistance detected.
