AI Article Synopsis
- * The research revealed a high prevalence (89.2%) of antibiotic resistance genes, with the most common being detected in 75% of the samples, and notable resistance to several antibiotics like penicillin and ampicillin.
- * The presence of toxigenic genes and substantial antibiotic resistance in strains found in raw milk poses significant public health and food safety risks.
Article Abstract
This study investigated the toxigenic genes and antimicrobial resistance profiles of strains isolated from 260 raw milk samples collected from dairy farms in Türkiye. The results indicated that 60.7% of staphylococcal enterotoxin genes (, , , , , , , , , , and ) and 21.4% of the and genes were positive, with most enterotoxin-positive samples carrying more than one gene. The , , , , , , and genes were not identified in any samples. The prevalence of antibiotic resistance genes (, , , , , , , /, , , , , and ) was high at 89.2%, with being the most frequently detected gene (75%). The gene was present in 14.2% of samples, while was detected in 78.5%. Nevertheless, the was not identified. Disinfectant resistance genes (A/B, , , ) were detected in 21.4% of the samples. The results of the disk diffusion test showed that 64.2% of strains were resistant to penicillin G and ampicillin, with additional resistance found for cefoxitin, teicoplanin, levofloxacin, norfloxacin, and other antibiotics. These findings highlight a significant public health and food safety risk associated with raw milk due to the presence of strains with toxigenic genes and high antimicrobial resistance.

is a common etiological factor of hospital infections, which, in extreme cases, can lead to the death of patients. Most strains belonging to this bacterium species synthesize very dangerous toxins: toxin A (TcdA) and B (TcdB) and binary toxin (CDT). The aim of this study was to assess the suitability of agarose gel electrophoresis separation of multiplex PCR amplicons to investigate the toxinogenic potential of strains.

The toxigenic strains secrete tilymicin and tilivalline enterotoxins, which cause antibiotic-associated hemorrhagic colitis. Both enterotoxins are non-ribosomal peptides synthesized by enzymes encoded in two divergent operons clustered in a pathogenicity island. The transcriptional regulator Lrp (eucine-responsive egulatory rotein) controls the expression of several bacterial genes involved in virulence.

Background: sequence type (ST) 81, mainly associated with ribotype (RT) 369, is a TcdA-negative and TcdB-positive genotype and a common ST found in China. Furthermore, ST81 strains are reported with highest resistance rates to many antimicrobial agents. However, given the potential for ST81 transmission, research into the epidemiological characteristics of this type of ST remain limited.

Rationale: Plasmids can play a major role in the survival of pathogenic bacteria. Plasmids are acquired through horizontal gene transfer resulting in their spread across various strains, species and genera of bacteria. Colicins are bacterial protein toxins expressed by plasmid genes and released against co-located bacterial competitors.
