This assessment reveals high antibiotic resistance and virulence genes in Salmonella Typhimurium isolates in South Africa, suggesting urgent public health strategies.
Key Points
High antibiotic resistance was found in Salmonella Typhimurium, with 86.8% resistant to ciprofloxacin and 69.0% to ceftriaxone.
The study identified prevalent virulence genes, with 100% of isolates containing invA, highlighting potential public health threats.
Genetic analysis also revealed multiple plasmids, with the most common being 90 kb detected in 71.3% of isolates.
Multidrug resistance was observed, with isolates showing resistance to up to 11 different antibiotics, emphasizing the need for surveillance.
