Emergence of multidrug-resistant Providencia rettgeri clone in food-producing animals: A public health threat

Carbapenemases encoding genes in Providencia rettgeri are a public health concern due to its resistance to antimicrobials, including polymyxins. Three multidrug-resistant (MDR) P. rettgeri isolates were found in swine and bovine stool samples in Brazil. Molecular analysis revealed ARGs conferring resistance to various antibiotics. The isolates were found to be part of the same clone, with phylogenetic analyses confirming its genomic relationship with P. rettgeri isolates from the USA and Malaysia.
