Mobile genetic elements contribute to the emergence and spread of multidrug-resistant bacteria by enabling the horizontal transfer of acquired antibiotic resistance among different bacterial species and genera. This study characterizes the genetic backbone of in spp. and Klebsiella spp.

Antimicrobial use in animal husbandry is a major concern since it can favor an increase in antimicrobial resistance among farms. Herein, we aim to better understand and characterize the main resistome profiles in microbial communities found in pig farms.

Hospital-built environment colonization by healthcare-associated infections-related bacteria (HAIrB) and the interaction with their occupants have been studied to support more effective tools for HAI control. To investigate HAIrB dynamics and antimicrobial resistance (AMR) profile we carried out a 6-month surveillance program in a developing country public hospital, targeting patients, hospital environment, and healthcare workers, using culture-dependent and culture-independent 16S rRNA gene sequencing methods. The bacterial abundance in both approaches shows that the HAIrB group has important representativeness, with the taxa Enterobacteriaceae, , , , and widely dispersed and abundant over the time at the five different hospital units included in the survey.

However, in Pseudomonas aeruginosa chromosomal mutations are more frequently responsible for resistance to carbapenems than the acquisition of mobile elements harbouring carbapenemases genes. Indeed, although uncommon, KPC-2-producing P.

We hereby report microbiological and genomic characteristics of two -positive polymyxin-resistant isolates identified for the first time in community patients, in Santa Catarina, Southern Brazil. strains belonging to ST206 and ST354 and the resistome analysis revealed the presence of clinically important genes responsible for MDR profile.
