Genomic epidemiology of third-generation cephalosporin-resistant from Argentinian pig and dairy farms reveals animal-specific patterns of co-resistance and resistance mechanisms.

Unlabelled: Control measures are being introduced globally to reduce the prevalence of antibiotic resistance (ABR) in bacteria on farms. However, little is known about the current prevalence and molecular ecology of ABR in bacterial species with the potential to be key opportunistic human pathogens, such as on South American farms. Working with 30 dairy cattle farms and 40 pig farms across two provinces in central-eastern Argentina, we report a comprehensive genomic analysis of third-generation cephalosporin-resistant (3GC-R) , which were recovered from 34.

Detection of in nasal and laryngeal swab specimens in endemically infected pig herds.

Background: Apparently, laryngeal swabs (LS) are more sensitive than nasal swabs (NS) and allow earlier detection of by PCR. However, antecedents about the compared detection of with NS and LS in growing pigs, from naturally infected herds, are lacking in the literature. Thus, this study compared the PCR detection of from NS and LS in pigs of various ages.
