Within patient genetic diversity of bla harboring Klebsiella pneumoniae in a Colombian hospital and identification of a new NTE platform.

Resistance to carbapenems in Klebsiella pneumoniae has been mostly related with the worldwide dissemination of KPC, largely due to the pandemic clones belonging to the complex clonal (CC) 258. To unravel bla post-endemic clinical impact, here we describe clinical characteristics of 68 patients from a high complexity hospital, and the molecular and genetic characteristics of their 139 bla-K. pneumoniae (KPC-Kp) isolates.

In vitro activity of tedizolid and other comparator drugs in methicillin-resistant Staphylococcus aureus isolates in skin and soft tissue infections in seven Colombian hospitals.

Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) causes severe skin and soft tissue infections in hospitals and, more recently, in the community. Tedizolid is a new second-generation oxazolidinone derivative having greater in vitro potency than linezolid against this type of microorganism. Objectives: To evaluate the antimicrobial activity of tedizolid and other comparator antibiotics in MRSA isolates causing skin and soft tissue infections in Colombian hospitals.
