Spread of bla(CTX-M-type) and bla(PER-2) beta-lactamase genes in clinical isolates from Bolivian hospitals.
To assess the prevalence and types of genes encoding extended-spectrum beta-lactamases (ESBLs) in clinical isolates of Enterobacteriaceae, Pseudomonas aeruginosa and Acinetobacter spp. from Bolivia. ⋯ This is the first study on ESBL-producing strains in Bolivia and it reveals a high prevalence of bla(CTX-M) genes. The PER-2 enzyme was less prevalent, but its gene was detected in several species, including P. aeruginosa, which is consistent with horizontal transfer.

Prescribing of antibiotics, often in the empirical setting, frequently falls on training-grade or junior doctors, who are often the least experienced in this. Indeed, improving the knowledge base of training-grade doctors or senior medical students through education has been identified as one of the key measures to improve antibiotic prescribing behaviour. ⋯ Overall, there was a significant improvement in doctors' understanding of sepsis and knowledge of the source of information that they utilized to select the antibiotic of choice, although the majority did not acknowledge the price difference between intravenous and oral forms of antibiotics.
