Male gender and healthcare facility residency are risk factors for ESBL-producer infections among patients with community-onset bacteremic UTIs. Patients with bacteremic UTIs caused by ESBL-EK also have prolonged hospital stays and higher antibiotic costs. Early detection of ESBLs and appropriate antibiotic coverage are likely to shorten hospital stays and reduce medical costs.
K. ohmeri should not be regarded as a contaminant of blood cultures. Favorable outcomes for this potentially life-threatening infection are promoted by the removal of indwelling catheters; furthermore, outcomes are associated with optimal antifungal regimens, especially voriconazole and echinocandins.
There are few reports of invasive infections caused by Brevundimonas vesicularis. We report two cases of B. vesicularis bacteremia confirmed by culture and 16S rRNA sequence analysis with highly variable sensitivity to broad-spectrum antibiotics. Initial empiric therapy with anti-pseudomonal antibiotics plus trimethoprim-sulfamethoxazole for hospital-acquired B. vesicularis infections should be considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
