Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen not only in nosocomial infections, but also in community-associated infections. The aim of this study was to evaluate the impacts of methicillin resistance on mortality, length of hospitalization, and hospital costs via propensity score matching in S. aureus bacteremia. ⋯ This study indicates that MRSA bacteremia is not associated with higher risks of mortality or hospital costs. It is, however, associated with a substantial increase in the length of hospital stay as compared to MSSA bacteremia. This information may help clinicians and policymakers derive methods to control the impacts of MRSA infection.

The genus Myroides comprises aerobic, yellow-pigmented, non-motile, non-fermenting gram-negative rods formerly classified as Flavobacterium odoratum. Members of the genus are widely distributed in the environment, especially in water, and usually behave as low-grade opportunistic pathogens, having been found to cause urinary tract infection, endocarditis, ventriculitis, and cutaneous infections in severely immunocompromised patients. ⋯ To our knowledge, this is the first description of life-threatening infection caused by this organism in an immunocompetent host. We have also reviewed the medical literature on the genus Myroides.

Reports on patients with European Lyme borreliosis in whom borreliae were isolated from the blood are rare and nearly exclusively limited to those with solitary or multiple erythema migrans. Here we report on patients with other manifestations of Lyme borreliosis in whom borreliae were isolated from their blood. ⋯ In European patients with Lyme borreliosis, borreliae can be cultured from the blood not only early in the course of the disease but also occasionally later during disease progression.
