This article reviews recent clinical evidence for the treatment of methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. Vancomycin remains the initial antibiotic of choice for the treatment of patients with MRSA bacteremia and endocarditis due to isolates with vancomycin minimum inhibitory concentration ≤2 μg/mL, whereas daptomycin is an effective alternative, and ceftaroline seems pr...

BACKGROUND The incidence of Pseudomonas aeruginosa bacteremia has not been defined in a population-based investigation. METHODS We performed a retrospective, population-based incidence study using resources of the Rochester Epidemiology Project of Olmsted County, Minnesota. We identified all Olmsted County residents with P. aeruginosa bacteremia between January 1, 1997, and December 31, 2006,...

Klebsiella pneumoniae bacteremia associated with a Tesio hemodialysis catheter To the Editor: Catheter-associated bacteremia is a serious complication of temporary hemodialysis vascular access. Bacteremia is the second leading cause of death in hemodialysis patients. Infectious episodes are also the leading cause for untimely catheter removal and for morbidity in dialysis patients. In a study o...

Endotoxemia is undetectable for up to 60% of cases of bacteremia caused by gram-negative (GN) species, a discordance attributed to the limitations of the Limulus assay for endotoxemia. The lipid A structure of the endotoxin molecule is critical for the sensing of GN bacteria by the host immune system although not so for sensing by the Limulus assay. The lipid A structure of commensal Enterobact...

BACKGROUND Previous prospective studies of bacteremia in African children with severe malaria have mainly included children with cerebral malaria, and no study has examined the impact of human immunodeficiency virus (HIV) infection. We examined the prevalence and etiology of bacteremia and the impact of HIV infection on bacteremia in Malawian children with severe malaria, as well as the impact ...

BACKGROUND Advances in Aeromonas taxonomy have led to the reclassification of aeromonads. Hereon, we aimed to re-evaluate the characteristics of Aeromonas bacteremia, including those of a novel species, Aeromonas dhakensis. METHODOLOGY/PRINCIPAL FINDINGS A retrospective study of monomicrobial Aeromonas bacteremia at a medical center in southern Taiwan from 2004-2011 was conducted. Species ide...

In the nonneutropenic host, bacteremia due to Clostridium tertium is rare and of unclear significance. We describe a patient in whom presentation with Clostridium tertium bacteremia was the harbinger of Crohn's disease. In order to understand the significance of C. tertium bacteremia in neutropenic and nonneutropenic hosts, we review all 32 cases of C. tertium bacteremia that occurred at Duke U...

Of 500 hospital-onset Staphylococcus aureus bacteremia events (58% methicillin-susceptible S. aureus [MSSA]; 42% methicillin-resistant S. aureus [MRSA]), we found no significant differences in S. aureus bacteremia rates between medium-sized and large hospitals. However, the proportion of S. aureus bacteremia caused by MSSA was greater in medium-sized hospitals and did not correlate with MRSA ba...

Clostridium species are anaerobic Gram-positive rods that can cause a broad range of invasive infections in humans, including myonecrosis and bacteremia. Importantly, clostridial bacteremia is frequently associated with underlying medical conditions, such as colonic malignancy. Characterizing Clostridium spp. and understanding their associated clinical disease spectrum are paramount to provide ...

944 Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 13, No. 6, June 2007 Septic shock developed in 4 (14.8%) of the 27 neutropenic patients with A. baumannii–associated bacteremia, and 2 (7.4%) of the 27 died (Table). However, we did not fi nd a statistically signifi cant association between death among patients with bacteremia caused by MDR A. baumanni (1 death) compared with death among...
