infection with bacteremia and pneumonia.

species are non-fermentative Gram-negative coccobacilli that are ubiquitous in the environment. The archetype pathogen within the genus is , however, other species have the potential to cause human infection, especially in the hospital setting. We describe a patient with infection due to , a rare agent of human disease, which is often misidentified using biochemical methods.

Osteomyelitis and Bacteremia: Review of an Emerging Human Pathogen with an Expanding Spectrum of Disease.

Background: is an uncommon pathogen that may be misdiagnosed as viridans group streptococci. We review the literature of and report 2 clinical cases in which catalase-negative Gram-positive cocci resembling viridans group streptococci with elevated minimum inhibitory concentrations (MICs) to ceftriaxone were inconsistently identified phenotypically, with further molecular characterization and ultimate identification of .

Methods: Two clinical strains (from 2 obese women; 1 with a prosthetic hip infection and the other with bacteremia) were analyzed with standard identification methods, followed by matrix-assisted laser desorption ionization time-of-flight mass spectrometry, 16S recombinant ribonucleic acid (rRNA), and polymerase chain reaction (PCR).

Mycotic Thoracic Aortic Aneurysm After Intravesical Bacillus Calmette-Guérin Treatment.

Bacillus Calmette-Guérin (BCG) is widely used for the treatment of bladder cancer. We report a case of BCG-associated mycotic thoracic aortic aneurysm that was successfully treated with resection and antimycobacterial therapy.

The management of encephalitis: clinical practice guidelines by the Infectious Diseases Society of America.

Guidelines for the diagnosis and treatment of patients with encephalitis were prepared by an Expert Panel of the Infectious Diseases Society of America. The guidelines are intended for use by health care providers who care for patients with encephalitis. The guideline includes data on the epidemiology, clinical features, diagnosis, and treatment of many viral, bacterial, fungal, protozoal, and helminthic etiologies of encephalitis and provides information on when specific etiologic agents should be considered in individual patients with encephalitis.

Pichia ohmeri prosthetic valve endocarditis and review of the literature.

Fungal prosthetic valve endocarditis (PVE) is a serious complication of valve replacement surgery. We report the first case of documented Pichia ohmeri PVE in an immunocompetent man who was successfully treated with valve replacement and antifungal therapy with amphotericin B.
