RESUMO
Corynebacterium striatum has been described as a pathogen in immunocompromised patients; however, correctly identifying Corynebacterium spp. is often difficult, and cases of cellulitis caused by C. striatum are only rarely reported. We herein describe a case of cellulitis and bacteremia due to C. striatum identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry. Antimicrobial susceptibility testing was performed using the Strepto-Haemo Supplement method, and vancomycin was replaced by a narrow-spectrum oral amoxicillin.

We examined the results of surveillance of extended-spectrum ß-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae, which are pathogens known to cause nosocomial outbreaks, at a comprehensive cancer center in Japan over a 5-year period. We found that the admission prevalence and the incidence of ESBL-producing E coli increased during the study period, in contrast with ESBL-producing K pneumoniae, in which the parameters remained low throughout the study period.

Extrapulmonary tuberculosis (TB) can be infectious when diagnostic or therapeutic procedures are performed on infected lesions. We retrospectively describe infection control and evaluate isolation failure rates during the manipulation of active extrapulmonary TB lesions at a comprehensive cancer center over a 5-year period. Among patients with a high suspicion of cancer, extrapulmonary TB was not suspected, and airborne precautions often were not used when manipulating infected lesions.
