Pseudozyma aphidis is a heterobasidiomycetous yeast related to the smut fungi in the genus Ustilago. Pseudozyma species are usually isolated from plants and rarely from clinical specimens. We report what is believed to be the first paediatric case of central venous catheter (CVC)-related fungaemia associated with P. aphidis. Prompt removal of the CVC in(More)
A cluster of 5 family members, a mother and 4 children, were hospitalized for severe group A Streptococcus (GAS) pneumonia. Three family members had complications: sepsis (1), empyema (2), and a sterile parapneumonic effusion (1). Two additional family members had symptoms of upper respiratory tract infection, and 1 was hospitalized for these symptoms. GAS(More)
Bacterial contamination of platelet products, both single donor apheresis platelet units and whole blood-derived platelet pools, continues to occur despite preventive measures. While some advances have been made in decreasing the rate of bacterial contamination of platelet units, particularly through diversion methods and early culture, a great deal remains(More)
Ectopic hormone production is an uncommon complication of neoplastic lung disease. Rarely, patients may present with signs and symptoms of systemic endocrine dysfunction related to a hormone-secreting tumor. Bronchopulmonary carcinoids are the most common neoplasm implicated in ectopic ACTH-dependent Cushing's syndrome. Persistent hypercortisolism, such as(More)
Thirty-two macrolide-resistant Streptococcus pyogenes isolates were found among 594 clinical isolates collected from 1990 to 1998 in Santiago, Chile, for an overall prevalence of 7.2%. Among the 32 resistant isolates, 28 (87.5%) presented the M phenotype and 4 (12. 5%) presented the MLS(B) phenotype. Serotyping and pulsed-field gel electrophoresis analysis(More)
Antimicrobial susceptibility test methods such as disk diffusion, broth microdilution, and oxacillin screen plate require 24 h of incubation after having the organism growing in pure culture. Rapid and accurate identification of MRSA isolates is essential not only for patient care, but also for effective infection control programs to limit the spread of(More)
We report the first case, to our knowledge, of Blastoschizomyces capitatus infection occurring in a patient receiving empirical echinocandin therapy for neutropenic fevers. Clinicians should consider B. capitatus infection in those neutropenic patients who remain febrile despite echinocandin therapy or who develop yeast bloodstream infections while(More)
There are few data on antibiotic-resistant Streptococcus pneumoniae in Uganda. A total of 191 healthy children in Kampala, Uganda were screened for nasopharyngeal carriage of S. pneumoniae; 118 (62%) of the children were carriers. Antimicrobial susceptibility and serotype of 115 strains was determined. Ninety-six (83.5%) of the isolates were of intermediate(More)
A novel chromogenic medium, Spectra MRSA (Remel, Lenexa, KS), was designed to detect methicillin-resistant Staphylococcus aureus (MRSA) rapidly and more efficiently than traditional media (i.e., tryptic soy agar with 5% sheep blood [SBA] and mannitol salt agar [MSA]). A multicenter study (including four clinical trial sites and the Medical College of(More)
The microbiological similarities of rapidly growing mycobacteria and corynebacteria impose potential for misidentification in the laboratory. This report describes a fatal case of infectious endocarditis caused by Mycobacterium abscessus, initially identified and treated as Corynebacterium spp. Acid-fast staining should be performed routinely when multiple(More)
