Multicenter Evaluation of a
Candida albicans
Peptide Nucleic Acid Fluorescent In Situ Hybridization Probe for Characterization of Yeast Isolates from Blood Cultures
ABSTRACT We evaluated aliquots from 244 clinical blood culture bottles that demonstrated yeasts on Gram stain using a Candida albicans peptide nucleic acid (PNA) fluorescent in situ hybridization (FISH) probe. The sensitivity, specificity, positive predictive value, and negative predictive value of the C. albicans PNA FISH test in this study were 99%, 100%, 100%, and 99.3%, respectively.
Mycobacterium triplex
Infection in a Liver Transplant Patient
ABSTRACT Mycobacterium triplex was first named in 1996 as an acid-fast bacillus with features that most resemble Mycobacterium simiae and Mycobacterium avium-intracellulare complex but which possesses a distinct mycolic acid pattern as well as a distinctive 16S rRNA hypervariable region. It has been isolated from lymph node, sputum, and cerebrospinal fluid specimens, but to date only rare clinical cases of this organism have been reported in the literature. The following is a case report of M. triplex that was isolated from the pericardial and peritoneal fluid of a 13-year-old female liver transplant patient.
