In 1995 and 1996, PHLS confirmed 265 isolates from residents of England and Wales as nontoxigenic C.
Corynebacterium ulcerans0102 carries the gene encoding diphtheria toxin on a prophage different from the C.
After years of stagnation, the number of complete C.
During the study period (1998-2004) the rate of detection of C.
This phenomenon has not been documented in any countries reporting nontoxigenic C.
Clinical manifestations and immunization status for case-patients with toxigenic C.
Cultures of oropharyngeal swab samples obtained from each person were negative, including cystine tellurite blood agar, which is selective for C.
Toxigenicity of the strain, named KL126, was verified by using a C.
Because of the nearly complete disappearance of cutaneous diphtheria in many parts of the western world, microbiologists lack experience in identifying C.
The swabs flora the throat and lesions yielded toxigenic C.
ulcerans was proven to produce diphtheria toxin identical to C.
To allow better monitoring of the global spread of diphtheria, the WHO ribotyping database for C.
