Three isolates identified as NAP1
by PFGE differed from the epidemic strain by having toxinotype IX/XIII and lacking the 18-bp deletion.
An excess proportion of deaths caused by CD027 and other strains with binary toxin corroborates recent evidence from Canada, which showed an increased risk for death in patients infected with the NAP1
difficile, including the A-B+ 1470 variant, as well as the NAP1
The rising prevalence of CDI may be attributable to the emergence of the hypervirulent NAP1
strain, which could potentially cause a higher clinical failure rate," said Youe-Kong Shue, Ph.
This increase is assumed to be associated with higher toxin production by a fluoroquinolone-resistant strain belonging to pulsed-field gel electrophoresis type NAP1
, PCR ribotype 027, and toxinotype III (2,3).
Genotypes resembling human PCR ribotype 027/ NAP1
were found in 30.
PFGE divided 027/ TT III isolates into NAP1
(>80% related to human NAP1
) and NAP1
-related (78% related to human NAP1
) groups and 078/TT V isolates into NAP7 and NAP8 groups (Figure).
The Centers for Disease Control and Prevention has reported outbreaks of CDAD associated with the new BI/ NAP1
strain in 40 of 50 US states, although the association between BI/NAP1
and severe disease was not consistent among all facilities (11).
Historically, endemic CDAD has been reported to be associated with minimal increased risk in mortality although NAP1
strain CDAD outbreaks have been associated with much higher attributable mortality (10,11,13).
