Antibiotics other than glycopeptides have been linked with increased risk for colonization
and infection with VRE, most prominently, the extended-spectrum cephalosporins and antibiotics with potent activity against anaerobic bacteria (26,31,38,39).
Table 5 shows the comparison between the presence of malignancy and bacterial colonization
over epidural catheter tip in our study.
The median clinical disease severity score for those with potentially pathogenic bacterial colonization
was 5, compared with a median score of 4 in those without colonization
(P = .187).
In contrast to the decreasing trend in prevalence of TB during the study period, the annual incidence of pulmonary NTM disease and colonization
increased significantly over time (p<0.01) (Figure 1).
Again, though many works have been done on mycorrhizal colonization
in other tropical countries such as India, Malaysia, Indonesia very little research work has been reported from Bangladesh .
There were no significant differences in number of colonizations
between the 10-cm sections (P [greater than or equal to] 0.29) in the control boards.
We illustrate our theoretical conclusion with data from some species of salamanders that appear to have undergone major range expansions with, we hypothesize, some kin-structured colonization
. We conclude that, whenever total nuclear genetic variation exceeds that in the cytoplasmic genome, colonization
events may be as likely an explanation as a "selective sweep" of the cytoplasrnic genome (Nei et al.
The authors calculated odds ratios (ORs) by considering a bacterial colonization
as an outcome variable and another bacterial colonization
as an exposure variable.
The next most effective strategy, according to the analysis, would be a combination of universal contact precautions and universal CHG baths, which would prevent about 38% of colonizations
and 40% of infections, said Dr.
In Response: We thank Hernandez-Garduno and Elwood for drawing attention to the issue of nontuberculous mycobacteria (NTM) colonization
(1), which was not described in our study (2).
These 3 strains were analyzed by using an in vitro growth model, an in vivo nasopharyngeal colonization
model, and an in vivo pneumonia model.
The exclusion criteria consisted of colonization
with BCC bacteria and/or the absence of chronic colonization
