USA300 strains were differentiated by a stable chromosomalmutation in gyrA conferring quinolone resistance.
2
Bacterial chromosomalmutations that confer antibiotic resistance often have deleterious effects that impose costs on reproductive fitness.
3
The presence of genotoxic agents in the environment may cause chromosomalmutations through different mechanisms, which are associated with serious health effects.
4
This study therefore sought to identify chromosomalmutations and plasmid-mediated resistance as possible mechanisms of fluoroquinolone resistance from clinical isolates in Ghana.
5
Characterized mechanisms of colR in K. pneumoniae are largely due to chromosomalmutations in two-component regulators, although a plasmid-mediated colR mechanism has recently been uncovered.
1
The presence of a specific chromosomalabnormality may augment diagnosis and therapeutic stratification.
2
This chromosomalabnormality is difficult to identify from G-banding alone.
3
This could explain the low prevalence of this chromosomalabnormality observed in the present study.
4
This rare chromosomalabnormality was associated with severe feeding problems in the first years of life.
5
All fetuses should have ultrasonography to exclude other anomalies, and karyotype analysis to exclude chromosomalabnormality.
1
A new cytogenetic hypothesis on the genesis of this rare chromosomeaberration is also discussed.
2
Clastogenic and cytotoxic activities of all agents were tested by examining chromosomeaberration yields in first-division metaphases and by clonogenic survival assays.
3
The findings of clonal chromosomeaberrations in five new cases are presented.
4
The MCB pattern also allows the detection and characterization of chromosomeaberrations.
5
Several different structural chromosomeaberrations have been observed in human neoplasias.

2
The MCB pattern also allows the detection and characterization of chromosomeaberrations.
3
Several different structural chromosomeaberrations have been observed in human neoplasias.
4
This finding is consistent with the known association of chromosomeaberrations with cancer-risk.
5
No significant increase in the frequencies of chromosomeaberrations were found.

5
Partial trisomy 9p is a frequently described chromosomeabnormality.
6
The chromosomeabnormality was detected by amniocentesis and was confirmed postnatally in cultured skin fibroblasts.
7
She also had a distinctive chromosomeabnormality in blood cells but not in other tissues.
8
This chromosomeabnormality may therefore be underdiagnosed.
9
Microduplication of chromosome 17p13.1 is a rarely reported chromosomeabnormality associated with neurodevelopmental delays.
10
This chromosomeabnormality was detected in cultured amniocytes from a 20-week pregnancy presenting with intrauterine growth retardation and echogenic bowel.
11
However, an interstitial deletion of the long arm of chromosome 3 was found, as the sole chromosomeabnormality, in three cases.
12
Univariate analysis showed that age, chromosomeabnormality, percentage of bone marrow blast cells and number of cytopenias were significantly related to prognosis.
13
This structural chromosomeabnormality is characteristic of this specific disease and occurs often as the only chromosomeabnormality in the malignant cells.
14
It is concluded that most of CLL patients have chromosomeabnormality, and the number abnormality are more frequent than the structural aberrations.
15
In 37 cases with no karyotypic or cryptic chromosomeabnormality, sequence analysis of the PAX6 gene was performed.
16
Identifying the position of the breakpoints in this rearrangement provides the means to search for candidate genes rearranged by this highly specific structural chromosomeabnormality.
