Independent distributions of colonizations occurred in the controls, but independent colonizations did not occur in the semi-shaded blocks; this confirmed the negative phototaxis hypothesis.
However, there are no data correlating colonization sites with lighting conditions.
The first hypothesis tested was that favorable colonization sites in lighted areas are more likely to be selected by alates of C.
Frequently identified risk factors for VRE colonization and infection include prolonged hospital stays, exposure to intensive care units, transplants, hematologic malignancies, and exposure to antibiotics (31).
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).
Stool samples were subsequently collected over a 2- to 3-week period to determine whether high-level VRE colonization was established.
First, the prevalence of NTM pulmonary infection and colonization significantly increased during the period, whereas prevalence of M.
tuberculosis infection, NTM pulmonary infection, and NTM colonization were more common among men than among women (70.
Moreover, the prevalence of NTM pulmonary infection and colonization rapidly increased with time.
For recovery of EF3030 and mutants from mice in the pneumonia and colonization models, mice were killed 7 days postinfection, samples were collected, and CFUs were counted in nasal washes, lungs, and blood as described previously (19,20).
Thus, although Phe/Phe was less efficient at nasopharyngeal colonization when competing with EF3030, it colonized as well as EF3030 when tested alone.
The fitness of pathogenic bacteria to cause disease relies on several factors, including colonization of the host, evasion of host defenses, propagation on or inside the host, and transmission to a new host.
