As a result, additional variability may be introduced to the per se variable antibiotic concentrations in critically ill patients.
The IncJ group of enterobacterial mobile genetic elements, which include R391, R392, R705, R997 and pMERPH, have been shown to be site-specific integrating elements encoding variable antibiotic and heavy metal resistance genes.
Standard antibiotic dosing apparently results in highly variable antibiotic concentrations in the blood and tissues.
The disadvantages are that each mutation connected to variable antibiotic resistance needs to be determined, and that the cost may be high.
Treatment of BV in pregnancy has mixed effects on the risk of preterm delivery, which some hypothesize is due to variable antibiotic efficacy for the fastidious bacteria.
Finally, in the comparison of four strategies for the variable antibiotic use, the study will have a 100% for antibiotic use as an outcome, since the percentage of antibiotic use in the antibiotic therapy arm is likely to exceed 90%.
Finally, a sum variable "antibiotic knowledge" was built, with one point assigned for each correct answer and total values for all three questions ranging from zero to three points.
However, compared to synthetic processes, manufacture by fermentation is more difficult to control; thus, it can lead to the formation of more variable antibiotic products with more complicated and less predictable composition and impurity profiles.
After adjustment for confounding variables, antibiotic exposure in fetal life remained significantly associated with asthma but reduced for any and airway antibiotics.
A Step II model was built by adding treatment-related variables (antibiotic use, length, total dose) one at a time to the final Step I model using conditional logistic regression.
