OBJECTIVE The effect of flavonoids from alfalfa on the microbial flora was determined using molecular techniques of 16S ribosome deoxyribonucleic acid (rDNA) analysis. METHODS Four primiparous Holstein heifers fitted with ruminal cannulas were used in a 4×4 Latin square design and fed a total mixed ration to which alfalfa flavonoids extract (AFE) was added at the rates of 0 (A, control), 20 (...
In vitro models using human primary epithelial cells are essential in understanding key functions of the respiratory epithelium in the context of microbial infections or inhaled agents. Direct comparisons of cells obtained from diseased populations allow us to characterize different phenotypes and dissect the underlying mechanisms mediating changes in epithelial cell function. Culturing epithel...
Newborn babies admitted into the neonatal intensive care unit (NICU) often require many supportive invasive devices and frequently receive antimicrobial therapy. We investigated the microbial flora in NICU patients reporting the distribution of infections in different catheter sites. Results showed that 97% of samples were positive; in particular 11% were positive for two or more microbial agen...
