a, Mice were pretreated with an antibiotic cocktail administered in the drinking water for 3 weeks (ABX) before, and during, 7 d of doxycycline administration (doxy), with or without vitamin B12supplementation according to the schematic.b, Representative histology images and quantification of a ...
The term "broad spectrum antibiotics" was originally used to designateantibiotics that were effective against both gram-positive and gram-negative bacteria, in contrast to penicillin, which is effective chiefly against gram-positive organisms, and streptomycin, which is active primarily against gram-negat...
Bacterial numbers were enumerated by plating serial dilutions on TSA plates supplemented with 100 µl of catalase (38,000 U/ml; Worthington Biochemical Corporation, NJ) and the desired antibiotic (250 µg/ml kanamycin, 200 µg/ml streptomycin, or 200 µg/ml spectinomycin) and...

In addition, antibiotic treatment should also lead to reduced SN38 formation and damage of intestinal tissues. Streptomycin/neomycin treatment depleted over 90% of the major bacteria species in the gut. This finding is consistent with other reports in the literature[24, 45]. We observed that ...

Human umbilical vein endothelial cells (HUVECs) were obtained from PromoCell (#C12203, Leicestershire, UK). Cells were cultured (passages 1 to 4) in Endothelial Growth Cell Medium (EGM2 #C22111) supplemented with antibiotics (100 units/mL penicillin and 100 µg/mL streptomycin #P43333, Sig...
and grown to confluence in Dulbecco's modified Eagles medium containing 10% fetal bovine serum (FBS), insulin (10 μg/ml), transferrin (5 μg/ml), glutamine (4 mmol/l), penicillin (100 units/ml), and streptomycin (100 μg/ml), incubated at 37 °C in a humidified atmosphere of 5%...
Of the four standard TB antibiotics used in “short course” treatment (HRZE), only Rifampin, which inhibits bacterial RNA polymerase, is a broad-spectrum antimicrobial that is used for non-mycobacterial infections. The effects of this prolonged antibiotic regimen on the intestinal microbiota are ...
