The effects of a live yeast supplement [Saccharomyces cerevisiae subspecies boulardii CNCM I-1079; ProTernative Stress Formula (PTSF) yeast, Ivy Natural Solutions, Overland Park, KS] on DMI, performance, and health of beef cattle were evaluated in 3 experiments. In Exp. 1, a pilot study was conducted with 10 healthy beef steers fed a 65% concentrate diet to evaluate the effects of florfenicol (...

The effect of ionizing radiation on florfenicol (FF), an antibiotic with wide antibacterial properties was investigated to determine whether it can be sterilized using high-energy radiation. FF was irradiated by E-beam radiation to doses of 25-800 kGy, and then changes in the physico-chemical properties were examined using chromatographic methods (TLC and HPLC), spectroscopic methods (NMR and M...

1. Florfenicol, proposed for treatment of bovine respiratory disease also called shipping fever or transit fever, is a wide spectrum, synthetic antibacterial substance. It is structurally related to D (-)threo chloramphenicol (CAP), but differs from it in two fundamental aspects : firstly, presence of a pmethyl sulfonyl group instead of the p-nitro group, secondly, presence of fluorine atom ins...

Bacteria from the family Flavobacteriaceae often show low susceptibility to antibiotics. With the exception of two Chryseobacterium spp. isolates that were positive for the florfenicol resistance gene floR, no clinical resistance genes were identified by microarray in 36 Flavobacteriaceae isolates from salmonid fish that could grow in ≥ 4 mg/L florfenicol. Whole genome sequence analysis of the ...
