EFFECT OF IN-FEED ADMINISTRATION OF TYLOSIN PHOSPHATE ON ANTIBIOTIC RESISTANCE IN ENTEROCOCCI ISOLATED FROM FEEDLOT STEERS

Effect of in-feed administration of tylosin phosphate on antibiotic resistance in enterococci isolated from feedlot steers

Tylosin phosphate is a macrolide commonly administered to cattle in North America for the control of liver abscesses.This study investigated the effect of in-feed administration of tylosin phosphate to cattle Ball - Floorball at subtherapeutic levels and its subsequent withdrawal on macrolide resistance using enterococci as an indicator bacterium.F

V2-Directed Vaccine-like Antibodies from HIV-1 Infection Identify an Additional K169-Binding Light Chain Motif with Broad ADCC Activity

Summary: Antibodies that bind residue K169 in the V2 region of the HIV-1 envelope correlated with reduced risk of infection in the RV144 vaccine trial but were restricted to two ED-motif-encoding light chain genes.Here, we identify an HIV-infected donor with high-titer V2 peptide-binding antibodies and isolate two antibody lineages (CAP228-16H/19F

VP0 Myristoylation Is Essential for Senecavirus A Replication

Many picornaviruses require the myristoylation of capsid proteins for viral replication.Myristoylation is a site-specific lipidation to the N-terminal G residue of viral proteins, which is catalyzed by the ubiquitous eukaryotic enzyme N-myristoyltransferase (NMT) by allocating the myristoyl group to the N-terminal G residue.IMP-1088 and DDD85646 ar
