Yersinia ruckeri is a gram-negative pathogen causing enteric redmouth disease in salmonids. Previous studies have reported that Y. ruckeri harbors an ampC gene that is expressed at low level. In this present work, the entire ampC gene of Y. ruckeri was cloned and expressed in Escherichia coli. The AmpC enzyme confers resistance to aminopenicillins and narrow-spectrum cephalosporins, which fit w...
A polyphasic characterization of atypical isolates of Yersinia ruckeri (causative agent of enteric redmouth disease in trout) obtained from hatchery-reared brown trout Salmo trutta in South Carolina was performed. The Y. ruckeri isolates were biochemically and genetically distinct from reference cultures, including the type strain, but were unequivocally ascribed to the species Y. ruckeri, base...
Yersinia species cause zoonotic infections, including enterocolitis and plague. Here we studied Yersinia ruckeri antifeeding prophage 18 (Afp18), the toxin component of the phage tail-derived protein translocation system Afp, which causes enteric redmouth disease in salmonid fish species. Here we show that microinjection of the glycosyltransferase domain Afp18(G) into zebrafish embryos blocks c...
BACKGROUND Enteric Redmouth (ERM) disease also known as Yersiniosis is a contagious disease affecting salmonids, mainly rainbow trout. The causative agent is the gram-negative bacterium Yersinia ruckeri. The disease can be diagnosed by isolation and identification of the causative agent, or detection of the Pathogen using fluorescent antibody tests, ELISA and PCR assays. These diagnostic method...
