Protective Efficacy of a Commercial Live Attenuated aroA mutant Vaccine Against Avian Pathogenic Escherichia coli Challenge in Broilers

Immunogenicity and protective efficacy of a Salmonella Enteritidis sptP mutant as a live attenuated vaccine candidate

BACKGROUND Salmonella enterica serovar Enteritidis (S. Enteritidis) is a highly adaptive pathogen in both humans and animals. As a Salmonella Type III secretion system (T3SS) effector, Salmonella protein tyrosine phosphatase (SptP) is critical for virulence in this genus. To investigate the feasibility of using C50336ΔsptP as a live attenuated oral vaccine in mice, we generated the sptP gene de...

Breast Muscle Characteristics of Avian Pathogenic Escherichia Coli Infected Broilers Fed with Antibiotics or Probiotic

The study was conducted to evaluate the impact of feeding multistrain probiotic on breast muscle characteristics of avian pathogenic Escherichia coli (APEC) infected broilers. Three hundred and thirty six Lohmann MB-202 day-old-chicks were divided to four treatment groups, including CNTRL (chicks receiving basal diet and not infected), APEC (chicks receiving basal diet and infected with APEC), ...
