Whole-genome sequencing analysis of serotype Enteritidis isolated from poultry sources in Mongolia.

serotype Enteritidis ( Enteritidis) is a leading foodborne pathogen associated with poultry products, and the emergence of antimicrobial resistance (AMR) in this serotype poses a growing public health concern, particularly in regions with increasing poultry trade. Between April and June 2024, we collected 114 poultry meat samples (Mongolian domestic and Chinese imported) from retail markets in Mongolia and isolated 45 Enteritidis strains. Antimicrobial susceptibility testing revealed high resistance rates to nalidixic acid (100%), ampicillin (93.

Characteristics of a Temperature-Sensitive Mutant Strain of Enteritidis and Its Potential as a Live Vaccine Candidate.

Enteritidis is a common foodborne pathogen transmitted through poultry products, which are its main carriers. Poultry are vaccinated against Enteritidis in many countries, despite the absence of clinical symptoms, using commercially available live-attenuated vaccines. We previously constructed a highly attenuated temperature-sensitive (ts) Enteritidis mutant, 2S-G10.

Evaluation of Immune Responses and Protective Efficacy of a Novel Live Attenuated Enteritidis Vaccine Candidate in Chickens.

An ideal vaccine for controlling infection in chicken flocks should be safe, inducing both humoral and cellular immunity. Live attenuated vaccines against Enteritidis (. Enteritidis) have been used as a potential control method of infection in the poultry industry.

Genome Analysis of Nicotinamide Adenine Dinucleotide-Independent Isolates From Korea.

(MS) is an avian pathogen that causes respiratory disease, infectious synovitis, and eggshell apex abnormalities in chickens. Nicotinamide adenine dinucleotide (NAD)-independent MS was first reported in 1975. Despite the atypical traits of NAD-independent MS, its independence from NAD has not been studied.
