Salmonella enterica Enteritidis (S. Enteritidis) and Salmonella enterica Pullorum (S. pullorum) are regarded as a threat to poultry production. This study's aim is to characterize the expression profiles in response to three different challenges and to identify infection-related genes in the chicken spleen and caecum. Groups of the Chinese chicken breed Langshan were challenged with either S. E...

background salmonella spp. is the major bacterial pathogen in poultry and is responsible for significant economic losses of the poultry industry in many parts of the world. among salmonella spp., salmonella gallinarum and s. pullorum are the most common causative agents of chicken salmonellosis resulting in high mortality and morbidity. objectives the aim of this study was to identify s. gallin...

Bile-tolerant Helicobacter species such as Helicobacter pullorum, Helicobacter bilis, and Helicobacter hepaticus are associated with hepatic disorders in animals and may be involved in the pathogenesis of chronic liver diseases (CLD) in humans. Antibody responses to cell surface proteins of H. pullorum, H. bilis, and H. hepaticus in serum samples from patients with CLD, a randomized population ...

Salmonella enterica serovars Enteritidis, Pullorum/Gallinarum, and Dublin are infectious pathogens causing serious problems for pig, chicken, and cattle production, respectively. Traditional serotyping for Salmonella is costly and labor-intensive. Here, we established a rapid multiplex PCR method to simultaneously identify three prevalent Salmonella serovars Enteritidis, Pullorum/Gallinarum, an...

The 1,007,172-bp complete genome of Mycoplasma pullorum strain B359_6, isolated from domestic chickens, has been sequenced, assembled, and annotated.

In the course of various investigations of microorganisms in spray-dried whole-egg powder, it became apparent that further information concerning the nutrition and metabolism of the genus Salmonella was essential. A survey of the literature revealed that little attention has been given this genus in this respect. Such information would be of value in improving the present methods of isolation a...

Helicobacter pullorum (H.pullorum) commonly colonizes the gastrointestinal tract of poultry causing gastroenteritis. The bacterium may be transmitted to humans through contaminated meat where it has been associated with colitis and hepatitis. Despite the high prevalence of H. pullorum observed in poultry, little is known about the mechanisms by which this bacterium establishes infection in host...

Salmonella is the chief causative agent to cause mortality and reduced production in poultry industry. Fowl typhoid and pullorum disease are the two main bacterial diseases which is caused by Salmonella gallinarum and Salmonella pullorum respectively and having zoonotic importance. Enteritis, bacteremia, reduced egg production, diarrhea, inappetance are the main signs and symptoms caused by the...

Mycoplasmas were isolated from chickens with respiratory problems during field investigations of a concentrated respiratory disease outbreak in western Cuba, 1997. A high percentage of mycoplasma cultures from tracheas and air-sac lesions yielded pure cultures of Mycoplasma pullorum. The aim of the present work was to investigate the heterogeneity among M. pullorum isolates from Cuba and strain...

The first bacterial N-linked glycosylation system was discovered in Campylobacter jejuni, and the key enzyme involved in the coupling of glycan to asparagine residues within the acceptor sequon of the glycoprotein is the oligosaccharyltransferase PglB. Emerging genome sequence data have revealed that pglB orthologues are present in a subset of species from the Deltaproteobacteria and Epsilonpro...
