Helicobacter pullorum in Chickens, Belgium
A total of 110 broilers from 11 flocks were tested for Helicobacter pullorum by polymerase chain reaction; positive samples were reexamined with a conventional isolation method. H. pullorum isolates were examined by amplified fragment length polymorphism (AFLP) fingerprinting for interstrain genetic diversity and relatedness. Sixteen isolates from cecal samples from 2 different flocks were obta...
متن کاملIsolation and identification of Helicobacter pullorum from caecal content of broiler chickens in Mashhad, Iran
The presence of Helicobacter pullorum in intestinal tract of broiler chickens may be a potential risk for human health. In this study, a total of 100 caecal samples of broilers carcasses from 20 flocks at a poultry abattoir in Mashhad suburb were tested for the presence of H. pullorum using modified conventional culture method by combination of culturing on Brucella sheep blood agar and a filte...
متن کاملComparative Genomics of Helicobacter pylori Strains of China Associated with Different Clinical Outcome
In this study, a whole-genome CombiMatrix Custom oligonucleotide tiling microarray with 90,000 probes covering six sequenced Helicobacter pylori (H. pylori) genomes was designed. This microarray was used to compare the genomic profiles of eight unsequenced strains isolated from patients with different gastroduodenal diseases in Heilongjiang province of China. Since significant genomic variation...
متن کاملHelicobacter pullorum: An Emerging Zoonotic Pathogen
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...
متن کاملComparative genomics of the restriction-modification systems in Helicobacter pylori.
Helicobacter pylori is a Gram-negative bacterial pathogen with a small genome of 1.64-1.67 Mb. More than 20 putative DNA restriction-modification (R-M) systems, comprising more than 4% of the total genome, have been identified in the two completely sequenced H. pylori strains, 26695 and J99, based on sequence similarities. In this study, we have investigated the biochemical activities of 14 Typ...
