16S rRNA mutation-mediated tetracycline resistance in Helicobacter pylori.
Most Helicobacter pylori strains are susceptible to tetracycline, an antibiotic commonly used for the eradication of H. pylori. However, an increase in incidence of tetracycline resistance in H. pylori has recently been reported. Here the mechanism of tetracycline resistance of the first Dutch tetracycline-resistant (Tet(r)) H. pylori isolate (strain 181) is investigated. Twelve genes were sele...
متن کاملHelicobacter 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 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 کاملMutations in the 16S rRNA genes of Helicobacter pylori mediate resistance to tetracycline.
Low-cost and rescue treatments for Helicobacter pylori infections involve combinations of several drugs including tetracycline. Resistance to tetracycline has recently emerged in H. pylori. The 16S rRNA gene sequences of two tetracycline-resistant clinical isolates (MIC = 64 microg/ml) were determined and compared to the consensus H. pylori 16S rRNA sequence. One isolate had four nucleotide sub...
متن کاملAn intervening sequence (IVS) in the 16S rRNA gene of the eubacterium Helicobacter canis.
PCR amplicons enlarged by approximately 250bp were generated from the 16S rRNA (rrs) genes of certain strains of the recently described Helicobacter species, H. canis. The DNA sequence of the rrs gene of one such strain was determined, and it was shown that an intervening sequence (IVS) of 235bp followed nucleotide 199 in the rrs sequence. In four other H. canis strains, identical or similar IV...
