Many strains of Chlamydia suis, a pathogen of pigs, express a stable tetracycline resistance phenotype. We demonstrate that this resistance pattern is associated with a resistance gene, tet(C), in the chlamydial chromosome. Four related genomic islands were identified in seven tetracycline-resistant C. suis strains. All resistant isolates carry the(More)
The effects of histamine and its antagonists on the release of prostaglandin E and F2alpha (PGE and PGF2alpha) and the 15-keto-13,14-dihydro PGF2alpha/E (metabolites) were examined in minced and whole perfused guinea pig lung. Lung fragments released considerable amounts of prostaglandins into the incubation media with time alone: parenchyma more PGF2alpha(More)
Stable tetracycline resistance in Chlamydia suis is mediated by a family of genomic islands [the tet(C) islands] that are integrated into the chlamydial chromosome. The tet(C) islands contain several plasmid-specific genes, the tet(C) resistance gene and, in most cases, a novel insertion element (IScs605) encoding two predicted transposases. The hypothesis(More)
