Whole-Genome Sequences of Low-Virulence Strain CB3 and Mild Strain CB7 of Chlamydia psittaci.

Avian Chlamydia psittaci is an obligate intracellular zoonotic pathogen especially dispersed from birds, and it is known to cause pericarditis, pneumonia, lateral nasal adenitis, peritonitis, hepatitis, splenitis, and other diseases. Generalized infections result in fever, anorexia, lethargy, and diarrhea, depending on the chlamydial genotype and the affected bird species. Although many complete genomes of C. psittaci have been sequenced, we report here the genomes of two strains isolated from the free-living sparrows (strain CB3) and vinous-throated parrotbill (strain CB7) in China, which were first isolated from the spleens of healthy birds in a routine investigation.
