Infection of L cells with Chlamydia psittaci inhibited the burst of deoxyribonucleic acid synthesis that occurs when the host cells are released from a double thymidine block.

Chlamydia psittaci is the etiological agent of psittacosis and is a zoonotic pathogen infecting birds and a variety of mammalian hosts. Here we report the genome sequence of the porcine strain 01DC12 which is representative of a novel clade of C. psittaci belonging to ompA genotype E.

To evaluate a microimmunofluorescence (MIF) test (Chlamydia pneumoniae IgG, Vircell, Spain) that detects IgG against Chlamydophila pneumoniae (Cp), MRL Diagnostics MIF was used as reference test. Cross-reactivity against Chlamydia trachomatis (Ct) and Chlamydophila psittaci (Cps) was investigated. Eighty sera were analysed from 22 subjects with vascular disease, 38 with multiple sclerosis and 2...

Throughout the world, populations of scavenger birds are declining rapidly with some populations already on the brink of extinction. Much of the current research into the factors contributing to these declines has focused on exposure to drug residues, lead, and other toxins. Despite increased monitoring of these declining populations, little is known about infectious diseases affecting scavenge...

BACKGROUND DNA vaccination has been shown to elicit specific cellular and humoral immune responses to many different agents in a broad variety of species. However, looking at a commercial use, the duration of the immune response against the vaccine is critical. Therefore the persistence of the DNA vaccine, as well as its expression, should be investigated. We conducted these investigations on a...

A Chlamydophila psittaci species-specific real-time PCR targeting the rDNA ribosomal spacer was developed as well as a genotype-specific real-time PCR targeting the Cp. psittaci outer membrane protein A (ompA) gene. The SYBR Green-based species-specific real-time PCR detected Cp. psittaci genotypes A to F, and the recently discovered E/B genotype. The genotype-specific real-time PCR could easil...
