BACKGROUND Pathogens with the zoonotic potential to infect humans, such as Campylobacter jejuni, Campylobacter coli and Chlamydophila psittaci, can be found in feral pigeons (Columba livia). Given the high density of these birds in the public parks and gardens of most cities, they may pose a direct threat to public health. METHODS A total of 118 pigeons were captured in three samplings carrie...

Psittacosis is a zoonotic disease caused by Chlamydophila psittaci. The most common presentation is atypical pneumonia. Three cases of pneumonia of varying severity due to psittacosis are described. All patients had a history of avian contact. The diagnosis was confirmed by molecular detection of Chlamydophila psittaci in respiratory specimens. The cases showed good recovery with doxycycline tr...

During a study on Trypanosoma equiperdum propagation in adult male Wistar rats, four rats died spontaneously. Two of the dead animals were subjected to post mortem examination. From different organs of the rats, chlamydiae were isolated and confirmed by PCR and DNA sequencing as Chlamydophila psittaci. The results show that infection with Chlamydophila psittaci may occur in laboratory rats. Suc...

With interest we read the article of Saito et al. that describes a severe case of chlamydiosis in humans (3). However, according to us two major points need to be clarified. The taxonomy of chlamydiae has been illustrated in 1999 by Everett et al. (1), and such classification is accepted universally, as evidenced by a number of manuscripts published in recent years. Classification is based on d...

Pathological and serological evidence and DNA-DNA reassociation data indicate that Chlamydophila psittaci and Chlamydophila abortus are separate species. C. psittaci causes avian systemic disease and C. abortus causes abortion. Both previously belonged to Chlamydia psittaci are associated with zoonotic and enzootic outbreaks. Genetic studies suggest that they are closely related and because of ...

Chlamydophila psittaci was detected in 10% of 431 fulmars examined from the Faroe Islands. Analysis of ompA showed a sequence almost identical to that of the type strain. The origin of C. psittaci outbreaks in fulmars is discussed. Despite a high level of exposure, the risk for transmission of C. psittaci to humans is low.

Introducción: Chlamydophila psittaci es una bacteria zoonótica e intracelular estricta, que provoca la psitacosis humana y su principal hospedero son las aves psitácidas. La cotorra argentina un ave psitácida nativa de Sudamérica actualmente considerada especie invasora en 19 países, incluyendo Chile.
