ABSTRACT
A existência de populações numerosas de pombos (Columba livia) em centros urbanos, em quase todo o mundo, tem se tornado um risco à saúde pública em vista das zoonoses que podem transmitir. A infecção por Chlamydophila psittaci foi avaliada em pombos que frequentam áreas públicas, como praças, ruas e pontos turísticos na cidade de Salvador, Bahia, por meio da PCR em amostras de fezes frescas, suabes cloacais e orofaríngeos. O estudo revelou uma frequência de infecção por C. psittaci de 11,7% (16/137) dos pombos, e oito dos 10 locais pesquisados apresentavam aves infectadas. A detecção de C. psittaci em amostras de cloaca e orofaringe foi maior (15,8% - 3/19) que em amostras de fezes frescas (11% - 13/118). Os resultados demonstram a ocorrência de infecção por C. psittaci em pombos que habitam as áreas públicas da cidade de Salvador e apontam para a necessária elaboração de medidas de controle e monitoramento das populações de pombos urbanos, bem como de ações voltadas à conscientização da sociedade sobre os riscos à saúde pública.
The existence of numerous pigeon (Columba livia) populations in urban centers, in most of the world, has become a public-health risk given the zoonoses they can transmit. Infection with Chlamydophila psittaci was evaluated in pigeons that frequent public areas, such as squares, streets and tourist sites in the city of Salvador, through PCR from fresh feces samples, cloacal swabs and oropharyngeals. The study revealed a frequency of infection with C. psittaci of 11.7% (16/137) in pigeons, and infected birds were found in eight of the ten locales researched. The detection of C. psittaci in samples of cloaca and oropharyngs was greater (15.8% - 3/19) than in the samples of fresh feces (11% - 13/118). The results show the occurrence of infection with C. psittaciem in pigeons that live in public areas in the city of Salvador and points to the necessity of elaborating control and monitoring measures for the populations of urban pigeons as well as developing actions that will raise society´s awareness of these risks to public health.

Experimental model for chlamydial abortion was planned using pregnant guinea pigs to study whether the isolate of Chlamydia psittaci from natural cases of sheep abortion is able to cause experimental abortion in pregnant guinea pigs or not. Follow up and clinical observations like thermal reaction and haematological changes exhibited biphaic febrile response and marked leucopenia in both intraperitoneal group as well as intravaginal group. The laboratory examinations revealed presence of chlamydial intracytoplasmic inclusions in the impression smears of aborted foetal tissues. C. psittaci was reisolated successfully from all the aborted foetal tissues. It was observed that rate and severity of abortion were more in the intraperitoneal group as compared to intravaginal group. On correlating the results of clinical and laboratory examinations it was observed that guinea pig can be used as a suitable model for chlamydial abortion in future studies like cell mediate immune response and to see protective role of chlamydial vaccine, if any.

Las clamidias son procariotas, parásitos intracelulares oblogatorios. El género tiene dos especies: la Chlamydia trachomatis y la Clamydia psitacci; la primera parasita sólo al hombre mientras que la segunda tiene un amplio espectro de hospederos en aves, mamíferos y accidentalemte en el hombre. La C. trachomatis produce enfermedades extraoculares como el linfogranuloma venéreo, probablemente el síndrome de Reiter, uretritis en el hombre, cervicitis y salpingitis en la mujer, rinofaringitis, neumonías infantoles y ocasionalmente otitis media. Las enfermedades oculares que produce son: la conjuntivitis neonatorum, la conjuntivitis de los individuos sexualmente activos, la conjuntivitis de las piscinas y el tracoma
