“…C. psittaci is responsible worldwide for respiratory tract infections ranging from benign illness to severe pneumoniae with fatal outcomes. The primary reservoir of C. psittaci is birds, in particular parrots and parakeets (Longbottom & Coulter, 2003), but recent studies on chicken from the food industries and on feral pigeons suggest a significant prevalence of C. psittaci in these animals as well (Magnino et al, 2009;Geigenfeind et al, 2012;Yin et al, 2013). Transmission between birds is primarily achieved through the inhalation of aerosols containing desiccated infectious particles originating from contaminated birds faeces.…”

Chlamydia psittaci and Chlamydia abortus are closely related intracellular bacteria exhibiting different tissue tropism that may cause severe but distinct infection in humans. C. psittaci causes psittacosis, a respiratory zoonotic infection transmitted by birds. C. abortus is an abortigenic agent in small ruminants, which can also colonize the human placenta and lead to foetal death and miscarriage. Infections caused by C. psittaci and C. abortus are underestimated mainly due to diagnosis difficulties resulting from their strict intracellular growth. We developed a duplex real-time PCR to detect and distinguish these two bacteria in clinical samples. The first PCR (PCR1) targeted a sequence of the 16S-23S rRNA operon allowing the detection of both C. psittaci and C. abortus. The second PCR (PCR2) targeted the coding DNA sequence CPSIT_0607 unique to C. psittaci. The two PCRs showed 100 % detection for ¢10 DNA copies per reaction (1000 copies ml 21 ). Using a set of 120 samples, including bacterial reference strains, clinical specimens and infected cell culture material, we monitored 100 % sensitivity and 100 % specificity for the detection of C. psittaci and C. abortus for PCR1. When PCR1 was positive, PCR2 could discriminate C. psittaci from C. abortus with a positive predictive value of 100 % and a negative predictive value of 88 %. In conclusion, this new duplex PCR represents a low-cost and time-saving method with high-throughput potential, expected to improve the routine diagnosis of psittacosis and pregnancy complication in largescale screening programs and also during outbreaks.

“…Portanto, a população de pombos no ambiente urbano é uma questão complexa, a qual demanda um planejamento cuidadoso das autoridades locais, de forma a evitar a superpopulação dessas aves e, consequentemente, gastos dispendiosos com a saúde pública e o patrimônio. Mas antes de qualquer intervenção, é obrigatório realizar uma avaliação da situação local quanto ao número de aves e seus locais de agregação (Magnino et al, 2009), por isso é fundamental avaliar a eficácia das ações de controle (Feare, 1991).…”

Os pombos domésticos e silvestres estão distribuídos por todo o mundo e carreiam micro-organismos patogênicos ao homem e a outros animais, podendo ser um dos responsáveis pela disseminação de Salmonella spp. Este patógeno gera grande preocupação para a economia mundial, uma vez que cria transtornos para a indústria avícola quando ocorre contaminação dos plantéis e ônus para a saúde pública devido a surtos de infecção alimentar causados por esta bactéria. Dessa forma, objetivou-se realizar um levantamento acerca da participação do pombo doméstico na possível disseminação de Salmonella spp.

“…The infections which have been found to be transmitted from pigeons to humans include campylobacters [33], Chlamydia psittaci, [34,35], Cryptococcus neoformans/Candida albicans [36][37][38][39], Escherichia coli [40,41], Histoplasma capsulatum (from fungus growing on dried feces) [42], Salmonella enterica/S. typhimurium [33,[42][43][44] and viral infections (transmitted by mosquitoes feeding on infected birds) [45,46].…”
