“…Other recently described avian Chlamydia species include C. buteonis , isolated from a red-shouldered hawk ( Buteo lineatus ) [ 5 ], and a Candidatus species, Ca. C. ibidis, isolated from sacred ibises ( Threskiornis aethiopicus ) [ 50 ] and crested ibises ( Nipponia nippon ) [ 51 ]. Several chlamydial species primarily associated with human and other mammalian hosts have also been identified in wild birds, including C. trachomatis and C. abortus [ 29 , 52 ], as well as additional Chlamydiaceae which could not be defined to species level [ 29 ].…”

The Chlamydia are a globally distributed genus of bacteria that can infect and cause disease in a range of hosts. Birds are the primary host for multiple chlamydial species. The most well-known of these is Chlamydia psittaci, a zoonotic bacterium that has been identified in a range of wild and domesticated birds. Wild birds are often proposed as a reservoir of Chlamydia psittaci and potentially other chlamydial species. The aim of this review is to present the current knowledge of chlamydial infections in wild avian populations. We focus on C. psittaci but also consider other Chlamydiaceae and Chlamydia-related bacteria that have been identified in wild birds. We summarise the diversity, host range, and clinical signs of infection in wild birds and consider the potential implications of these infections for zoonotic transmission and avian conservation. Chlamydial bacteria have been found in more than 70 species of wild birds, with the greatest chlamydial diversity identified in Europe. The Corvidae and Accipitridae families are emerging as significant chlamydial hosts, in addition to established wild hosts such as the Columbidae. Clarifying the effects of these bacteria on avian host fitness and the zoonotic potential of emerging Chlamydiales will help us to understand the implications of these infections for avian and human health.

The causative agent of ornithosis Chl. psittaci is one of the most dangerous pathogens due to the stability of its natural reservoirs and the large number of susceptible species of animals and human. Humans are almost 100 % susceptible to ornithosis. 90% of the avifauna of Ukraine or 150 species of birds, permanent residents and migratory birds have a high epidemic potential as vectors of Chl. psittaci.The potential danger of chlamydia infection for humans and animals is a significant level of chlamydia infection of synanthropic pigeons, in particular in Kyiv there are birds with asymptomatic disease.In pet stores, bird markets offer ornamental and exotic birds in the city, it made up to 35 -65 % of birds, welfare for infectious diseases was not established.Conducting the initial reception of patients in the clinic, attention was paid to the appearance and behavior of the birds. Changes in behavior patterns, lethargy, apathy or increased excitability could be signs of stress or early signs of illness. Psittacosis can have too many clinical signs at the same time. Therefore, clinical tests do not give the right to a final diagnosis. However, they may be sufficient to suspect possible psittacosis in birds.Among all birds for which the diagnosis of psittacosis was confirmed by laboratory methods (ELISA), there were 55.6 % of medium-sized parrots and budgerigars, 33.3 % of pigeons and several cases of birds of other exotic species.At the initial admission of patients to the clinic, 28.7 % of the birds had signs characteristic of psittacosis. But only in 9.8% of birds the diagnosis was confirmed by laboratory tests. Thus, chlamydia was diagnosed in 3.2 % of all birds -patients of the clinic during the year.Depending on the species of birds and their age, they had different symptoms of psittacosis. However, most of the signs indicated damage to the respiratory organs, or organs of the digestive system, or conjunctivitis.For the treatment of birds diagnosed with psittacosis, complex protocols were used, which included antimicrobial drugs, symptomatic and topical agents. A complex of antibiotics from the macrolide and tetracyclines groups is recognized as the most effective for the treatment of exotic birds from psittacosis. Most of the therapeutic preparations were given to the birds by drinking with water, which is the most convenient for the cage keeping of small birds.The therapeutic efficiency of the developed protocol for treating exotic birds against psittacosis was 77.8 %, which can be characterized as a high rate for this disease.

“…As bactérias do gênero Chlamydia são conhecidas como agentes infectantes e causadores de doenças em várias classes animais, como anfíbios, répteis, aves e mamíferos (Kaleta & Taday, 2003). A clamidiose é uma doença cosmopolita, de caráter infeccioso causada pelas bactérias Gram-negativas do gênero Chlamydia, nas aves, a principal espécie é Chlamydia psittaci, esse agente possui característica de grande infectividade e parasitismo intracelular obrigatório (Guo et al, 2016;Harkinezhad et al, 2009;Kaleta & Taday, 2003;Laroucau et al, 2009;Leal et al, 2015;Li et al, 2020;Poppert et al, 2002;Reavill & Dorrestein, 2018;Sachse et al, 2014Sachse et al, , 2015Tully, 2006;West, 2011).

“…Casos de aves positivas para C. abortus, C. pecorum, C. suis, C. trachomatis e C. muridarum têm sido relatados, apesar da importância epidemiológica desse fato não ser bem esclarecida (Guo et al, 2016;Sachse et al, 2012). Todas as espécies de clamídias possuem potencial zoonótico (Li et al, 2020) uma vez que é evidente a capacidade de vencer a barreira hospedeiro e, portanto, infectar novos hospedeiros, inclusive seres humanos, o que torna a epidemiologia da doença bastante complexa (Guo et al, 2016).…”

“…Os sorotipos de C. psittaci são divididos em A, B, C, D, E, F, EB, 1V, 6N, Matl16, R54, YP84, CPX308, I, J, M56 e WC (Li et al, 2020;Madan et al, 2011;Sachse et al, 2009). Os sorotipos apresentam distribuição entre as ordens e espécies de aves, como o sorotipo A que é endêmico de psitacídeos, sorotipo B comumente isolado de pombos, sorotipo C isolado em patos e gansos, o sorotipo D altamente virulento e correlato as infecções em perus, o sorotipo F isolado em psitacídeos e perus, o sorotipo E que apresenta uma menor especificidade, sendo isolados de pombos, ratitas, patos e perus, assim como o sorotipo EB, isolado principalmente de patos, perus e pombos (Harkinezhad et al, 2009;Proença et al, 2011;Sachse et al, 2009).…”

A clamidiose é umas das afecções de caráter zoonótico mais importante das aves. A doença tem caráter cosmopolita e é listada em diversas espécies animais, inclusive no ser humano. No Brasil, os dados epidemiológicos sobre clamidiose são escassos, principalmente devido à dificuldade de diagnóstico ou acesso a esse. O objetivo dessa revisão é abordar os aspectos fundamentais da clamidiose aviária como patogenia, apresentações clínicas e formas de diagnóstico, além de enfatizar a importância dessa doença na saúde única.
