“…Despite this, little attention has been given to this avian species in Brazil, where its numbers have been increasing. Moreover, few data about health issues relating to wild pigeons are available in the veterinary medical literature (PEREZ, 2005;FERREIRA et al, 2016).…”

The present study analyzed gastrointestinal helminth communities in 265 wild pigeons (Columba livia) living in the municipalities of São Paulo and Tatuí, state of São Paulo, Brazil, over a one-year period. The birds were caught next to grain storage warehouses and were necropsied. A total of 790 parasites comprising one nematode species and one cestode genus were recovered from 110 pigeons, thus yielding an overall prevalence of 41.5%, mean intensity of infection of 7.2 ± 1.6 (range 1-144) and discrepancy index of 0.855. Only 15 pigeons (5.7%) presented mixed infection. The helminths isolated from the birds were Ascaridia columbae (Ascaridiidae) and Raillietina sp. (Davaineidae). The birds' weights differed according to sex but this did not influence the intensity of infection. The overall prevalence and intensity of infection did not differ between the sexes, but the prevalence was higher among the birds from Tatuí (47.8%). The gastrointestinal helminth community of C. livia was characterized in the two areas studied and parasite homogeneity was observed over the 12 months analyzed at both locations. These results make contributions to the current literature on health aspects of wild C. livia populations.Keywords: Columbiformes, helminthology, nematodes, cestodes, Ascaridia, Raillietina. ResumoO presente estudo analisou comunidades gastrointestinais de helmintos em 265 indivíduos de Columba livia de vida livre nos municípios de São Paulo e Tatuí, estado de São Paulo, Brasil, durante um ano. As aves foram capturadas em áreas de armazenamento de grãos e sementes e necropsiadas. Um total de 790 parasitos representando uma espécie de nematódeo e um gênero de cestoide foram recuperados de 110 pombos com uma prevalência geral de 41,5%, intensidade média de infecção de 7,2 ± 1,6 (amplitude 1-144) e índice de discrepância de 0,855. Somente 15 (5,7%) pombos tiveram uma infecção mista. Os helmintos isolados das aves foram Ascaridia columbae (Ascaridiidae) e Raillietina sp. (Davaineidae). O peso das aves foi diferente entre os sexos, mas não influenciou a intensidade de infecção. A prevalência geral e a intensidade de infecção não foram diferentes entre sexo, mas a prevalência foi maior nas aves de Tatuí (47,8%). A comunidade gastrointestinal de helmintos de C. livia foi caracterizada nas duas áreas estudadas e uma homogeneidade de parasitos foi observada nos 12 meses analisados, em ambas localidades. Os resultados contribuem para a literatura atual sobre aspectos sanitários de populações de C. livia em vida livre.

“…C. psittaci has since been identified in European feral pigeon populations in further studies [ 47 , 48 ]. Surveillance of feral pigeon populations for C. psittaci has also been carried out outside Europe, in countries including Brazil [ 68 , 69 ], Japan [ 67 ], and Thailand [ 70 , 71 ]. In Australia, C. psittaci has been isolated from an individual spotted dove ( Streptopelia chinensis ), and a strain primarily associated with Columbiformes was also isolated from infected equine samples [ 72 ].…”

A Review of Chlamydial Infections in Wild Birds

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.

“…Newcastle disease (ND) caused by avian paramyxovirus serotype 1 (APMV-1) viruses can be diagnosed in specimens from both live and dead birds. Most commonly in live birds, swabs of the pharyngeal area and/or cloacae (or faeces) may be tested at appropriate diagnostic laboratories using virus isolation [5,10]. During seasonal outbreaks of ND, laughing doves and pigeons are usually knocked down and may be found dead under trees or in gutters [17].…”

“…These wild doves may act as sentinel animals for the monitoring of ND in an area known for the production of poultry by backyard and large scale poultry farms [10]. The trapping of these doves routinely and sampling for Newcastle disease virus (NDV) may assist avian disease monitoring and surveillance teams predict the eventual outbreak of ND in poultry farms in a region [5,10].…”

Detection of Newcastle Disease Virus (NDV) in Laughing Doves and the Risk of Spread to Backyard Poultry

et al. 2020

Newcastle disease (ND) is a highly infectious viral disease of birds caused by the Newcastle disease virus (NDV) and doves have been incriminated in previous outbreaks of the disease that have discouraged backyard poultry productions. This survey was done to detect and characterize the NDV from 184 swabs from the cloacae and pharynxes of 67 trapped laughing doves and 25 backyard poultry birds. The study utilized haemagglutination assay (HA) followed by haemagglutination inhibition (HI) tests on HA positive samples to screen field samples. Conventional reverse transcriptase polymerase chain reaction (RT-PCR) was conducted on the HI positives to characterize the NDV. This study revealed that of 134 dove samples screened, 88 (65.7 %) were HA positive. Of these HA positives subjected to HI testing, 37 (42.1 %) were HI positive. Interestingly, 21 (56.8 %) of the HI positives were also RT-PCR positive: 8 lentogenic, 12 velogenic, while one had both lentogenic and velogenic NDV. Comparatively, of the 50 chicken samples screened, 23 (46 %) were HA positive; and of these, HA positives subjected to HI testing, 16 (69.6 %) were HI positive. Only 4 (25 %) of the HI positives were RTPCR positive: 3 lentogenic and a velogenic NDV. From this study it was concluded that laughing doves were demonstrated to be infected with either lentogenic or velogenic NDV or both. The use of red blood adsorption-de-adsorption concentration of NDV enhanced the RT-PCR detection using the fusion gene primers NDV-F 4829 and NDV-R 5031. The detection of not only lentogenic but velogenic NDV in laughing doves poses a great risk to backyard poultry production.
