Abstract(s)
A ornitologia desportiva é uma prática que surgiu com o crescente interesse do homem pelas aves que encontrava na travessia dos mares e conquista de novos territórios. Em Portugal o primeiro clube somente dedicado à criação e exposição de aves canoras e ornamentais, criado em 1935 e intitulado atualmente de Associação de Avicultores de Portugal, apresenta até hoje atividade, sendo um meio importante de divulgação de informação e organização de eventos relacionados com a modalidade. No estudo foram incluídas 89 amostras frescas de fezes de aves ou grupos de aves criadas em contexto desportivo, das ordens Passeriformes e Psitaciformes, para identificação de parasitas gastrointestinais. As técnicas coprológicas utilizadas foram a Flutuação de Willis, Sedimentação natural em meio saturado, Mini-FLOTAC e esfregaço fecal com coloração de Ziehl-Neelsen modificada. A prevalência total de infeção parasitária foi de 19,1% (n=17), estando incluídos nos resultados positivos parasitas gastrointestinais como coccidias, Ascaridia spp. e Cryptosporidium spp. As aves da ordem Passeriformes apresentaram uma prevalência de infeção de 18,31% (13/71) e as aves da ordem Psitaciformes apresentaram uma prevalência de infeção de 22,22% (4/18). Relativamente à densidade populacional, as amostras provenientes de grupos de aves apresentaram uma prevalência de infeção superior de 19,35% (12/62) em relação às amostras individuais com 18,52% (10/54). E no que diz respeito à faixa etária, as amostras provenientes de animais ou grupos de animais com mais de um ano de idade apresentaram uma prevalência de infeção inferior de 18,75% (12/64) em relação a amostras provenientes de grupos de animais com crias com 20% (5/25). Para além das informações referentes às amostras, foram documentados dados relativos aos hábitos de maneio de 16 criadores de aves ornamentais, bem como o seu conhecimento geral sobre doenças parasitárias. Metade desconhecia que fezes representam um meio de transmissão de infeções parasitárias e todos administravam empiricamente substâncias antiparasitárias, antibióticas e/ou antifúngicas. Os resultados obtidos vêm assim reiterar a importância do envolvimento do Médico Veterinário no meio da ornitologia desportiva, sendo crucial a realização de análises coprológicas de rotina e a desparasitação adequada, tanto das aves residentes nos plantéis, como das recém-adquiridas
ABSTRACT - Identification of gastrointestinal parasites in ornamental birds under competitive conditions and survey of their breeders in Portugal - Competitive ornithology is an activity that emerged with the growing interest of humans in birds encountered during sea crossings and the conquest of new territories. In Portugal, the first club dedicated solely to the breeding and exhibition of songbirds and ornamental birds, founded in 1935 and currently known as the Association of Aviculturists of Portugal, remains active today, serving as an important means of disseminating information and organizing events in the field. In this study, 89 fresh faecal samples from birds or groups of birds raised in the context of competitive ornithology, belonging to the orders Passeriformes and Psittaciformes, were included for gastrointestinal parasite identification. The coprological techniques used were Willis flotation method, natural sedimentation, Mini-FLOTAC, and faecal smear with modified Ziehl-Neelsen staining. The overall prevalence of parasitic infection was 19,1% (n=17), with gastrointestinal parasites such as coccidia, Ascaridia spp., and Cryptosporidium spp. found among the positive results. Samples from Passeriformes birds showed an infection prevalence of 18,31% (13/71), while samples from Psittaciformes birds presented an infection prevalence of 22,22% (4/18). Regarding population density, samples from bird groups showed a higher infection prevalence of 19,35% (12/62) compared to individual samples with a prevalence of 18,52% (10/54). And concerning age range, samples from animals or groups of animals older than one year had a lower infection prevalence of 18,75% (12/64), than samples from groups of animals with offspring with a prevalence of 20% (5/25). In addition to the sample-related information, data on the management practices of 16 ornamental bird breeders and their general knowledge about parasitic diseases was documented. Half of the breeders were unaware that faeces represent a means of parasitic transmission, and all of them implemented empirical therapy using antiparasitic, antibiotic, and/or antifungal substances. The obtained results reinforce the importance of the involvement of a Veterinarian in the field of competitive ornithology, emphasizing the need for routine coprological analyses and appropriate deworming in both resident birds of the flocks and newly acquired ones
