“…Nestes estudos, foram identificadas várias espécies do gênero Capillaria parasitando aves (Hofstatter & Guaraldo, 2015;Marietto-Gonçalves et al, 2009;Ritchie et al, 1997;Vicente et al, 1997). Contudo, até o momento, nenhum trabalho citou o gênero parasitando a P. chalybea.…”

Por vários anos a andorinha-grande (Progne chalybea) utiliza como dormitório coletivo o centro da cidade de Chapecó no período que antecede a migração, oportunidade única para se obter dados ecológicos da espécie. A aproximação de aves de vida livre com o ser humano pode ser uma preocupação devido a possibilidade de transmissão de patógenos, assim como, as aves podem ser contaminadas por patógenos humanos ou de animais domésticos. Esse estudo verificou a prevalência de endoparasitas nas amostras fecais de P. chalybea, coletadas no dormitório, no período de abril a maio de 2019. Os dados preliminares sugerem o parasitismo por Capillaria e coccídeos (oocistos sugestivos dos gêneros Eimeria e/ou Isospora). Sabe-se que a ocorrência de endoparasitos pode ser utilizada como parâmetro sanitário. Portanto, é importante a continuidade dos trabalhos a fim de determinar quais espécies de parasitos a P. chalybea possui. Ademais, estes dados podem ser utilizados em inferências de saúde das aves, visto que elas prestam um importante serviço ecológico no controle de insetos vetores.

“…Co-workers who are veterinary practitioners and also work with captive birds, strictly refrained from contact with the above-mentioned facilities in the weeks before sampling. We considered these precautions mandatory, since parasites are common in captive birds, probably as an effect of captivity [ 86 , 89 – 91 ]. We took special precautions to avoid both the contamination of samples and spreading of disease into wild populations during sampling.…”

Can the intake of antiparasitic secondary metabolites explain the low prevalence of hemoparasites among wild Psittaciformes?

BackgroundParasites can exert selection pressure on their hosts through effects on survival, on reproductive success, on sexually selected ornament, with important ecological and evolutionary consequences, such as changes in population viability. Consequently, hemoparasites have become the focus of recent avian studies. Infection varies significantly among taxa. Various factors might explain the differences in infection among taxa, including habitat, climate, host density, the presence of vectors, life history and immune defence. Feeding behaviour can also be relevant both through increased exposure to vectors and consumption of secondary metabolites with preventative or therapeutic effects that can reduce parasite load. However, the latter has been little investigated. Psittaciformes (parrots and cockatoos) are a good model to investigate these topics, as they are known to use biological control against ectoparasites and to feed on toxic food. We investigated the presence of avian malaria parasites (Plasmodium), intracellular haemosporidians (Haemoproteus, Leucocytozoon), unicellular flagellate protozoans (Trypanosoma) and microfilariae in 19 Psittaciformes species from a range of habitats in the Indo-Malayan, Australasian and Neotropical regions. We gathered additional data on hemoparasites in wild Psittaciformes from the literature. We considered factors that may control the presence of hemoparasites in the Psittaciformes, compiling information on diet, habitat, and climate. Furthermore, we investigated the role of diet in providing antiparasitic secondary metabolites that could be used as self-medication to reduce parasite load.ResultsWe found hemoparasites in only two of 19 species sampled. Among them, all species that consume at least one food item known for its secondary metabolites with antimalarial, trypanocidal or general antiparasitic properties, were free from hemoparasites. In contrast, the infected parrots do not consume food items with antimalarial or even general antiparasitic properties. We found that the two infected species in this study consumed omnivorous diets. When we combined our data with data from studies previously investigating blood parasites in wild parrots, the positive relationship between omnivorous diets and hemoparasite infestation was confirmed. Individuals from open habitats were less infected than those from forests.ConclusionsThe consumption of food items known for their secondary metabolites with antimalarial, trypanocidal or general antiparasitic properties, as well as the higher proportion of infected species among omnivorous parrots, could explain the low prevalence of hemoparasites reported in many vertebrates.Electronic supplementary materialThe online version of this article (10.1186/s13071-018-2940-3) contains supplementary material, which is available to authorized users.

“…Em galinhas o período pré-patente varia de cinco a seis semanas e em pintinhos cerca de oito semanas. Os vermes na fase adulta podem viver, aproximadamente, um ano(TAYLOR et al, 2016).As espécies desse gênero são frequentemente relatadas em aves cativas da ordem psittaciformes, como araras e periquitos, sendo um dos parasitas mais importantes de papagaios mantidos em cativeiro (HOFSTATTER eGUARALDO, 2015). SegundoMelo et al (2013), as espécies de Ascaridia mais comuns são A. platyceri e A. hermafrodita.…”
