Gastrointestinal parasites of exotic birds living in captivity in the state of Sergipe, Northeastern Brazil / Parasitos gastrointestinais de aves exóticas que vivem em cativeiro no estado de Sergipe, Nordeste do Brasil

Brazil has a wide diversity of exotic birds that were brought to this country during the European colonization. These animals are kept in captivity and, in some cases, in inadequate facilities, which may facilitate the introduction of pathogens, including gastrointestinal parasites. The purpose of this study was to identify the main gastrointestinal parasites that affect exotic birds living in captivity in the state of Sergipe, Northeastern Brazil. Fecal samples (n = 362) from exotic birds were analyzed by direct examination and by the Willis-Mollay technique. Eggs of Amidostomum sp., Ascaridia sp., Capillarinae, Heterakis sp., Trichostrongylidae, and oocysts of coccidians were identified in nine different bird species. This is the first report in Brazil of infection by Ascaridia sp. and Heterakis sp. in Nymphicus hollandicus; by Trichostrongylidae in Serinus canaria and Streptopelia risoria.(AU)

O Brasil possui uma grande diversidade de aves exóticas que foram trazidas para o país durante a colonização europeia. Estes animais são mantidos em cativeiros, os quais muitas vezes são inadequados, proporcionando o surgimento de doenças provocadas por parasitas gastrointestinais. Objetivou-se neste estudo, realizar avaliação coproparasitológica de fezes de aves ornamentais mantidas em cativeiros no estado de Sergipe, região Nordeste do Brasil. Amostras fecais (n= 362) de aves exóticas foram analisadas através do exame direto a fresco e técnica de Willis-Mollay. Ovos de Amidostomum sp., Ascaridia sp., Capillarinae, Heterakis sp., Trichostrongylidae, e oocistos de coccídeos foram encontrados em nove diferentes espécies de aves. Aqui, destacamos, os primeiros registros no Brasil de Ascaridia sp. e Heterakis sp., parasitando Nymphicus hollandicus; Trichostrongilidae em Serinus canaria e Streptopelia risoria.(AU)

Eficácia de Chenopodium ambrosioides (erva-de-santa-maria) no controle de endoparasitos de Coturnix japônica (codorna japonesa) / Effectiveness of Chenopodium ambrosioides (santa maria herb) for controlling Coturnix japonica (japanese quail) endoparasites

O objetivo foi testar in vitro e in vivo a eficácia da planta medicinal Chenopodium ambrosioidesLinnaeus, 1786 (erva-de-santa-maria), nas formas fitoterápica e homeopática, como meios alternativos para o controle de endoparasitos de Coturnix japonica Temminck & Schlegel, 1849 (codorna japonesa), um sério problema que afeta a criação e desempenho de aves domésticas, ocasionando morte quando muito intenso, retardo de crescimento, redução de índice de conversão alimentar e aumento na suscetibilidade às doenças infecciosas. As metodologias utilizadas foram preconizadas por Coles et al. (1992), creditada pela World Association for the Advancement of Veterinary Parasitology (WAAVP). A pesquisa evidenciou a presença dos gêneros Ascaridiae Eimeria. O ensaio in vitro demonstrou alta taxa de redução na inibição de eclosão de ovos de Ascaridiasp. (100,00%) e significativa taxa de redução na destruição de oocistos de Eimeriasp. (47,06%). O ensaio in vivodemonstrou alta taxa de redução na contagem de ovos de Ascaridiasp. nas fezes (100,00%) e expressiva taxa de redução na contagem de oocistos de Eimeriasp. nas fezes (60,33%). Chenopodium ambrosioides mostrou em certos momentos superioridade frente ao produto tradicional (Thiabendazole/Mebendazole) e índices superiores aos preconizados pelo Ministério da Agricultura do Brasil e Organização Mundial da Saúde como indicativos de eficácia.(AU)

The aim was in vitro and in vivo to test the effectiveness of Chenopodium ambrosioides Linnaeus, 1786 (santa maria herb) medicinal plant, in regard to phytotherapeutic and homeopathic forms as alternative methods to control Coturnix japonica Temminck & Schlegel, 1849 (japanese quail) endoparasites. The parasitosis is a serious problem affecting domestic poultry raising and performance causing death, delay in grow, food conversion rate reduction and increase of susceptibility to infectious diseases. Methodologies were advocated by Coles et al. (1992), corroborated by World Association for the Advancement of Veterinary Parasitology (WAAVP). Presence of the genera Ascaridia and Eimeria was displayed by this survey. In vitro essay demonstrated high reduction rate on eggs eclosion inhibition of Ascaridia sp. (100.00%) and significant reduction rate on oocyst destruction of Eimeria sp. (47.06%). In vivo essay demonstrated high fecal egg counting reduction rate of Ascaridia sp. (100.00%) and expressive fecal oocyst counting reduction rate of Eimeriasp. (60.33%). C. ambrosioides showed upper rates front traditional product (Thiabendalol/Mebendazol) as well as to those ones advocated by the Brazilian Ministry of Agriculturel and the World Health Organization as effectiveness indicative.(AU)

Atividade anti-helmíntica de plantas em frangos de corte naturalmente infectados com Ascaridia galli / Anthelminthic activity of plants in broiler chickens naturally infected with Ascaridia galli

The anthelminthic activity of four plants - Allium sativum (garlic), Punica granatum (pomegranate), Tynnanthus labiatus (liana-carnation) and Cocus nucifera (coconut) with the activity of mebendazole was compared. Seventy Hubbard chickens, naturally infected with Ascarídia galli, divided in 5 groups of 10 chichens plus a control group (not treated, n=20) were used in the experiment. The vegetable matter was used in the forms of aqueous extract, juice and triturated, administered by probe or incorporated to the diet, in the doses of 2, 3 and 10g/kg/day, for three days. A non parametric test was used to evaluate the anthelminthic effect of the plants. The eliminations of A. galli for the garlic, pomegranate, liana-carnation, coconut and mebendazole were: 9.7; 6.6, 16.7; 19.0 and 99.0%, respectively. The results showed that those plants do not have anthelminthic activity.(AU)
