“…In Argentina, broiler chicken flocks were evaluated and 25% of flocks were shown infected but no correlation was found between nematodes and coccidian infections (De Franceschi et al, 2008). Previous studies in Brazil, have found broiler flocks infected by Ascaridia galli in 10/17 municipalities of São Paulo (Da Silva et al, 2018), in free-range flocks in the neighboring state (Paraná), with 45% infected (Vieira et al, 2015), and in Santa Catarina in 21.7% (Quadros et al, 2015). In our study, we show that raising broilers in Minas Gerais, previously shown to naturally occur A galli by Mendes et al (1976) and in our unpublished extension service, especially for longer and without preventive medication, may lead to highly significant infection.…”

Industrial broilers raised on helminthic medication-free feed were diagnosed with a severe disease caused by Ascaridia galli, characterized by intestinal hemorrhage and obstruction. A. galli was identified based on the morphological features of the nematode. Broilers were raised for a longer period (63 days) for weight recovery, grouped as stunted (n=500), had low body score and had fetid diarrhea. The duodenumjejunum segment was the most severely affected with obstruction and had localized accumulation of gas. The intestinal mucosa was severely congested with petechial and suffusive hemorrhages. The outbreak resulted in morbidity of about 10% and mortality of up to 4% and was associated to the absence of preventive medication on feed and slack biosecurity. The reemergence of A. galli is discussed in view of the alternative poultry management and raising conditions for drug free and welfare.

“…Ascaridia galli e Heterakis gallinarum já foram identificados em galinhas caipiras (Gallus gallus domesticus), através da técnica de flutuação e de centrífugo-flutuação [3,7,16]. Utilizando estas técnicas de flutuação, há relatos da presença de pelo menos um helminto parasitando mais de 80% de galinhas-d'angola [3].…”

Ocorrência de Ascaridia galli e Heterakis gallinarum em galinha-d'angola (Numida meleagris) no estado de Rondônia, BrasilOccurrence of Ascaridia galli and Heterakis gallinarum in Guinea Fowl (Numida meleagris) in the State of Rondônia, Brazil ABSTRACT Background: Parasitic diseases are among the problems that most affect birds. The Ascaridia spp. is one of the genera which is responsible for the main infections, and the Ascaridia. galli is the most frequent species found in birds. The Ascaridia spp. egg is oval and present a smooth shell which could be mistaken with the Heterakis gallinarum eggs, once they are the most frequent parasites in birds. Therefore, this case report describes the occurrence of Ascaridia galli and Heterakis gallinarum in a guinea fowl (Numida meleagris) feces and gut. Case: In January 2017, rain season in northern Brazil, a visit was performed to a free range avian breeding property in the municipality of São Miguel do Guaporé in the state of Rondônia, Brazilian Amazonian Region. The property breeds two chicken species: Gallus gallus domesticus and Numida meleagris as well as one quail species. The problem was related to the guinea fowl breeding which was composed by 50 adults and 45 young birds about two or three weeks old. All 45 young guinea fowl were presenting various clinical signs, which included: yellowish catarrhal diarrhea, isolation, loss of appetite, body weight, ruffled feathers, drooping wings and sternal prominence. All animals that presented the clinical signs as ruffled feathers, drooping wings and sternal prominence died on an average of 24 h and the mortality was of 65.9% (29/45). Subsequently, a three-week old bird corpse was necropsied, and it was observed that its intestines presented a large amount of endoparasites besides presenting thickening. As there were a lot of helminths, they were collected along with the intestinal content for examination. The parasitological examinations of the feces were performed by Willys Molay's technique. As a result of the fluctuation technique, were observed and identified large quantities of Heterakis gallinarum and Ascaridia galli eggs. The adult worms of H. gallinarum and A. galli were identified using dichotomous key. Discussion: Ascaridia galli and Heterakis gallinarum infection were reported in guinea fowl in a free range chicken breeding property in the municipality of São Miguel do Guaporé in the state of Rondônia, Brazilian Amazonian Region. Ascaridia galli and Heterakis gallinarum eggs have already been identified in free-range chickens (Gallus gallus domesticus) by flotation techniques, as Willys Mollay and Faust and they are the main species of helminths housed by chickens. However, these parasites are not commonly reported in guinea fowl worldwide, especially in the Numida meleagris species. Regarding necropsy, intestinal wall thickening is generally a common finding which has been reported in chickens, however it is not commonly reported in guinea fowl. Additionally, the presence of clinical signs of nematode parasitos...

“…Os gêneros observados nesta pesquisa, Ascaridia, Capillaria e Heterakis, são também relatados na maioria dos estudos que versam sobre parasitismo gastrintestinal de aves domésticas [2,22,23,24,25,26], podendo ser considerados como os de maior ocorrência em infecções parasitárias dessas espécies. Vita et al (2014) [25] mencionou que a ocorrência de endoparasitos em G. gallus de regimes extensivo ou semi-extensivo, provavelmente está relacionada ao contato direto com o solo, utilização de fontes hídricas não tratáveis, e sobrevivência prolongada de ovos desses parasitos no meio ambiente [27,28,29]. Nesta pesquisa constatou-se que onde as aves habitavam circulavam outras espécies animais (silvestres ou domésticas), e que a falta de higiene, chão enlameado, contato com as fezes, água não tratada, foram fatores que favoreceram a proliferação das doenças parasitárias.…”

Fluminense Darcy Ribeiro (UENF), no período de 2015 a 2018. O objetivo foi testar in vitro e in vivo a eficácia da planta medicinal Spigelia anthelmia Linnaeus, nas formas fitoterápica e homeopática, como meios alternativos para o controle de endoparasitos de Gallus gallus Linnaeus (1758), 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. Para o experimento in vitro, foi realizado teste de inibição de eclosão de ovos e teste de inibição do desenvolvimento larvar; e, para o experimento in vivo, foi realizado teste de redução da contagem de ovos nas fezes. As metodologias utilizadas para execução dos testes foram creditadas pela World Association for the Advancement of Veterinary Parasitology (WAAVP), organização referência para testes anti-helmínticos. S. anthelmia demonstrou eficácia nos experimentos in vitro e in vivo, com valores máximos de 55,00% (homeopatia) e 67,00% (fitoterapia), no teste de inibição de eclosão de ovos, 82,00% (homeopatia) e 75,00% (fitoterapia), no teste de inibição do desenvolvimento larvar, e 81,82% (homeopatia) e 75,00% (fitoterapia), no teste de redução da contagem de ovos nas fezes. A planta apresentou valor superior ao produto tradicional utilizado (Febendazol) no experimento in vitro, ficando dentro dos índices propostos pela WAAVP, Ministério da Agricultura do Brasil e Organização Mundial da Saúde, como indicativos de eficácia.
