E-mail: gilmarferreiravita@yahoo.com.br The present survey was carried out at Zoology Laboratory, Universidade Federal Rural do Rio de Janeiro, and Animal Parasitology Sector, Universidade Estadual do Norte Fluminense Darcy Ribeiro, Rio de Janeiro state, from 2011 to 2012. The aim was to test in vitro and in vivo the effectiveness of the medicinal plant Chenopodium ambrosioides Linnaeus, 1786 (santa maria herb) regarding phytotherapeutic and homeopathic alternative methods to control endoparasites of Gallus gallus Linnaeus, 1758 (free range chicken), a serious problem affecting domestic poultry performance causing losses, retarded development, decreased food conversion rate and increase of susceptibility to infectious diseases. In vitro essay demonstrated high reduction rate on eggs eclosion inhibition (97.18%), and in vivo essay showed high fecal eggs counting reduction rate (91.67%). Presence of the genera Ascaridia (35.00%), Capillaria (30.00%), Heterakis (25.00%) and Strongyloides (10.00%) was displayed by this survey. The plant C. ambrosioides showed upper rates front traditional products (Thiabendalol/Mebendazol) as well as to those ones advocated by the Brazilian Ministry of Agriculture and the World Health Organization as effective.

RESUMO.- Vita G.F., Ferreira I., Costa Pereira M.A.V., Azevedo J.R., Sanavria A., Barbosa C.G., Gallo S.S.M. & Vasconcellos H.V.G. 2014. [Effectiveness of Chenopodium ambrosioides (santa maria herb) for controlling Gallus gallus (free range chicken) endoparasites.] Eficácia de Chenopodium ambrosioides (erva-de-santa-maria) no controle de endoparasitos de Gallus gallus (galinha caipira). Pesquisa Veterinária Brasileira 34(1):39-45.

E-mail: gilmarferreiravita@yahoo.com.br A pesquisa foi desenvolvida no Laboratório de Zoologia da Universidade Federal Rural do Rio de Janeiro e Setor de Parasitologia Animal da Universidade Estadual do Norte Fluminense Darcy Ribeiro, estado do Rio de Janeiro, no período de 2011 a 2012. O objetivo foi testar in vitro e in vivo a eficácia da planta medicinal Chenopodium ambrosioides Linnaeus, 1786 (erva-de-santa-maria), nas formas fitoterápica e homeopática, como meios alternativos para o controle de endoparasitos de Gallus gallus Linnaeus, 1758 (galinha caipira), um sério problema que afeta a criação e desempenho de aves domésticas, ocasionando morte quando muito intenso, retardo de crescimento, redução do 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). O ensaio in vitro demonstrou alta taxa de redução na inibição de eclosão de ovos (97,18%), e o ensaio in vivo, elevada taxa na redução da contagem de ovos nas fezes (91,67%). A pesquisa evidenciou a presença dos gêneros Ascaridia (35,00%), Capillaria (30,00%), Heterakis (25,00%) e Strongyloides (10,00%). C. 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.

Prevalence and geographical distribution of bovine eurytrematosis in cattle slaughtered in northern Paraná, Brazil. Pesquisa Veterinária Brasileira, 24(1):23-26.

E-mail: headleysa@cesumar.br A retrospective study of cattle slaughtered in northern Paraná during 2000 was performed to determine the prevalence and geographical distribution of bovine eurytrematosis (BE), as identified by the Federal Inspection Service (SIF). The cattle was from different regions of the State of Paraná; all regions had cattle parasitized by Eurytrema spp. BE was identified in 12.1% (12,534/103,411) of the total number of cattle inspected. Prevalence of animals parasitized by Eurytrema spp varied from 8.3% (Region G, São João do Caiuá, 1,069/12,914) to 40.5% (Region R, Ponta Grossa, 225/555). BE was more prevalent during the month of March (1.6) and markedly reduced during May (-2). A possible seasonal predominance of BE was identified: comparatively fewer cases occurred from April to August, while there was a peak from December to March. The study indicates that bovine eurytrematosis is hypoendemic and occurs in almost all geographical regions of the State of Paraná. The prevalence within this State is variable and may be directly related to factors of the biological cycle of the trematode, particularities of each region, and environmental conditions.
