Helmintos gastrintestinais em bovinos de corte no Acre.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: COSTA, A. L. da.
A pecuária no Estado do Acre desenvolve-se sob condições de um clima quente e úmido, fatores estes favoráveis ao desenvolvimento dos ciclos evolutiyos de parasitos diversos. As infecções parasitárias, dentre elas as causadas por helmintos gastrintestinais, têm se constituído em sério entrave ao aumento da produtividade e ao sucesso econômico na exploração bovina, mesmo naquela executada sob adequada tecnologia zootécnica. Com vista ao problema, a Unidade de Execução e Pesquisa de Âmbito Estadual de Rio Branco - UEPAE/Rio Branco-AC, desenvolveu um estudo preliminar para conhecimento da fauna helmintológica em bezerros de corte, visando determinar a. prevalência das espécies que parasitam os bovinos da região, o que, por certo, contribuirá para futuras...

Intestinal parasites of Alouatta caraya (Primates, Ceboidea): preliminary study in semi-captivity and in the wild in Argentina
Provedor de dados: Mastozoología Neotropical
Autores: Milozzi,Carola; Bruno,Gabriela; Cundom,Elisa; Mudry,Marta D; Navone,Graciela T.
Endoparasitic infections are common in nonhuman primates and important factors in regulating their natural populations. Primates are particularly vulnerable to the infections of directly transmitted parasites because they often live in close social groups that facilitate their transmission. The main objective of this study was to provide baseline data on gastrointestinal parasites of semi captive and wild howler monkeys Alouatta caraya troops from Argentina. We collected 110 fecal samples from 38 howler monkeys from four troops, two of them kept in semi-captivity at the CRMAN, Córdoba, and two wild troops from Las Lomas, Corrientes. We identified six species of parasites: four Protozoa, Giardia lamblia, Blastocystis hominis, Eimeria sp. and Entamoeba coli;...

Provedor de dados: Revista Brasileira de Ciência Avícola
Autores: Silva,GS da; Romera,DM; Fonseca,LEC; Meireles,MV.
Abstract The Brazilian poultry industry is an outstanding national and international agribusiness sector. Among the Brazilian states, São Paulo is the largest producer of commercial eggs and the fourth largest producer and exporter of chicken meat. Alternatively, semi-intensive and/or organic poultry production have also obtained a significant share of the domestic market as a result of consumer demand. Helminths affect the performance of the birds, causing significant direct or indirect losses. The objective of the present study was to identify the main helminth species present in chickens reared in 17 municipalities of the state of São Paulo. In total, 359 adult birds were investigated. The birds were reared in different housing systems and were obtained...

A new species of Andracantha Schmidt (Acanthocephala, Polymorphidae) parasite of Neotropical cormorants, Phalacrocorax brasilianus (Gmelin) (Aves, Phalacrocoracidae) from southern Brazil
Provedor de dados: Zoologia
Autores: Monteiro,Cassandra M.; Amato,José F. R.; Amato,Suzana B.
A new species of the genus Andracantha Schmidt, 1975, parasite of Neotropical cormorants, Phalacrocorax brasilianus (Gmelin, 1789), is described and compared to the other six species currently placed in the genus. The new species differs from the previously known species of Andracantha by having two inflations in the anterior region of the trunk and by having the testes in tandem in the central region of the body. These differences were also responsible for the diagnosis emendation of the genus now proposed. The orange pigmentation of the acanthocephalans recently collected from the intestine is documented for the first time in a species of this genus. This is the first record of adult specimens of any species of Andracantha in South America.

Autores: CHERNELA,Janet M.; THATCHER,Vernon E.
Studies were made of the intestinal parasites of Amerindian populations of the Uaupes River basin of Brazil. Three groups were sampled: 1) Tukano fisher-agriculturalists who live in permanent riverine villages; 2) Maku hunter-horticulturalists who live in close contact with the Tukano fishing villages; and 3) Maku who inhabit the forest interior and have little contact with permanent settlements. Fecal samples were collected from 498 individuals of which 220 were from the first group, 135 from de second and 143 from the third. The samples were analyzed by means of microflotation and centrifugal sedimentation. A total of 18 protozoan and helminth species were recorded based on the presence of cysts or eggs. These included five nematode species that could...

The anthelmintic resistance in small ruminants is a common problem and concern worldwide. The aim of this study was to verify anthelmintic treatment efficacy in naturally infected sheep. This study was conducted on nine herds that used the same anthelmintic management for over a year. In each farm, the animals were divided into two groups: untreated control group (n = 5) and treated (n = 10) according to the number of eggs per gram of feces (EPG). The treatment effect was checked based on EPG results and larval culture performed before treatment and 10 days after treatment. Significant differences were not observed (P&gt; 0.05) on EPG results between untreated and treated groups. The coproculture showed that the animals were infected primarily byHaemonchus...

Autores: FERREIRA,MAKSON M.; PASSADOR,RAFAEL J.; TAVARES-DIAS,MARCOS.
Abstract Abstract: This study compared the parasites community in Corydoras ephippifer, Corydoras melanistius, Corydoras amapaensis and Corydoras spilurus from tributaries from the Amapari River in State of Amapá (Brazil). A total of 151 fish of these four ornamental species were examined, of which 66.2% were parasitized by one or more species, and a total of 732 parasites were collected. Corydoras ephippifer (91.2%) and C. spilurus (98.8%) were the most parasitized hosts, while C. amapaensis (9.6%) was the least parasitized. A high similarity (≅ 75%) of parasite communities was found in the host species. Hosts were parasitized by Procamallanus (Spirocamallanus) inopinatus, Camallanus sp. and metacercariae of digeneans. The parasites had an aggregated...

ABSTRACT The population of wild animals is regulated by many biotic and abiotic factors, and parasites are a biotic factor that affects the dynamic and density of host populations. From 2002 to 2014, 62 wild animals from the biomes Pantanal, Amazon, and "Cerrado" (or Savanna), which died in attendance in the veterinary hospital or have been road-killed, underwent necropsy for parasitological examination. Overall, 36 species of parasites were identified from 24 host species. Among the parasites, the most prevalent order was Oxyurida (29.1%), followed by Strongylida (20.9%), Spirurida (19.4%), Ascaridida (16.2%), Pentastomida (3.2%), Echinostomida (3.2%), Gygantorhynchia (3.2%), Rhabditida (1.6%), Plagiorchiida (1.6%), and Monilimorfida (1.6%), especially...

Autores: Gallas,Moisés; Utz,Laura R. P.
Abstract: The acanthocephalan species Quadrigyrus torquatus Van Cleave, 1920 has been found in different hosts from South America, but recent papers have not focused on its morphology traits. Different species of Astyanax Baird &amp; Girard, 1854 were collected with seine nets between January 2017 and October 2017 in Pintada Island, Lake Guaíba, Porto Alegre city (30º17’11’’S and 51º18’01”W), Rio Grande do Sul State, Brazil. Acanthocephalans found in cysts were processed according to the techniques for the group. Specimens of Q. torquatus were identified based mainly in the morphology of proboscis hooks and trunk spines, and by the measurements made using light microscopy. Supplemental observations on the morphology of Q. torquatus were made for the first...

Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Melo,Osana Prado; Ramos,Renata Maria Arruda; Di Beneditto,Ana Paula Madeira.
The objectives of this work were to reporte the helminths of the marine tucuxi, Sotalia fluviatilis (Cetacea: Delphinidae) in northern Rio de Janeiro State; and to check if the infestation rate varied with the host characteristics (sex and maturity) and year seasons. From 1989 to 2002, 80 marine tucuxis that were by-caught in fisheries were examined and four parasites were recorded: Braunina cordiformis, Anisakis typica, Halocercus brasiliensis and Nasitrema sp. The parasitism in the marine tucuxi corroborated its feeding habits and there were no infestation rate differences between males and females, youngs and adults, as well as between year seasons. This work reports for the first time the occurrence of the genus Nasitrema in the marine tucuxi.
