25. Ectoparasites of bats (Chiroptera, Furipteridae), with a description of a new species of Synthesiostrebla Townsend (Diptera, Streblidae) from Brazil
Ectoparasitos de morcegos (Chiroptera, Furipteridae), com a descrição de uma nova espécie de Synthesiostrebla Townsend (Diptera, Streblidae) do Brasil. Os poucos dados sobre ectoparasitismo em morcegos furipterídeos são restritos a moscas (Streblidae). Somente três espécies de estreblídeos eram conhecidas antes desse trabalho: Trichobius pallidus (Cu

26. Quantitative study of Trichodina heterodentata (Ciliophora: Mobilia) infrapopulations infesting tadpoles of a Brazilian endemic toad Rhinella pombali (Anura: Bufonidae)
In this work we investigated the quantitative aspects of the relationship between Rhinella pombali (Baldissera, Caramaschi & Haddad, 2004) tadpoles and their trichodinid ectoparasites. Specimens were collected from a small stream located at an agricultural area between rainforest fragments in southeastern Brazil. A total of 80 tadpoles were investigated. Tri

27. Ectoparasitic insects (Diptera: Streblidae and Siphonaptera: Ischnopsyllidae) of bats from Iquitos and surrounding areas (Loreto, Peru)
Based on specimens collected from bats of different families, we add new species and extend the known ecological distribution and host associations of insect ectoparasites of bats in Peru. New information is provided for the distribution of 26 species of parasites (25 Diptera and 1 Siphonaptera: Ischnopsyllidae). Four species (Neotrichobius ectophyllae, Stre

28. Community structure of lice (Insecta: Phthiraptera) from two sympatric gull species: kelp gull (Larus dominicanus) and Franklin's Gull (Larus pipixcan) in Talcahuano, Chile
A total of 1,177 lice of four species were collected from 124 kelp gulls (Larus dominicanus) and 137 lice of the same four species from 60 Franklin's gulls (Larus pipixcan). The louse Saemundssonia lari (O Fabricius) (Phthiraptera: Philopteridae) was the most numerous on both gull species, with infestation rates of 4.9 on kelp gulls and 1.8 on Franklin's gul

29. Bat flies on phyllostomid hosts in the Cerrado region: component community, prevalence and intensity of parasitism
Streblidae flies are specialised parasites of bat hosts, mainly phyllostomids. There is a high richness of streblids in the savannah-like Cerrado region; however, there is little quantitative data available in parasitological indices. Here, we describe the component community, prevalence and intensity of a streblid infestation on a phyllostomid bat assemblag

30. Ectoparasitos em preás (Galea spixii Wagler, 1831) cativos no Semiárido do Rio Grande do Norte, Brasil / Ectoparasites in guinea pigs (Galea spixii Wagler, 1831) captive in semiarid region of Rio Grande do Norte, Brazil
Os roedores silvestres quando criados em cativeiro podem ser acometidos por algumas doenças de natureza infecciosa ou parasitária, o que afeta a sanidade e bem-estar destes animais. Nesta linha, esse trabalho objetivou identificar a ectofauna natural do preá Galea spixii criado nas condições de cativeiro no semiárido do Rio Grande do Norte e estudar o

31. Produção de proteína animal de qualidade com sustentabilidade: controle racional das parasitoses dos bovinos.
In Brazil as in the rest of the world, sectors of production and commercialization of animal originated foods, are changing to attend the two highst marcket demands: competitivity and quality. These exigencies are specially related to healthy foods. So the use of products that leave residues in meat and/or milk is going to be more restritive in an animal pro

32. Ectoparasite occurrence associated with males and females of wild rodents Oligoryzomys flavescens (Waterhouse) and Akodon azarae (Fischer) (Rodentia: Cricetidae: Sigmodontinae) in the Punta Lara wetlands, Argentina
The objective of this research was to study infestation parameters and indexes of ectoparasites associated with each sex of the wild rodents Oligoryzomys flavescens (Waterhouse) andAkodon azarae (Fischer) in the Punta Lara wetlands, Argentina. A trend towards higher mean abundance (MA) and ectoparasite specific richness was observed in males of O. flavescens

33. Biologia do Amblyomma parvum, Aragão 1908 (Acari: Ixodidae) utilizando-se diferentes hospedeiros em condições de laboratório
Ticks are obligatory hematophagous ectoparasites and are thus infectious disease vectors for both humans and animals. To understand the epidemiology of tick-borne infectious diseases it is essential to know the life cycle of ticks. Amblyomma parvum is a Neotropical tick and its life cycle is poorly understood. In this work the biology of A. parvum is describ

34. Helmintos e artrópodes de Vanellus chilensis (Molina, 1782), quero-quero, da região sul do Rio Grande do Sul / Helmintos e artrópodes de Vanellus chilensis (Molina, 1782), quero-quero, da região sul do Rio Grande do Sul / Identification of helminths and arthropods in Vanellus chilensis (Molina, 1782) (Charadriiformes: Charadriidae), lapwing, in the south region of the Rio Grande do Sul state / Identification of helminths and arthropods in Vanellus chilensis (Molina, 1782) (Charadriiformes: Charadriidae), lapwing, in the south region of the Rio Grande do Sul state
Vanellus chilensis is a bird species of the family Charadriidae distributed across Central and South America. Despite its high abundance and broad distribution, there are few records of parasites on this species. Aiming to identify the helminths and arthropods that parasitize V. chilensis in southern Brazil, twenty eight birds were necropsied. For collection

35. Parasitos metazoários de cetáceos da costa nordeste do Brasil. / Metazoan parasites of cetaceans of the northeast coast of Brazil.
Cetaceans are parasitized by a wide diversity of endo and ectoparasites in various tissues, organs and cavities. Some species are related to causes of strandings and mortality of dolphins and whales. In addition to knowledge about the pathological effects of these organisms, their importance in ecological and evolutionary studies is highlighted. The parasiti

36. Notes on the hematology of free-living Phrynops geoffroanus (Testudines: Chelidae) in polluted rivers of Southeastern Brazil
Phrynops geoffroanus (Schweigger, 1812) is the freshwater turtle with the widest geographical distribution in South America. During 2006, physical examination and hematological evaluation were performed on free-ranging turtles from two polluted rivers, the Piracicaba River (n = 51) and its tributary Piracicamirim (n = 42), in southeastern Brazil.
