Parasitismo por Proatractis sp em jabuti piranga / Parasitism due to Proatractis sp. in red-footed tortoise

Tortoises are chelonians characterized by cylindrical and strong legs adapted to terrestrial life. These animals have gradually gained more space within the segment of wild animal pets. Parasitism is the relationship between living beings in which there is advantage to one species, parasite, and disadvantage to a greater or lesser degree to another, host. It may also be divided into endoparasitism or ectoparasitism if the parasite inhabits the interior of the host organism or only its outer surface, respectively. Atractidae is a family of endoparasites with direct cycle. Their eggs hatch in utero and third stage larvae are released. A male adult specimen of red-footed tortoise was treated in the Wild Animal Sector of the Jerônimo Dix-Huit Rosado Maia Veterinary Hospital of the Federal Rural University of the Semi-Arid. During the physical examination the animal defecated and when inspecting its feces it was possible to observe with the naked eye the presence of large quantity of small helminths. Samples were collected and analyzed in an electron microscope through the direct examination technique through which it was possible to identify the parasite.

Blood metabolites as predictors to evaluate the body condition of Neopelma pallescens (Passeriformes: Pipridae) in northeastern Brazil

Body condition is an important ecological attribute that can provide a measure of the energy stored by an animal or population. Body condition is traditionally ascertained with morphometric body condition indices (BCIs), but some researchers have used various physiological and biochemical parameters as predictors of body condition. This study aimed to test reliable biochemical predictors of body condition in individuals of Neopelma pallescens (Lafresnaye, 1853), found in an Atlantic forest patch. For this purpose we examined the relationship between body condition and the concentrations of blood glucose and ketones. We also verified correlations between blood metabolite concentrations and ecological variables, including time of day, seasons, breeding periods, and ectoparasite infestation. Birds were captured with mist nets at Reserva Biológica de Guaribas, state of Paraíba, Brazil. Blood samples were analyzed with a portable glucometer. The correlation between glucose and ketones was negative. Both metabolites showed significant variations according to time of day. Glucose levels were higher in the afternoon and ketones levels were higher in the morning, suggesting a correlation with daily food intake. The BCI of non-breeding birds was negatively correlated with glucose concentrations. However, the correlation between glucose and the BCI of incubating birds was a positive. Ketone bodies did not correlate with body condition. In relation to ectoparasite infestation, only ketones showed significant results, presenting a higher concentration in infested individuals. Glucose is a good predictor of the BCI of incubating birds since it correlates positively with it. However, the lack of seasonal variations in metabolites indicates that the nutritional status of tropical birds does not change when food is abundant. Thus, we conclude that glucose and ketone bodies can predict the nutritional status of birds but in a context-dependent fashion.

Ectocommensal and ectoparasites in goldfish Carassius auratus (Linnaeus, 1758) in farmed in the State of São Paulo

Concomitant infections by several parasitic genera are rare, very debilitating and often lethal to fish reared under commercial breeding conditions. Were describe a multiple and concurrent parasite infestation in cultured goldfish Carassius auratus with skin damage (nodules and/or ulceration). Fish with skin lesions underwent necropsy, and the skin and gills were scraped and examined. Histopathological examination with Hematoxylin-Eosin and Giemsa stain, and an ultrastructure study using transmission and scanning electron microscopy were conducted. In the skin, we identified multiple-parasite infestations by Gyrodactylidae, Epistylis sp., Trichodina sp., Ichthyophthirius multifiliis, Tetrahymena sp. and Ichthyobodo necator,associated with epithelial cell hyperplasia and epidermal sloughing. Although no gross lesions were observed, were identified a large number of parasites in the gills (Epistylis sp., Piscinoodinium sp., Ichthyophthirius multifiliis, Trichodina sp., Apiosoma sp., Hexamitasp. and cysts of a trematode digenean). The observed trematodes were not identified. The associated microscopic lesions were epithelial hypertrophic and hyperplasic and exhibited fusion of secondary lamellae and epithelial cell detachment. This is the first description of a protozoan Vorticella sp. parasitizing goldfish in Brazil. Multiple ectoparasitism by protozoa and Platyhelminthes, with or without apparent tissue damage, can be fatal for goldfish raised on farms with poor management.

A infestação concomitante por vários gêneros de parasitas é uma condição rara, debilitante e letal para os peixes e está geralmente associada aos problemas ambientais e de manejo. Com o objetivo de descrever os ectoparasitos presentes em kinguios Carassius auratus com lesões cutâneas, cultivados em fazenda comercial, foram analisados 30 exemplares de peixes por esfregaços de pele lesionada e de brânquias; exame histopatológico de tecidos corados pela técnica de Hematoxilina-Eosina e Giemsa e estudo ultraestrutural por microscopia eletrônica de transmissão e varredura de tecidos coletados após necropsia. Nas lesões cutâneas, foram observados os parasitos: Gyrodactylidae, Epistylis sp., Trichodina sp., Ichthyophthirius multifiliis, Tetrahymena sp. e Ichthyobodo necator, associados à hiperplasia epitelial, descamação epidérmica e presença de infiltrado inflamatório. A infestação das brânquias, mesmo sem lesão macroscópica, evidenciou Epistylissp., Piscinoodinium sp., I. multifiliis, Trichodina sp., Apiosoma sp., Hexamita sp. e cistos de trematódeo associados à hipertrofia e hiperplasia epitelial, fusão de lamelas secundárias, descamação epitelial e presença de infiltrado inflamatório. Os trematódeos observados não foram identificados. É a primeira descrição do protozoário Vorticella sp. parasitando kinguios no Brasil. O ectoparasitismo múltiplo por protozoários e platelmintos, com ou sem lesão aparente, pode ser fatal em peixes cultivados em condições ambientais precárias.

Fauna parasitológica de Zungaro zungaro Humeboldt e Valenciennes, 1821 provenientes da Amazônia Brasileira

Zungaro zungaro é um peixe que compõe o grupo dos bagres e possui a carne apreciada por consumidores em distintas regiões do Brasil. Investigações a respeito de parasitos de peixes com importância econômica no país tem se destacado no meio científico, principalmente porque há registros de helmintos que representam problemas de saúde pública. Assim, no presente trabalho, vinte e cinco peixes da referida espécie foram capturados ao longo do rio Araguaia no período de junho a outubro de 2015, por pescadores devidamente licenciados para realização de três pesquisas distintas. Os peixes tiveram vísceras gastrointestinais, nadadeiras, olhos, brânquias, muco, fígado e baço removidos e acondicionados em frascos individuais com formol a 10%, para investigação de helmintos e ectoparasitos com cálculos de seus respectivos percentuais de infecção. Os parasitos foram coletados com auxílio de um microscópio estereoscópico e mantidos em líquido Railliet & Henry até a identificação. Durante a pesquisa de anisaquídeos foram observados três exemplares de larvas Hysterothylacium sp. com percentual de infecção 8%, intensidade média 1,5, abundância 0,12 e variação de intensidade 1-2, sendo o primeiro relato deste helminto em Zungaro zungaro com os cálculos de indicadores de infecção na bacia Tocantins-Araguaia. As larvas de Hysterothylacium sp. representam problemas de saúde pública, carecendo de estudos aprofundados a respeito de suas características, requerendo medidas sanitárias no manejo pós-abate, bem como cuidado no descarte de vísceras e no preparo do alimento. Durante a pesquisa de helmintos, vinte e três peixes apresentaram infecção (92%), totalizando 135 parasitos coletados de estômago, intestino, vesícula, baço e fígado, com registro dos nematódeos Cucullanus patoi, C. pseudoplatystomae, C. pinnai e Hysterothylacium sp., o trematódeo Allocreadium sp., o cestódeo Monticellia siluri e o pentastomídeo Sebekia sp., que apresentaram percentuais de infecção 12%, 24%, 28%, 8%, 76%, 24% e 8%, respectivamente. A pesquisa revelou o primeiro registro do cestódeo Monticellia siluri em Zungaro zungaro e do trematódeo Allocredium sp. em bagres pimelodídeos no Brasil. No decurso da investigação a cerca de ectoparasitismo, dois peixes apresentaram parasitismo por Miracetyma piraya e Argulus sp. que perfizeram 19 parasitos recuperados de brânquias do Zungaro zungaro sendo que o percentual de infecção para ambos ectoparasitos foi de 4% e as intensidade 1 e 18 para Miracetyma piraya e Argulus sp. respectivamente. Com o aumento das pisciculturas no rio Araguaia, principalmente em relação aos projetos de implantação de tanques-rede, torna-se necessário o conhecimento de espécies helmintológicas existentes nessa bacia e o acompanhamento da evolução desse parasitismo nas espécies nativas, tendo em vista a elevada densidade as quais estas espécies serão submetidas.

Zungaro zungaro is a fish that makes up the group of catfish and has the meat appreciated by consumers in different regions of Brazil. Investigations regarding parasites of fish of economic importance in the country have been prominent in the scientific environment, mainly because there are records of helminths that represent public health problems. Thus, in the present study, twenty-five fish of this species were captured along the Araguaia River from June to October 2015, by fishermen duly licensed to conduct three different surveys. The fish had gastrointestinal viscera, fins, eyes, gills, mucus, liver and spleen removed and stored in individual flasks with 10% formaldehyde to investigate helminths and ectoparasites with calculations of their respective percentages of infection. The parasites were collected with the help of a stereoscopic microscope and kept in Railliet & Henry liquid until identification. Three Hysterothylacium sp. Larvae were observed during the aniseed research. with an infection rate of 8%, mean intensity 1.5, abundance of 0.12 and variation of intensity of 1-2, being the first report of this helminth in Zungaro zungaro with calculations of infection indicators in the Tocantins-Araguaia basin. The larvae of Hysterothylacium sp.represent public health problems, lacking in-depth studies on their characteristics, requiring sanitary measures in post-slaughter management, as well as care in the discarding of viscera and in the preparation of food. During the study of helminths, twenty - three fish presented infection (92%), totaling 135 parasites collected from the stomach, intestine, vesicle, spleen and liver, with nematodes Cucullanus patoi, C. pseudoplatystomae, C. pinnai and Hysterothylacium sp. , Allocreadium sp., Monticellia siluri cestode and Sebekia sp. pentastomid, which presented infection rates of 12%, 24%, 28%, 8%, 76%, 24% and 8%, respectively. The research revealed the first record of the Monticellia siluri cestode in Zungaro zungaro and the trematódeo Allocredium sp. in pimelodida catfish in Brazil. In the course of the research about ectoparasitism, two fish had parasitism by Miracetyma piraya and Argulus sp. which resulted in 19 parasites recovered from Zungaro zungaro gills. The percentage of infection for both ectoparasites was 4% and the intensity 1 and 18 for Miracetyma piraya and Argulus sp.respectively. With the increase of the fishery in the Araguaia river, mainly in relation to the projects of implantation of net tanks, it is necessary to know the helminth species existing in this basin and the monitoring of the evolution of this parasitism in

Ectoparasitismo em uma assembléia de morcegos em um fragmento florestal no estado do Acre, Brasil / Ectoparasitism in a bats assembly from forest fragment at the Acre State, Brazil

A abundância de ectoparasitos em morcegos pode ser influenciada através de características associadas ao hospedeiro, tal como abrigo, tamanho do corpo, sexo, idade, ou sistema social. Estudos sobre o tema na Amazônia, especialmente a brasileira, são escassos. A área de estudo foi o Parque Zoobotânico (PZ), com tamanho aproximado de 150ha, localizado na cidade de Rio Branco-Ac. Os morcegos foram capturados com o auxílio de redes de neblina, as quais ficavam abertas das 18h00min às 22h00min, durante três dias/mês, ao longo de um ano. Os animais capturados foram colocados em sacos de pano e levados ao laboratório para coleta e identificação de ectoparasitos. Foram capturados 61 indivíduos de 11 espécies de morcegos. Dos morcegos capturados, 33 apresentaram pelo menos uma espécie de díptero ectoparasita. O morcego com o maior número de ectoparasitas coletados foi um indivíduo macho da espécie Phyllostomus elongatus, com 13 moscas ectoparasitas da espécie Trichobius costalimai. O grau de parasitismo parece estar sendo influenciado pelo microclima e pelos hábitos de cada espécie, tais como o tipo de abrigo utilizado e a formação de colônias.

The abundance of ectoparasites in bats can be influenced through characteristics associated to the host, just as shelter, size of the body, sex, age, or social system. Studies on thetheme in the Amazonian, especially the Brazilian rainforest, they are scarce. The study area was at the Zoobotanical Park (ZP), with approximate 150ha size, located in the Rio Branco city ­Acre/Brazil. The bats were captured with the mist-nets, which wereopen of the 6p.m.at 10p.m., during three days/months, along one year. The captured animals were put in cloth sacks and taken to the laboratory for collection and identification of ectoparasites batflies. Sixty one individuals of 11 species of bats were captured. Of the captured bats, 33 presented at least one type of ectoparasites batfly. The bat with the largest number of collected ectoparasites was a male individual of the Phyllostomus elongatusspecies, with 13 ectoparasites batflies of the species Trichobius costalimai. The degree of parasitism seems to be being influenced by the microclimate and for the habits of each species, such as the type of used shelter and the formation of colonies.

HELMINTOFAUNA MONOGENÉTICA E AS TÁTICAS REPRODUTIVAS DA BIQUARA Haemulon plumierii (Lacepède, 1802)

Haemulon plumierii são peixes costeiros que habitam águas desde a Baía de Chesapeake - EUA, Golfo do México, Caribe e toda a costa do Brasil. Os peixes são os vertebrados aquáticos que apresentam os maiores índices de parasitismo e usam diferentes táticas reprodutivas em sua estratégia de vida para maximizar a reprodução e garantir a sobrevivência dos seus descendentes até a idade adulta. O presente trabalho verificou se o ectoparasitismo por monogenéticos pode influenciar as táticas reprodutivas de H. plumierii nas águas marinhas no Norte do Oceano Atlântico Sudoeste (4º 5057S e 37º5136O), próximo ao Rio Grande do Norte/Brasil, para isso, realizou-se a pesquisa parasitária de monogenéticos e o estudo das táticas reprodutivas de H. plumierii. Foram capturados 240 exemplares de hospedeiros H. plumierii no período de agosto de 2015 a julho de 2016, com amplitudes de peso total entre 84,5 a 517,5g e comprimento total de 175 a 315mm. Os Monogenéticos parasitaram 106 peixes H. plumierii entre 240 examinados, sendo coletados 162 parasitos que estavam distribuídos em duas subclasses: Monopisthocotylea e Polyopisthocotylea. Monopisthocotylea da família Capsalidae nos gêneros Encotyllabe (75 nas brânquias e 9 no tegumento) e Entobdella (1 nas brânquias e 17 no tegumento); Polyopisthocotylea na família Diclidophoridae no gênero Choricotyle (51 nas brânquias e 9 no tegumento). H. plumierii foi identificado como um novo hospedeiro para os monogenéticos Encotyllabe sp., Entobdella hipoglossi, e Choricotyle sp., sendo o primeiro registro do gênero Entobdella na família Haemulidae. Os parasitos monogenéticos apresentaram uma maior preferência parasitária pelas brânquias, apresentando baixos índices ecológicos parasitários. Determinou-se que H. plumierii são peixes estrategistas sazonais no qual os machos apresentam maior peso total, comprimento total e número em relação as fêmeas, contudo não ocorreram diferenças significativas. Registrou-se que a espécie H. plumierii possui as seguintes táticas reprodutivas: crescimento do tipo alométrico negativo indicando um incremento corporal maior em comprimento do que em peso; independente deste estádio imaturo (jovens) foi verificado macroscopicamente que os adultos possuem três estádios de desenvolvimento gonadal (em maturação, maduro e esvaziado) durante o ciclo reprodutivo; este animal alterou sua estratégia reprodutiva iniciando o desenvolvimento reprodutivo com precocidade onde a fecundidade absoluta foi de 52.123 ovócitos com um tipo de desova sincrônico em mais de dois grupos; o período reprodutivo está compreendido durante todo o ano com maior ocorrência em dois momentos nos meses de março a junho e o segundo de agosto a outubro. O presente trabalho registrou que a espécie Haemulon plumierii é parasitado por monogenéticos Monopisthocotylea e Polyopisthocotylea com baixos índices de prevalência, intensidade média e abundância média, e que H. plumierii é um estrategista sazonal onde suas táticas reprodutivas não sofreram influência pelo parasitismo de monogenéticos nas condições de baixos índices ecológicos parasitários.

Haemulon plumierii are coastal fish that inhabit waters from the Chesapeake Bay - US, Gulf of Mexico, Caribbean and the entire coast of Brazil. Fish are the aquatic vertebrates that have the highest rates of parasitism and use different reproductive tactics in their life strategy to maximize reproduction and ensure the survival of their offspring to adulthood. The present work verified whether the ectoparasitism by monogenetic can influence the reproductive tactics of H. plumierii in marine waters in the North Atlantic Ocean Southwest (4º 50'57 ''S and 37º51'36''O), near the Rio Grande do Norte / Brazil, for that, the parasitic research of monogenetic was carried out and the study of the reproductive tactics of H. Plumierii. 240 copies were captured of H. plumierii hosts in the period from august 2015 to july 2016, with amplitudes of total weight between 84.5 to 517.5g and total length of 175 to 315mm. Monogenetics parasitized 106 H. plumierii fish among 240 examined, and 162 parasites were collected that were distributed in two subclasses: Monopisthocotylea and Polyopisthocotylea. Monopisthocotylea of the family Capsalidae in the genus Encotyllabe (75 in the gills and 9 in the skin) and Entobdella (1 in the gills and 17 in the skin); Polyopisthocotylea in the family Diclidophoridae in the genus Choricotyle (51 in the gills and 9 in the skin). H. plumierii was identified as a new host for the monogenéticos Encotyllabe sp., Entobdella hipoglossi, and Choricotyle sp., being the first record of the genus Entobdella in the family Haemulidae. The monogenetic parasites had a higher parasite preference for the gills, presenting low parasitic ecological indices. It was determined that H. plumierii are seasonal strategist fish in which males present greater total weight, total length and number in relation to females, however, there were no significant differences. It was recorded that the H. plumierii species has the following reproductive tactics: growth of the negative allometric type indicating a greater body increase in length than in weight; independent of this immature (young) stage it was verified macroscopically that adults have three stages of gonadal development (in maturation, mature and emptied) during the reproductive cycle; this animal altered its reproductive strategy, initiating reproductive development with precocity where the absolute fecundity was 52,123 oocytes with a synchronous spawning type in more than two groups; the reproductive period is comprised throughout the year with the highest occurrence in two moments in the months of march to june and the second of august to October. The present work reported that the species Haemulon plumierii is parasitized by monogenetic Monopisthocotylea and Polyopisthocotylea with low prevalence rates, medium intensity and average abundance, and that H. plumierii is a seasonal strategist where his reproductive tactics were not influenced by the parasitism of monogenetics in conditions of low parasitic ecological indices.

Ectoparasitos em preás (Galea spixii Wagler, 1831) cativos no semiárido do Rio Grande do Norte / Ectoparasites in guinea pigs (Galea spixii Wagler, 1831) in captivity in the semiarid region of Rio Grande do Norte, Brazil

Os roedores silvestres quando criados em cativeiro podem ser acometidos por ectoparasitos que afetam a sua sanidade. Este 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 comportamento da dinâmica comportamental do ectoparasitismo mais prevalente. Utilizou-se 40 espécimes de spixii cativos do Centro de Multiplicação de Animais Silvestres da Universidade Federal Rural do Semi-Árido. Os exemplares foram anestesiados e examinados para busca de ectoparasitos, durante os meses de março a outubro de 2010. Os preás estudados apresentaram Amblyomma sp., Demodex sp. e Gliricola quadrisetosa. Os dados de frequência de G. quadrisetosa, espécie de maior prevalência, revelaram que a média de piolhos recuperados nas distintas áreas corporais, foi maior para exemplares fêmeas (p=0,0498). O período climático não influenciou na frequência de G. quadrisetosa recuperada dos animais (p>0,05). Da ectofauna identificada em G. spixii, notifica-se Demodex sp. como primeiro registro neste roedor nas condições semiáridas do Brasil. Os dados sugerem que a área corporal e o período não interferiram na infra população de Gliricola quadrisetosa encontrada em Galea spixii.(AU)

Wild rodents in captivity can be attacked by ectoparasites which affect their health. This study aimed to identify the natural ectofauna of the guinea pig Galea spixii Wagler, 1831 in captivity in the semiarid region of Rio Grande do Norte and to study the behavioral dynamics of the most prevalent ectoparasitism. Specimens (n=40) of G. spixii in captivity in the Center for Wild Animal Multiplication (Centro de Multiplicação de Animais Silvestres da Universidade Federal Rural do Semi-Árido) were anesthetized from March to October 2010 and examined searching for ectoparasites. The guinea pigs presented Amblyomma sp. (Koch, 1844), Demodex sp. (Owen, 1843) and Gliricola quadrisetosa (Ewing, 1924). The frequency of data of G. quadrisetosa, the most prevalent species in the study, showed that the mean of lice collected in the different body parts was higher in females (p=0,0498). The climatic period did not influence the frequency of G. quadrisetosa collected from the animals (p>0.05). Demodex sp. was the first record of ectofauna identified in G. spixii in semiarid conditions in Brazil. The data indicate that the body surface area and the climatic period did not influence the infra-population of Gliricola quadrisetosa found in Galea spixii.(AU)

Determinação de hemogregarina em Boa constrictor constrictor mantidos em cativeiro / Determination of hemogregarine in Boa constrictor constrictor kept in captivity

O presente estudo teve como objetivo determinar a presença de hemogregarina em boídeos mantidos em cativeiro no Estado do Pará, bem como, relacionar a hemoparasitose com pre-disposição sexual, alterações clínicas e hematológicas e a presença de ectoparasitos. Esta pesquisa teve autorização do Sistema de Autorização e Informação em Biodiversidade do Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis para ser realizado. Utilizaram-se 19 serpentes da família Boidae mantidas em cativeiro, pertencentes ao "Museu Paraense Emilio Goeldi" (Belém/PA) e "Sítio Xerimbabo" (Santo Antônio do Tauá/PA). A pesquisa de hemogregarina foi realizada em esfregaços sanguíneos examinados no aumento de 400x, enquanto que a parasitemia foi determinada contando- se 550 hemácias em aumento de 1000x. Do total de animais estudados (n=19), nove encontraram-se parasitados (47,36%), não havendo correlação entre presença de hemogregarina, pré-disposição sexual, alterações clínicas e hematológicas nas serpentes hospedeiras. A correlação da hemoparasitose foi detectada apenas quanto à presença de ectoparasitas nas serpentes, no entanto, estudos adicionais são necessários para verificar a prevalência de hemogregarinas em animais mantidos em cativeiro no Estado do Pará, visto que, existe grande lacuna de dados na literatura veterinária especializada no que diz respeito à fauna da região amazônica.(AU)

We aimed to determine hemogregarines presence in snakes of the Boidae family kept in captivity in Pará (PA), Brazil, and to relate it with sex, clinical and hematological and ectoparasitism. This study had authorization from Sisbio/IBAMA to be done. Nineteen Boa constrictor snakes were used, belonging to the "Museu Paraense Emílio Goeldi" (Belém/ PA) and "Xerimbabo Farm" (Santo Antônio do Tauá/PA). Blood smears were examined with 400x magnification, while the parasitemia percentage was determined by counting 550 red blood cells with 1000x magnification. From the snakes studied (n=19), nine were parasitized (47.36%) and there was no correlation between hemogregarines presence, sex, clinical and hematological changes. Hemoparasitosis correlation was detected only with the ectoparasites presence; however further studies are needed to determine the real hemogregarines prevalence in snakes kept in captivity in Pará, since there is a huge gap of data in the veterinary specialized literature about the fauna of the Amazon region.(AU)

Dípteros ectoparasitas (Insecta, Diptera) em morcegos (Chiroptera, Mammalia) na Reserva Biológica das Perobas Paraná, Brasil

Streblidae and Nycteribiidae are exclusively found in association with bats. The main objective of the present work was to investigate the diversity of bat flies found in bats from the Perobas Biological Reserve, state of Paraná, Brazil. The work was performed in the months of May, June and August, 2008 and February, March and April, 2009. For the capture of bats, 32 mist nets were used, totalizing a capture effort of 43,520 m²h. Ectoparasite capture was made manually or through the aid of a forceps. Specimens were conserved in 70% alcohol and identified with the aid of a stereoscopic microscope. Data was analyzed by means of a non parametric Bootstrap and descriptive statistics. Bat flies species identified were: Aspidoptera falcata Wenzel, 1976, Megistopoda proxima (Séguy, 1926), Megistopoda aranea (Coquillett, 1899), Paratrichobius longicrus (Miranda Ribeiro, 1907), Trichobius tiptoni Wenzel, 1976 and Basilia quadrosae Graciolli & Moura, 2005. Estimated richness curve indicates tendency to the occurrence of other ectoparasitic species in the conservational unit, since a horizontal asymptote was not achieved. The data obtained is corroborated by the respective data in other Brazilian regions and contribute with information about the group diversity in the Atlantic Forest Biome from the northwest of Paraná.

Streblidae e Nycteribiidae são encontradas exclusivamente em associação com morcegos. Este trabalho teve como objetivo investigar a diversidade de insetos ectoparasitas encontrados em morcegos da Reserva Biológica das Perobas, Estado do Paraná, Brasil. O trabalho foi realizado nos meses de maio, junho e agosto de 2008 e fevereiro, março e abril de 2009. Para a captura dos morcegos, foram utilizadas 32 redes-de-neblina, totalizando esforço de captura de 43.520m².h. A coleta de ectoparasitas foi feita manualmente ou com auxílio de pinça reta de ponta fina. Os espécimes foram conservados em álcool 70% e identificados com auxílio de microscópio estereoscópico. Os dados foram analisados por meio do estimador não paramétrico Bootstrap e estatística descritiva. As espécies de ectoparasitas identificadas foram: Aspidoptera falcata Wenzel, 1976, Megistopoda proxima (Séguy, 1926), Megistopoda aranea (Coquillett, 1899), Paratrichobius longicrus (Miranda Ribeiro, 1907), Trichobius tiptoni Wenzel, 1976 e Basilia quadrosae Graciolli & Moura, 2005. A curva de riqueza estimada indicou tendência à ocorrência de outras espécies de ectoparasitas na unidade de conservação, haja vista que não foi alcançada a assíntota horizontal. Os dados obtidos corroboram com os verificados em outras regiões do Brasil e contribuem com as informações sobre a diversidade do grupo no bioma Mata Atlântica do noroeste do Paraná.

Ocorrência de miíases em animais de companhia no Distrito Federal, brasilimação cardiopulmonar / cerebral (RCPC) em cães / Occurrence of myiasis in pets from the Federal District, in Brazil

Background: Myiasis is one of the main causes of infestation by Diptera larvae in animals and human beings. This parasitic disease is frequently diagnosed at veterinary and medical practices. It is classified according to its anatomical location in the host or to its dependency relations and parasitic occurrence. In Brazil, the two diptera species with the highest myiasis incidence in domestic animals are Cochliomyia hominivorax (Calliphoridae) and Dermatobia hominis (Oestridae). These ectoparasites are primarily found in dogs and secondarily in cats, and they are often associated with omission or mistreatment by the owner. This study describes myiasis cases and the main predisposing factors in domestic animals that occurred in 2009 in the Federal District, Brazil. Materials, Methods & Results: Between January and December 2009, veterinary practitioners from 90 small animal practices were requested to supply the larvae collected from clinical myiasis cases. The larvae were kept alive inside biological containers containing vermiculite to preserve their integrity during transportation. Data on the collection month, age, gender, breed, color and type of coat, as well as lesion site, myiasis type and dwelling type were obtained. The larvae were identified in laboratory and then kept inside incubators, fed on rotten bovine meat during 24h. The resulting flies were again identified and sexed. Then the absolute and relative proportions of the clinical cases were obtained, based on the epidemiological factors and respective parasites. Forty cases were recorded (39 of which were dogs and one was a cat). Cochliomyia hominivorax was the most abundant parasite, with 37 cases observed in dogs and only one in a cat. The other two myiasis cases were caused by Lucilia eximia and Musca domestica. In dogs, the highest occurrence of myiasis was observed in males, especially in German Sheepdogs and Cocker Spaniels. The predominant anatomical sites of the disease in dogs were the front limbs and tail. The period in which the disease occurred most frequently was between March and May, period which corresponds to the rainy season in the Brazilian Cerrado. Dogs living in houses within urban areas had the highest parasitism occurrence. Discussion: Myiasis in companion animals is a common finding throughout practices in Brazil and around the world. However, this situation has been under control in North American countries, especially after erradication of myiases caused by C. hominivorax in bovines, which represented great economic losses. Therefore, the incidence of the parasitism in dogs and cats was reduced. In Brazil, obligatory and facultative cutaneous myiases in dogs and cats are caused by omission and mistreatment by the owner. The results presented in this study corroborate the characteristics of neotropical myiases in the Southeast and South region of Brazil in relation to the incidence period and preferential host characteristics, except that the disease has a preference for male light-colored animals, being predominantly observed on the hind limbs. New cases were observed in dogs, particularly in Central Brazil, such as the facultative cutaneous myiasis cases caused by Lucilia eximia and Musca domestica.

Profile of the dermathopatic dogs and cats attended at Universidade Federal Fluminense´s Policlínica Veterinária in the period of March 1998 to February 2004, Niterói, RJ / Perfil dos cães e gatos dermatopatas atendidos na Policlínica da Faculdade de Veterinária da UFF março / 98 fevereiro / 2004, Niterói, RJ

A dermatologia é uma das áreas de grande importância na clínica médica veterinária segundo diversos estudos. Nestapesquisa foram avaliados as suspeitas clínicas dermatológicas mais comuns e o perfil dos animais portadores quanto àespécie, raça, idade e sexo, por meio da análise do livro de registro dos atendimentos da Policlínica Veterinária da UniversidadeFederal Fluminense (UFF) e das fichas propedêuticas dos pacientes atendidos com queixas dermatológicas. Os caninosapresentaram, em ordem decrescente, dermatites bacterianas e abscessos, dermatites alérgicas e ectoparasitoses,enquanto os felinos foram atendidos devido a ectoparasitoses; dermatites fúngicas; dermatites bacterianas e abscessos.Na sua maioria, os cães eram machos, de raça definida e com idade entre 1 e 5 anos, já os felinos eram mestiços, do sexofeminino e na mesma faixa etária dos caninos.Observou-se que as espécies diferem com relação às afecções dermatológicasmais comuns e que as ectoparasitoses ainda são relevantes no atendimento veterinário. A prevalência de espécie, raça,idade e sexo dos animais são possivelmente influenciados pela população animal domiciliada.(AU)

At present, dermatology has been reveled as very important in veterinary medicine according to several studies. In this research it was verified the most common dermatological disorders in clinical practice and the patients profile regarding specie, breed, age and gender, through the analysis of the UFF´s Policlínica Veterinaria´s registry book of the clinical attendance and the clinical files of the animals with dermatologic complaints. The dogs were mostly diagnosed, in a decreasing order, with bacterial dermatitis and abscesses, allergic dermatitis, e ectoparasitism, while the cats were attended due ectoparasitism; fungal dermatoses; bacterial dermatitis and abscesses. The dogs were mostly male, pure breed and at the age between 1 and 5 years old. The cats were mostly mixed breed, female and between 1 and 5 years old. The most common dermatosis was different to dogs and cats. Ectoparasitisms still are very important to the veterinary practice. The prevalence of specie, breed, age and gender in the dermatological diagnostic is possibly affected by the normal owned animal population.(AU)
