RESUMEN

A case of infection with Dirofilaria immitis in a cat is reported here with clinical signs of apathy, anorexia, dyspnea, polypnea, slight dehydration and pale mucus membranes. The radiographic examination showed cardiomegaly, lobar arteries dilation of the cranial lobes and tortuosity, enlargement of the caudal lobar arteries. In the right lobe of the lung parenchyma, interstitial pulmonary opacification tending to alveolar opacification was seen. The clinical signs, the movements, and the morphology of the microfilariae in the direct examination of fresh blood, peripheral blood smear and Knott's modified test supported the diagnosis. We alert to the need for clinicians to consider feline heartworm diseases as a differential diagnosis in endemic areas when cats show respiratory signs.

Descreve-se um caso de infecção por Dirofilaria immitis em gato com sinais clínicos de apatia, anorexia, dispneia, polipneia, leve desidratação e mucosas pálidas. O exame radiográfico demonstrou cardiomegalia, dilatação da artéria lobar cranial e tortuosidade, alargamento dos lobos caudais da artéria lobar. No lobo direito do parênquima pulmonar, opacificação pulmonar intersticial tendendo à opacificação foi observada. O diagnóstico foi baseado nos sinais clínicos, nos movimentos e na morfologia das microfilárias detectadas no exame de sangue a fresco, no esfregaço de sangue periférico e no teste de Knott modificado. Alertou-se para a necessidade de os clínicos considerarem a dirofilariose felina como diagnóstico diferencial em áreas endêmicas quando os gatos apresentam sinais respiratórios.

RESUMEN

Brazilian poultry production is growing, mainly due to the cost and benefit that chicken meat provides. The importance of free-range chickens and the susceptibility, to which they are exposed, makes it necessary to know about gastrointestinal parasites and the consequences that large infections can cause for them as such as weight loss. The present study aimed to determine the occurrence of gastrointestinal parasites in free-range hens raised in an extensive regime in the municipality of Santa Rita, state of Maranhão, Brazil. The studied population was composed of adult chickens (Gallus gallus domesticus) acquired from slaughterhouses in the region. The gastrointestinal organs of each chicken were separated and subsequently conditioned in flasks containing Railliet and Henrys solution and sent to the laboratory, to be analyzed and processed. Of the 100 chickens examined, 227 specimens of helminthes were identified, with a frequency of 32.6% for nematodes and 67.4% for cestodes. Among the nematode the following parasites were identified: Ascaridia galli (27.03%); Heterakis gallinarum (48.65%) and Subulura spp. (24, 32%). Raillietina echinobothrida (100%) was the only cestoda identified. The average infection rate by species of parasite was 1.18 for A. galli, 2.22 for H. gallinarum, 1.06 for Subulura spp. and 9.00 for R. echinobothrida. It is concluded that free-range chickens are parasitized by nematodes and cestoda.(AU)

RESUMEN

Estudos sobre parasitos gastrintestinais de primatas não-humanos em situação de cativeiro são importantes na rotina clínica de animais silvestres para o manejo sanitário das colônias e para evitar a disseminação de parasitos entre tratadores e animais, pois muitos destes parasitos são causadores de zoonoses. Neste contexto, objetivou-se identificar por exames coproparasitológicos instares parasitários gastrintestinais em amostras fecais de primatas neotropicais no Criadouro Conservacionista Ararajuba do Ipê, Estado do Maranhão, Brasil e identificar qual tipo de recinto (gaiola suspensa ou recinto com piso de terra) os animais se apresentaram mais parasitados. Foram analisadas 20 amostras fecais de primatas neotropicais, sendo 18 em pools e duas amostras individuais (P. monachus e S. apella), uma coleta no período seco e outra no chuvoso. Totalizando 69 primatas neotropicais de 12 espécies diferentes sob estudo. As técnicas utilizadas foram de sedimentação espontânea e flutuação e observados em microscopia de luz. Foram identificados ovos de Hymenolepidiidae, Strongyloides spp., Trichuris spp., Protospirura spp., Ascaris spp., Ancylostomatidae e oocistos de coccídeos.

Studies on gastrointestinal parasites of non-human primates in captivity are important in the clinic of wild animals for the sanitary management of colonies and to prevent the spread of parasites between keepers and animals, as many of these parasites are the cause of zoonoses. In this context, the objective was to identify parasitic gastrointestinal instar coproparasitological exams in fecal samples from neotropical primates at the Ararajuba de Ipê Conservation Center, Maranhão State, Brazil and to identify the type of enclosure (hanging cage or enclosure with earth floor) the animals were more parasitized. Twenty fecal samples from neotropical primates were analyzed, 18 in pools and two individual samples (P. monachus and S. apella), one in the dry season and other in the rainy season. Totaling 69 neotropical primates of 12 different species under study. The techniques used were spontaneous sedimentation and fluctuation and observed under light microscopy. Hymenolepidiidae eggs, Strongyloides spp., Trichuris spp., Protospirura spp., Ascaris spp., Ancylostomatidae and coccidian oocysts. Most cages were suspended (0.5 m from the soil) and did not allow feces to accumulate. The results demonstrate a diversity of gastrointestinal parasites in neotropical primates incaptivity. The most common parasites found in the study are not characterized as zoonotic, being important to becareful when handling closed packages and in the soil of neotropical primate enclosures.(AU)

RESUMEN

Feather samples were obtained from the following Psittaciformes birds: Amazona amazonica, Amazona aestiva, Aratinga jandaya, Brotogeris spp., Ara ararauna and Ara chloropterus (total of 37 individuals). These birds were housed at the Wild Animal Screening Center of Maranhão, São Luís, Brazil. Four feathers were taken from the following regions: head, back, wings, belly/breast, thighs, and tail/covert. Mites were found on 17 birds (45.94%). Astigmatid mites belonging to the genera Fainalges (Xolalgidae), Chiasmalges (Psoroptoididae) and Tanyaralichus (Pterolichidae) were identified. The highest dominance coefficient was for the mite Fainalges sp. (DC= 96.29). Chiasmalges sp. was obtained only from Ara chloropterus, and Tanyaralichus was found in A. aestiva. The genus Fainalges was obtained from all the species of Psittaciformes studied, except for A. ararauna. In evaluating mite density according to body region, statistical differences were found between the back and wing regions (P= 0.041), back and thighs (P= 0.02), wings and tail (P= 0.002), belly and tail (P= 0.031) and thighs and tail (P= 0.001). The morphological variations observed in Fainalges spp. suggested the existence of three species that probably have not been described yet. This was the first record of the genus Tanyaralichus in Brazil.(AU)

As amostras de penas foram obtidas das seguintes aves da ordem Psittaciformes: Amazona amazonica, Amazona aestiva, Aratinga jandaya, Brotogeris spp., Ara ararauna e Ara chloropterus, totalizando 37 aves, alojadas no Centro de Triagem de Animais Silvestres do Maranhão, São Luís, Brasil. Colheram-se quatro penas de cada uma das regiões: cabeça, dorso, asas, ventre/peito, coxas e cauda/crisso. Verificou-se a presença de ácaros em 17 aves (45,94%). Foram identificados ácaros Astigmata, pertencentes aos gêneros Fainalges (Xolalgidae), Chiasmalges (Psoroptoididae) e Tanyaralichus (Pterolichidae), sendo o maior coeficiente de dominância correspondente ao ácaro Fainalges sp. (CD= 96,29). Chiasmalges sp. foi obtido apenas de Ara chloropterus, e Tanyaralichus foi encontrado em A. amazônica. O gênero Fainalges foi obtido de todas as espécies de Psittaciformes estudadas, exceto em A. ararauna. Na avaliação da densidade de ácaros por região do corpo, verificou-se diferença estatística entre regiões dorsal e asas (P= 0,041), dorsal e coxas (P= 0,02), asas e caudal (P=0,002), ventral e caudal (P= 0,031) e coxas e caudal (P= 0,001). Variações morfológicas observadas em Fainalges spp., sugerem a existência de três espécies provavelmente ainda não descritas. Este é o primeiro registro do gênero Tanyaralichus no Brasil.(AU)

RESUMEN

The objective was to identify the gastrointestinal parasites of wild animals received by the Center for Screening of Wild Animals from São Luis, Maranhão State, Brazil. The fecal samples were collected from 297 animals, of which 150 (50.5%) were birds, 132 (44.5%) mammals and 15 (5%) reptiles. A total of 262 samples (227 individual and 35 pools) were analyzed by the method of sedimentation and flotation, 102 animals were parasitized by helminthes and/or protozoa, 39 of which belonged to the order Primate, 18 to the Carnivorous order and 12 to the Psittaciformes order. The mammals had the greatest diversity of eggs of gastrointestinal parasites: Strongyloides sp., hookworm type, Spirometra sp., Ascaris sp., Trichuris vulpis, Capillaria sp., Strongyloidea, Ancylostomidae , taenid and oocysts of coccidian. In the samples of birds were diagnosed eggs of the genera Dispharynx, Ascaridia, Echinostoma and oocyst of coccidian. In the reptiles, the number of gastrointestinal parasites was low, being identified oocyst of coccidian in three jiboia (Boa constrictor) and Capillaria sp. in an iguana (Iguana iguana). It was concluded that wild animals act as hosts for various species of parasites and to establish the dynamics and parasitic fauna of these animals at the screening center is an excellent alternative for studies ex situ.(AU)

Objetivou-se identificar os parasitos gastrintestinais de animais silvestres recepcionados pelo Centro de Triagem de Animais Silvestres de São Luís, Maranhão. As amostras fecais foram coletadas entre agosto de 2006 a julho de 2008, totalizando 297 animais, dos quais 150 (50,5%) foram aves, 132 (44,5%) mamíferos e 15 (5%) répteis. Do total de 262 amostras (227 individuais e 35 pools) analisadas pelo método de sedimentação simples e flutuação, 102 animais estavam parasitados por helmintos e/ou protozoários, sendo que, 39 pertenciam à ordem Primata, 18 à Carnívora e 12 à Psittaciforme. Os mamíferos apresentaram a maior diversidade de ovos de parasitos gastrintestinais, como Strongyloides sp., ancilostomídeo, Spirometra sp., Ascaris sp., Trichuris vulpis, Capillaria sp., Strongyloidea, Ancilostomídeo e tenideos, além de oocistos de coccídios. Em amostras de aves identificaram-se ovos dos gêneros Dispharynx, Ascaridia, Echinostoma, e também de oocistos de coccídeos. Nos répteis, o número de parasitos gastrintestinais foi baixo, sendo identificados oocisto de coccídeo em três jiboias (Boa constrictor) e Capillaria sp. em uma iguana (Iguana iguana). Concluiu-se que animais silvestres atuam como hospedeiros para diversas espécies de parasitos, e estabelecer a riqueza e a dinâmica da fauna parasitária desses animais nos centros de triagem é uma excelente alternativa para a realização de estudos ex situ.(AU)
