| Fifty-six opossums (Didelphis aurita) were captured on the campus of Universidade Federal Rural do Rio de Janeiro, Seropédica county, Rio de Janeiro state, in order to investigate the occurrence of Borrelia sp among them in relation with the study of spirochaetemia and its ectoparasites. Blood tests were made through dark field and phase contrast microscopy, as well as the obtainment of blood smears. Smears were stained with Giemsa stain, which did not prove efficacy. There was no relation between results obtained through blood tests (13 opossum positive for Borreliasp.), and this technique (two positive animals). Parasitaemia studies of 37 animals kept in captivity as well as of several recaptures in which animals once negative proved to be positive days... |

| This study evaluated the haematological parameters of the hybrid surubim (Pseudoplatystoma corruscans x P. reticulatum) farmed in intensive and semi intensive system. A total of 240 fish were examined, 120 from fish farm and 120 from a semi-intensive for comparison between the hot and cold season. The water quality was weekly measured to evaluate the influence of environmental conditions on the haematology. Fish from intensive system showed hematocrit and white blood cell count (WBC) higher in hot season while the total plasmatic protein, hemoglobin concentration, mean corpuscular hemoglobin concentration (MCHC) and mean corpuscular volume (MCV) were higher in cold season. In fish from semi intensive system, the red blood cells count (RBC) and total... |

| Este estudo avaliou a eficácia da heparina sódica e do EDTA tripotássico como anticoagulantes e seus efeitos sobre os parâmetros hematológicos de tambaqui (Colossoma macropomum). Foram utilizados dez indivíduos de tambaqui com médias de 384,9 ± 85,71 g de peso e 27,90 ± 2,10 cm de comprimento total para avaliação da heparina 5.000 UI e 100 UI, bem como do K3EDTA 10%. Foram analisados a inibição da coagulação por 10 h, eritrograma e teste de fragilidade osmótica dos eritrócitos. Os resultados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey (P < 0,05). Heparina 5000 UI, heparina 100 UI e K3EDTA 10% foram eficazes na prevenção da coagulação por mais de 10 h, no entanto o EDTA tripotássico causou hemólise desde os... |

| Este estudo avaliou o efeito da heparina 100UI e do Na2EDTA nas concentrações de 3, 5 e 10% sobre a coagulação sanguínea e os parâmetros hematológicos de surubim híbrido. Foram utilizados 10 peixes, com peso médio de 386,7±24,3g e comprimento total médio de 38,7±6,4cm, para colheita das amostras sanguíneas e determinação do percentual do hematócrito, teor de proteínas plasmáticas totais e teste de fragilidade osmótica dos eritrócitos (FOE). Os dados foram submetidos à análise de variância, e as médias foram comparadas pelo teste de Tukey, a 5% de probabilidade. A coagulação foi eficientemente inibida quando utilizado o Na2EDTA; já as amostras com heparina coagularam 10 horas após a coleta. Houve aumento na fragilidade osmótica dos eritrócitos (P<0,01),... |

| ABSTRACT: The aim of this study was to evaluate the histological changes in the liver of thirty-five Gymnotusspp. parasitized by endohelminths collected between April 2012 to October 2013 in commercial bait fish farming of Pantanal basin. Histological cuts of 7µm were stained with hematoxylin-eosin for parasites research and liver changes and have also been submitted to the Perls histochemical method for evaluation of hemosiderosis (Fe+++) based on the incidence degree and severity of change (Grade I, II and III) and tests for the presence of central melanomacrophages. Parasites identified were: Brevimulticaecumsp. with a prevalence of 22,9%, Eustrongylidessp 17,1%, Contracaecumtype I 68,7%, Contracaecumtype II 5,7%, Contracaecumtype III 5,7% and larvae of... |

| Abstract: The objective of this work was to describe the host-Epistylis sp. relationship during infestation on farmed fish. Five Nile tilapia (Oreochromis niloticus) and ten hybrid surubim catfish (Pseudoplatystoma reticulatum x P. corruscans), all diseased, were used for in vivo morphological analysis of sessile peritrichs by contrast microscopy. Fragments of infected tissues were subjected to histological processing and scanning electron microscopy. Epistylis sp. caused hemorrhagic ulcer disease, and cichlids were more prone to develop infestations throughout the body surface due to the attachment of the colonies to the scales, which did not occur with pimelodids. Multifocal granulomatous dermatitis was observed, associated with the hydropic degeneration... |
