Provedor de dados: 45
Autores: Breves,P.; Porto,M.; Pissinatti,A.; Luz,D.; Menezes,R.C.
The results of a study on nematode fauna occurring in wild iguanas (Iguana iguana) from Brazilian Northeast (Alagoas and Maranhão) and Central-west (Goiás and Mato Grosso) areas were presented. Six adult iguanas, three males and three females, were necropsied and the digestive system removed to examination. All the iguana specimens were heavily parasitized. The helminths diagnosed were: Ozolaimus cirratus in the cecum and colon of five iguanas; Ozolaimus megatyphlon in cecum, colon and rectum of three iguanas; and Alaeuris vogelsangi in the small intestine, cecum, colon and rectum of five animals. Two larvae of Ozolaimus sp. were recovered from the pyloric region of the stomach of one iguana. The three diagnosed species of nematodes were reported for the...

Provedor de dados: 45
Autores: Trotte,M.N.S.; Santos,B.F.; Menezes,R.C.; Tortelly,R.
Verificaram-se a prevalência e as características anatomopatológicas de neoplasias espontâneas encontradas em camundongos, provenientes de biotério. Foram necropsiados 9.219 camundongos pertencentes a 13 linhagens, entre agosto de 2002 e janeiro de 2007, para monitoramento sanitário. Amostras de tecidos foram colhidas, fixadas em formol tamponado a 10% e processadas pelas técnicas habituais para inclusão em parafina. Foram realizados 84 diagnósticos de neoplasmas, sendo acometidos 82 camundongos (0,9%). As principais neoplasias diagnosticadas com as respectivas ocorrências foram: carcinoma mamário, 27,4%; linfoma, 19,0%; adenocarcinoma papilífero pulmonar primário, 17,9%; carcinoma epidermoide, 8,3%; osteossarcoma osteoblástico, 4,8%; e outros com menor...

Systematic and pathologic study of Paratanaisia bragai (Santos, 1934) Freitas, 1959 (Digenea, Eucotylidae) infestation in ruddy ground dove Columbina talpacoti (Temminck, 1811)
Provedor de dados: 45
Autores: Pinto,R.M.; Menezes,R.C.; Tortelly,R.
This is the first report of the digenetic trematode Paratanaisia bragai infestation in a ruddy ground dove Columbina talpacoti, captured in a suburban area of Rio de Janeiro, Brazil. Although with a low prevalence (10%), the intensity of infection was high, considering that 116 worms were recovered from one of the kidneys. Gross lesions were not observed and histopathological analysis showed very dilated renal collecting ducts with destruction and flattening of the lining epithelial cells, without inflammatory reaction. The pathological findings were compared to those previously reported for P. bragai in other hosts, since the proposal of the species in 1934.

Avaliação da confiabilidade entre dois observadores em exames citopatológico e imunocitoquímico de aspirado de medula óssea no diagnóstico da leishmaniose visceral canina
Provedor de dados: 45

ABSTRACT Visceral leishmaniasis is a zoonosis in which the dog appears as the main source of infection in urban areas. Its diagnosis is complex and the cytopathological exam is a fast and cheap alternative to parasite direct visualization and its sensitivity can be increased by immunocytochemistry, though with a higher cost. The accuracy of such methods is dependent on the microscopist's experience and therefore, this study evaluated the reliability of such techniques between two observers, from bone marrow aspirates of 50 dogs from an endemic area for the disease. The parasitological culture in Novy-MacNeal-Nicolle medium was used as the reference standard. Among the main findings, the sensitivities obtained by observers I and II were respectively 62.5%...

An anatomopathological study of hepatic coccidiosis (Calyptospora sp.) in the Acará-pixuna, Aequidens plagiozonatus Kullander, 1984 from the Brazilian state of Pará
Provedor de dados: 45
Autores: Videira,M.; Velasco,M.; Tortelly,R.; Menezes,R.C.; São Clemente,S.C.; Matos,E.
The present study focuses on the anatomopathological alterations provoked by parasitism by Calyptospora sp. in 40 specimens of Aequidens plagiozonatus collected in Pará, Brazil. Examinations of the fresh material by compression of the hepatopancreas and histological sections showed immature forms and oocysts characteristic of the genus Calyptospora, in addition to a large quantity of melanomacrophagic centers spread throughout the organ. No significant inflammation of the hepatic tissue was observed. The melanomacrophagic centers and the compression of the hepatocytes are part of the response of the host to the parasite. This study represents the first record of parasitism by Calyptospora in A. plagiozonatus.

Prevalência da infecção por Toxoplasma gondii em galinhas criadas extensivamente em Rio Bonito, Rio de Janeiro
Provedor de dados: 45
Autores: Casartelli-Alves,L.; Ferreira,L.C.; Vicente,R.T.; Millar,P.R.; Oliveira,R.V.C.; Amendoeira,M.R.R.; Schubach,T.M.P.; Menezes,R.C.
The prevalence of T. gondii infection was investigated in free-range chickens for human consumption in the county of Rio Bonito, Rio de Janeiro, Brazil. Thus, a search for antibodies to T. gondii by indirect fluorescent antibody test was done in the serum of 220 chickens from twenty two farms. Titres equal or greater than 16 were considered positive. The prevalence of toxoplasmic infection found in chickens was 27.6% (61/220). There were positive cases in eighteen (77.2%) farms. The more frequent titre was 16 (12.5%) and the highest was 4096 (0.4%). The high prevalence of T. gondii in chickens and the high percentage of farms with positive cases indicate environmental contamination in the studied area showing the possibility of human and animal infection.

Provedor de dados: 45
Autores: Mattos Jr.,D.G.; Pinheiro,J.M.; Menezes,R.C.; Costa,D.A.
Leihsmaniasis is a protozoal disease transmitted by dipteran insects. The dog is an important domestic host of both visceral and cutaneous forms of the disease. These forms affects humans in many countries, and it is considered a serious risk for human health. This study reports clinical and laboratorial data from 18 dogs. Nine dogs were positive by indirect immunofluorescence technique and the other nine were negative. The dogs were clinically monitored for 30 days and laboratorial changes were assessed. Three blood samples were collected for hemogram and serum biochemistry at 0, 15, and 30 days. The clinical signs of positive dogs were compatible with the disease, including lymphadenopathy, cutaneous ulcers, hyperthermia, apathy, cachexia and ulcerated...
