Domestic dog (Canis domesticus) and the coyote (Canis latrans) are the only known definitive hosts for the protozoan Neospora caninum that causes abortion in dairy cattle. In the present study, antibodies to N. caninum were sought in three species of wild canids, Cerdocyon thous, Lycalopex gymnocercus and Dusicyon vetulus from Brazil. Antibodies to N.(More)
This study employed manipulation of sensory inputs (vision and plantar-surface cutaneous sensation) during gait termination to elicit insight into the roles played by these sensory systems in the control of gait termination. Attenuation of cutaneous sensation was achieved through hypothermic anesthesia. Visual information was occluded using special glasses.(More)
The development of consistent procedures with the inclusion of patient-specific data is essential in the computational modeling of biological processes, in order to achieve clinical relevant data. In this work, these issues are addressed with the development of a methodology that combines the gold standard technique for bone mineral density measurement and(More)
Oral manifestations often found in HIV-infected children are frequently the first clinical sign of the infection. This article aims to report the prevalence of oral manifestations in soft tissues and their relationship with the degree of immunosuppression in 80 HIV-infected patients (average age 6.30 +/- 3.32 years old) at the IPPMG-UFRJ. Thirty children(More)
The prevalence of anti-Toxoplasma gondii antibodies was evaluated by the indirect immunofluorescent-antibody test in serum of 57 wild canids from three different species: Lycalopex gymnocercus, Cerdocyon thous and Dusicyon vetulus from the northeast, southeast and southern regions of Brazil. The prevalence was 35.1%, with 20 of the 57 canids demonstrating(More)
Although antibodies to Bartonella henselae have been described in all neotropical felid species, DNA has been detected in only one species, Leopardus wiedii. The aim of this study was to determine whether DNA of Bartonella spp. could be detected in blood of other captive neotropical felids and evaluate risk factors and hematological findings associated with(More)
Glycine max soybean and its derivates stand out as functional food due to its content being free of aglycon isoflavones and their respective beta-glucosides. This study is aimed at classifying and quantifying the isoflavones content in defatted soy flour (DSF) derivates and textured soy protein (TSP). From DSF and TSP samples found in the market, the soy(More)
Mycoplasma suis is a hemotropic bacteria of red blood cells and the causative agent of swine eperythrozoonosis. Diagnosis of infection may be reached by direct examination of blood smears; however, the use of polymerase chain reaction (PCR) of the 16S RNA gene of M. suis improves the sensitivity and specificity of detection. The aim of this study was to(More)
This study aimed to assess the influence of incubation conditions in the determination of bacterial production (BP). In order to achieve that goal, experimental setups were performed in situ and in the laboratory under both dark and light conditions. To test spatial and seasonal variations and the different natural light exposure of microorganisms, sampling(More)
Purpose: Lympboprolifcrativc ocular adnexal lesions represent 1 spectrum of disorders which range from reactive lymphoid hyperplasia to malignant lymphoma and include lewas which ared an mddcrminatc nature morphologrccally and immunophenotypically. Futhmnwe cases have been ckcvmented where progresswn from reactix hyperplasia to frank Ippboma has camed. We(More)
