isoenzyme characterization of trypanosoma evansi isolated from capybaras and dogs in brazil.trypanosoma evansi was seen in blood samples taken randomly from both wild and semi-captive capybaras caught in mato grosso do sul state, brazil and in sick dogs brought into local veterinary clinics. trypanosome stocks from capybaras and dogs were significantly different in their patterns of growth in mice, while the trypanosomes from dogs were mostly dyskinetoplastic. by isoenzyme electrophoresis all the trypanosomes were of the most common type of t. evansi found elsewhere.19892571248

[seasonal evaluation of mammal species richness and abundance in the "mário viana" municipal reserve, mato grosso, brasil].we evaluated seasonal species presence and richness, and abundance of medium and large sized mammalian terrestrial fauna in the "mário viana" municipal biological reserve, nova xavantina, mato grosso, brazil. during 2001, two monthly visits were made to an established transect, 2,820 m in length. records of 22 mammal species were obtained and individual footprint sequences quantified for seasonal calculation of species richness and relative abundance index (x footprints/km traveled). all 22 spec ...200618491629
