| biological behaviour in mice of trypanosoma cruzi isolates from amazonas and paraná, brazil. | the biological behaviour of 23 trypanosoma cruzi isolates in swiss mice was compared. nineteen isolates were obtained from patients in the acute phase of chagas disease (13), sylvatic reservoir hosts (didelphis marsupialis) (3), and triatomine bugs (rhodnius robustus) (3) from four regions of the state of amazonas (am). four isolates were obtained from chronic chagasic patients in the state of paraná (pr): three autochthones, and one allochthone from the state of minas gerais. only one isolate w ... | 2012 | 22406038 |
| didelphis marsupialis (common opossum): a potential reservoir host for zoonotic leishmaniasis in the metropolitan region of belo horizonte (minas gerais, brazil). | identification of the zoonotic reservoir is important for leishmaniasis control program. a number of (wild) animal species may serve as reservoir hosts, including the opossum didelphis marsupialis. a survey carried out in didelphis specimens (n = 111) from the metropolitan region of belo horizonte, an important focus of human leishmaniasis in brazil, is reported. all animals were serologically tested with indirect fluorescence antibody test (ifat) and direct agglutination tests (dat) based on l. ... | 2007 | 17767408 |
| life cycle of ixodes (ixodes) loricatus (acari: ixodidae) under laboratory conditions. | the life cycle of ixodes (ixodes) loricatus neumann, reared in the laboratory, is described. engorged females collected from opossums trapped in the states of minas gerais and são paulo, brazil, which were used to start the laboratory colonies, were designated as bmg and csp, respectively. larval and nymphal ticks from both colonies fed separately on rattus norvergicus berkenhout or calomys callosus rengger, whereas didelphis marsupialis l and didelphis albiventris lund were used as hosts for bm ... | 2000 | 11004783 |
