Genetic polymorphism and molecular epidemiology of Leishmania (Viannia) brazili...
Cupolillo, Elisa; Brahim, Lúcia Regina; Toaldo, Cristiane Bentin; Paes de Oliveira-Neto, Manoel; Brito, Maria Edileuza Felinto de; Falqueto, Aloi?ioNumerical zymotaxonomy and variability of the internal transcribed spacers (ITS) between the small and large subunits of the rRNA genes were used to examine strain variation and relationships in natural populations of Leishmania (Viannia) braziliensis. A total of 101 strains from distinct hosts and Brazilian geographic regions were assigned to 15 zymodemes clustered in two major genetic groups. The great number...
Characterization of Endotrypanum Parasites Using Specific Monoclonal Antibodies
Franco, A. M.; MacHado, Gérzia Maria de Carvalho; Naiff, Roberto Daibes; Moreira, Celia F.S.; McMahon-Pratt, Diane; Grimaldi Júnior, Gabriel F.A large number of Endotrypanum stocks (representing an heterogeneous population of strains) have been screened against a panel of monoclonal antibodies (MAbs) derived for selected species of Endotrypanum or Leishmania, to see whether this approach could be used to group/differentiate further among these parasites. Using different immunological assay systems, MAbs considered specific for the genus Endotrypanum (...
Epidemiological and nosological aspects of Leishmania naiffi Lainson & Shaw, 1989.
Naiff, Roberto Daibes; Freitas, Rui Alves de; Naiff, Maricleide de Farias; Arias, Jorge Ramon; Barrett, Toby Vincent; Momen, HoomanLeishmania naiffi was isolated from 10 out of 64 armadillos (Dasypus novemcinctus) examined in Amazonas, Pará and Rondônia States in the Brazilian Amazon Region. The isolates were obtained in culture from samples of liver (3), spleen (3), lymph nodes (2), skin (1) and blood (1) from the infected animals. Heavy infections with the same parasite were detected for the first time in Psychodopygus squamiventris, a c...
