Arenales,Alexandre; Hoppe,Estevam G.L.; Gardiner,Chris; Mol,Juliana P.S.; Werther,Karin; Santos,Renato L.ABSTRACT: This study assessed microscopic morphology of protozoan and metazoan parasites, as well as parasite-associated histopathologic changes in five Brazilian free-ranging armadillos. Three armadillos had intra sarcolemmal cysts of Sarcocystis sp. in skeletal muscles without microscopic changes. One Dasypus novemcinctus was found parasitized with a nematode morphologically compatible with an oxyurid in the ...
Pathogenic potential of Brucella ovis field isolates with different genotypic p...
Carvalho,Thaynara P.; Ribeiro,Noelly Q.; Mol,Juliana P.S.; Costa,Fabíola B.; Eckstein,Camila; Paula,Nayara F.; Paixão,Tatiane A.; Santos,Renato L.ABSTRACT: Brucella ovis causes economic and reproductive losses in sheep herds. The goal of this study was to characterize infection with B. ovis field isolates in a murine model, and to evaluate protection induced by the candidate vaccine strain B. ovis ΔabcBA in mice challenged with these field isolates. B. ovis field strains were able to colonize and cause lesions in the liver and spleen of infected mice. Af...
