| [natural infection of triatoma vitticeps (stal, 1859) with flagellates morphologically similar to trypanosoma cruzi (chagas, 1909) in espírito santo state]. | adult specimens of triatoma vitticeps are frequently captured by residents in rural areas of the state of espírito santo, brazil. with aim of determining the natural infection rate of this species, we examined the excrement of 116 wild specimens, captured in 27 municipal districts of the state, after blood meal in chicken and spontaneous excretion. of these, 100 (86.2%) were infected with flagellates morphologically similar to trypanosoma cruzi. our results showed natural infection rates of trit ... | 2006 | 16501776 |
| the occurrence of an intraerythrocytic microorganism neitziella rezendei gen. nov. sp. nov. (microtatobiotes, rickettsiales) of poultry in brazil. | an extremely polymorphous intraerythrocytic microorganism occurring in naturally infected turkeys, ducks and fowls has been discovered in the states of minas gerais, rio de janeiro and espirito santo. 2. studies on the morphology and biology have shown that it is a hitherto undescribed heteroxenous parasite for which the name neitziella rezendei gen. nov., sp. nov. is proposed. 3. its morphological features permit its inclusion in the class microtatobiotes and order rickettsiales. 4. microscopic ... | 1976 | 13631 |
