| leishmania herreri sp. n. from sloths and sandflies of costa rica. | leishmania herreri sp. n. is described after isolation in pure culture from blood, viscera and skin of two-toed (choloepus hoffmanni) and three-toed (bradypus griseus) sloths from costa rica. also, it was isolated from the following sandflies: lutzomyia trapidoi, l. ylephiletor and l. shannoni. the amastigote forms were not seen in the final hosts but they were obtained in tissue culture at 33 c. both promastigotes and amastigotes failed to infect hamsters. the new parasite is isolated frequentl ... | 1979 | 448612 |
| leishmania herreri (kinetoplastida; trypanosomatidae) is more closely related to endotrypanum (kinetoplastida; trypanosomatidae) than to leishmania. | | 1996 | 8885228 |
| evolution of the genus leishmania revealed by comparison of dna and rna polymerase gene sequences. | previous hypotheses of leishmania evolution are undermined by limitations in the phylogenetic reconstruction method employed or due to the omission of key parasites. in this experiment, sequences of the gene encoding the dna polymerase alpha catalytic polypeptide (pola) were analysed phylogenetically in combination with those encoding the rna polymerase ii largest subunit gene (rpoiils) to infer a comprehensive phylogeny of leishmania. nineteen species of parasites were studied, comprising repre ... | 1997 | 9364962 |
