| identification of endotrypanum species from a sloth, a squirrel and lutzomyia sandflies in ecuador by pcr amplification and sequencing of the mini-exon gene. | pcr amplification and nucleotide sequencing of the mini-exon gene revealed that four strains isolated from a sloth (choloepus hoffmanni), a squirrel (sciurus granatensis) and two sandflies (lutzomyia hartmanni) in ecuador were indistinguishable from endotrypanum monterogeii. another strain isolated from lu. hartmanni showed the high sequence similarity to e. schaudinni. since three of these strains have been previously identified as leishmania (viannia) equatorensis, the results demonstrate that ... | 2003 | 12808222 |
| multiple detection of zoonotic variegated squirrel bornavirus 1 rna in different squirrel species suggests a possible unknown origin for the virus. | the recently discovered variegated squirrel bornavirus 1 (vsbv-1) caused the death of three squirrel breeders in germany. subsequent first screening of squirrels with in vivo collected swab samples and a vsbv-1-specific rt-qpcr revealed not only variegated squirrel infections (sciurus variegatoides), but also prevost's squirrels (callosciurus prevostii) as positive for vsbv-1 genome. in this study, 328 squirrels were tested using the established rt-qpcr assays. in 16 individual animals vsbv-1 rn ... | 2017 | 28593419 |
| molecular diagnosis of trypanosoma cruzi/leishmania spp. coinfection in domestic, peridomestic and wild mammals of venezuelan co-endemic areas. | american trypanosomiasis and leishmaniases are diseases caused by protozoans of the trypanosomatidae family. in venezuela, although several endemic foci of both diseases coincide, there are no reports of coinfection in mammals. the molecular diagnosis of the coinfection t. cruzi-leishmania spp. was done in 527 blood samples collected on filter paper of several species of mammals (canis familiaris, equus asinus, didelphis marsupialis, equus mulus, rattus rattus, equus caballus, artibeus fratercul ... | 2018 | 31014717 |
| post-dispersal predation and scatterhoarding of dipteryx panamensis (papilionaceae) seeds by rodents in panama. | in tropical rain forests of central america, the canopy tree dipteryx panamensis (papilionaceae) fruits when overall fruit biomass is low for mammals. flying and arboreal consumers feed on d. panamensis and drop seeds under the parent or disperse them farther away. seeds on the ground attract many vertebrate seed-eaters, some of them potential secondary seed dispersers. the fate of seeds artificially distributed to simulate bat dispersal was studied in relation to fruitfall periodicity and the v ... | 1993 | 28314040 |
| [frugivory and seed dispersal oenocarpus bataua palm (arecaceae) in a forest from the colombian andes]. | seed dispersal is a key process that determines the spatial structure and dynamics of populations of plants, establishes the potential area of recruitment and in this way, the basis for subsequent processes such as predation, germination, competition and growth. the purpose of this research was to identify the guild of frugivores of the oenocapus bataua palm in fragments of andean forest, determine the effective dispersers and relate the spatial distribution of palm populations with the dispersi ... | 2012 | 23342501 |
| feeding success of lutzomyia evansi (diptera: psychodidae) experimentally exposed to small mammal hosts in an endemic focus of leishmania chagasi in northern colombia. | lutzomyia evansi is the vector of leishmania chagasi in northern colombia. differences in feeding success were revealed, when this phlebotomine sand fly was fed on five species of small mammal hosts from an endemic focus of visceral leishmaniasis. in each trial, 50 female sand flies were provided access to similar-sized depilated areas of the hind foot of each of 44 individual mammals and allowed to feed for 30 minutes. the number of engorged sand flies was counted at the end of each trial and c ... | 2003 | 14968917 |
| dynamics of leishmania chagasi infection in small mammals of the undisturbed and degraded tropical dry forests of northern colombia. | the infection rate with leishmania chagasi and the population dynamics of small mammals were studied in an undisturbed forest reserve (colosó) and an area of highly degraded forest (san andrés de sotavento [sas]) in northern colombia, both endemic for visceral leishmaniasis. live trapping of mammals was done every month, and species, age, sex and reproductive status determined. l. chagasi was detected in samples of skin or spleen by the polymerase chain reaction, after extraction of deoxyribonuc ... | 1998 | 9861395 |
| ecological distinctions between sympatric species of saguinus and sciurus. | tamarins are small new world monkeys that have been described as "squirrellike." squirrels, along with bats and birds, are the taxa most likely to utilize resources similar to those used by primates in the tropical forest canopy. in this paper we compare differences in ecology, diet, locomotion, and habitat utilization between sympatric populations of tamarins (saguinus oedipus) and tree squirrels (sciurus granatensis) in panama. data presented indicate that although there is some degree of reso ... | 1984 | 6439048 |
| description of leishmania equatorensis sp. n (kinetoplastida: trypanosomatidae), a new parasite infecting arboreal mammals in ecuador. | characterization is given of a new parasite, leishmania equatorensis sp. n., which was isolated from the viscera of a sloth (choloepus hoffmanni) and a squirrel (sciurus granatensis), captured in humid tropical forest on the pacific coast of ecuador. data based on biological and molecular criteria, as well as numerical zymotaxonomical analysis, indicate that this parasite is a new species of the l. braziliensis complex. l. equatorensis is clearly distinguishable from all other known species with ... | 1992 | 1308568 |
| molecular characterization of trypanosoma cruzi and leishmania spp. coinfection in mammals of venezuelan coendemic areas. | trypanosoma cruzi and leishmania spp. are protozoans that cause american trypanosomiasis and leishmaniasis, respectively. in endemic foci where both diseases coincide, coinfection can occur. the objective of this work was the characterization of the parasites involved in coinfection in several endemic areas of venezuela. | 2020 | 32655075 |
