| development of a polymorphic strain of plasmodium vivax in monkeys. | a strain of plasmodium vivax from thailand with a polymorphic repeat unit of the circumsporozoite protein was established in saimiri sciureus boliviensis and 3 species of aotus monkeys. all 11 attempts to transmit infection via sporozoite inoculation, 4 times to splenectomized s. sciureus boliviensis, 2 times to splenectomized aotus nancymai, and 5 times to intact saimiri monkeys, were successful. anopheles freeborni, anopheles stephensi, anopheles dirus, and anopheles gambiae mosquitoes were in ... | 1992 | 1597793 |
| the uganda i/cdc strain of plasmodium malariae in aotus lemurinus griseimembra monkeys. | two lines of the uganda i/cdc strain of plasmodium malariae were studied in splenectomized aotus lemurinus griseimembra monkeys. a line initially adapted to these monkeys from an infected chimpanzee failed to produce high-level parasite counts or mosquito infection in 13 of this type of monkey during 16 linear passages. another line, originally adapted from the chimpanzee to aotus azarae boliviensis, after 7 linear passages in 3 different types of aotus was then passaged to 14 splenectomized a. ... | 1989 | 2645394 |
| transmission of the os strain of plasmodium inui to saimiri sciureus boliviensis and aotus azarae boliviensis monkeys by anopheles dirus mosquitoes. | eight saimiri and 7 aotus monkeys were exposed to infection with the os strain of plasmodium inui via the bites of from 2 to 7 anopheles dirus mosquitoes. all saimiri monkeys developed high-level infections of from 152,000 to 500,000/mm3 after prepatent periods of from 14 to 17 days. only 1 aotus monkey developed a patent infection after a period of 28 days. feeding on these animals failed to result in infection of an. dirus mosquitoes. | 1988 | 3379532 |
| infection of aotus azarae boliviensis monkeys with different strains of plasmodium falciparum. | eleven strains of plasmodium falciparum from asia, africa, and central america were inoculated into a total of 58 splenectomized aotus azarae boliviensis monkeys. eight of the strains produced high-level parasitemias, whereas 3 (2 from honduras and 1 from zaire) produced only low-level parasitemias. mosquito infections were only obtained during the first 2 linear passages of the santa lucia strain from el salvador. the results indicate that this species of aotus monkey is highly susceptible to i ... | 1986 | 3537256 |
| infection of aotus azarae boliviensis monkeys with different strains of plasmodium vivax. | sixty-seven splenectomized aotus azarae boliviensis were infected with strains of plasmodium vivax from southeast asia (2), new guinea (2), north korea (1), and central america (3). maximum parasitemias varied among the different strains, with the mean maximum parasitemia for the primary infection period being 16,200 per mm3. animals previously infected with plasmodium falciparum and plasmodium malariae produced maximum parasitemias of 30,200 and 11,900 per mm3, respectively. gametocytes infecti ... | 1985 | 3889264 |

| studies on the uganda i/cdc strain of plasmodium malariae in bolivian aotus monkeys and various anophelines. | a strain of plasmodium malariae (uganda i/cdc) was isolated from an infant who had been infected via blood transfusion from a donor who had entered the united states 8 yr previously. after passage through a splenectomized chimpanzee, the parasite was studied in 29 splenectomized aotus azarae boliviensis monkeys. maximum parasitemias were higher in aotus monkeys without previous plasmodium infection than in aotus monkeys with a history of p. vivax infection. animals with a history of infection wi ... | 1984 | 6392499 |
| studies on infections with the berok strain of plasmodium cynomolgi in monkeys and mosquitoes. | infections with the berok strain of plasmodium cynomolgi were induced in macaca mulatta, macaca fascicularis, macaca nemestrina, aotus lemurinus griseimembra, aotus azarae boliviensis, and saimiri boliviensis monkeys. transmission was obtained with sporozoites developing in anopheles peditaeniatus, anopheles maculatus, anopheles quadrimaculatus, anopheles culicifacies, and anopheles dirus mosquitoes. this strain of p. cynomolgi offers significant potential for a number of experimental studies. t ... | 1999 | 10219307 |
| adaptation of the amru-1 strain of plasmodium vivax to aotus and saimiri monkeys and to four species of anopheline mosquitoes. | a chloroquine-resistant strain of plasmodium vivax (amru-1) from papua new guinea has been adapted to grow in 4 species of aotus monkeys (aotus lemurinus griseimembra, aotus vaciferans, aotus nancymai, and aotus azarae boliviensis), hybrid aotus monkeys, and saimiri boliviensis monkeys. whereas it was possible to infect saimiri monkeys with this parasite by inoculation of parasitized erythrocytes, only 42% of saimiri monkeys became infected, compared to 92% of aotus monkeys attempted. comparativ ... | 1999 | 10461947 |
| coupling and decoupling of evolutionary mode between x- and y-chromosomal red-green opsin genes in owl monkeys. | we previously discovered y-chromosomal red-green opsin genes in two types of owl monkeys with different chromosomal characteristics. in one type, the y-linked opsin gene is a single-copy intact gene and in the other, the genes exist as multiple pseudogenes on a y/autosome fusion chromosome. in the present study, we first distinguished the two types of monkeys as distinct allopatric species on the basis of karyotypic characteristics: aotus lemurinus griseimembra (karyotype iii, diploid chromosome ... | 2005 | 15922519 |
| chronobiological background to cathemerality: circadian rhythms in eulemur fulvus albifrons (prosimii) and aotus azarai boliviensis (anthropoidea). | cathemeral activity, in which the animals' motor activity is almost evenly distributed throughout the dark and the light portion of the day, has been described in various lemur genera (eulemur, hapalemur) and in the owl monkey aotus azarai of the argentinean chaco. proximate and ultimate factors responsible for this behaviour are still being debated. however, the chronobiological background of the behaviour has largely been ignored. we studied e. fulvus albifrons and a. a. boliviensis under cont ... | 2006 | 16415579 |
| effects of habitat structure and fragmentation on diversity and abundance of primates in tropical deciduous forests in bolivia. | habitat structure and anthropogenic disturbance are known to affect primate diversity and abundance. however, researchers have focused on lowland rain forests, whereas endangered deciduous forests have been neglected. we aimed to investigate the relationships between primate diversity and abundance and habitat parameters in 10 deciduous forest fragments southeast of santa cruz, bolivia. we obtained primate data via line-transect surveys and visual and acoustic observations. in addition, we asses ... | 2010 | 20949116 |
| night monkey hybrids exhibit de novo genomic and karyotypic alterations: the first such case in primates. | using molecular chromosomal analyses, we discovered night monkey hybrids produced in captivity from matings between a female aotus azarae boliviensis (2n = 50) and a male a. lemurinus griseimembra (2n = 53). the parents produced seven offspring in total, including one male and six females - a pattern consistent with haldane's rule. chromosomal studies were conducted on four of the hybrid offspring. two of them showed relatively 'simple' mixture karyotypes, including different chromosome numbers ... | 2017 | 28369492 |
