the comparative susceptibility of anopheles quadrimaculatus and anopheles freeborni to infection by plasmodium vivax (st. elizabeth strain).		1950	14795201
development of different strains of plasmodium vivax in two species of anopheles.	anopheles freeborni mosquitoes with oocyst infections had salivary gland infections at a higher rate of plasmodium vivax from the new world than with strains from asia, particularly those from south vietnam. anopheles maculatus mosquitoes supported development from oocysts to heavily infected salivary glands for all the strains of p. vivax tested. the results suggest that p. vivax introduced from vietnam would be less likely to be transmitted by native a. freeborni mosiquitoes than would malaria ...	1976	779500
studies on human malaria in aotus monkey. vii. comparative infectivity of two strains of plasmodium vivax to to anopheles freeborni, a. maculatus, and for strains of a. albimanus.	a strain of plasmodium vivax from el salvador was shown to be more infectious to the apastepeque strain of anopheles albimanus from el salvador than was a strain of p. vivax from colombia, s. a. the apastepeque mosquito strain was also more susceptible to the savadoran strain of p. vivax than were 2 other strains of this mosquito from el salvador. a strain of a. albimanus from panama was more susceptible to both of the parasite than were any of the salvadoran strains of a. albimanus.	1976	817008
an outbreak of introduced malaria in california possibly involving secondary transmission.	during 1974, 12 cases of plasmodium vivax malaria were reported from an agricultural area in california's sacramento valley. at least three of these cases resulted from local mosquito transmission. the imported cases were in punjabi immigrants except for one in an american-born visitor to the punjab. this is the 11th reported outbreak of introduced malaria in the united states since 1952, and the first in california since 1957. a unique aspect of this outbreak is the likelihood that secondary tr ...	1977	320891
the chesson strain of plasmodium vivax in aotus monkeys and anopheline mosquitoes.	the chesson strain of plasmodium vivax was studied in aotus trivirgatus monkeys. parasitemia in intact and splenectomized animals was similar to that reported for this strain in man. comparative infectivity studies with mosquitoes fed on infected monkeys indicated that the most susceptible was anopheles freeborni, followed by an. balabacensis, an. culicifacies, an. maculatus, an. atroparvus, an. stephensi, an. quadrimaculatus, and an. albimanus. transmissions via sporozoites from an. maculatus w ...	1980	6771379
studies on the west pakistan strain of plasmodium vivax in aotus monkeys and anopheline mosquitoes.	the west pakistan strain of plasmodium vivax was established in 17 aotus trivirgatus griseimembra monkeys. parasitemias were moderate. prior experience of the animals with p. falciparum and a heterologous strain of p. vivax resulted in a marked reduction in parasitemias, but maintenance of mosquito infectivity similar to that of animals with no prior malaria. comparative infectivity studies indicated that this strain in aotus monkeys was most infective to anopheles freeborni mosquitoes followed ...	1980	7007600
studies of the sal i strain of plasmodium vivax in the squirrel monkey (saimiri sciureus).	the sal i strain of plasmodium vivax was successfully adapted to three phenotypes of the squirrel monkey, saimiri sciureus. through five linear blood passages, parasitemias in excess of 200,000/mm3 blood were attained; bolivian phenotype saimiri appear to develop higher peak parasitemias. sporozoites of the sal i strain inoculated intravenously produced patent parasitemias in all five squirrel monkeys challenged, with prepatent periods ranging from 21 to 38 days. anopheles freeborni and an. gamb ...	1983	6355425
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
infectivity of two strains of plasmodium vivax to anopheles albitarsis mosquitoes from colombia.	anopheles albitarsis obtained from villavicencio, colombia, were colonized in the laboratory using force-mating techniques. laboratory reared mosquitoes were allowed to feed on aotus monkeys infected with the salvador ii or the rio meta strains of plasmodium vivax from el salvador and colombia, respectively. in comparison with other species, the an. albitarsis were less susceptible than anopheles freeborni, anopheles culicifacies and strains of anopheles albimanus from el salvador, panama and co ...	1985	3912483
studies of comparative infectivity of fifteen strains of plasmodium vivax to laboratory-reared anopheline mosquitoes, with special reference to anopheles culicifacies.	the sattoki strain of species a of the taxon anopheles culicifacies giles was infected with 15 different strains of plasmodium vivax from asia, new guinea, and central and south america. a comparison of the relative infectivity indicated a marked variation for the different strains of p. vivax when compared to anopheles freeborni mosquitoes.	1986	3537255
chesson strain plasmodium vivax in saimiri sciureus boliviensis monkeys.	nine saimiri sciureus boliviensis monkeys were inoculated with sporozoites of plasmodium vivax (chesson strain) dissected from anopheles stephensi mosquitoes infected by feeding on blood from infected chimpanzees. the animals were splenectomized 7 days after inoculation. seven animals developed infections with prepatent periods ranging from 12 to 43 days (mean of 19.6 days). parasitemias were low during the first 50 days. maximum parasitemias in 5 animals in which the strain adapted ranged from ...	1987	3309241
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
further studies on the sporozoite transmission of the salvador i strain of plasmodium vivax.	different species of saimiri and aotus monkeys were inoculated with sporozoites of the salvador i strain of plasmodium vivax. of 58 saimiri inoculated, 45 developed parasitemia (4 following bites and 41 following intravenous inoculation). prepatent periods ranged from 10 to 63 days. twelve of 19 monkeys inoculated with sporozoites that had been stored frozen developed patent parasitemia after 16-53 days. of 41 aotus monkeys inoculated, only 10 (2 via bites and 8 via intravenous inoculation) deve ...	1994	8064516
plasmodium vivax infections in chimpanzees for sporozoite challenge studies in monkeys.	the development and testing of vaccines directed against plasmodium vivax has relied on saimiri and aotus monkeys as the animal test system and on chimpanzees to provide infective gametocytes to produce sporozoites for monkey challenge studies and vaccine development. one sporozoite-induced and 29 blood-induced infections with the salvador i strain of p. vivax were studied in splenectomized chimpanzees. eighteen primary infections with p. vivax resulted in maximum parasite counts ranging from 1, ...	1996	8842127
studies on a primaquine-tolerant strain of plasmodium vivax from brazil in aotus and saimiri monkeys.	a nonimmune american acquired an infection of plasmodium vivax type 1 malaria in brazil in 1994. after returning to the u.s.a., he had a primary attack followed by 3 relapses. the primary attack and first 2 relapses were treated with a standard regimen of chloroquine, followed by 14 days of primaquine (15 mg/day). following the third relapse, the primaquine treatment was extended to 28 days. no further relapses occurred. the lack of response to primaquine by this strain may recommend it as a sui ...	1997	9267419
adaptation of a strain of plasmodium vivax from mauritania to new world monkeys and anopheline mosquitoes.	a strain of plasmodium vivax from mauritania was adapted to develop in aotus lemurinus griseimembra, aotus nancymai, saimiri boliviensis, and hybrid aotus monkeys. infections were induced via the inoculation of sporozoites dissected from the salivary glands of anopheles gambiae, anopheles freeborni, and anopheles stephensi mosquitoes or the intravenous passage of infected erythrocytes. infections in 3 a. lemurinus griseimembra monkeys readily infected mosquitoes. four lines of the mauritania par ...	1998	9645868
salvador ii strain of plasmodium vivax in aotus monkeys and mosquitoes for transmission-blocking vaccine trials.	infections with the salvador ii strain of plasmodium vivax in aotus lemurinus griseimambra monkeys were fed upon by anopheles freeborni mosquitoes. periods of mosquito infectivity were determined to establish a model system for the testing of transmission-blocking vaccines. the highest levels of mosquito infection were associated with the ascending asexual parasitemia after reaching 1,000/microl, and before the peak asexual parasite count. sporozoite-induced infections were more infectious than ...	1998	9684622
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
potential of the panama strain of plasmodium vivax for the testing of malarial vaccines in aotus nancymai monkeys.	aotus monkeys were infected with a strain of plasmodium vivax from panama to determine its potential for the testing of malarial vaccines. after sporozoite inoculation, 3 splenectomized aotus nancymai that had been infected previously with plasmodium falciparum and p. vivax had prepatent periods of 13, 15, and 15 days with maximum parasite counts of 12,726/microl, 5,310/microl, and 9,180/microl. three other a. nancymai previously infected with p. falciparum only had prepatent periods of 17, 15, ...	2002	12479543
