| development of plasmodium inui in the aotus trivirgatus monkey. | four splenectomized aotus trivirgatus griseimembra monkeys were affected with the os strain of plasmodium inui, a parasite of old world macaques. high parasite densities were obtained and two of the animals died. surviving animals maintained low to moderate level of chronic infections. three of the four animals produced parasitemias which infected anopheles dirus mosquitoes; oocyst densities were very low, however. | 1981 | 7241282 |
| forest malaria in bangladesh. iii. breeding habits of anopheles dirus. | a thorough, repetitive, 21-month search for breeding sites of anopheles dirus (=an. balabacensis s.l.) was conducted within a 3-km radius of an isolated, holoendemic malaria focus. during the annual 6-month monsoon, all breeding within 1.5 km of the focus took place at eight sites in 1975 and at nine sites in 1976. these sites were of two topographic types--puddles on footpaths and turbulence pits at the heads of drainage gullies--that shared the characteristic of being able to hold water for at ... | 1982 | 7072884 |
| forest malaria in bangladesh. ii. transmission by anopheles dirus. | seasonal, holoendemic malaria transmission in a small, isolated forest community was studied by doing outdoor and indoor all-night man-biting catches over 21 consecutive months. more than 3.8% of anopheles dirus (=an. balabacensis s.l.), the most frequently caught anopheline, were infective. one an. annularis was also infective. transmission occurred only during the 7-month monsoon. in the absence of ddt, an. dirus bit with equal frequency indoors and outdoors. when ddt was present in dwellings, ... | 1982 | 7072883 |
| sporozoite-induced plasmodium cynomolgi infections in captive born macaca fascicularis. | capability of captive born cynomolgus monkeys to substitute for rhesus in the plasmodium cynomolgi radical curative antimalarial drug development model was examined. eighteen monkeys divided into 3 groups were given standard or high doses of sporozoites intravenously. one group of 4 received 0.8 - 1.6 x 10(6) and a second group of 8 received 0.3 - 1.0 x 10(7) sporozoites. the third group of 6 was splenectomized and then received 3.0 - 4.0 x 10(6). the 2 groups of intact monkeys developed a persi ... | 1984 | 6740373 |
| esterase patterns of anopheles dirus (bangkok strain) and anopheles balabacensis (perlis form) in the laboratory. | esterase isoenzyme were performed in anopheles balabacensis (perlis form) and anopheles dirus (bangkok strain and kanchanaburi strain). the zymogram showed four positions, e1, e2, e3 and e4. seventy-five percent of an. balabacensis (perlis form) or an. dirus (bangkok strain) can be correctly diagnosed by the presence of fast band in e3 or super slow band in e3 respectively. homozygous slow band of e3 cannot be fully distinguished in both species, but by the combination of e2 and e3, 99.42% can b ... | 1983 | 6612417 |
| cytogenetic studies of some species complexes of anopheles in thailand and southeast asia. | recent studies on cytogenetics, behavioral, geographical and distinct morphological characters on adult, pupal and larval stages have revealed that "balabacensis" is a species complex. anopheles dirus the mainland species, is distributed widely in thailand and is renowned for its role as primary vector of human malarial parasites. further, evidence from cytogenetic and taxonomic studies suggests that "an. dirus" is a species complex comprising at least four distinct species provisionally designa ... | 1984 | 6543543 |
| infection and transmission studies with the n-3 strain of plasmodium fieldi in the macaca mulatta monkey. | seven different anophelines--anopheles freeborni, an. dirus, an. maculatus, an. atroparvus, an. stephensi, an. albimanus, and an. quadrimaculatus--were shown to be susceptible to infection with the n-3 strain of plasmodium fieldi. transmission was obtained via the bites of an. dirus, an. stephensi, and an. maculatus mosquitoes to macaca mulatta monkeys. sporozoites dissected from an. freeborni were also shown to be infectious. anopheles dirus and an. stephensi were the most suitable mosquitoes f ... | 1984 | 6491849 |
| plasmodium falciparum infection in bisazir chemosterilized anopheles dirus in laboratory studies. | bisazir, at a 0.5% solution induced sterility in males and at a 1.5% solution in female a. dirus. these sterilizing doses reduced p. falciparum infection in mosquitoes, however, they can still transmit malaria. it is concluded that by the concentration of 1.5 and 2.0% that induced complete sterility in males and females are not safe in sterile-male release programme for the control of a. dirus, unless all females were eliminated prior to release. | 1984 | 6390705 |
