| simian malaria in brazil. | in brazil simian malaria is widely spread, being frequent in the amazon region (10% of primates infected) and even more in the forested coastal mountains of the southeastern and southern regions (35% and 18% infected, respectively), but absent in the semi-arid northeast. only two species of plasmodia have been found: the quartan-like plasmodium brasilianum and the tertian-like p. simium, but the possible presence of other species is not excluded. p. brasilianum is found in all enzootic foci, but ... | 1992 | 1343676 |
| sero-epidemiological studies of malaria in indian tribes and monkeys of the amazon basin of brazil. | a sero-epidemiological study of malaria, with special emphasis on plasmodium brasilianum/p. malariae, was conducted on 4 indian tribes living in the amazon basin of northern brazil: the arara, the parakana, the asurini, and the metuktire. the incidence of malaria, as determined by blood films, was very low in all tribes. parasitemia levels in most individuals were less than 0.02%; determination of the plasmodial species was not feasible. high levels of antibodies to both blood stages and sporozo ... | 1989 | 2508499 |

| simian malaria at two sites in the brazilian amazon. i--the infection rates of plasmodium brasilianum in non-human primates. | the parasite that causes simian malaria in the brazilian amazon, plasmodium brasilianum, is infective to man. in this region, where humans live within and in close proximity to the forest, it was suspected that this parasite could be the cause of a zoonosis. a study was performed in the areas surrounding two hydroelectric plants in the amazon, balbina and samuel, aiming at determining the zoonotic potential of this parasite. p. brasilianum was detected in, respectively, 15.8% and 9.9% of 126 and ... | 1995 | 8544737 |
| simian malaria at two sites in the brazilian amazon--ii. vertical distribution and frequency of anopheline species inside and outside the forest. | an anopheline survey was carried out in two simian malaria areas in the brazilian amazon, balbina and samuel, to determine the potential vectors of plasmodium brasilianum. the most abundant and/or acrodendrophilic anophelines in the forest and the most likely vector were anopheles mediopunctatus, an. nuneztovari, an. oswaldoi, an. triannulatus and an. shannoni. an. darlingi and an. marajoara were captured essentially in anthropic habitats outside the forest and are unlikely to be involved in the ... | 1996 | 9283645 |
| natural plasmodium infection in monkeys in the state of rondônia (brazilian western amazon). | simian malaria is still an open question concerning the species of plasmodium parasites and species of new world monkeys susceptible to the parasites. in addition, the lingering question as to whether these animals are reservoirs for human malaria might become important especially in a scenario of eradication of the disease. to aid in the answers to these questions, monkeys were surveyed for malaria parasite natural infection in the amazonian state of rondônia, brazil, a state with intense envir ... | 2013 | 23731624 |
| the genetic diversity of plasmodium malariae and plasmodium brasilianum from human, simian and mosquito hosts in brazil. | plasmodium malariae is a protozoan parasite that causes malaria in humans and is genetically indistinguishable from plasmodium brasilianum, a parasite infecting new world monkeys in central and south america. p. malariae has a wide and patchy global distribution in tropical and subtropical regions, being found in south america, asia, and africa. however, little is known regarding the genetics of these parasites and the similarity between them could be because until now there are only a very few ... | 2012 | 22705349 |
