| incidence of arbovirus isolated from mosquitoes in the forest region of south cameroun, region of yaoundé . | the authors give results of a survey of arboviruses isolated from mosquitoes in the neighborhood of yaoundé, southern cameroon, from 1964 to 1972. during this period of nine years 127.520 female mosquitoes including at least 72 species were collected and processed for attempt of virus isolation. 55 strains belonging to 12 viral types were recovered from at least 19 species of mosquitoes. the appearance of different viruses over the years was quite intermittent. a possible reason for this is the ... | 1976 | 16703 |
| origin and prevention of airport malaria in france. | since 1969, 63 cases of airport malaria have been reported in western europe, 24 of which occurred in france. most were due to plasmodium falciparum. in 1994, 7 cases occurred in and around roissy charles de gaulle airport (cdg), showing 4 types of contamination: among employees working on airstrips or opening containers, among residents living near the airport, among people living at some distance from the airport after a secondary transport of vectors, and by vectors transported in luggage. in ... | 1998 | 9754664 |
| high malaria transmission intensity in a village close to yaounde, the capital city of cameroon. | a 2-yr longitudinal malaria study was undertaken in a suburb of yaounde, the capital city of cameroon, in the village of simbock, approximately 2 km from the city limits. this study allowed assessment of malaria transmission intensity and dynamics in this region before implementation of pyrethroid impregnated bed nets through the national vector control program. anophelines were captured on human volunteers by pyrethrum spray collections and in resting sites outdoors. malaria vectors were anophe ... | 2002 | 11931035 |
| plasmodium falciparum transmission blocking immunity in three areas with perennial or seasonal endemicity and different levels of transmission. | plasmodium falciparum transmission blocking immunity (tbi) was investigated in 3 different endemic areas. reared anopheles gambiae s.s. were experimentally infected with the blood of gametocyte carriers, either in the presence of autologous plasma (own) or after replacement of the own plasma with a nonimmune serum of ab blood group (control). transmission reduction was defined by a lower level of mosquito infection in the own batch compared with the control. after controlling for the effect of g ... | 2005 | 16354818 |
