| susceptibility of plasmodium falciparum in vitro to chloroquine, mefloquine, quinine and sulfadoxine/pyrimethamine in somalia: relationships between the responses to the different drugs. | the susceptibilities of plasmodium falciparum to chloroquine, mefloquine, quinine and sulfadoxine/pyrimethamine were investigated in mogadishu in 1988, after chloroquine resistance had spread widely in somalia. possible correlations of the responses to these drugs were also investigated. standard world health organization in vitro micro-tests were performed. of 76 isolates tested for chloroquine susceptibility, 58 (76%) were resistant to the drug with mean ec50 and ec99 values of 1.06 x 10(-6) m ... | 1991 | 1780976 |
