Treatment of falciparum malaria with quinne and tetracycline or combined mefloquine/sulfadoxine/pyrimethamine on the Thai-Kampuchean border.

Three different regimens were compared for treatment of falciparum malaria in displaced Kampucheans living in encampments on the Thai-Kampuchean border in 1983: single dose 750 mg mefloquine, 1.5 g sulfadoxine, 75 mg pyrimethamine (MSP); 600 mg quinine 8-hourly for 3 days and 500 mg tetracycline 8-hourly for 7 days (Q3T7); or 600 mg quinine 8-hourly for 7 days and 500 mg tetracycline 8-hourly for 7 days (Q7T7). Radical cure rates were 98% (40/41) for MSP, 76% (32/42) for Q3T7 and 92% (33/36) for Q7T7.

Occurrence of rickettsia-like symbionts among species of the Aedes scutellaris group (Diptera:Culicidae).

Rickettsia-like organisms were seen by electron microscopy in the oocytes and nurse cells of Aedes hebrideus and A. scutellaris scutellaris and in the oocytes of A. pseudoscutellaris, a Samoan stock of A.
