Applied studies on the viability of El Tor vibrios.

The viability of El Tor vibrios was tested at various temperatures in foodstuffs, kitchen utensils, and water after these materials had been directly contaminated with stools of cholera patients or carriers from the Philippines, collected in 1963-64. The period of survival of vibrios in foodstuffs was 2-5 days at room temperature (30 degrees C-32 degrees C) and as long as 9 days under refrigeration (5 degrees C-10 degrees C). Vibrios survived even longer in refrigerated water. The period of survival was shorter for all materials contaminated with carriers' stools, which contain fewer vibrios. Chlorinated lime was more effective than potassium permanganate as a decontaminant.

Pararosaniline pamoate (CI-403-A) in the treatment of Schistosoma japonicum infection in the Philippines.

Trials have been carried out, first on a relatively small scale among patients in Manila and later on a larger scale among domiciliary patients in an area of endemic schistosomiasis in Leyte Province, Philippines, with various dosage schedules of pararosaniline pamoate (CI-403-A) to determine that drug's efficacy and optimum dosage against Schistosoma japonicum infection.Given orally in gelatin capsules, the drug was well tolerated even in children, with few side-effects, and was both curative and suppressive when administered in a maximum dosage of 35-40 mg/kg body-weight per day for as many as 52 days spread over a total treatment period of 203 days.The authors recommend its use for mass treatment, especially among schoolchildren, in combination with other established schistosomiasis control measures-health education, environmental sanitation, and snail control.

A controlled field trial of the effectiveness of cholera and cholera El Tor vaccines in the Philippines.

A controlled field trial on some 584 000 people in an endemic cholera El Tor area in the Philippines demonstrated that cholera vaccines gave moderate protection of short duration. Injection of a single dose of vaccine prepared from either Vibrio cholerae or El Tor vibrios gave over 50% protection for the first 2 months. The immunity conferred by the V. cholerae vaccine declined rapidly after 3 to 4 months. The effectiveness of the El Tor vaccine continued for 6 months. An oil-adjuvant vaccine prepared from V. cholerae conferred an equally high degree of protection for a longer period of time, but, owing to severe vaccination reactions, its use could not be recommended.
