Efficacy of permethrin-impregnated uniforms in the prevention of cutaneous leishmaniasis in Iranian soldiers

One approach for prevention of cutaneous leishmaniasis is creation of a barrier between the insect vector [phlebotomus] and the host. Many, but not all, researchers claim that permethrinimpregnated uniforms are effective for prevention of cutaneous leishmaniasis. We determined the efficacy of permethrinimpregnated uniforms for prevention of cutaneous leishmaniasis among Iranian soldiers. 324 soldiers were randomized into two equal groups. 272 soldiers completed the study. In Group A, 134 soldiers were issued permethrin impregnated uniforms. In Group B, 138 soldiers were issued uniforms washed in water. The soldiers wore uniforms day and night for 3 months, and were observed for an additional 6 months. All of the soldiers remained during this 3 months in the leishmaniasis-endemic area of Isfahan. 9 [6.5%] of 138 soldiers wearing control uniforms and 6 [4.4%] of 134 soldiers wearing permethrin-impregnated uniforms acquired cutaneous leishmaniasis. The difference between the two groups was not statistically significant. Permethrin-impregnated uniforms may not be effective in prevention of cutaneous leishmaniasis

Distribution of phage types and transferable drug resistance in shigellae [1962-73]

A total of 610 strains of Shigellae isolated from cases of diarrhea in Iran during 1962-73 were studied with respect to their phage type, as well as antibiotic resistance and transferable drug resistance along with serotyping. It was shown that there was some relation between serotypes and phage types but no association could be found between phage types and resistance pattern
