The survey data of microfilarial periodicity of 2 species of filariae Brugia malayi at 4 localities, Mahang and Lampihong in South Kalimantan, Bengkulu in South Sumatra, Palolo in Central Sulwesi, and the species of Brugia timori at 2 localities, Flores and Alor Islands in Nusa Tenggara were analysed by using Aikat and Das's modified statistical method. Nine cases at Mahang and five cases at Lampihong were recognized as same group of non-periodic B. malayi and 1 case at Mahang was considered to be nocturnal subperiodic B. malayi by their parameters estimated by the wave equation, the amplitude (a), the peak hour of microfilaria density (k) the periodicity index (D) and the test of equality for comparison of two series of data. The data of 9 cases from Bengkulu and 11 cases from Palolo were similarly analysed and recognized as the nocturnal periodic type of B. malayi. The data of 5 cases from Flores Island and 5 cases from Alor Island were also recognized as the nocturanal periodic type of B. timori. Thus, in these observations the non periodic strain of Brugia malayi was detected in South Kalimantan. Further studies on the principal vectors and their bionomics should be carried out.
