ABSTRACT
Two cases of paragonimiasis have been reported from Srisangval Hospital, Mae Hong Son Province, Thailand. These two patients (Thai-Karen) resided in Nam-Piang-Din, Mae Hong Son. The preliminary survey for epidemiological data in Nam-Piang-Din, Mae Hong Son revealed that most of Thai-Karen villagers had the habit of eating raw crabs and fresh water prawns. A survey for intermediate and reservoir hosts are still in progress and this area can be considered as an additional area for paragonimiasis in Thailand.

The microfilariae found in carriers at Tak Province, Northwestern Thailand were morphologically and morphometrically studied. It was found that the parasites conformed to that of W. bancrofti microfilaria. The microfilarial periodicity as determined from four carriers was found to be nocturnally (early evening) subperiodic type showing a distinct peak at 1800 hours.

It was reconfirmed that L. deliense was the most dominant chigger during the rainy season in northern Thailand. Overall prevalence of IgG antibody against R. tsutsugamushi among the rural villagers in the northern most part of Thailand was nearly 60% at the level over 1 : 10 by an indirect immunofluorescent test. The level of IgG and IgM antibody titers was considerably high as greater than or equal to 1 : 2560 in some sera, but did not markedly vary by age groups or sexes. Based on detection of IgM antibody, the probability of new or reinfections were considered.
