Relevance of direct agglutination test in seroepidemiological survey of Kala-azar in epidemic foci of Bihar.
The performance of direct agglutination test (DAT) was evaluated under field conditions in three endemic districts of Bihar. In three villages of these districts, 197 households were surveyed with a population of 1167 individuals. Out of 1167 individuals, 603 were clinically examined for VL and blood samples of each examined individual were collected for DAT. The proportion of DAT positivity in both males (32.33%) and females (32.94%) was statistically not significant (p > 0.05). The proportion of DAT positivity in all age groups was observed to be similar (p > 0.05). The GMRT was observed highest in active VL cases. Out of 20 DAT positive individuals having fever, 5 were examined parasitologically (bone marrow aspiration) and in three cases positivity was observed. This showed the relevance of DAT in early diagnosis of visceral leishmaniasis and usefulness of DAT in field conditions.
