This study aims to investigate potential influence of herbicide utilization on immune responses of the rice frog, Fejervarya limnocharis, living in agricultural area. Frogs were caught from a paddy field with no history of herbicide utilization (reference site) and a paddy field with intensive herbicide utilization (contaminated site) in Nan Province in 2013. After acclimatization, frogs were examined for health, morphometric and gravimetric parameters before subjected to study for a specific immune response (delayed-type hypersensitivity: DTH) and non-specific immune responses (plasma corticosterone level, differential leukocyte count, and numbers of hepatic melanomacrophage and melanomacrophage center (MMC)). The results showed that frogs from the contaminated site had a significantly lower condition factor indicating potential impact on overall health of frog, a significantly higher relative spleen weight indicating potential effect on immune organ, and a significant increase in ovarian weight in a certain season possibly due to effects of herbicide on ovarian growth. Specific immune response as indicated by the DTH response showed the common trend of significantly lower response in frogs from the contaminated site compared to those of the reference site. The results of non-specific immune response showed that there was no significant site-related difference in plasma corticosterone levels. However, neutrophil / lymphocyte (N:L) ratio was markedly reduced in the contaminated site frog during the cool dry season when agricultural activity was present only at the contaminated site. Numbers of melanomacrophage and MMC were markedly elevated in the contaminated site frogs compared to those of the reference site frogs. Significant correlation between numbers of melanomacrophage and MMC vs. atrazine residue was also evident. Overall results suggest that herbicide utilization in agricultural areas could potentially alter immune function of the populated rice frogs.
