Bivitellobilharzia nairi is a poorly understood trematode belonging to the family Schistosomatidae that has a profound impact on its host species, the elephant. The pernicious effects of the different life stages of this parasite can often be fatal. The first reports of schistosomosis in African and Asian elephants were published by Vogel and Minning (1940) and Mudaliar and Ramanujachari (1945), respectively. The morphologies of ova and adult helminths of B.nairi, the schistosome affecting Indian elephants (Elephas maximus indicus) have been described in detail by Rao and Hiregaudar (1935), Sundaram et al. (1972), Chandrasekharan (1989), Islam (1994) and Vimalraj et al. (2012). According to Bhoyar et al. (2014), the infection remains subclinical in most cases and is only discovered upon post-mortem examination. More recently, Devkota(2015) found that Bivitellobilharzia spp. infects both, captive and wild Asian elephants. Karawita et al. (2015) claimed to report the first death of an Asian elephant due to caecocolic intussusception on account of schistosomosis
