Prevalence, hematology, and treatment of balantidiasis among donkeys in and around Lahore, Pakistan

Abstract

The prevalence of Balantidium coli among donkeys in Lahore and adjoining areas was surveyed and a trial conducted to determine the efficacy of two antiprotozoal drugs: secnidazole (Dysen Forte) and Kalonji (Nigella sativa). Four-hundred donkeys were examined, and 73 (18.3%) were found positive for Balantidium coli. A slight decrease in PCV and an increase in Hb values of infected donkeys were found after antiprotozoal treatment. Secnidazole was 89.5% effective for the treatment of equine balantidiasis compared to 40.0% for Nigella sativa. This is the first report of balantidiasis in equines from Pakistan. It is not known if balantidiasis is an emerging problem in equines or whether it is a newly reported infection.
