Historically, this disease manifested itself as ‘sleeping sickness’ in cattle. This disease has been observed in cattle as young as one week of age and as old as 10 years.
Treatment is based on supportive care, and use of antimicrobial therapy. Antibiotics such as tetracyclines, ceftiofur or enrofloxacin may assist recovery. Use of prophylactic feed medication post-arrival may also help reduce death losses.
