Although no treatment effectively eliminated the tissue stages of H. americanum, treatment with trimethoprim-sulfadiazine, clindamycin, and pyrimethamine followed by long-term administration of decoquinate resulted in extended survival times and excellent quality of life.
Recognition of Hepatozoon canis and Hepatozoon americanum as distinct species was supported by the results of Western immunoblotting of canine anti-H. canis and anti-H. americanum sera against H. canisgamonts. Sequence analysis of 368 bases near the 3′ end of the 18S rRNA gene from each species revealed a pairwise difference of 13.59%.
Operation Canine Lifeline was a tabletop exercise developed by students and faculty of Boston University School of Medicine's Healthcare Emergency Management master's program. The tabletop exercise led to discussion on current protocols for canines working in the field, what occurs if a canine encounters a toxin in the field, and what to do in situations of national security that require working with civilian agencies. This discussion led to the creation of a set of recommendations around providing prehospital veterinary care to government working dogs. The recommendations include a government-run veterinary toxicology hotline for the sole use of the government, issuing handlers deployment kits and preprogrammed smartphones that contain information on the care practices for dogs, and an increased effort for civilian integration, through local emergency medical services, in the emergency care of government canines.
