Summary
Trypanosomiasis caused by Trypanosoma congolense was diagnosed for the first time in Israel in two imported boxer dogs. The dogs rapidly developed severe clinical signs and succumbed to the disease within four days.
Area of Science:
- Veterinary Medicine
- Parasitology
- Infectious Diseases
Background:
- Trypanosomiasis is a significant parasitic disease affecting livestock and occasionally companion animals.
- Trypanosoma congolense is a protozoan parasite transmitted by tsetse flies, primarily found in sub-Saharan Africa.
Observation:
- Two boxer dogs imported from Kenya to Israel presented with acute clinical signs shortly after arrival.
- The dogs exhibited severe anemia, hemorrhages, enlarged lymph nodes, liver, and spleen, along with neurological deficits.
Findings:
- Diagnosis of Trypanosomiasis caused by Trypanosoma congolense was confirmed for the first time in Israel.
- Histopathological examination revealed widespread lymphocytic-plasmacytic infiltration in multiple organs, including skin, brain, meninges, kidney, and liver.
Implications:
- This case highlights the potential for rapid disease progression and high mortality in susceptible hosts.
- The introduction of Trypanosoma congolense into a new geographical region poses a significant biosecurity risk.
- Further surveillance and control measures are crucial to prevent potential spread in non-endemic areas.
