Question: how many infectious diseases are transmitted by triatominae? 
Topic entities:
Triatominae: m.060t35
Logical form: (COUNT (AND medicine.infectious_disease (JOIN (R medicine.type_of_infectious_agent.diseases) (JOIN (R medicine.infectious_disease.infectious_agent_type) (JOIN (R medicine.vector_of_disease.disease) m.060t35)))))
Actions:
get_relations(m.060t35)
get_neighbors(m.060t35,medicine.vector_of_disease.disease)
get_relations(#0)
get_neighbors(#0,medicine.infectious_disease.infectious_agent_type)
get_relations(#1)
get_neighbors(#1,medicine.type_of_infectious_agent.diseases)
count(#2)
Answer:
30
