Description

This module introduces a new postulate of comparative infectious disease for elusive, slow-growing, zoonotic, vector-borne diseases like Bartonella spp infection and describes the comparative features of Bartonellosis in dogs and people with particular attention to geographic and occupational risk factors.

Learning objectives

  1. Describe a new postulate of comparative infectious disease
  2. Describe the comparative disease features of Bartonella spp infection in dogs and people
  3. Describe the geographic and occupational risk factors for Bartonella spp infection

Accreditation Statement

This session, Bartonelloses and comparative infectious disease causation, is approved for 1.0 enduring AAFP Prescribed credit.

The AAFP has reviewed One Health Medical Education for a Changing Climate, and deemed it acceptable for AAFP credit. Term of approval is from 01/01/2025 to 12/31/2025. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

AAFP Prescribed credit is accepted by the American Medical Association as equivalent to AMA PRA Category 1 credit(s)™ toward the AMA Physician’s Recognition Award. When applying for the AMA PRA, Prescribed credit earned must be reported as Prescribed, not as Category 1.
