This module provides an overview of Bartonella spp. infection, both pathogenic and species-adapted, in various hosts and reservoirs, including bats, cats, dogs, and people.

Learning objectives:

  1. Describe the flea-transmitted Bartonella spp. for which feral and pet cats can be reservoir hosts
  2. Describe the canine-adapted Bartonella spp. that have been implicated in association with human Bartonelloses
  3. Describe the role of rodent species and bats as potential reservoirs of human infection

Learners may receive credit for this course through either the Accreditation Council for Continuing Medical Education (ACCME) or the American Academy of Family Physicians (AAFP).

Invisible International is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education for physicians. This course is approved for AMA PRA Category 1 Credit™️ – 1.0 Credits.

Additionally, this session, Bartonelloses reservoir hosts: Bats, cats, dogs, mice and men, is approved for 1 enduring AAFP Prescribed credit.

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.

The AAFP has reviewed One Health Medical Education for a Changing Climate, and deemed it acceptable for AAFP credit. Term of approval is from 01/02/2023 to 01/01/2024. Physicians should claim only the credit commensurate with the extent of their participation in the activity.
