Description

This module provides an overview of key vectors and modes of transmission associated with Bartonella spp. infection, with special attention to ongoing debates surrounding tick transmission, perinatal transmission, and other modes, like transfusion and needlesticks.

Learning objectives:

  1. Describe the vectors that are known to be competent for Bartonella spp. transmission
  2. Describe the historical controversy and current understanding of tick transmission of Bartonella spp.
  3. Describe transmission of Bartonella spp. by modes other than vectors

Accreditation Statement

This session, Bartonelloses: Vectors and other modes of transmission, 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.
