Abstract

ABSTRACT Of 200 individual Xenopsylla cheopis fleas removed from Rattus norvegicus rats trapped in downtown Los Angeles, CA, 190 (95%) were positive for the presence of Bartonella DNA. Ninety-one amplicons were sequenced: Bartonella rochalimae -like DNA was detected in 66 examined fleas, and Bartonella tribocorum -like DNA was identified in 25 fleas. The data obtained from this study demonstrate an extremely high prevalence of Bartonella DNA in rat-associated fleas.
