2004 A new Bartonella species was named in my honor: "Bartonella chomelii (cho.mel'i.i. N.L. gen. n. chomelii in honour of Bruno B. Chomel, who was the first to experimentally demonstrate the transmission of Bartonella henselae by fleas in cats, and to isolate Bartonella bovis from domestic cattle. His studies on Bartonella infection in animals contributed to an improved understanding of epidemiology and vectors of Bartonella-associated disease in animals."
