Abstract

Bed bugs are small hematophagous insects. They are found in temperate and tropical climates around the world. Their vectorial capacity for several pathogens, including Bartonella spp., has been suspected. An experimental study of artificial infection of Cimex lectularius with Bartonella quintana and Bartonella henselae bacteria was developed to evaluate the ability of MALDI-TOF MS to simultaneously identify bed bugs and their infectious status. This experimental study confirmed the ability of MALDI-TOF MS to identify bed bugs. In addition, it was able to differentiate between control bed bugs, bed bugs infected with Bartonella quintana and bed bugs infected with Bartonella henselae, with an identification percentage above 90%.
