Arbobacteria – Pathogens Transmittable by Arthropods

TL;DRAbstract

Anaplasma phagocytophilum, marginatum; Bartonella henselae; Borrelia burgdorferi, afzelii, garinii; Coxiella burnetii; Ehrlichia chaffeensis; Francisella tularensis; Rickettsia prowazekii, akari, rickettsii andYersinia pestis are also known as arbobacteria. Diseases caused by these bacteria are basically zoonoses, i.e. diseases transmittable from animals to humans, and have been known as such for about 100 years (table ​(table1).1). A part of the individual pathogens have not been described until the past few decades. Based on molecular biology analyses, R. prowazekii, Ehrlichia and Anaplasma are categorised as Rickettsiales, while Bartonella is categorised as alpha-2-proteobacteria, Coxiella, Rickettsia grylli and F. tularensis as gamma proteobacteria, and Y. pestis as enterobacteria [1]. Table 1 Vectors for arbobacteria Most arbobacteria grow predominantly intracellularly. However, Borrelia bacteria grow intracellularly and extracellularly, and Yersinia mainly extrac
