The Ralstonia spp. genus is a group of non-fermentative, Gram-negative bacteria often resistant to many antibiotics, which are emerging as opportunistic pathogens frequently associated with infections in hospital settings. We present herein a case of combined R. pickettii and R. mannitolilytica persisting and relapsing bacteraemia, possibly caused by a septic arterial thrombosis secondary to the rupture of an internal carotid artery aneurysm. Microbiology studies showed that both Ralstonia isolates produced biofilm and carried class D oxacillinase genes. When confronted with infections caused by members of the Ralstonia genus, identification to the species level is crucial for correct clinical management, as the two species show different antibiotic susceptibility patterns. Keywords: Ralstonia pickettii, Ralstonia mannitolilytica, bacteraemia, endovascular infection
Background Members of the Ralstonia genus are emerging opportunistic pathogens that include R. pickettii, R. mannitolilytica, R. solanacearum, and R. insidiosa. R. pickettii and R. mannitolilytica have been involved in [...]
