A 53-year-old man with a past medical history of total arch replacement surgery and severe aortic regurgitation presented with a 1-month history of persistent general malaise, anorexia, body weight loss and night sweats. His recent history included gingival hyperplasia for 6 years, gingivitis after tooth extraction 3 years before, prolonged inflammatory status for 4 months, fundal hemorrhage and leg tenderness for 2 months. A pathogen was detected from blood culture, but conventional microbiological examination failed to identify the pathogen...

Coxiella burnetii, the causative agent of Q fever, may cause culture-negative vascular graft infections that can be diagnosed by serology and molecular biology. We present a case of vascular graft infection detected by positron emission tomography (PET) scanner. The presence of C. burnetii was confirmed by high antibody titers and positive polymerase chain reaction specific for C. burnetii. This report emphasizes the relevance of the PET scanner in the diagnosis of infection when used in association with Q fever serology and molecular biology for the etiological identification of C...

BACKGROUND: Abiotrophia and Granulicatella species, previously referred to as nutritionally variant streptococci (NVS), are significant causative agents of endocarditis and bacteraemia. In this study, we reviewed the clinical manifestations of infections due to A. defectiva and Granulicatella species that occurred at our institution between 1998 and 2004. METHODS: The analysis included all strains of NVS that were isolated from blood cultures or vascular graft specimens...

BACKGROUND: Coxiella burnetii, the causative agent of Q fever, may cause culture-negative vascular graft infections. Very few cases of C. burnetii infection of a vascular graft have been reported. All were diagnosed by serology. CASE PRESENTATION: We report the first case of Coxiella burnetii vascular graft infection diagnosed by broad-range PCR and discuss the diagnostic approaches and treatment strategies of chronic C. burnetii infection. CONCLUSION: C...

Human infections caused by Lactobacillus spp. are rarely reported in the literature. Underlying conditions are frequently reported, and identification of lactobacilli to the species level remains rare. A case of Lactobacillus casei septicaemia secondary to a vascular graft infection is reported. The 16S rRNA sequencing technique was used to definitively identify Lactobacillus casei.
