The patient underwent valve replacement surgery and active antibiotic treatment against Gram-negative cocci (Piperacillin Tazobactam then Ceftriaxone) for a total duration of 42 days with a favourable outcome. The causative agent was which was identified on the infected valve by sequencing of 16S ribosomal RNA. To our knowledge, this is the first described case of a infective endocarditis on a pulmonary valve. Initially, serologies performed in clinical settings by immunofluorescence for antibodies showed a major increase in phase I IgG titers at 1024 (normal values &amp;lt;16) corresponding with the diagnostic criteria for Q fever endocarditis. However, this diagnosis could not be confirmed by the National Reference Center, making it the first reported case of a false positive serology for during an infection due to spp.&lt;/p&gt;
