Аннотация
PURPOSE: Lautropia mirabilis is a Gram-negative, facultative anaerobic coccus, which has been detected mainly in respiratory sites of immunodeficient patients suffering from HIV or cystic fibrosis. To date, knowledge about the pathogenicity of L. mirabilis is spare due to the small numbers of documented cases.
METHODS: We present a literature review and report the case of a 39-year-old female diagnosed with common variable immunodeficiency (CVID) with IgG and IgA deficiency suffering from a sepsis with L. mirabilis. As no fully closed L. mirabilis genome besides the type strain was available to date, we additionally performed complete genome sequencing of L. mirabilis.
RESULTS: The patient was admitted to our hospital with recurrent episodes of fever. Here, we detected L. mirabilis in two different blood cultures. The bacterium was tested susceptible to and treated with meropenem. As the origin of L. mirabilis sepsis, we observed an active periodontitis likely due to impaired IgA levels and mucosal insufficiency as a consequence of CVID. Whole genome sequencing of L. mirabilis revealed several genes important for host cell invasion and intracellular survival of the pathogen.
CONCLUSIONS: Our case highlights the importance of L. mirabilis in immunocompromised patients also in other compartments than the respiratory tract.
