Background: Whipple disease is a chronic infection caused by Tropheryma whipplei. Trimethoprim-sulfamethoxazole is recommended for treatment of Whipple disease but is associated with treatment failure. T.

Nanobacteria are mineralo fetuin complexes.

"Nanobacteria" are nanometer-scale spherical and ovoid particles which have spurred one of the biggest controversies in modern microbiology. Their biological nature has been severely challenged by both geologists and microbiologists, with opinions ranging from considering them crystal structures to new life forms. Although the nature of these autonomously replicating particles is still under debate, their role in several calcification-related diseases has been reported.
