Abstract

PAULA, Cristiane Coimbra de; BITTENCOURT, Walkiria Shimoya  and  LEITE JUNIOR, Diniz Pereira. Contact lenses causing conjunctivity by Ralstonia Pichettii. Rev. bras.oftalmol. [online]. 2019, vol.78, n.1, pp.49-51. ISSN 0034-7280.  https://doi.org/10.5935/0034-7280.20190011.

The present report reports a case of conjunctivitis caused by Ralstonia pichettii in an immunocompetent patient wearing a contact lens. The bacterium isolated from the solution used to disinfect R. pichettii does not belong to the human microbiota but infects immunodepressed patients and is present in aqueous solutions. There is no standardization of sensitivity for this bacterium and few antibiotics have been tested for non-fermenting glucose bacteria. Due to the reduced antimicrobial sensitivity profile demonstrated by R. pichettii, it is important to correctly identify this etiologic agent in conjunctivitis and keratitis. This case report illustrates that R. Pickettii is a more important pathogen than previously thought.

Keywords : Eye infections; Bacteria; Conjunctiva; Ralstonia pichetti; Contact lenses; Case reports.
