Acute dacryocystitis secondary to Burkholderia cepacia and Sphingomonas paucimobilis mixed infection: A novel case report.

Acute dacryocystitis caused by Burkholderia Cepacia and Sphingomonas Paucimobilis is uncommon. To the best of our knowledge, presence of mixed pathogens Burkholderia Cepacia and Sphingomonas Paucimobilis causing acute dacryocystitis in immunocompetent patients never been described. Burkholderia Cepacia and Sphingomonas Paucimobilis been reported only as a single microorganism causing other ocular infections in immunocompromised patients. Middle age, medically free female patient, presented to the emergency department at our hospital, with a history of nasolacrimal duct obstruct (NLDO) complaining of inferior preocular swelling associated with localized pain diagnosed as acute dacryocystitis. She was on oral Amoxicillin/clavulanic acid, oral Nitroimidazole antimicrobial and topical Tobramycin from elsewhere. However, no improvement had been noticed. We kept the patient on the same medications and swaps taken for culture and sensitivity. Patient presented to the first follow-up appointment with no improvement on her status. Culture and sensitivity revealed 2 pathogens: Burkholderia Cepacia and Sphingomonas Paucimobilis. We have changed the antibiotic to oral Trimethoprim/ Sulfamethoxazole as it showed positive sensitivity to the pathogens based on the sensitivity chart. Second follow-up appointment patient's condition improved.
