Introduction:
Rapidly growing mycobacteria (RGM) are ubiquitous and are usually considered as saprophytes, and have been recovered from the environment, particularly in dust, watery soil and water distribution systems. However, Mycobacterium massiliense is a rare causative agent of ocular infection.
Case Presentation:
We report a case of M. massiliense in a 44-year-old female with signs and symptoms of a corneal ulcer. We carried out PCR-based DNA sequencing targeting the hsp 65 gene for the identification of M. massiliense. To confirm the identification, we also performed PCR-based RFLP targeting the hsp65 gene and PCR-based DNA sequencing targeting the internal transcribed spacer region, which showed 97 % nucleotide identity with M. massiliense.
Conclusion:
To the best of our knowledge, this is the first study in India to report the detection of M. massiliense from a corneal biopsy.
