Abstract
A 30-year-old male, who had undergone renal transplantation from a deceased donor on august 2017 with a stable graft function, presented with the complaints of fever and an ulcer on the right foot. On examination, the patient was malnourished and febrile, on inspection the ulcer was irregular approximately 3 x 2.5 x 3 cm in size, situated on the lateral aspect of dorsum of the right foot with yellowish white discharge, creamy in consistency. Pus for culture and sensitivity revealed the growth of Enterobacter spp which was sensitive to almost all the antibiotics used for Gram negative bacilli. Ziehl-Neelsen method of staining by using 25 % sulfuric acid as a decoloriser showed the presence of acid-fast bacilli in all smears. The pus sample was sent for Cartridge Based Nucleic Acid Amplification (Gene Xpert) test which was positive for Mycobacterium tuberculosis with negative rifampicin resistance.
