He was noted to have a fluid collection over the left lateral hip and hip X-ray showed loosening of the prosthetic hip stem indicative of a prosthetic joint infection (PJI). He subsequently underwent removal of the THA and insertion of an antibiotic spacer. He was discharged on intravenous ceftriaxone for presumed culture negative PJI. Intraoperative acid fast bacillus culture later grew <jats:italic>Mycobacterium tuberculosis complex<\/jats:italic>, which was then differentiated to <jats:italic>M. bovis<\/jats:italic>. The <jats:italic>M. bovis<\/jats:italic> infection was thought to be a complication of the patient\u2019s prior BCG therapy. He was initially started on isoniazid, rifampin, pyrazinamide and ethambutol pending cultures and sensitivities; pyrazinamide was discontinued after <jats:italic>M. bovis<\/jats:italic> was isolated on culture and susceptibility data confirmed the expected inherent resistance of <jats:italic>M. bovis<\/jats:italic> to pyrazinamide.
