 Without physical evidence of tuberculosis by the absence of the species "Mycobacterium tuberculosis", the physicians misdiagnosed her with tuberculosis; but the testing of the patient’s bronchial lavage found coccobacillary, acid-fast microbes.After further testing, the isolate organism showed high similarity of up to 100% to "Mycobacterium elephantis".This demonstrates the difficulty of diagnosing humans with tuberculosis in different geographic areas.
