M. elephantis, but there has been significant findings. After Shojaei et al. performed experiments testing properties of the 484t strain, aerobic metabolic properties were found. M. elephantis is catalase, nitrate reductase, and urease positive as well as weakly acid alcohol fast. The 484t strain was found to be negative for tellurite reduction as well as activity with aryl sulphatase. The optimal growth temperature for this species is about 42° Celsius with its first strains showing at the third day of growth at this temperature. Growth at lower temperatures around 30° Celsius occurs, but growth is minimal over 45° Celsius. Growth of this organism does not occur at temperatures above 52° Celsius. Although this organism is slower than average rapid growing Mycobacterium, growth under 7 days classifies this species as a rapid grower. Stunted growth is shown in the presence of isoniazid, rifampicin, and few other drugs. Genome Mycobacterium elephantis’s has been researched and studied to provide some insights on the genomic nature of this organism. A strain of M. elephantis, Lipa, contains a G-C content of 67.8%, and a genome size of 5.19 Mb. 250 pseudogenes are also found in this strain. The 484t strain’s (same as DSM 44368) 16S rRNA gene sequence as compared to other rapid growing mycobacterium showed a mean 96.7+ 0.5% similarity. It also showed a 96.2+ 0.4% similarity to slow growing mycobacteria. The closest neighbors that show the most similarity to M. elephantis are M. confluentis at 97.8% and M. phlei at 97.7%. Although closely related, strain 484t shows 29 and 30 nucleotide differences in the familiar species. Significance Mycobacterium elephantis has the potential to impact diagnostic evaluation when patients display untraceable tuberculosis symptoms. A patient in Asia was hospitalized due to chronic respiratory disease. A chest X-ray showed signs including a shadow in her right region of her chest, which is known to be a common sign of tuberculosis . 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. Misdiagnosis can be a huge factor in patient care and rehabilitation, and further research on this organism can diminish this problem. Mycobacterium elephantis should
