Asad Ullah Khan

Asad Ullah Khan is an Indian microbiologist, biochemist and a professor at the Interdisciplinary Biotechnology Unit of the Aligarh Muslim University.

He is known for his studies on multidrug resistant clinical strains as well as for the first sighting in India of Aligarh super bug (NDM-4), a variant of New Delhi metallo-beta-lactamase 1 (NDM-1).

[2] Khan's research focus is on developing new inhibitors against multidrug resistant clinical strains with special interest on extended spectrum beta lactamases (ESBL) such as NDM-1 and CTX-M, using QSARR modeling and structure-based virtual screening methods.

[1] The team led by him collect Escherichia coli and Klebsiella pneumoniae strains from hospital and community-acquired infection sites and it was during one of those explorations that he discovered a variant of New Delhi metallo-beta-lactamase 1 named NDM-4, more commonly known as Aligarh super bug, in the sewage drains of Jawaharlal Nehru Medical College, Aligarh, in 2014.

[3][4] This was the first recorded sighting of the antibiotic-resistant super bug in India;[note 1][6][7] the finding was later disclosed by Khan in an article published in the Journal of Medical Microbiology.
