Research and development of potent and effective antimicrobial agents represent one of the most important advances in therapeutics; the main aim of these efforts is not only control the serious infections, but also prevention and treatment of some infectious complications of other therapeutic modalities. A series of 5-(2-aroyl)aryloxy methyl-2-phenyl-1,3,4-oxadiazoles were screened for their antibacterial and antifungal activities. Anti-bacterial activity against B. cereus, S. aureus, B. subtilis, S. aureus (MRSA), E. aerogenes, M. luteus, K. pneumonia, P. aeruginosa, S. typhimurium, E. coli, paratyphi-B, P. vulgaris bacterial strains and anti-fungal activity against C. albicans, A.niger, F.solani, A.flavus, B.cinerea, C.krusei, M. pachydermatis, C.parapsilosis, F.moniliforme, C.gloeosporioides fungal strains were carried out. The bioassays indicated that most of the synthesized compounds showed potential antibacterial and anti-fungal activity
