The 1,3,4-thiadiazole derivatives (2-amino-1,3,4-thiadiazole, acetazolamide, sulfamethizole) have been studied experimentally in the solid state by (1)H-(14)N NQDR spectroscopy and theoretically by Density Functional Theory (DFT). The specific pattern of the intra and intermolecular interactions in 1,3,4-thiadiazole derivatives is described within

Stenotrophomonas (Xanthomonas) maltophilia is a nonfermentative, gram-negative bacillus that is widely distributed in natural and human-made environments. In the nonhospital setting it is an uncommon pathogen, typically causing soft tissue infection of contaminated wounds. In the hospital setting, particularly among
