Comparison of Substance Sources in Experimental Antimicrobial Susceptibility Testing

Funding is often a constraint when planning research, especially in countries where basic research underfunded. Researchers must take into account these limitations, e.g., relation to the selection of appropriate reagents, source which may affect study’s final results. The aim this article was compare results bacteria susceptibility testing using three different sources antimicrobial: pure powder available from supplier and two tablet formulations with excipients. chosen substance furazidin (nitrofuran derivative). tested on group 45 uropathogenic Enterobacterales both microdilution disk diffusion methods. obtained indicated that despite relatively higher price, appeared be best for scientific purposes, quantitative determinations.
