The results of four in vitro germicidal test methods are compared with the conventional 4-mm. loop method of test. The four variations described are subjected to three methods during the test period; i.e., stationary, slow rotation, and the customary initial swirl. Four selected test microorganisms and eight chemical compounds are employed in these studies. The “total swirl” method of test gives more critical killing end points, is more consistent, and more nearly measures complete germicidal effect than the 4-mm. loop method of test. |
