A method is introduced for the analysis of nearest neighbor distances between immunogold particles marking proteins on electron micrographs. Deviation from the distribution that is predicted by chance indicates co-localization of the labeled speci...

The effectiveness of clavulanic acid, sulbactam, quinacillin sulfone, and the carbapenems MM13902 and MM4550 as inhibitors of TEM-2 beta-lactamase in growing cultures of gram-negative bacteria has been studied. Each of these beta-lactams inhibited...
