[The aggregation ability of the plague microbe].

open access: yesMeditsinskaia parazitologiia i parazitarnye bolezni, 1996
Hemoglobin enhances the aggregation of the plague bacillus in fluids (p > 0.99), the proportion of its action on this process being 46.7%. The aggregated forms of the plague bacillus as conglomerates are of greater value in the virulence of the plague bacillus for white mice than are a series of plague bacilli or single microbes, which is an important ...
