Lippincott2 recorded a mild case of Flexner's dysentery in a technician who had accidentally drawn a suspension of Shigella paradysenteriae (Flexner) into her mouth while doing an agglutination test on a recently isolated strain.Shiga dysentery is ordinarily transmitted by means of contaminated food or water; it occurs sporadically or in small epidemics, as among army populations; the primary source of the bacteria is commonly a carrier or an active case. The case reported here is deemed of interest not simply because it resulted from a laboratory infection but particularly because of the unusual opportunity afforded us to work out the
