While the organism is not normally found in healthy bees, it has occurred exceptionally. In these cases the infection has possibly been present in such hives, and it is cer- tain that many cases of paralysis and dysentery recorded in bees have been due to paratyphus. "This somewhat infectious and ma- lignant disease can be spread (1) by purchase of infected bees and of apparently healthy bees that orig- inate from a hive that sometime pre- viously has been attacked by the dis- ease; (2) through foreign infected males; (3) through beekeepers car- rying the infection from attacked apiaries to healthy ones; (4) through infected frames, tools or hives.
