Bacillus apiarius Katznelson (1955)
Gram variable, 0.7-0.9 / 3.0-4.5 μm,  motile with  peritrichous and abundant flagella.
Ellipsoidal, central or paracentral spore, swelling the sporangium. Spores have thick
walls; they appear to be rectangular in swollen sporangia.
Nonpigmented, round, smooth, translucent, 1 mm diameter colonies on agar
medium. Growth temperature  from  15 ºC  to  40 ºC (optimum 28 ºC).
Grow in anaerobic agar, in nutrient broth and at 5.7 pH.
Grow in 5% NaCl media but not in 7% or 10% NaCl.
Isolated from honeybees, their larvae and their hives. Resistant to lysozyme.
Isolated from honeybees, but is not an insect pathogen.
