The presence of large numbers of bacteria in the food seems not to injure bees; but if a drop of water that contains the bacteria is spread over the entrance to the breathing organs (spiracles), dis- ease and death from septicemia usually result. The disease does not spread readily from sick or dead bees to healthy ones unless plenty of moisture is present. The bacteria are soon killed by drying, and the disease rarely occurs under dry conditions. Several other species of bacteria and yeasts cause septicemia when they are placed in the blood of bees by puncturing the body covering, but they seem to be unable to gain entrance to the blood of uninjured Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Burnside, C.
