AMERICAN FOUL BROOD. American foul brood is also a bacterial disease caused by Bacillus larvae, and attacks the brood at a later stage than European foul brood. It usually shows itself at the time the larvae are mature and pupating, when the cells are sealed or capped. The diseased cells later become sunken and if broken open the contents emit an offensive odor, and have a peculiar stringy or ropy consistency. Shaking into clean hives, destroying all infected combs and disinfecting the old hives is the treatment. Almost the whole danger of a recurrence is careless treatment and reinfection from infected combs and honey. Some authorities are recommending and using an alcohol-formalin solution containing 20 per cent. formalin, in which they soak the combs to sterilize them, after which they can be safely used. This may prove of great value in stamping out the disease.

Of the 953 apiaries and 8,929 colonies inspected in 1924, 10 apiaries and 20 colonies were found diseased with American foul brood. This is 1.04 per cent. of the apiaries and .22 per cent of the colonies, a slight increase in percentage of the apiaries and decrease in that of the colonies over last year. With American foul brood there has never been any gradual decrease as in the case of European foul brood, but spasmodic outbreaks have occurred here and there since 1914. The following table will show the percentages of apiaries and colonies found diseased with American foul brood since the beginning of inspection work in Connecticut.

During 1924, American foul brood was found in the towns of Greenwich and Shelton, Fairfield County; Naugatuck and Wallingford, New Haven County; Clinton, East Hampton and Haddam, Middlesex County; Old Lyme, New London County; Thomaston and Washington, Litchfield County. The disease was not found in any apiaries inspected during the season in Hartford, Tolland or Windham Counties.

The system of controlling this disease in some of the States is that known as the "area clean-up" method, and an attempt is made to eradicate the disease, working around the centers of infection. A movement has been started to procure Federal cooperation in this work.
