TREATMENT OF AMERICAN FOULBROOD 



The treatment of American foul- 

 brood consists primarily in the 

 elimination or removal of the cause 

 of tlie disease. Tn treating this 

 disease the aim of the manipulation 

 is to destroy all of the bacteria of 

 American foiillirood ]>y the removal 

 of all infected material from the 

 colon\', and in compellinji; the liees 

 to take a fresh start l)y building 

 new comb and p-athering fresh 

 .stores. This is done by brushing 

 the 1)ees from the old combs into 

 a clean hive. 



Time of Treatment : The brush- 

 ing treatment should be given dur- 

 ine' a honey flow, so that other 

 bees in the apiary will not be in- 

 clined to roll. 



Operations— 1 : The colony, in 

 the evening after bees have quit fly- 

 ing, .should be moved out of the api- 

 ary a distance of at least two hun- 

 dred fe(_'t in a so-called liospital 

 yard and left undisturberl a few 

 days until the bees lunc marked 

 their new location. 

 •2. Sele,-l an empty hive body that is bee-tight to rec-ive the diseas- 

 '^d combs, and nail a tight bottom to it. Then place a cover on it. 



■•!. nave a brood chamber containing full sheets of foundation 

 reach-. 1 lace an empty hive on this to brush the bees into. 



4. Place the clean hive body containing full .slieets of foundation 

 with bo torn board and queen excluding zinc over the entrance in place 

 of the diseased colony which has been moved back a few feet The 

 -lueen-oxelnding zinc will help to keep the colony from abscondinc^ '
