There are two foulbroods; American and European. The European foulbrood more or less managed itself but the American foulbrook is catastriphic.

American foulbrood (AFB) is caused by the spore-forming bacterium Paenibacillus larvae. Seeing a spotty brood pattern is the first sign that the hive is in trouble. Off-color larve is another clue; usually dark brown to black and sunken to the bottom of the cell; and the cells stink, hence the name foulbrood. The spores are spread to the larve through contamnated food fed by the nurse bees. Regrettably, burning all your equipment and humanely killing the bees is the only course of acton.

European foulbrook (EFB) is an infectuous brood dieease caused by the bacterium Melissococcus pluton, also knows as a stress disorder, As with AFB, seeing a spotty brood patters in a sign of trouble. Upon closer inspection, scale from the dead larve can be seen the cells. Over come this by requeening with a hygentic queen and feeding the bees.

Spotty brood pattern, sunken cells and a bad smell are a few signs of American foul brood. To properly diagnose stick a thin stick, think pine straw or toothpick, into the capped cell. If it  has a stringy gooy look to it then you have AFB. The key is stringy.

Not all is lost though, you can shake all the bees into a new box, a false swarm, and they will recover. The frames are loss. the hive bodies can be 'cleaned with fire, using a fan torch. There are studies using this method out of Germany and most colonies recover fully.

American foulbrood (AFB) is a fatal bacterial disease of honey bee brood caused by the spore forming bacterium Paenibacillus larvae. It is not a stress related disease and can infect the strongest to the weakest colony in an apiary. Infected brood usually die at the pre-pupal or pupal stage. Heavy infections can affect most of the brood, severely weakening the colony and eventually killing it. The disease is not able to be cured, meaning that destruction of infected colonies and hives or irradiation of infected material is the only way to manage AFB.
