"Ropiness" of brood
Introduction to the ropiness test
AFB infected larvae at both pre pupal and pupal stages display a characteristic “ropiness” when a small stick is used to slightly stir the diseased tissue in the cell and then the stick is slowly removed (Fig. 29).
The ropiness is thought to be caused by the presence of long chains of the vegetative stage of AFB bacteria intertwining and producing an elastic, binding effect.

There’s a lot of good information here, telling you everything you need to know about recognising AFB: the visual symptoms, smell of AFB and more.
New Zealand beekeepers have a number of legal obligations that must be met regarding AFB disease. Read the shortened list in summary, here.
Most hives become infected because bees, honey or equipment have been put into a hive from another hive that is infected with AFB. Lower your chances of an AFB infection by reading this section.
