Injury. Booklice feed on molds and will overrun cereals and similar materials that support mold growth. Their presence, therefore, is a nuisance and can render some foods unfit. The starchy paste of wallpaper and books also can support mold growth or may be attacked directly by booklice.
Special Notes. In young dogs, hip dysplasia usually is caused by conformational abnormalities that cause a âpoor fitâ between the head of the femur and the pelvic acetabulum, which in turn causes laxity of the hip joint.
General Discussion. Kniest dysplasia is one of several forms of dwarfism that is caused by a change (mutation) in a gene known as COL2A1. This gene is involved in the production of a particular protein that forms type 2 collagen, which is essential for the normal development of bones and other connective tissue.
