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.
Fibrous dysplasia (FD) is a skeletal disorder in which bone-forming cells fail to mature and produce too much fibrous, or connective, tissue. Areas of healthy bone are replaced with this fibrous tissue.ibrous dysplasia is caused by a defective gene in the cells that form bone and other affected tissues. The defect occurs at some point after conception, most likely early in fetal development.
