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.
Now, the most common cause of joint replacement loosening is due to wear of the implant surfaces, and the subsequent weakening of surrounding bone. This problem is called osteolysis, and it causes the hip replacement to loosen over time.
