The mouse footpad model.
It may be hard, now that Mycobacterium leprae is just another entry in the large catalogue of pathogens whose DNA sequence is known and leprosy is just another treatable bacterial disease, to understand the excitement generated by the mouse footpad model when it was introduced. It is, after all, not obviously exciting: 10,000 bacilli are injected into the hind footpad of a normal mouse. This is...
متن کاملFootpad dermatitis in poultry.
Footpad dermatitis (FPD) is a condition that causes necrotic lesions on the plantar surface of the footpads in growing broilers and turkeys. This condition not only causes downgrades and condemnations of saleable chicken paws, the portion of the leg below the spur, but is also an animal welfare concern in both the United States and in Europe.. Revenue from chicken paws in 2008 alone was worth $...
متن کاملEffect of Litter Moisture on the Development of Footpad Dermatitis in Broiler Chickens
Broiler chicks were reared on either wet litter or dry litter to compare the development of footpad dermatitis (FPD). Broilers reared on wet litter first developed FPD at 14 days of age. Their FPD scores increased sharply after 21 days of age, reaching 2.92 at 42 days. In broilers reared on dry litter, FPD was first observed at 28 days of age, and the FPD score was only 0.70 at 42 days. When 21...
متن کاملInduction of the delayed footpad and wattle reaction to killed Staphylococcus aureus in chickens.
Two experiments were conducted to induce the delayed footpad reaction (DFR) to killed Staphylococcus aureus antigen. In Experiment 1, tracheal, cloacal, and choanal swabs were collected from chickens prior to sensitization with S. aureus to determine the carrier status of S. aureus. The second experiment compared the DFR to the delayed wattle reaction (DWR). Chickens were subjected to single or...
متن کاملUltrastructural changes in cells of the mouse footpad infected with Mycobacterium leprae.
Ultrastructural changes in cells of the mouse footpad are described which occurred during the log phase of multiplication, the plateau, and the stationary phase of growth of Mycobacterium leprae.BALB/c mice were inoculated in the right hind footpad with 5 x 10(3) organisms and sacrificed in pairs at 86 to 173 days after inoculation. Tissue samples were prepared for electron microscopy by standa...
