Ovulation occurs at the end of metestrus. The disease produces massive die off in adult mice and amputation of the limbs (ectromelia) in surviving animals. The eggs are particularly resistant and survive for a long time in the environment. Subcutaneous injectionsSubcutaneous injections are usually made into the loose skin over the neck or flank using a fine gauge needle.
