1 E. cuniculi are carried in the blood to other parts of the body, particularly neural tissue. 2  Spores from infected urine can remain in the environment for a month. 3  The parasites can infect and be shed by many other animals but seldom cause clinical disease in other animals.
Most annual flowers will die when fall brings frost. Marigolds, zinnias, petunias, delphinium and many other common flowering plants are examples of plants that frost will kill. In more northerly climate zones, it's difficult to get anything to bloom in the harsh winter months.
Marigolds flower better and look more attractive if you cut off the dead flowers continually from the time the begin to bloom until they stop flowering in fall. Cut back the dead flower heads as the blooms fade, removing them above the topmost set of leaves on the stem.
