We find that it is unlikely that this obligate symbiotic relationship relies on a single process or pathway, but rather on more complex interactions that likely vary over
the life cycle of the parasite,» the researchers conclude.
Amphibious and aquatic snails like this one are a weak link in
the life cycle of parasites that cause snail fever.
When the adult worms begin to reproduce, eggs will pass into the cat's stool, thus completing
the life cycle of the parasite.
When these worms begin to reproduce, new eggs will pass in the cat's stool, and
the life cycle of the parasite is completed.
When these worms begin to reproduce, new eggs will pass in the dog's stool, and
the life cycle of the parasite is completed.
This should be performed at least two months in a row in order to kill
all life cycles of parasites.
``... cats are the most important species in
the life cycle of the parasite responsible for toxoplasmosis, and in 3 separate studies, most feral cats (62 percent to 80 percent) tested positive for toxoplasmosis.»
Foxes, coyotes, and the wild rodents upon which they prey are important in
the life cycle of this parasite.
The life cycle of this parasite almost ensures that a puppy or a kitten will be exposed.
Treatment is commonly repeated in 3 weeks and 3 months due to
the life cycle of this parasite.
Nematodes generally require two treatments spaced 2 to 3 weeks apart, depending upon
the life cycle of the parasite.
Due to
the life cycle of the parasite the preventatives are given monthly.
Rotate pastures by allowing other livestock, such as sheep or cattle, to graze them, thereby interrupting
the life cycles of parasites.
The life cycle of parasites initially involves mild bruising and reddened skin and thereafter crusts.
Some of these treatments may be continued or repeated over several weeks or months to coincide with
the life cycle of the parasite determined to be at fault.
