Last year, Biogen took one price increase for its multiple sclerosis drugs in January, Abrahams noted, and the company is likely to do the same this year, given the .
Tapeworm Causes. Six types of tapeworms are known to infect people. They are usually identified by the animals they come from -- for example, Taenia saginata from beef, Taenia solium from pork, and Diphyllobothrium latum from fish. Tapeworms have a three-stage lifecycle: egg, an immature stage called a larva, and an adult stage at which the worm can produce more eggs.
Tapeworms get into the body when a person eats or drinks something that's infected with a worm or its eggs. Once inside the body, the tapeworm head attaches to the inner wall of the intestines. The tapeworm feeds off the food that the host is digesting. It uses this nutrition to grow. Tapeworms are made up of segments, and they get longer by growing new segments. Each segment can reproduce by making thousands of eggs. Since tapeworms can have more than 3,000 segments, that's a lot of opportunity to spread. New segments grow at the head of the tapeworm, pushing older segments to the end of the line, where they break off.
