Gapeworms are common in young, domesticated chickens and turkeys. When the female gapeworm lays her eggs in the trachea of an infected bird, the eggs are coughed up, swallowed, then defecated.hen birds consume the eggs found in the feces of an intermediate host such as earthworms, snails (Planorbarius corneus, Bithynia tentaculata and others), or slugs, they become infected with the parasite.

Maguire and colleagues reported that Avastin delivered monthly cost an average of $595 and Lucentis cost $23,400. If the drugs were taken only as needed, rather than on a monthly basis, the cost dropped for both drugs, but Avastin was still the bargain choice: $385 for the year of treatment compared with $13,800.f the drugs were taken only as needed, rather than on a monthly basis, the cost dropped for both drugs, but Avastin was still the bargain choice: $385 for the year of treatment compared with $13,800.
Costs of Cancer. Newly approved cancer drugs cost an average of $10,000 per month, with some therapies topping $30,000 per month, according to ASCO, which discussed the costs of cancer care at a recent meeting. Just a decade ago, the average cost per month of new drugs was about $4,500. Patients typically pay 20 to 30 percent out of pocket for drugs, so an average year's worth of new drugs would cost $24,000 to $36,000 in addition to health insurance premiums.
