3.  Worldwide where Dogs are found

4.  Adult  Female: 6.5-15 cm  Male: 4-6 cm long  Three lips  Prominent cervical alae  Egg  Brownish color and almost spherical (85µm x 75µm)

5.  Definitive: Dogs  Paratenic & Accidental: Humans and other usually small mammals

7.  In dogs usually asymptomatic  In puppies  Noisey breathing  Vomiting  Diarrhea  Pot belly  May cause death in heavy infections  In Humans usually asymptomatic  Abdominal pain  Decreased apetite  Fever  Hives  Restlessness  Various other symptoms depend on what organ the larvae infect

8.  Caused by larvae that have migrated to the retina of the eye  Inflammation  Formation of scars  Detachment of retina  Partial to full vision loss

9.  Caused from Larvae wondering throughout various organs of the body (brain, lungs, liver(most common), heart,muscle)  Depend on organ that is infected Fever Pulmonary symptoms Hepatospleenmegaly Eosinophilia Asthma

10.  Dogs  Assume all puppies are infected  Check for eggs in multiple stool samples (because eggs are not shed at all times)  Humans  ELISA – identifies certain antibodies in the blood Can distinguish between A. lumbricoides & T. canis  Clinical signs  History of exposure to puppies

11.  Antiparasitc drugs o Albendazole (drug of choice) o Mebendacole o usually with Anti-inflammatory  OLM no known treatment  Steroids have been used but are unsure if it is effective or not
