2 most important forms are cystic and alveolar caused by E. granulosus and E. multilocularis
Humans are accidental immediate hosts by ingesting parasitic eggs from contaminated food, soil, water, or direct contact with definitive hosts
Usual intermediate hosts-sheep, goat, swine, cattle, rodents and camel
Definitive hosts-dogs, cats, fox, and wolves
Ingested eggs then hatch, penetrate intestinal mucosa, and spread hematogenously to final destination to form cysts
Echinococcosis
Neurocysticercosis
Cryptococcosis
Pyogenic abscess
Hepatocellular carcinoma
Aerobic: Escherichia coli, Klebsiella, Pseudomonas
Hepatic abscess
Anaerobic: Enterococcus, bacteroides, anaerobic streptococci
