Environmentally resistant oocysts and sporocysts are released into the environment by the definitive hosts' (opossums) feces. Numerous mammals primarily including armadillos, raccoons, sea otters, skunks, and cats serve as intermediate hosts for S. neurona and ingest many sporocysts.
Response to treatment is often variable, and treatment may be expensive. Recently, antiprotozoal treatments that kill the parasite and clear the infection have shown promise. The inflammatory component is thought responsible for the symptoms of EPM; anti-inflammatory drugs that target the IL-6 pathway have been particularly effective at ...

Treatment is routine and effective. Diagnosis is made by low-powered microscopic examination of the feces, which is generally replete with oocysts. Readily available drugs eliminate the protozoa or reduce them enough that the animal's immune system can clear the infection.
Instead, the larvae continue to migrate unpredictably unable to develop into adults, so eggs are seldom found in diagnostic tests or human feces. [1] [9] This also means the number of worms present in humans is a reflection of the number of third-stage larvae ingested. [citation needed]
Human alveolar echinococcosis is characterized by a lengthy incubation period of 5 to 15 years in immunocompetent individuals. The progression of disease is potentiated in immunocompromised patients. Following the ingestion of the eggs of E. multilocularis, the metacestode (larval) stage of the parasite typically embeds in the liver.
Mange (/ ˈ m eɪ n dʒ /) is a type of skin disease caused by parasitic mites. [1] Because various species of mites also infect plants, birds and reptiles, the term "mange", or colloquially "the mange", suggesting poor condition of the skin and fur due to the infection, is sometimes reserved for pathological mite-infestation of nonhuman mammals.
The primary antidote to brodifacoum poisoning is immediate administration of vitamin K 1 (dosage for humans: initially slow intravenous injections of 10–25 mg repeated at 3–6 hours until normalisation of the prothrombin time; then 10 mg orally four times daily as a "maintenance dose"). It is an extremely effective antidote, provided the ...
