Tapeworms: These are segmented flat worms spread through a vector, such as
the common flea or infected meat. There are several types of tapeworms that
infect humans and animals. These worms are often visible to the naked eye
due to the segments passed in the feces.
Echinococcus is a tape worm that has dogs as the direct host, although it
causes few problems in them. Dogs (and rarely cats) get the worm by eating
infected meat (such as sheep parts which contain cysts. The sheep get the
disease through eating contaminated water and vegetation. This disease is of
concern due to the severity of disease in people. People contract the
disease by direct contact with a dog shedding eggs (especially children),
eating undercooked meat, or contaminated water or vegetables. The worm
causes hydatid disease, in which the larvae migrate through the blood into
the liver, lungs, and other body parts. The worms form large cysts which
cause severe inflammation, even death. Luckily, infection in the US is rare
(it is more common in Mexico). Control is through hygiene and cooking of
meat. Dogs should be prevented from scavenging and eating offal. If eggs are
found on a fecal sample, or if exposure is known, a drug called praziquantel
can be given. This drug is ineffective on roundworms. It does not prevent
re-infection.

Hydatid disease
        a.. Due to infection with the helminth Ecchinococcus granulosa
        b.. Adult worm is found normally in the dog and sheep intestine
        c.. Man is an accidental intermediate host
        d.. Infection seen in Mediterranean areas, Australia and South
America
        e.. Liver is the commonest organ involved
        f.. Cysts are unilocular, can be up to 20 cm in diameter and may be
multiple
        g.. Daughter cysts may develop
        h.. 70% develop in the right lobe of the liver
        i.. Lung, brain and bone can also be infected
        j.. Pathologically hydatid liver cyst has three distinct layers:
          a.. Ectocyst - fibrous advential layer due to host response
          b.. Middle layer - laminated membrane of proteinaceous material
          c.. Endocyst - inner germinal layer from which the scolices may be
detached

Hydatid disease is caused by Ecchinococcus granulosus.
The adult parasite (0.5-1 cm) resides in the intestines of
animals such as dogs, foxes, wolves, and jackals. The ova,
which are resistant to many environmental conditions, are
excreted in the feces and ingested by the intermediate hosts,
herbivores and humans. The ova hatch in the small intestine,
where the parasites penetrate the mucosal wall and reach the
liver via the portal vein. They are trapped in the sinusoids;
therefore, the liver is the most frequently involved organ
(70%).3 The larvae which pass through this first filter, reach
the lung via the right heart; the lung is the second most
frequently involved site (10-15%). The larvae, which pass
through this second filter cause hydatid disease in other organs
(5-15%).3 In a large series from Greece, the frequency
of extrahepatic and extrapulmonary hydatidosis was 9%.4 In
addition to systemic dissemination via the portal vein, there
are preliminary data on the possibility of dissemination
through lymphatic channels, whereas the role of the bronchial
route is dubious.

Danach verzichtete er auf weitere Experimente.
Dio creò l' uomo perché la scimmia l' aveva deluso.
Dopo però rinunciò ad altri sperimenti.
