The first step towards figuring out the cause of echinococcosis occurred during the 17th century when Francesco Redi illustrated that the hydatid cysts of echinococcosis were of "animal" origin. Then, in 1766, Pierre Simon Pallas predicted that these hydatid cysts found in infected humans were larval stages of tapeworms. [51] [52]
Echinococcus granulosus, also called the hydatid worm or dog tapeworm, is a cyclophyllid cestode that dwells in the small intestine of canids as an adult, but which has important intermediate hosts such as livestock and humans, where it causes cystic echinococcosis, also known as hydatid disease.
It penetrates the intestinal wall and is carried by bloodstream to liver, lung, brain, or another organ. It settles there and turns into a bladder-like structure called hydatid cyst. From the inner lining of its wall, protoscoleces (i.e. scoleces with invaginated tissue layers) bud and protrude into the fluid filling the cyst.
eggs passed in feces, ingested by humans or intermediate host; onchosphere penetrates intestinal wall, carried via blood vessels to lodge in organs; hydatid cysts develop in liver, lungs, brain, heart; protoscolices (hydatid sand) ingested by definitive host; ingested protoscolices attach to small intestine and develops into adult worm
Alveolar hydatid disease (AHD) is a form of echinococcosis, or a disease that originates from a parasitic flatworm. AHD is caused by an infection of the flatworm species Echinococcus multilocularis . [ 1 ]
Changes in the eye can help predict other health concerns in the body, such as diabetes and high blood pressure. A new study has identified a set of 29 vascular health indicators on the retina ...
An ocular manifestation of a systemic disease is an eye condition that directly or indirectly results from a disease process in another part of the body. There are many diseases known to cause ocular or visual changes.
Woodruff, who has studied the effect of some chemicals found in plastics on human health, reproduction, and development for two decades, first started looking into microplastics in 2021.
