Liver flukes infect all grazing animals and infect humans when they eat raw or undercooked fish. Like other flukes, the liver flukes need intermediate hosts and as a result, the transmission from animals to humans happens in three phases. The first phase is the infection of the snail (the first intermediate host) via feces.
As of 2010, the IUCN Red List, which incorporates the Global Amphibian Assessment and subsequent updates, lists 650 amphibian species as "Critically Endangered", and 35 as "Extinct". [4] Despite the high risk this group faces, recent evidence suggests the public is growing largely indifferent to this and other environmental problems, posing ...

Protozoan infections are responsible for diseases that affect many different types of organisms, including plants, animals, and some marine life. Many of the most prevalent and deadly human diseases are caused by a protozoan infection, including African sleeping sickness, amoebic dysentery, and malaria.
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane , such as modern reptiles , birds and mammals ).
The majority of Cryptococcus species live in the soil and do not cause disease in humans. Cryptococcus neoformans is the major human and animal pathogen. Papiliotrema laurentii and Naganishia albida, both formerly referred to Cryptococcus, have been known to occasionally cause moderate-to-severe disease in human patients with compromised immunity.
In both the show and the video game it’s based on, a frog — or a human contestant — attempt to navigate the many perils of modern life. Navigating an obstacle course of lily pads and ...
