Plasmodium vivax
Plasmodium vivax is a protozoal parasite and a human pathogen. This parasite is the most frequent and widely distributed cause of recurring (Benign tertian) malaria, "P. vivax" is one of the five species of malaria parasites that commonly infect humans. Although it is less virulent than "Plasmodium falciparum", the deadliest of the five human malaria parasites, "P. vivax" malaria infections can lead to severe disease and death, often due to splenomegaly (a pathologically enlarged spleen). "P. vivax" is carried by the female "Anopheles" mosquito; the males do not bite.
Bat
White nose syndrome is a condition associated with the deaths of millions of bats in the Eastern United States and Canada. The disease is named after a white fungus, "Pseudogymnoascus destructans", found growing on the muzzles, ears, and wings of afflicted bats. The fungus is mostly spread from bat to bat, and causes the disease. The fungus was first discovered in central New York State in 2006 and spread quickly to the entire Eastern US north of Florida; mortality rates of 90–100% have been observed in most affected caves. New England and the mid-Atlantic states have, since 2006, witnessed entire species completely extirpated and others with numbers that have gone from the hundreds of thousands, even millions, to a few hundred or less. Nova Scotia, Quebec, Ontario, and New Brunswick have witnessed identical die offs, with the Canadian government making preparations to protect all remaining bat populations in its territory. Scientific evidence suggests that longer winters where the fungus has a longer period to infect bats result in greater mortality. In 2014, the infection crossed the Mississippi River, and in 2017, it was found on bats in Texas.
