Army Ants | | | | | | There are over 200 known species of army ant‚ divided into New World and Old World types. All are members of the true ant family Formicidae. New World army ants belong to the subfamily Ecitoninae. This subfamily is further broken into two groups‚ Cheliomyrmex and the Ecitonini. The Ecitonini group contains three genera‚ Neivamyrmex‚ Nomamyrmex‚ Labidus‚ and Eciton‚ the genus after which the group is named (Brady‚ 2003‚ Tree of Life). The most predominant species

Cereal rusts became a problem when the first cereal crops were grown in the fertile cresent. However it took two Italian scientists‚ Fontana and Tozzeti to give us the first detailed description of stem rust fungus in 1767. Thirty years later in 1797 it was given the name Puccinia graminis. Puccinia fungal diseases are the most destructive disease of cereal production. They occur all over the world. Stem rust is a fungal disease caused by the pathogen Puccinia graminis and is a significant disease

disease also called coccidioidomycosis or (CM) due to a fungus called Coccidioides immitis. About 40% of people infected with this fungus develop symptoms. Most often they have an influenza-like illness with fever‚ cough‚ headaches‚ rash‚ and myalgias. Usually‚ those people with symptoms‚ 8% have severe lung disease requiring hospitalization and about 7% develop disseminated infection throughout the body. Valley fever is a lung infection.

yeast and an obligate aerobe that lives in the environment throughout the world both in plants and animals. It is often found in bird excrement. People can get infected with C. neoformans through breathing in the microscopic fungus‚ although most people who get exposed to the fungus never get sick from it. Most cases of this infection occur in people who have weakened immune system‚ mainly those who have HIV/AIDS. In 1894‚ Busse‚ a pathologist‚ first described the yeast in a paper he presented to the

infection that only effects Elm trees. It is caused by Ophiostoma ulmi‚ which is a species of fungus that makes the tree’s leaves and branches wilt and die (D’Arcy 1). Dutch Elm Disease had a great impact on the population of Elm trees in North America and Europe. This issue was fixed in 2001 when scientist created a genetically modified Elm tree that could resist the fungus (Daily Science 1). To resist fungus‚ plants must be modified by adding bacteria encoding enzymes like chitinase or glucanase to

People who do not bathe regularly are more susceptible to fungus infections such as jock itch‚ athlete’s feet or toenail fungus infections. A lack of oral hygiene can cause fungus infections such as oral thrush. Those who fail to wash their hands regularly are more prone to getting viruses or bacterial infections from others.
