Synchytrium Endobioticum
''Synchytrium endobioticum'' is a chytrid fungus that causes the potato wart disease, or black scab. It also infects some other plants of the genus ''Solanum'', though potato is the only cultivated host (biology), host. Systematics Traditionally, ''Synchytrium endobioticum'' has been placed to the subgenus ''Mesochytrium'', but it has been suggested that, on the basis of the mode of germination, it should be transferred to the subgenus ''Microsynchytrium''. It was first identified and studied by Vera Charles. The New Zealand scientist Kathleen Maisey Curtis also studied ''Synchytrium endobioticum'' for her doctoral thesis that, in 1919, resulted in her being recognised as producing groundbreaking research on the organism's pathology. At least 18 pathotypes of the fungus exist, most of which have quite limited ranges in Central Europe. The most widely distributed is pathotype 1. Morphology Like some other Chytridiales, ''Synchytrium endobioticum'' develops no mycelium. The fung ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meiotic
Meiosis () is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, the sperm or egg cells. It involves two rounds of division that ultimately result in four cells, each with only one copy of each chromosome (haploid). Additionally, prior to the division, genetic material from the paternal and maternal copies of each chromosome is crossed over, creating new combinations of code on each chromosome. Later on, during fertilisation, the haploid cells produced by meiosis from a male and a female will fuse to create a zygote, a cell with two copies of each chromosome. Errors in meiosis resulting in aneuploidy (an abnormal number of chromosomes) are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities. In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells, each with half the number of chromosomes as the original parent cell. The t ...

Chytridiomycota
Chytridiomycota are a division of zoosporic organisms in the kingdom Fungi, informally known as chytrids. The name is derived from the Ancient Greek ('), meaning "little pot", describing the structure containing unreleased zoospores. Chytrids are one of the earliest diverging fungal lineages, and their membership in kingdom Fungi is demonstrated with chitin cell walls, a posterior whiplash flagellum, absorptive nutrition, use of glycogen as an energy storage compound, and synthesis of lysine by the -amino adipic acid (AAA) pathway. Chytrids are saprobic, degrading refractory materials such as chitin and keratin, and sometimes act as parasites. There has been a significant increase in the research of chytrids since the discovery of '' Batrachochytrium dendrobatidis'', the causal agent of chytridiomycosis. Classification Species of Chytridiomycota have traditionally been delineated and classified based on development, morphology, substrate, and method of zoospore disch ...

Prince Edward Island
Prince Edward Island is an island Provinces and territories of Canada, province of Canada. While it is the smallest province by land area and population, it is the most densely populated. The island has several nicknames: "Garden of the Gulf", "Birthplace of Canadian Confederation, Confederation" and "Cradle of Confederation". Its capital and largest city is Charlottetown. It is one of the three Maritime provinces and one of the four Atlantic provinces. Part of the traditional lands of the Mi'kmaq, it was colonized by the French in 1604 as part of the colony of Acadia. The island, known as Isle St-Jean (St. John's Island), was ceded to the British at the conclusion of the Seven Years' War in 1763 and became part of the colony of Nova Scotia. In 1769, St. John's Island became its own British colony and its name was changed to Prince Edward Island (PEI) in 1798. PEI hosted the Charlottetown Conference in 1864 to discuss a Maritime Union, union of the Maritime provinces; however, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Health Security And Bioterrorism Preparedness Response Act
Signed into effect on 12 June 2002, the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 (PHSBPRA) was signed by the President, the Department of Health and Human Services ( DHHS) and the U.S. Department of Agriculture (USDA). It established procedures for preparation for bioterrorism and public health emergencies. It also created the National Disaster Medical System, through which teams of health professionals, such as physicians, pharmacists, paramedics, and nurses, volunteer in emergency situations. A component of the new rules include security risk assessment of individuals who have access to the select agents and toxins. It is intended to establish new rules for registering the possession, use, and transfer of specific toxins and agents that could endanger the safety and health of people, animals, and plants. Any person who meets the criteria of a "restricted person" as defined in the USA PATRIOT Act of 2001, must not be afforded access to thes ...

Pathogens
In biology, a pathogen (, "suffering", "passion" and , "producer of"), in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. The term ''pathogen'' came into use in the 1880s. Typically, the term ''pathogen'' is used to describe an ''infectious'' microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus. Small animals, such as helminths and insects, can also cause or transmit disease. However, these animals are usually referred to as parasites rather than pathogens. The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology, while parasitology refers to the scientific study of parasites and the organisms that host them. There are several pathways through which pathogens can invade a host. The principal pathways have different episodic time frames, but soil has the longest or most pers ...

Bioterrorism
Bioterrorism is terrorism involving the intentional release or dissemination of biological agents. These agents include bacteria, viruses, insects, fungi, and/or their toxins, and may be in a naturally occurring or a human-modified form, in much the same way as in biological warfare. Further, modern agribusiness is vulnerable to anti-agricultural attacks by terrorists, and such attacks can seriously damage economy as well as consumer confidence. The latter destructive activity is called agrobioterrorism and is a subtype of agro-terrorism. Definition Bioterrorism agents are typically found in nature, but could be mutated or altered to increase their ability to cause disease, make them resistant to current medicines, or to increase their ability to be spread into the environment. Biological agents can be spread through the air, water, or in food. Biological agents are attractive to terrorists because they are extremely difficult to detect and do not cause illness for severa ...

Middle East
The Middle East (term originally coined in English language) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage by the United Kingdom and western European nations in the early 20th century as a replacement of the term Near East (both were in contrast to the Far East). The term "Middle East" has led to some confusion over its changing definitions. Since the late 20th century, it has been criticized as being too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus. It also includes all of Egypt (not just the Sinai Peninsula, Sinai) and all of Turkey (including East Thrace). Most Middle Eastern countries (13 out of 18) are part of the Arab world.

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. .
