Bacillus Anthracis
_BACILLUS ANTHRACIS_ is the etiologic agent of anthrax —a common disease of livestock and, occasionally, of humans—and the only obligate pathogen within the genus _ Bacillus
Bacillus
_. _B. anthracis_ is a Gram-positive , endospore -forming, rod-shaped bacterium , with a width of 1.0–1.2 µm and a length of 3–5 µm. It can be grown in an ordinary nutrient medium under aerobic or anaerobic conditions. _ B. anthracis_ belongs to the _B. cereus_ group of strains. _ Structure of B. anthracis_ It is one of few bacteria known to synthesize a protein capsule (poly-D-gamma-glutamic acid). Like _ Bordetella pertussis _, it forms a calmodulin -dependent adenylate cyclase exotoxin known as Anthrax edema factor , along with anthrax lethal factor . It bears close genotypical and phenotypical resemblance to _ Bacillus
Bacillus
cereus _ and _ Bacillus

Taxonomy (biology)
TAXONOMY (from Ancient Greek τάξις _(taxis )_, meaning 'arrangement', and -νομία _(-nomia)_, meaning 'method ') is the science of defining and naming groups of biological organisms on the basis of shared characteristics. Organisms are grouped together into taxa (singular: taxon) and these groups are given a taxonomic rank ; groups of a given rank can be aggregated to form a super group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are kingdom, phylum, class, order, family, genus and species. The Swedish botanist Carl Linnaeus is regarded as the father of taxonomy, as he developed a system known as Linnaean taxonomy for categorization of organisms and binomial nomenclature for naming organisms

Firmicutes
The FIRMICUTES ( Latin
Latin
: _firmus_, strong, and _cutis_, skin, referring to the cell wall) are a phylum of bacteria , most of which have Gram-positive cell wall structure. A few, however, such as _ Megasphaera _, _ Pectinatus _, _ Selenomonas _ and _ Zymophilus _, have a porous pseudo-outer membrane that causes them to stain Gram-negative . Scientists once classified the Firmicutes
Firmicutes
to include all Gram-positive bacteria, but have recently defined them to be of a core group of related forms called the low-G+C group, in contrast to the Actinobacteria . They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). Many Firmicutes

Binomial Nomenclature
BINOMIAL NOMENCLATURE (also called BINOMINAL NOMENCLATURE or BINARY NOMENCLATURE) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms , although they can be based on words from other languages. Such a name is called a BINOMIAL NAME (which may be shortened to just "binomial"), a BINOMEN, BINOMINAL NAME or a SCIENTIFIC NAME; more informally it is also called a LATIN NAME. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus _ Homo _ and within this genus to the species _ Homo sapiens _. The _formal_ introduction of this system of naming species is credited to Carl Linnaeus , effectively beginning with his work _ Species Plantarum _ in 1753

Etiology
ETIOLOGY (/iːtiˈɒlədʒi/ ; alternatively AETIOLOGY or æTIOLOGY) is the study of causation , or origination. The word is derived from the Greek αἰτιολογία, _aitiologia_, "giving a reason for" (αἰτία, _aitia_, "cause"; and -λογία, _-logia_). The word is most commonly used in medical and philosophical theories, where it is used to refer to the study of why things occur, or even the reasons behind the way that things act, and is used in philosophy , physics , psychology , government , geography , spatial analysis , medicine , theology , and biology in reference to the causes of various phenomena . An etiological myth is a myth intended to explain a name or create a mythic history for a place or family, an origin story

Anthrax
ANTHRAX is an infection caused by the bacterium _ Bacillus
Bacillus
anthracis _. It can occur in four forms: skin, inhalation, intestinal, and injection. Symptoms begin between one day and two months after the infection is contracted. The skin form presents with a small blister with surrounding swelling that often turns into a painless ulcer with a black center. The inhalation form presents with fever, chest pain, and shortness of breath . The intestinal form presents with nausea, vomiting, diarrhea, or abdominal pain. The injection form presents with fever and an abscess at the site of drug injection . Anthrax
Anthrax
is spread by contact with the spores of the bacteria , which are often from infectious animal products. Contact is by breathing, eating, or through an area of broken skin. It does not typically spread directly between people

Pathogen
In biology , a PATHOGEN (Greek : πάθος _pathos_ "suffering, passion" and -γενής _-genēs_ "producer of") in the oldest and broadest sense is anything that can produce disease ; the term came into use in the 1880s. Typically the term is used to describe an infectious agent such as a virus , bacterium , protozoa , prion , a fungus , or other micro-organism. There are several substrates including _pathways_ where the pathogens can invade a host. The principal pathways have different episodic time frames, but soil contamination has the longest or most persistent potential for harboring a pathogen. Diseases caused by organisms in humans are known as pathogenic diseases

Gram-positive
GRAM-POSITIVE BACTERIA are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their cell wall. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through a microscope. This is because the thick peptidoglycan layer in the bacterial cell wall retains the stain after it is washed away from the rest of the sample, in the decolorization stage of the test. Gram-negative bacteria cannot retain the violet stain after the decolorization step; alcohol used in this stage degrades the outer membrane of gram-negative cells making the cell wall more porous and incapable of retaining the crystal violet stain

Endospore
An ENDOSPORE is a dormant , tough, and non-reproductive structure produced by certain bacteria from the Firmicute phylum. The name "endospore" is suggestive of a spore or seed-like form (_endo_ means within), but it is not a true spore (i.e., not an offspring). It is a stripped-down, dormant form to which the bacterium can reduce itself. Endospore
Endospore
formation is usually triggered by a lack of nutrients, and usually occurs in gram-positive bacteria . In endospore formation, the bacterium divides within its cell wall. One side then engulfs the other. Endospores enable bacteria to lie dormant for extended periods, even centuries. Revival of spores millions of years old has been claimed. When the environment becomes more favorable, the endospore can reactivate itself to the vegetative state. Most types of bacteria cannot change to the endospore form
