Acinetobacter

Acinetobacter

The Acinetobacter are a group of bacteria from the genus Gammaproteobacteria, all of which are gram-negative and encompass many different life forms. Acinetobacter is one of the best-known aerobic bacteria and is best known as a multidrug-resistant hospital germ. For immunodeficient patients, an infection can be fatal

Acinetobacter baumannii

Acinetobacter baumannii

As Acinetobacter baumannii a human pathogenic dangerous hospital germ is called. The bacterium predominantly affects humans, in whom a defense weakness exists. What is Acinetobacter baumannii? Acinetobacter baumannii bacteria are aerobic short-rod bacteria. © Robert Kneschke - stock.adobe.com Acinetobacter baumannii is a Gram-negative short-rod bacterium from the group Acinetobacter.

Actinobacillus

Actinobacillus

The bacterial genus Actinobacillus belongs to the Department of Proteobacteria and the family of Pasteurellaceae. There is a name affinity with the actinomycetes, since the genus is often involved as an opportunistic pathogen in actinomycoses. What is Actinobacillus? Bacterial species of the genus Actinobacillus have a slender and partially oval shape

Actinomyces

Actinomyces

Actinomyces are rod-shaped bacteria of the order Actinomycetales, which are also called ray fungi due to their characteristic appearance under the microscope. The bacteria preferentially colonize vertebrates and appear either parasitic or commensal. An infection leads to an actinomycosis of the oral cavity and partly lung or liver

apicomplexa

apicomplexa

Apicomplexa, also called sporozoa, are single-celled parasites with cell nucleus whose multiplication takes place in the alternation between asexual schizogony and the sporozoites produced by sexual fusion of gametes. As a rule, the change is associated with apicomplexa typical host change. The most well-known representatives of the apicomplexa belonging to the Eukaryoten are Plasmodien (exciters of the malaria) and Toxoplasma gondii (exciters of the Toxoplasmose)

archaea

archaea

The Archaea or Urbakterien are cellular life forms in addition to the other groups of bacteria and eukaryotes. In the late 1970s, the archees were described by the microbiologists Carl Woese and George Fox and classified as a separate group. What are archaea? Archaea are unicellular organisms that possess DNA (deoxyribonucleic acid) in the form of a circular chromosome

ascomycota

ascomycota

Ascomycota is another name for ascomycetes, which occur in very different manifestations. They are found in almost all habitats and their range varies from very useful (for the production of food such as bread, beer, wine, etc.) to valuable and tasty edible mushrooms (such as truffles and morels) to the cause of serious infectious diseases, for example, by Candida or Aspergillus species

Aspergillus

Aspergillus

The term Aspergillus summarizes about 350 species of mold that are characterized by a spore carrier reminiscent of Aspergillus. Molds of this type often form so-called mushroom turf with different colorations of milky white over greenish-gray, red, brown and yellowish to black. A few of the world's most common and almost omnipresent species of Aspergillus produce mycotoxins, which are very toxic to humans, or they trigger so-called aspergillosis

Aspergillus fumigatus

Aspergillus fumigatus

Aspergillus fumigatus is a mold called Aspergillus genus. It is considered a high health risk for people with immunodeficiency. What is Aspergillus fumigatus? The mold fungus Aspergillus fumigatus comes from the genus Aspergillus (watering can mold). The Latin name "fumigatus" is due to the smoke green mushroom coloring

Bacillaceae

Bacillaceae

The Bacillaceae are gram-positive bacteria from the group of bacillales. A known pathogen of this family is Bacillus anthracis, the causative agent of anthrax. What are Bacillaceae? Bacillaceae is a family within the bacterial species. They belong to the order Bacilliales. Within the family of Bacillaceae more than 50 different genera are known

Bacillales

Bacillales

Bacillales are an order from the Bacilli bacterial class containing families such as Alicyclobacillaceae, Bacillaceae, Listeriaceae and Paenibacillaceae. Bacteria of the order show gram-positive properties and often form endospores, especially under unfavorable conditions. While some are used as probiotics, others are opportunistic or obligate pathogens

Bacillus anthracis

Bacillus anthracis

Bacillus anthracis causes the well-known animal anthrax anthrax and was discovered in 1849 by Aloys Pollender. It was first propagated in the laboratory in 1876 and identified by Robert Koch as an anthrax pathogen. The first vaccine against infectious lethal disease was developed in 1881 by Louis Pasteur and successfully tested on a large flock of sheep

bacilli

bacilli

Bacteria are also called rod bacteria. The bacilli include bacteria such as Escherichia coli or Salmonella. What are bacilli? Escherichia coli is known in the human intestinal flora as a vitamin supplier, especially vitamin K's. The bacterium usually does not cause any diseases. Click to enlarge

Bacillus cereus

Bacillus cereus

Bacillus cereus is a gram-positive rod-shaped bacterium of the genus Bacillus and of the order Bacillales, which belongs to the class Bacilli and family Bacillaceae of the division Firmicutes. The bacterium is ubiquitous in the environment and is taken up with raw materials or food in the form of germs

Bacillus stearothermophilus

Bacillus stearothermophilus

Bacillus stearothermophilus is an apathogenic and rod-shaped species of bacteria of the family Bacillaceae and division Firmicutes. The bacterial species is one of the so-called spore formers, thus forming resistant endospores under unfavorable conditions. For humans, the bacterial species is especially important as a test germ, for example for the control of thermal devices for sterilization

Bacillus subtilis

Bacillus subtilis

Bacillus subtilis is a single-celled organism that occurs naturally in the uppermost layer of the earth. The pharmacy uses Bacillus subtilis, among others, in antibiotics, for example for the treatment of gonorrhea. What is Bacillus subtilis? Bacillus subtilis is also known as hay bacillus. Christian Gottfried Ehrenberg described the unicellular already in 1835

Bacteroides

Bacteroides

Bacteroides form a genus of obligate anaerobically living, undefiled - and thus usually immobile - bacteria that are part of the natural bacterial flora in the digestive tract of humans and have important functions in certain metabolic processes. Particularly high is the proportion of Gram-negative bacteria in the colon

bacteriophages

bacteriophages

Bacteriophages are viruses that infect and multiply bacteria. For every bacterium there is also a specific bacteriophage. Bacteriophages are used in medicine and genetic engineering. What are bacteriophages? Bacteriophages are a group of viruses that infect bacteria and archaea. They continue to multiply under the destruction of the bacterium

Bacteria occur in and in humans in a large variety. While some bacteria promote good health, other bacteria can be detrimental to your health. Bacteria should not be confused with bacilli, a rod-shaped genus of motile bacteria. What are bacteria? Schematic representation of the components and composition of a bacterium
