Pathogen

Of the approximately 1,800 species of snakes that exist on earth, only a little more than a fifth are poisonous. And these are not the giant snakes, but the medium and small species. The large snakes have only ordinary, solid teeth and

The Trichophyton mentagrophytes is one of the dermatophytes, i.e. fungi that mainly affect the skin, but also skin appendages such as nails and hair. There are also about 20 other types of trichophytes. The diseases affecting the dermatophytes

Molds are more common in everyday life. For example, they can be on fruit and vegetables or on ceilings and walls. Because the microorganisms can be harmful to health, it is important to remove them quickly.

Pork tapeworm (Taenia solium) is a parasite that is transmitted to humans through the consumption of raw pork. For Taenia solium, humans are final hosts, whereas pigs are only intermediate hosts.

Serratia or Serratia, as they are also called, belong to the family of intestinal bacteria (enterobacteria). The majority of pathogens are harmless to people with an intact immune system. They can be found in hospitals and infant wards

Four different families of gram-negative, extremely thin and long, helical bacteria that can actively move make up the group of spirochetes. They occur in soils and bodies of water and as parasites or commensals in the digestive tract

Roundworms are parasites. They enter the human body in order to feed on it. It is not your goal to kill the host concerned. However, they can still cause greater damage and should therefore absolutely

Spirillae are a genus of bacteria in the Spirillaceae family. They were discovered in 1832 by the natural scientist Christian G. Ehrenberg.

One type of bacteria has made a name for itself like no other type of bacteria in the treatment of diseases and resistance to antibiotics: Staphylococcus aureus. This germ is in most people for a lifetime

Staphylococcus capitis belong to the superordinate bacterial group of cocci and, as communal bacteria, colonize human skin and the mucous membranes of the nose. For healthy people, contact with Staphylococcus capitis is no longer tragic. Immune speed

Staphylococci (Latin: Staphylococcus) are bacteria that belong to the subgroup of cocci. They look round to grape-like and are immobile. They were first identified in 1884 by Friedrich Julius Rosenbach.

Staphylococcus epidermidis is a gram-positive bacterium that colonizes human skin and mucous membranes as a saprophage. The bacterium is not pathogenic for people with an intact immune system. However, it can affect polymeric plastic surfaces

The bacterium Streptococcus mitis belongs to the Viridans streptococci. The viridans streptococci occur predominantly in the oropharynx.

Mosquitoes are common all over the world. Most people already have experience with the insects. Most of the time, they only leave swelling and itching, but they can also transmit pathogens. That is why in particular

The Streptococcus mutans is a gram-positive, immobile, facultatively anaerobic pathogen of the genus streptococci. These are spherical bacteria that usually accumulate in chain form. S. mutans comes as a commensal in the mouth

Bacteria of the species Streptococcus salivarius belong to the genus Streptococci, to the Firmicutes division, the class Bacilli and the order of lactic acid bacteria. Physiologically, they occur in the oral flora. Especially for immunocompromised people

Streptococcus sanguis are bacteria of the genus Streptococci, which belong to the group of Viridans streptococci and are a natural component of the human oral flora. The bacteria prevent the oral flora from being colonized by pathogenic bacteria

Streptococci colonize the mucous membranes of healthy people and are considered harmless there. However, they are also responsible for a number of infections and diseases, some of which are severe.

Several groups of streptococcal bacteria are summarized under the term Streptococcus viridans. They can cause pathological processes such as tooth decay and inflammation.

Science attributes Streptomyces somaliensis to bacteria. As a rule, this form of bacteria is not pathogenic for humans, but it can nevertheless trigger a serious illness if the immune system is weakened. Vaccinations are not possible
