Pathogen

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 still trigger a serious illness if the immune system is weakened. Vaccinations are not possible

Streptomyces are bacteria belonging to the Actinobacteria. They are used to produce antibiotics.

Streptomyces sudanensis is a form of actinobacteria. The bacteria in this group are mostly beneficial, but a few specific species can cause disease. While medicinal products can be obtained from many forms of actinobacteria

A dwarf nematode is called Strongyloides stercoralis. The parasite can cause illness in humans.

T-phages are viruses which, as bacteriophages, have specialized in the exclusive infestation of Escherichia coli intestinal bacteria (coliphages). There are 7 different types known, with the designation T1 to T7, of which the even-numbered ones

Toxoplasmas are parasitic unicellular organisms whose ultimate hosts are cats. The only known representative of the Toxoplasma is Toxoplasma gondii.

Trichomonas intestinalis is a protozoon that belongs to the group of trichonomads. As a resident of the small intestine, it feeds as a commensal. Trichomonas intestinalis is believed to be responsible for a form of dysentery.

Treponema pallidum is a bacterial species from the spirochete family. The bacterium is coiled in a helix and causes various infectious diseases.

Trichomonas vaginalis belongs to the protozoa and is the causative agent of trichomoniasis. Women and men can become infected with trichomonads through unprotected sexual intercourse.

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

Herpes diseases are diverse and noticeable in a wide variety of ways. The best-known herpes virus manifests itself as burning blisters, mostly in the corners of the mouth. They are uncomfortable and often return in spite of professional treatment

Plasmodium is a unicellular, cell wallless parasite that can attack mammals, birds and reptiles and belongs to the class of Apicomplexa (formerly: Sporozoa). Of the approximately 200 known species, 4 are known to cause malaria

Veillonella parvula is a species of bacteria that is assigned to the Acidaminococcaceae. The species normally lives as commesals in the human oral flora and in the intestines. Especially with an immunodeficiency, the species can become opportunistic

Bacteria of the Vibrio genus are gram-negative bacteria. Most of these bacteria live in water. A well-known pathogen in the family is Vibrio cholerae, the causative agent of cholera.

Vibrio parahaemolyticus is a bacterial species that contains many individual strains. The bacteria prefer to live in seawater and can migrate to the human intestine, especially when eating undercooked fish and seafood

Vibrio cholerae is a bacterium from the genus Vibrions. The pathogen can cause the infectious disease cholera.

Unsightly blisters: Cold sores and genital herpes - the so-called herpes simplex viruses (HSV) are responsible for this. They come in two different variants: herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2). While
