Pathogen

Colds are one of the most common infectious diseases. In poorer countries they are high on the list of causes of death. This is due to the tiny rhinoviruses, which have special properties.

Retroviruses have influenced the human genome for millions of years. But major infectious diseases can also be traced back to retroviruses.

Rhizopods, which are to be counted among the protozoa, do not form a uniform type or class of unicellular organisms with a defined cell nucleus (eukaryotes), but they all combine only the ability to develop pseudopodia. Embody rhizopods

Eating infected beef that has not been sufficiently heated can lead to infection with beef tapeworm (Taenia saginata). It is a parasitosis with a benign course. In Central Europe the disease is more effective, due to its good

Diseases caused by rickettsia were common in ancient times. During Napoleon's wars, more than 125,000 soldiers died of lice-borne typhus. Rickettsioses - infectious diseases caused by rickettsiae

According to the definition, a parasite is an organism that attacks and mostly harms another living being in order to survive. In addition, the infected organism is used for its own reproduction purposes.

The bacterium Salmonella Typhi causes the infectious disease typhoid. It is a pathogenic enterobacterium that is very likely to cause disease. An infectious dose of 100 to 1000 pathogens is already sufficient. The morbidity rate

Suction worms are a class of flatworms. They are parasites.

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

Infection with rotaviruses leads to serious gastrointestinal problems. It mainly affects young children and babies and is highly contagious. The transmission takes place in the form of a smear infection.

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

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 mucous membranes of the nose. For healthy people, contact with Staphylococcus capitis is no longer tragic. Immune speed

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 rubella virus only affects humans and triggers rubella in them. This childhood disease is highly contagious, but when it occurs it leads to lifelong immunity. The rubella virus (also rubella virus) causes characteristic

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

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

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