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

Human adenoviruses are a group of DNA viruses discovered in 1953 by Wallace P. Rowe. The American cancer researcher and virologist isolated the viruses from the tonsils of humans, the so-called adenoids. From this derives

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

Human herpes viruses are host-specific viruses from the Herpesviridae family, all of which are pathogenic to humans. In addition to cold sores, this group of infections mainly includes genital herpes, the pathogens of which both remain in their host for life

Human papillomaviruses appear in two main forms in humans: As warts on the skin, they are known to be an annoying but rather harmless disease. Viruses transmitted sexually or through other intimate contact are some types of

The human herpes virus 6, called HHV-6 for short, belongs to the herpes virus family, which is divided into an alpha, beta and gamma subfamily. HHV-6 belongs to the subfamily of beta herpes viruses, which have a very narrow host range and are themselves

Human Herpesvirus 8 (HHV 8) is a virus from the Herpesviridae family. It belongs to the subgroup of gamma herpes viruses. It was discovered in 1994 by virologist Patrick S. Moore and his wife Yuan Chang at Coulumbia University

Germs are everywhere. Humans wear them on the skin, in the body and spread them by coughing, sneezing and any form of physical contact. Animals carry germs from one end of the country to the other, often even from one continent to the next. Whether armrest

The influenza virus is a virus that manifests itself through a respiratory infection. There are different types of this virus (also called the flu virus) that belong to the orthomyxoviruses. Depending on the genus of the virus, influenza can be

The JC virus, like the BK virus, belongs to the polyomaviruses, a group of non-enveloped DNA viruses. It occurs worldwide and is already transmitted in childhood, whereby it can persist for life. The pathogen triggers the progressives

As Klebsiella, a group of bacteria is known that belongs to the gram-negative rod bacteria and thus to the enterobacteria family. Almost all sub-genera of the bacterial species are completely harmless to a healthy person, however

Klebsiella granulomatis is a non-flagellated, gram-negative, rod-shaped bacterium from the enterobacteria family. It lives facultatively anaerobically in the cytoplasm of large, mononuclear cells and is the causative agent of the sexually transmitted disease donovanosis. The

Klebsiella pneumoniae is one of the hospital germs. The bacterium mainly damages people who are already in poor health.

Cocci come in several forms of organization and can lead to severe infections if they multiply and the infected person has a weakened immune system. Different cocci subspecies are so adaptable that they

The word alga has negative meanings in the minds of many Europeans: algae plague in the Mediterranean, algae growth in ponds or the eutrophication of water by algae. Slowly but steadily, however, knowledge about the algae is increasing as possible - perhaps

They are invisible to the human eye and yet we could hardly live without them. Lactobacillus, lactic acid bacteria, are an important part of our intestinal flora. They ensure a balance there, balance our immune system and

Legionella are rod-shaped bacteria of the Legionellaceae family, flagged on one of the poles. The bacteria are almost omnipresent and are mainly found in freshwater reservoirs, but have also been detected in salt water. You are the

Leishmania infantum is a small bacterium from the Leishmania family and lives as a parasite obligate intracellularly in macrophages in humans and other vertebrates. In order to maintain its species, the bacterium changes host between sandm

Leishmania brasiliensis are small, flagellated protozoa that belong to the Leishmania bacterial strain, subgenus Viannia. They live parasitically in macrophages, which they phagocytosed into without being damaged. You are responsible for the

Leishmania tropica belong to a large group of flagellated protozoa that live intracellularly in macrophages in skin tissue and require the host switch between sand fly or butterfly mosquito and vertebrates for their distribution. You are the cause
