Summary Helicobacter pylori is a gram-negative rod bacterium. There are more than 300 different strains, which are distributed worldwide, are regionally and familially abundant, and their genetic information sometimes varies considerably. What they all have in common is a whole range of different adaptation mechanisms that enable it to survive in its main reservoir, the … Helicobacter pylori
Test for a Helicobacter When detecting Helicobacter pylori, a distinction is made between so-called invasive and non-invasive methods. Invasive means that one penetrates into body tissue. There are several non-invasive test methods. With these, a colonization with Helicobacter pylori is in principle very easy to detect. One of the simplest methods uses the normal exhaled … Test for a Helicobacter | Helicobacter pylori
Infection The transmission path of Helicobacter pylori is not conclusively clarified. The possibility of oral-oral and faecal-oral transmission by excretion of the bacterium in stool and reabsorption by other persons, e.g. from water, is being discussed. Contaminated food also provides a source of absorption. The germ initially colonizes its main reservoir in humans, the lower … Infection | Helicobacter pylori
Virulence factors Furthermore, Helicobacter pylori produces urease, an enzyme that breaks down urea into ammonia and CO2. This raises the pH in the bacterium’s surrounding medium, i.e. it is converted into a less acidic environment. The neutral environment is called the ammonia mantle. Helicobacter pylori also produces virulence factors such as the vacuolating VacA and … Virulence factors | Helicobacter pylori
Lymphadenitis Definition Lymphadenitis is the swelling of lymph nodes due to inflammatory processes, usually in the context of infections. The swelling of one or more lymph nodes is called lymphadenopathy. Often the terms lymphadenitis (in the narrower sense inflammation of the lymph nodes) and lymphadenopathy (in the narrower sense swelling of the lymph nodes) are … Inflammation of the lymph nodes – How dangerous is that?
Risk potential of an inflamed lymph node The risk of permanent damage to health from an inflamed lymph node is very low. Most lymph node inflammations occur as a result of an infection of neighboring tissue, for example a swelling of the neck lymph nodes as part of a common cold. This lymph node swelling … Risk potential of an inflamed lymph node | Inflammation of the lymph nodes – How dangerous is that?
Causes The possible causes of lymph node swelling can be roughly divided into two categories: Infections and malignant processes. If an infection is the cause of the swelling, we are talking about lymphadenitis in the narrower sense, i.e. inflammation of the lymph nodes, as discussed in this article. Numerous bacterial and viral pathogens can enter … Causes | Inflammation of the lymph nodes – How dangerous is that?
Therapy The therapy of an inflammation of the lymph nodes depends crucially on the triggering cause. For example, lymph node swelling can occur for only a few days in the context of a cold or flu, and no specific therapy is required. If the lymph nodes are inflamed due to a bacterial infection, such as … Therapy | Inflammation of the lymph nodes – How dangerous is that?
Introduction If one suffers from glandular fever, one must be particularly careful with sports. Often the body is in a weakened state during this disease.

Introduction Lymph nodes, popularly known as lymph glands, belong to the group of so-called lymphatic organs, including the spleen. They are therefore a part of the immune system. Lymph nodes contain the so-called lymphocytes, a subgroup of white blood cells that serve the body’s immune defense. They play an important role in the body’s defence … Swelling of lymph nodes behind the ear
