Bacteria, viruses, fungi and parasites Gastroenteritis
Overview. A pathogen is a biological agent, or germ, that causes disease to its host by interrupting normal body processes. Bacteria, viruses, fungi and parasites are all common types of pathogens that can cause pathogenic, or infectious, diseases. These pathogens can be found in the air, soil and water, and infection can occur as a result of touching, eating or drinking something that is infected with a germ. Diseases caused by microorganisms in humans are known as pathogenic diseases. The word pathogen is derived from a Greek word that means 'giving rise to suffering'. These diseases can be caused by a number of agents like bacteria, viruses, fungi, etc. All these pathogenic agents can lead to a variety of diseases and conditions. There are many good bacteria that live on and within the human body systems. These good bacteria help our immune system keep away pathogenic bacteria. Although most bacteria are harmless or often beneficial, several are pathogenic. One of the bacterial diseases with the highest disease burden is tuberculosis, caused by the bacterium Mycobacterium tuberculosis, which kills about 2 million people a year, mostly in sub-Saharan Africa. 1 Bacterial gastroenteritis is caused by enteric, pathogenic bacteria. 2  These pathogenic species are usually distinct from the usually harmless bacteria of the normal gut flora. 3  But a different strain of the same species may b Pathogenic bacteria contribute to other globally important diseases, such as pneumonia, which can be caused by bacteria such as Streptococcus and Pseudomonas, and foodborne illnesses, which can be caused by bacteria such as Shigella, Campylobacter, and Salmonella. 1 Bacterial gastroenteritis is caused by enteric, pathogenic bacteria. 2  These pathogenic species are usually distinct from the usually harmless bacteria of the normal gut flora. 3  But a different strain of the same species may be pathogenic. Once you are infected bacteria grow and reproduce inside the cells of your body. As they grow and divide, many bacteria make toxins (poisons). These toxins can damage your cells. Some bacteria damage your cells directly as they grow. Disease symptoms such as a high temperature, headaches and rashes can be caused by the damage and toxins or by the way your body responds to the damage and toxins produced by the bacteria.  Diseases that are caused by pathogens or infectious agents like bacteria, fungi, parasites, and viruses are called pathogenic diseases. While presenting a list of pathogenic diseases, this Buzzle article will cover some information on pathogenesis of a disease. These diseases can be caused by a number of agents like bacteria, viruses, fungi, etc. All these pathogenic agents can lead to a variety of diseases and conditions. There are many good bacteria that live on and within the human body systems. These good bacteria help our immune system keep away pathogenic bacteria. Conversely, a number of diseases that impact humans are caused by bacteria. Bacteria that cause disease are called pathogenic bacteria, and they do so by producing poisonous substances called endotoxins and exotoxins. These substances are responsible for the symptoms that occur with bacteria related diseases. The symptoms may range from mild to serious, and some can be deadly These pathogens can cause pneumonia or urinary tract infection and may be involved in coronary heart disease. Other groups of intacellular bacterial pathogens include: Salmonella, Neisseria, Brucella, Mycobacterium, Listeria, Francisella, Legionella, and Yersinia pestis. 1 Bacterial gastroenteritis is caused by enteric, pathogenic bacteria. 2  These pathogenic species are usually distinct from the usually harmless bacteria of the normal gut flora. 3  But a different strain of the same species may be pathogenic. Harmful bacteria may also emit toxins that damage the body. Common pathogenic bacteria and the types of bacterial diseases they cause include: Escherichia coli and Salmonella cause food poisoning. Helicobacter pylori cause gastritis and ulcers. Neisseria gonorrhoeae causes the sexually transmitted disease gonorrhea. Neisseria meningitidis causes meningitis.  Although the vast majority of bacteria are harmless or beneficial, a few pathogenic bacteria can cause infectious diseases. One of the bacterial diseases with the highest disease burden is tuberculosis, caused by the bacterium Mycobacterium tuberculosis, which kills about 2 million people a year, mostly in sub-Saharan Africa.
