Causes a severe form of pneumonia with a relatively high mortality rate, known as legionellosis or Legionnaires' disease. Mycoplasma pneumoniae Usually occurs in younger age groups and may be associated with neurological and systemic (e.g. rashes) symptoms. See Mycoplasma pneumonia. Atypical pneumonia can also have a fungal, protozoan, or viral ...
Immunocompromised individuals are especially vulnerable to bacteria that are typically nonpathogenic; because of a compromised immune system, disease occurs when these bacteria gain access to the body's interior. Genes have been identified that predispose disease and infection with nonpathogenic bacteria by a small number of persons. [3]
Medications are usually not needed as hand, foot, and mouth disease is a viral disease that typically resolves on its own. Under research [15] [16] Sin Nombre virus: Hantavirus Pulmonary Syndrome (HPS) No Heartland virus: Heartland virus disease No Helicobacter pylori: Helicobacter pylori infection No Escherichia coliO157:H7, O111 and O104:H4
Nontuberculous mycobacteria (NTM) are all the other mycobacteria that can cause pulmonary disease resembling tuberculosis, lymphadenitis, skin disease, or disseminated disease. Although over 150 different species of NTM have been described, pulmonary infections are most commonly due to Mycobacterium avium complex (MAC), Mycobacterium kansasii ...
PSTVd was the first pathogen of a eukaryotic organism for which the complete molecular structure has been established. Over thirty plant diseases have since been identified as viroid-, not virus-caused, as had been assumed. [88] [93] Four additional viroids or viroid-like RNA particles were discovered between 2009 and 2015. [86]
Infectious disease – illness or disorder when pathogenic (disease-causing) microorganisms, such as bacteria, viruses, fungi, or parasites invade and multiply within the body of a host organism and release toxins, causing various clinical symptoms which can potentially lead to severe health complications or even death. Infectious diseases can ...
Their growth and reproduction within their hosts can cause disease. "Germ" refers to not just a bacterium but to any type of microorganism, such as protists or fungi, or other pathogens that can cause disease, such as viruses, prions, or viroids. [1] Diseases caused by pathogens are called infectious diseases. Even when a pathogen is the ...
Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. [a] Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. [8] Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. [8]
