This causes a urinary tract infection. Infections caused by exogenous bacteria occurs when microbes that are noncommensal enter a host. [ 6 ] These microbes can enter a host via inhalation of aerosolized bacteria, ingestion of contaminated or ill-prepared foods, sexual activity, or the direct contact of a wound with the bacteria.
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
Calicivirus infection (Norovirus and Sapovirus) No Campylobacter species Campylobacteriosis: Stool culture Erythromycin can be used in children, and tetracycline in adults. No usually Candida albicans and other Candida species Candidiasis (Moniliasis; Thrush) oral candidiasis, the person's mouth for white patches and irritation.
Pathogenic bacteria are also the cause of high infant mortality rates in developing countries. [5] A GBD study estimated the global death rates from (33) bacterial pathogens, finding such infections contributed to one in 8 deaths (or ~7.7 million deaths), which could make it the second largest cause of death globally in 2019.

Adult-onset immunodeficiency syndrome is a type of immunodeficiency. It is linked to vulnerability to disseminated infections brought on by opportunistic pathogens . People with this condition have increased levels of anti-interferon-gamma autoantibodies .
Anaerobes are able to cause all types of intracranial infections. These often cause subdural empyema, and brain abscess, and rarely cause epidural abscess and meningitis. The origin of brain abscess is generally an adjacent chronic ear, mastoid, or sinus infection [6] oropharynx, teeth [7] or lungs. [8]
Mycobacterium tuberculosis is a species of bacteria that causes tuberculosis, a respiratory infection. [13] Pseudomonas aeruginosa is a bacterium that can cause respiratory infections. It is frequently associated with cystic fibrosis and hospital-acquired infections. [14] Salmonella is a genus of bacteria, known to cause gastrointestinal ...
Infection can be caused by bacteria or fungi, and is classified as exogenous (infection introduced by direct inoculation as in surgery or penetrating trauma), or endogenous (organisms carried by blood vessels to the eye from another site of infection and is more common in people who have an immunocompromised state).
