Inflammation of brain tissue. Infection and immune-mediated processes are different causes, so the anatomical term does not establish one organism or mechanism.

An infectious disease caused by Treponema pallidum.

Infection with larval stages of Echinococcus tapeworms. Tissue lesions can develop after ingestion of eggs, distinguishing the human intermediate-host infection from an adult intestinal tapeworm.^[ref]

A disease transmitted through water carrying an infectious agent or another harmful exposure. The category describes a route, not one pathogen; sanitation and drinking-water treatment interrupt different parts of that route.

A parasitic disease caused by the guinea worm Dracunculus medinensis. Ingestion of infected aquatic intermediate hosts connects contaminated drinking water with later development of an emerging adult worm.^[ref]

The infection caused by variola virus. Varioloid describes modified disease, rather than a distinct infection.

The primary infection caused by varicella-zoster virus; distinct from smallpox.

A genital-ulcer infection caused by Haemophilus ducreyi. It is distinct from syphilis; lesion appearance can overlap with other infections and does not alone establish the causative organism.^[ref]

A disease caused by Bacillus anthracis, with manifestations depending on the route of exposure. Spore persistence connects the organism’s biology with environmental transmission.^[ref]

A historical clinical designation for disseminated suppurative infection with multiple secondary foci; distinguish the term from a modern universal definition of sepsis.

A historical and clinical term associated with systemic infection involving the bloodstream; its use should not be treated as identical to every modern definition of sepsis.

A parasitic infection acquired through ingestion of infected meat containing Trichinella larvae.^[ref]

Infection established at a site distant from its primary focus through spread of microorganisms, commonly through the blood.

Presence of bacteria in the blood; it is not synonymous with every systemic inflammatory illness or with all forms of sepsis.

A sexually transmitted infection caused by Neisseria gonorrhoeae. Different mucosal sites can be involved, and absence of symptoms does not establish absence of infection.^[ref]

An infection caused by bacteria.

An infection involves invasion and multiplication of an infectious agent in a host. Bacteria are one possible cause; an agent capable of causing disease is a pathogen. The National Cancer Institute defines infection through invasion and growth in the body. ^[ref].

In a SIR model, acquiring infection moves a member of the susceptible compartment into the infectious compartment. That immediate transition is a model assumption: the SEIR model instead includes an exposed stage before infectiousness. Specify these states when translating a biological process into compartmental models.

An infection case is one affected individual counted in an outbreak model. A count of eventual cases can include exposures that have occurred but whose delayed transfer into the infective compartment is still pending.

A language-defined conversion from a numeric type to another admitted numeric type, such as Scala's conversion of an Int argument to Double. It can make an overloaded method applicable even when the argument's static type differs from the parameter type. It does not imply a subtyping relationship between every pair of numeric types or exact representation of every source value; sufficiently large integers can lose precision in a floating-point target. ^[ref]

Interacting cells, molecules and tissues that recognize and respond to threats or altered biological material. Its responses include both defense and regulation, rather than unrestricted elimination of every foreign molecule.

A calcium salt of hypochlorite. It must be distinguished from the variable commercial composition of bleaching powder.
