In medicine, public health, and biology, transmission is the passing of a pathogen causing communicable disease from an infected host individual or group to a particular individual or group, regardless of whether the other individual was previously infected. [ 1 ] The term strictly refers to the transmission of microorganisms directly from one ...
Pediatrics. A vertically transmitted infection is an infection caused by pathogenic bacteria or viruses that use mother-to-child transmission, that is, transmission directly from the mother to an embryo, fetus, or baby during pregnancy or childbirth. It can occur when the mother has a pre-existing disease or becomes infected during pregnancy.
Direct-contact transmission also can occur between two patients, with one serving as the source of the infectious microorganisms and the other as a susceptible host. Indirect-contact transmission This involves contact of a susceptible host with a contaminated intermediate object, usually inanimate, such as contaminated instruments, needles , or ...
Transmission by direct contact, Some diseases that are transmissible by direct contact include athlete's foot, impetigo and warts. Vehicle transmission, transmission by an inanimate reservoir (food, water, soil). [32] Vertical transmission, directly from the mother to an embryo, fetus or baby during pregnancy or childbirth.
In Latin, fomes (genitive: fomitis, plural fomites, stem fomit-) is a third-declension T-stem noun. Such nouns, like miles/militis or comes/comitis, typically lose their T (thereby becoming a syllable shorter) in the nominative singular, but retain it in all other cases. In languages derived from Latin, the French fomite, Italian fomite ...
A contagious disease is an infectious disease that is readily spread (that is, communicated) by transmission of a pathogen through contact (direct or indirect) with an infected person. [ 1] A disease is often known to be contagious before medical science discovers its causative agent. Koch's postulates, which were published at the end of the ...
This process of the second bacterial cell taking up new genetic material is called transformation. In molecular biology and genetics, transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material from its surroundings through the cell membrane (s).
Fecal–oral transmission is primarily considered as an indirect contact route through contaminated food or water. However, it can also operate through direct contact with feces or contaminated body parts, such as through anal sex. [2] [3] It can also operate through droplet or airborne transmission through the toilet plume from contaminated ...
