, autovaccinations (pl) (nouns)
1. The injection of an autovaccine into the body.
2. The use of antigenic products derived from an invading organism or the diseased tissue of an individual to invoke antibody synthesis.
, autovaccines (pl) (nouns)
A bacterial vaccine derived from micro-organism cultures obtained from the patient's own tissues or secretions.

Animal movements of the handa are said to be autovisible. Chimpanzees are able to imitate, using even parts of their own body which they cannot see, simple movements (nonautovisible versus autovisible or hand movements).
autovoxiphillia (s) (noun)
, autovoxiphillias (pl)
The fondness or adoration of a person’s own voice: Marie loved to sing and even recorded her songs to listen to, which showed her strong tendency for autovoxiphillia.
A reference to a parasite that passes through the different stages of its life cycle in the same host individual.
autoxidation, auto-oxidation, autooxidation
1. The oxidation by direct combination with oxygen (as in air) at ordinary temperatures: "The rancidity of fats and oils is caused by autoxidation."
2. The combination of a substance with molecular oxygen at ordinary temperatures.
autozooid (s) (noun)
, autozooids (pl)
An independent polyp capable of feeding itself: An autozooid
is a completely formed alcyonarian zooid and is different when compared to a siphonozooid.
A "polyp" is described as a cylindrical organism with a thin body-wall consisting of two single layers of cells, the "ectoderm" and the "endoderm" separated by a gelatinous noncellular layer or "mesogloea".
At one end there may be a mouth which is usually surrounded by tentacles. Polyps may be single (e.g, "hydra") or colonial (e.g. the coral-forming organisms). The latter are formed by repeated budding from a parent polyp.
In such colonies a tube or "coenosarc" links the body-cavities of all the individuals with one another. There may be many different kinds of polyps in a colony, each specialized for some different function, such as feeding, reproduction, protecting, etc.
Pertaining to genes in a homozygote that are copies of the same ancestral gene as a result of a mating between related individuals: When two alleles at a locus come from a common predecessor by inbreeding, the genotype is termed autozygous.
, more auxoautotrophic, most auxoautotrophic
1. A reference to an increase in the nursing, tending, and self-nourishing; of plants: Farmers are specialists in the care auxoautotrophic wheat, corn, and other food products.
2. Relating to an organism capable of increasing the synthesizing of its own food from inorganic substances, using light or chemical energy: Green plants, algae, and certain bacteria are examples of auxoautotrophic vegetation.
bioautography (s) (noun)
, bioautographies (pl)
1. A bioassay of certain compounds, usually antibiotics or vitamins, by evaluating their ability to enhance the growth of some organism and to repress that of others: Using the bioautography stains for enzymes which could not be visualized by any other procedure have been developed
2. Classification of organic material by using solid absorbents that have affinities for specific elements.
3. An analytical technique in which organic compounds are separated by chromatography and identified by studying their effects on microorganisms.
1. A microorganism that can derive the energy required for growth from oxidation of inorganic compounds such as hydrogen sulfide or ammonia.
2. Any autotrophic bacteria or protozoan that is not involved in the process of photosynthesis.
3. An organism that depends on chemicals for its energy and principally on carbon dioxide for its carbon.
A reference to microorganisms that obtain metabolic energy by the oxidation of inorganic substrates, such as sulphur, nitrogen, or iron; chemotrophic.
A reference to an organism that produces its own food using inorganic materials and chemosynthesis; such as, certain bacteria.
