Microorganisms had been seen in the cytoplasm of the eggs of these species, but this alone did not prove that they were the cause of the reproductive isolation.

microorganisms Single-celled living organisms that can be seen only with the aid of a microscope.
microparasite Small (or very small) parasite that multiplies within the host of interest. Examples are protistan and prokaryotic parasites.
When microorganisms penetrate skin or epithelium lining respiratory, digestive, or urinary tracts, inflammation results.
- A cell microorganism that manifests new characteristics due to a change in its genetic material.
Mutation
- A change in the genetic information.
Dangerous microorganism that could be harboured and transmitted to poultry and humans through rat and mouse urine.
Bacteria are microorganisms that come in various shapes. They can be spheres, they can be rods, or they can be spirals. There are bacteria that are bad, that we call pathogenic, and they will cause diseases, but there's also good bacteria.
A prokaryotic microorganism in Domain Bacteria.
balanced polymorphism
A type of polymorphism in which the frequencies of the coexisting forms do not change noticeably over many generations.
Aerobe. A microorganism that grows in the presence of oxygen. See Anaerobe.
Prototroph
A microorganism that is able to grow on minimal medium containing only a carbon source and inorganic salts.
In many species of microorganisms individuals can be divided into two types. Mating can take place only between individuals of opposite mating types due to the interaction of cell surface components.
phage - viruses for microorganisms
photosynthesis - use of light to carry out reductive biochemical processes necessary for life. Pigments capture light energy in much the same way as an antenna captures a radio or tv signal.

Cilia and flagella are motile cellular appendages found in most microorganisms and animals, but not in higher plants. In multicellular organisms, cilia function to move a cell or group of cells or to help transport fluid or materials past them.
In the mid-1800's, the process of pasteurization was described by Louis Pasteur, who discovered that heating solutions to moderate temperatures would reduce the numbers of contaminating live microorganisms.

Hydrochloric acid does not directly function in digestion: it kills microorganisms, lowers the stomach pH to between 1.5 and 2.5; and activates pepsinogen. Pepsinogen is an enzyme that starts protein digestion.
Bacterium (plural: bacteria) A one-celled microorganism that contains no nucleus. Some bacteria are helpful, such as those in the intestines that help digest food, while others cause disease.
Unicellular often environmentally resistant dormant or reproductive body produced by plants and some microorganisms and capable of development into a new individual either directly or after fusion with another spore.

When an organism is threatened by microorganisms, viruses, or cancer cells, the immune response acts to provide protection.
Normally, the immune system does not mount a response against self. This lack of an immune response is called tolerance.
