The Journal of Bacteriology is a monthly peer-reviewed scientific journal established in 1916. It is published by the American Society for Microbiology and the editor in chief is George A. O'Toole Jr. ( Dartmouth College ).
Obtaining a culture with a unified cell-cycle stage is useful for biological research where a particular stage in the cell cycle is desired (such as the culturing of parasitized cells [3]). Since cells are too small for certain research techniques, a synchronous culture can be treated as a single cell; the number of cells in the culture can be ...
A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used as research tools in molecular biology.

Colony-forming units are used to quantify results in many microbiological plating and counting methods, including: The pour plate method wherein the sample is suspended in a Petri dish using molten agar cooled to approximately 40–45 °C (just above the point of solidification to minimize heat-induced cell death).
For example, one study [12] used serial passage in baboons to create a strain of HIV-2 that is particularly virulent to baboons. Typical strains of HIV-2 only infect baboons slowly. [12] This specificity makes it challenging for scientists to use HIV-2 in animal models of HIV-1, because the animals in the model will only show symptoms slowly.
Gamma phage, an example of virus particles (visualised by electron microscopy) Virology is the scientific study of biological viruses.It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they ...
The second reason is that haploid cells of one mating type, upon cell division, often produce cells of the opposite mating type. An analysis of the ancestry of natural S. cerevisiae strains concluded that outcrossing occurs very infrequently (only about once every 50,000 cell divisions). [ 32 ]
