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 ...
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 ).
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.
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.
Run-and-tumble motion is a movement pattern exhibited by certain bacteria and other microscopic agents. It consists of an alternating sequence of "runs" and "tumbles": during a run, the agent propels itself in a fixed (or slowly varying) direction, and during a tumble, it remains stationary while it reorients itself in preparation for the next run.
A method was introduced to hybridize a large number of DNA samples against numerous DNA probes on a single membrane. The samples would need to be separated into individual lanes within the membrane, which would then be rotated to allow simultaneous hybridization with multiple DNA probes.
In this image, a gene from one bacterial cell is moved to another bacterial cell. 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 ...
Bacteriology is the branch and specialty of biology that studies the morphology, ecology, genetics and biochemistry of bacteria as well as many other aspects related to them. This subdivision of microbiology involves the identification, classification, and characterization of bacterial species. [ 1 ]
