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 ).
The increased cell length can protect bacteria from protozoan predation and neutrophil phagocytosis by making ingestion of cells more difficult. [ 1 ] [ 3 ] [ 4 ] [ 5 ] Filamentation is also thought to protect bacteria from antibiotics, and is associated with other aspects of bacterial virulence such as biofilm formation.
Horizontal gene transfer is a result of this, where bacterial genes can be transferred amongst same-generation species in a given environment, and competence is the ability of a cell to participate in the transfer. If one cell in a population living in an unfavorable environment has a mutation that results in better survivability, that gene can ...
A serotype or serovar is a distinct variation within a species of bacteria or virus or among immune cells of different individuals. These microorganisms , viruses, or cells are classified together based on their surface antigens , allowing the epidemiologic classification of organisms to a level below the species .
One process is a one-step mechanism in which proteins from the cytoplasm of bacteria are transported and delivered directly through the cell membrane into the host cell. Another involves a two-step activity in which the proteins are first transported out of the inner cell membrane, then deposited in the periplasm , and finally through the outer ...
The cell on the left is going through mitosis and its chromosomes have condensed. Cell nucleus: A cell's information center, the cell nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes, and is the place where almost all DNA replication and RNA synthesis (transcription) occur.
Transmission electron micrographs of actively growing (panel A) and nonculturable (panel B) Yersinia pestis.Bar equals 0.5 microns. Viable but nonculturable (VBNC) bacteria refers as to bacteria that are in a state of very low metabolic activity and do not divide, but are alive and have the ability to become culturable once resuscitated.
Endospore stain on Bacillus subtilis.The spore is stained green and the vegetative cell is stained a pinkish red color. Endospore staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample. [1]
