The communal benefits of multicellular cooperation include a cellular division of labour, accessing resources that cannot effectively be used by single cells, collectively defending against antagonists, and optimising population survival by differentiating into distinct cell types. [156] For example, bacteria in biofilms can have more than five ...
Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea ). Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped ...
Bacterial taxonomy is subfield of taxonomy devoted to the classification of bacteria specimens into taxonomic ranks. In the scientific classification established by Carl Linnaeus, [ 1] each species is assigned to a genus resulting in a two-part name. This name denotes the two lowest levels in a hierarchy of ranks, increasingly larger groupings ...
In most bacteria the most numerous intracellular structure is the ribosome, the site of protein synthesis in all living organisms. All prokaryotes have 70S (where S= Svedberg units) ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol. The 70S ribosome is made up of a 50S and 30S subunits.
Pathogenic bacteria. Neisseria gonorrhoeae (small red dots) in pus from a man with a urethral discharge ( Gram stain) Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and are often beneficial but others can cause infectious ...
Streptococcus zooepidemicus. Viridans streptococci. Streptococcus anginosus group. Streptococcus is a genus of gram-positive coccus ( pl.: cocci) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. [ 2]
Salmonella. Salmonella enteritidis; Salmonella typhi; Salmonella typhimurium; Serratia marcescens; Shigella dysenteriae; Spirillum volutans; Staphylococcus
This article lists the genera of the bacteria.The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [1] and National Center for Biotechnology Information (NCBI). [2]
