Bacterial type IV pilins are similar in structure to the component flagellins of Archaeal flagella.

* Bacterial flagella are helical filaments, each with a rotary motor at its base which can turn clockwise or counterclockwise.

* Bacterial flagella grow by the addition of flagellin subunits at the tip ; archaeal flagella grow by the addition of subunits to the base.

* Bacterial flagella are thicker than archaella Archaellum, and the bacterial filament has a large enough hollow " tube " inside that the flagellin subunits can flow up the inside of the filament and get added at the tip ; the archaellum is too thin ( 12-15 nm ) to allow this.

Bacterial cell walls are made of peptidoglycan ( also called murein ), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids.

Bacterial cell walls are different from the cell walls of plants and fungi which are made of cellulose and chitin, respectively.

Bacterial and viral acute sinusitis are difficult to distinguish.

Bacterial lawns ( often of Serratia marcescens ) are also used extensively when as an assay method when using bacteriophage as tracers in studies of groundwater flow.

Bacterial toxins such as those from Bacillus thuringiensis which are evolved to affect the gut of Lepidoptera have been used in sprays of bacterial spores, toxin extracts and also by incorporating genes to produce them within the host plants.

Bacterial and fungal proteases are particularly important to the global carbon and nitrogen cycles in the recycling of proteins, and such activity tends to be regulated in by nutritional signals in these organisms.

Bacterial DNAs are methylated periodically throughout the genome.

Bacterial species possesses distinct DHFR enzymes ( based on their pattern of binding diaminoheterocyclic molecules ), but mammalian DHFRs are highly similar.

Bacterial strains that have the cagA gene are associated with an ability to cause ulcers.

Bacterial cells are much smaller than human cells, and there are at least ten times as many bacteria as human cells in the body ( approximately 10 < sup > 14 </ sup > versus 10 < sup > 13 </ sup >).

Bacterial cells are harvested via centrifugation and the resulting cell pellet lysed either by physical means or by means of detergents and enzymes such as lysozyme.

Bacterial endospores are most resistant to disinfectants, but some viruses and bacteria also possess some tolerance.

Bacterial tektons are typical of the lake.

In addition to the filter fluorometers shown above, fluorometers are used extensively in Life Science research for various assays such as Alkaline Phosphatase, Bacterial Viability, B-Galactosidase, Cell Proliferation, RNA Quantitation, DNA Quantitation, Enzyme Assays, Protein Quantitation, and Reporter Gene Assays.

Bacterial contaminants are ubiquitous, and foods left unused too long will often be contaminated by substantial amounts of bacterial colonies and become dangerous to eat, leading to food poisoning.

Bacterial Halorhodopsins or Proton pumps are the two classes of proteins used for inhibitory optogenetics, achieving inhibition by increasing cytoplasmic levels of halides ( Cl -) or decreasing the cytoplasmic concentration of protons, respectively.

Bacterial organisms are sometimes included in a flora, and sometimes the terms bacterial flora and plant flora are used separately.

Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells.

Bacterial vaginosis ( BV ) or less commonly vaginal bacteriosis is a disease of the vagina caused by bacteria.

Bacterial vaginosis ( BV ) occurs more often in lesbians, but it is unclear if BV is transmitted by sexual contact ; it occurs in celibate as well as sexually active women.

Bacterial lawn is a term used by microbiologists to describe the appearance of bacterial colonies when all the individual colonies on a petri-dish agar plate merge to form a field or mat of bacteria.

Bacterial genomic DNA is not recognized by these restriction enzymes.

* Bacterial conjugation, a process in which a bacterial cell transfers genetic material to another cell by cell-to-cell contact.

* Bacterial conjugation, a process in which a bacterial cell transfers genetic material to another cell by cell-to-cell contact.

* Bacterial leaf blight of rice, caused by the bacterium Xanthomonas oryzae ( Uyeda & Ishiyama ) Dowson.

Bacterial processes leading to ulceration can be caused by Mycobacterium tuberculosis ( tuberculosis ) and Treponema pallidum ( syphilis ).

* Bacterial vaginosis: vaginitis caused by Gardnerella ( a bacterium ).

* Bacterial vaginosis: vaginitis caused by Streptococcus spp ..

Bacterial vaginosis has been linked to preterm birth raising the risk by a factor of 1. 5 – 3.

* Bacterial leaf scorch, a disease state caused mainly by a xylem-plugging bacterium

* Bacterial flagellin and plant disease resistance, published by Zipfel.

Bacterial transformation may be referred to as a stable genetic change brought about by the uptake of naked DNA ( DNA without associated cells or proteins ) and competence refers to the state of being able to take up exogenous DNA from the environment.

* Bacterial conjunctivitis: A review for internists AHMAD B. TARABISHY and BENNIE H. JENG.

Bacterial culture of H. influenzae is performed on agar plates, the preferable one being chocolate agar, with added X ( hemin ) & V ( NAD ) factors at 37 ° C in a CO < sub > 2 </ sub >- enriched incubator.

Bacterial reduction of seawater sulfate or a euxinic ( anoxic and H < sub > 2 </ sub > S-containing ) water column is a necessary source of that sulfide.

Bacterial cultures of renal tissue are almost always positive.

Bacterial sulfate reduction ( BSR ) can only occur at temperature from 0 up to 60 – 80 ° C because above that temperature almost all sulfate-reducing microbes can no longer metabolize.
