Hemolysin Wikipedia

Hemolysin - Wikipedia.

Alpha-hemolysin from uropathogenic E. coli produces extra-intestinal infections and can cause cystitis, pyelonephritis, and sepsis. Alpha-hemolysin from Staphylococcus aureus can cause severe diseases, such as pneumonia. Aerolysin from Aeromonas sobria infects the intestinal tract, but it might also cause sepsis and meningitis..


Hemolysis - Wikipedia.

Hemolysis or haemolysis (/ h i: ' m ? l I s I s /), also known by several other names, is the rupturing of red blood cells (erythrocytes) and the release of their contents into surrounding fluid (e.g. blood plasma).Hemolysis may occur in vivo or in vitro.. One cause of hemolysis is the action of hemolysins, toxins that are produced by certain pathogenic bacteria or fungi..


Nanopore sequencing - Wikipedia.

Nanopore sequencing is a third generation approach used in the sequencing of biopolymers -- specifically, polynucleotides in the form of DNA or RNA.. Using nanopore sequencing, a single molecule of DNA or RNA can be sequenced without the need for PCR amplification or chemical labeling of the sample. Nanopore sequencing has the potential to offer relatively low-cost ....


Vibrio vulnificus - Wikipedia.

Vibrio vulnificus is a species of Gram-negative, motile, curved rod-shaped (bacillus), pathogenic bacteria of the genus Vibrio.Present in marine environments such as estuaries, brackish ponds, or coastal areas, V. vulnificus is related to V. cholerae, the causative agent of cholera. At least one strain of V. vulnificus is bioluminescent.. Infection with V. vulnificus leads to rapidly expanding ....


Plasmin - Wikipedia.

Plasmin is a serine protease that acts to dissolve fibrin blood clots. Apart from fibrinolysis, plasmin proteolyses proteins in various other systems: It activates collagenases, some mediators of the complement system, and weakens the wall of the Graafian follicle, leading to ovulation.Plasmin is also integrally involved in inflammation. It cleaves fibrin, fibronectin, ....


Streptococcus agalactiae - Wikipedia.

Streptococcus agalactiae (also known as group B streptococcus or GBS) is a gram-positive coccus (round bacterium) with a tendency to form chains (as reflected by the genus name Streptococcus).It is a beta-hemolytic, catalase-negative, and facultative anaerobe.S. agalactiae is the most common human pathogen of streptococci belonging to group B of the Rebecca ....


Staphylococcus aureus alpha toxin - Wikipedia.

Alpha-toxin, also known as alpha-hemolysin (Hla), is the major cytotoxic agent released by bacterium Staphylococcus aureus and the first identified member of the pore forming beta-barrel toxin family. This toxin consists mostly of beta-sheets (68%) with only about 10% alpha-helices.The hly gene on the S. aureus chromosome encodes the 293 residue protein monomer, ....


Francisella tularensis - Wikipedia.

Francisella tularensis is a pathogenic species of Gram-negative coccobacillus, an aerobic bacterium. It is nonspore-forming, nonmotile, and the causative agent of tularemia, the pneumonic form of which is often lethal without treatment.It is a fastidious, facultative intracellular bacterium, which requires cysteine for growth. Due to its low infectious dose, ease of spread by aerosol, ....


ATP-binding cassette transporter - Wikipedia.

The ATP-binding cassette transporters (ABC transporters) are a transport system superfamily that is one of the largest and possibly one of the oldest gene families.It is represented in all extant phyla, from prokaryotes to humans. ABC transporters belong to translocases.. ABC transporters often consist of multiple subunits, one or two of which are transmembrane proteins and one or ....

Bordetella - Wikipedia.

Bordetella (/ ? b ?:r d ? ' t e l ? /) is a genus of small (0.2 - 0.7 um), gram-negative coccobacilli of the phylum Pseudomonadota. Bordetella species, with the exception of B. petrii, are obligate aerobes, as well as highly fastidious, or difficult to culture.All species can infect humans. The first three species to be described (B. pertussis, B. parapertussis, B. bronchiseptica ....


Listeria monocytogenes - Wikipedia.

Listeria monocytogenes is the species of pathogenic bacteria that causes the infection listeriosis.It is a facultative anaerobic bacterium, capable of surviving in the presence or absence of oxygen. It can grow and reproduce inside the host's cells and is one of the most virulent foodborne pathogens: 20 to 30% of foodborne listeriosis infections in high-risk individuals may ....


Listeria - Wikipedia.

Listeria is a genus of bacteria that acts as an intracellular parasite in mammals. Until 1992, 10 species were known, each containing two subspecies. By 2020, 21 species had been identified. The genus is named in honor of the British pioneer of sterile surgery Joseph Lister. Listeria species are Gram-positive, rod-shaped, and facultatively anaerobic, and do not produce ....


Transmembrane protein - Wikipedia.

A transmembrane protein (TP) is a type of integral membrane protein that spans the entirety of the cell membrane.Many transmembrane proteins function as gateways to permit the transport of specific substances across the membrane. They frequently undergo significant conformational changes to move a substance through the membrane. They are usually highly hydrophobic and ....


Bacillus cereus - Wikipedia.

Bacillus cereus is a Gram-positive, rod-shaped, facultatively anaerobic, motile, beta-hemolytic, spore-forming bacterium commonly found in soil, food and marine sponges. The specific name, cereus, meaning "waxy" in Latin, refers to the appearance of colonies grown on blood agar.Some strains are harmful to humans and cause foodborne illness, while other strains can be ....

Exotoxin - Wikipedia.

Membrane-damaging toxins exhibit hemolysin or cytolysin activity in vitro. However, induction of cell lysis may not be the primary function of the toxins during infection. At low concentrations of toxin, more subtle effects such as modulation of host cell signal transduction may be observed in the absence of cell lysis..
