It detects the production of enhanced hemolysis which occurs when [beta]-lysin and the hemolysins
of GBS come in contact, making an arrow-shaped hemolysis pattern.
It can produce several toxins including deoxyribonuclease, lecithinase, hyaluronidase, and hemolysins
, which can lead to tissue necrosis, disseminated intravascular coagulation, intravascular thrombosis, and hemolysis.
Virulence factors include hemolysins
and Shiga toxins (Stx) [13,33].
are considered virulence factors, and some clinical strains have either the tdh gene or the trh gene, and some contain both (Joseph et al.
are produced by bacteria in order to obtain nutrients from host cells.
hydrophila virulence could involve several extracellular enzymes including proteases, hemolysins
, enterotoxins, and acetylcholinesterase.
If hemolysis occurs as a result of the fragility of the red blood cells, and/or as a result of the production of hemolysins
by certain bacteria (i.
In addition, bacterial hemolysis and hemolysins
, a subject of considerable significance with respect to bacterial identification and pathogenesis, received only one paragraph of attention.
perfringens, including four lethal toxins, hemolysins
, proteases, neuraminidase and enterotoxin.
He was also involved in research on hemolysins
, complement, and cancer.
GAMMAGARD LIQUID contains blood group antibodies that may act as hemolysins
and induce in vivo coating of red blood cells (RBC) with immune globulin.
Now, Key characters are used for species and subspecies identification include colony morphology, oxygen requirements, coagulase, clumping factor, heat-stable nuclease, hemolysins
, catalase, oxidase, alkaline phosphatase, urease, ornithine decarboxylase, pyrrolidonyl arylamidase, [beta]- galactosidase, acetoin production, nitrate reduction, esculin hydrolysis and aerobic acid production from a variety of carbohydrates including D-trehalose, Dmannitol, D-mannose, D-turanose, D-xylose, D-cellobiose, L-arabinose, maltose, -lactose, sucrose, and raffinose, and intrinsic resistance to novobiocin and polymyxin B .
