Members ofthis group of haemolysins are produced by several species of Gram-positive bacteria \{Listeria spp., Streptococcus spp., Bacillus spp., Clostridium spp.,) and also byGram-negative Klebsiella spp. Their cytolytic activity is sensitive to oxygen andcan be restored by adding reducing compounds. TACY bind to cholesterol-containing membranes to form pores. Preincubation of the toxin with smallamounts of cholesterol inhibits hemolytic activity as well as cytolysis ofeucaryotic cells. Members ofthe group show 40-70% similarity in amino acid sequence, and contain an almost invariant Trp-rich undecapeptide sequence(ECTGLAWEWWR). The TACY are important virulence factors. Recently increased use has been made of molecular methods (PCR, hybridization) in the detection and identification of the TACY producing bacteria.}, title={Thiol-activated hemolysins as virulence markers of bacteria}, type={Text}, URL={http://www.rcin.org.pl/Content/138884/PDF/POZN271_174177_biotechnologia-2001-no3-szramka.pdf}, keywords={biotechnology}, }
