Detection of listeriolysin, the thiol-dependent hemolysin in Listeria monocytogenes, Listeria ivanovii, and Listeria seeligeri.
The listeriolysin gene from a weakly hemolytic but virulent strain of Listeria monocytogenes serotype 1/2a was cloned in Escherichia coli K-12. Recombinants were identified on the basis of their cross-reactivities to hyperimmune antisera raised against streptolysin O and listeriolysin. Low levels of hemolytic activity were detected in crude lysates of strains harboring the listeriolysin gene. I...
متن کاملComplete genome sequence of Listeria seeligeri, a nonpathogenic member of the genus Listeria.
We report the complete and annotated genome sequence of the nonpathogenic Listeria seeligeri SLCC3954 serovar 1/2b type strain harboring the smallest completely sequenced genome of the genus Listeria.
متن کاملProduction, purification and characterization of hemolysins from Listeria ivanovii and Listeria monocytogenes Sv4b.
In culture supernatants of both Listeria ivanovii and Listeria monocytogenes Sv4b, for the first time a hemolysin of molecular weight 58 kDa was identified, which had all the characteristics of an SH-activated cytolysin, and which was therefore identified as listeriolysin O (LLO). In the case of L. ivanovii a second major supernatant protein of molecular weight 24 kDa co-purified with LLO. Howe...
متن کاملGenome Sequences of the Listeria ivanovii subsp. ivanovii Type Strain and Two Listeria ivanovii subsp. londoniensis Strains
We present the complete genomes of Listeria ivanovii subsp. ivanovii WSLC 3010 (ATCC 19119(T)), Listeria ivanovii subsp. londoniensis WSLC 30151 (SLCC 8854), and Listeria ivanovii subsp. londoniensis WSLC 30167 (SLCC 6032), representing the type strain of the species and two strains of the same serovar but different properties, respectively.
متن کاملDistinct Neurotoxicity Profile of Listeriolysin O from Listeria monocytogenes
Cholesterol-dependent cytolysins (CDCs) are protein toxins that originate from Gram-positive bacteria and contribute substantially to their pathogenicity. CDCs bind membrane cholesterol and build prepores and lytic pores. Some effects of the toxins are observed in non-lytic concentrations. Two pathogens, Streptococcus pneumoniae and Listeria monocytogenes, cause fatal bacterial meningitis, and ...
