Production, 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 کاملDetection 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 کاملComparative experimental infection of Listeria monocytogenes and Listeria ivanovii in bovine trophoblasts
Listeria monocytogenes is a Gram-positive, facultative intracellular and invasive bacterium that has tropism to the placenta, and causes fetal morbidity and mortality in several mammalian species. While infection with L. monocytogenes and L. ivanovii are known as important causes of abortion and reproductive failure in cattle, the pathogenesis of maternal-fetal listeriosis in this species is po...
متن کاملGenome Sequences of Three Frequently Used Listeria monocytogenes and Listeria ivanovii Strains
We present the complete de novo assembled genome sequences of Listeria monocytogenes strains WSLC 1001 (ATCC 19112) and WSLC 1042 (ATCC 23074) and Listeria ivanovii WSLC 3009, three strains frequently used for the propagation and study of bacteriophages because they are presumed to be free of inducible prophages.
متن کاملinvestigation of listeria monocytogenes and listeria ivanovii infection in wild cage birds in shahrekord by pcr
most birds probably can carry listeria spp. asymptomatically in their intestines with varying prevalence and can transmit the pathogens to human. the genus-listeria has two pathogenic species namely, l. monocytogenes and l. ivanovii. l. monocytogenes is a well-known cause of abortion, encephalitis and septicaemia in man and animals. l. ivanovii is an animal pathogen and in rare cases cause huma...
