Comparable stx 2a expression and phage production levels between Shiga toxin‐producing Escherichia coli strains from human and bovine origin

Autor: Alejandra Krüger, Julia Burgán, Paula Maria Alejandra Lucchesi

Publikováno v: Zoonoses and Public Health. 67:44-53

Shiga toxin-producing Escherichia coli (STEC) can cause diarrhea and severe diseases in humans such as hemolytic uremic syndrome. Shiga toxins (Stx) are encoded in prophages which play an important role in STEC pathogenesis. The pathogenic potential

Subtypes of NanS-p Sialate O-Acetylesterase Encoded by Stx2a Bacteriophages

Autor: Paula Maria Alejandra Lucchesi, Stefanía B. Pascal, Juan R. Lorenzo Lopez, Alejandra Krüger

Publikováno v: Proceedings, Vol 66, Iss 15, p 15 (2020)

Shiga toxin (Stx)-producing Escherichia coli strains are foodborne pathogens that can cause severe human diseases, such as haemorrhagic colitis and haemolytic uraemic syndrome. Stxs are encoded by bacteriophages (Stx phages) which show remarkable var

Comparison of 2 proposed MLVA protocols for subtyping non-O157:H7 verotoxigenic Escherichia coli

Autor: Andrea Mariel Sanso, Ana Victoria Bustamante, Juliana González, Paula Maria Alejandra Lucchesi

Publikováno v: Diagnostic Microbiology and Infectious Disease. 78:328-332

Multiple locus variable number tandem repeats (VNTRs) analysis (MLVA) has become a reliable tool, able to establish genetic relationships for epidemiological surveillance and molecular subtyping of pathogens such as verotoxigenic Escherichia coli (VT
