Clostridium perfringens epsilon toxin induces permanent neuronal degeneration and behavioral changes
(2017-05)Clostridium perfringens epsilon toxin (ETX), the most potent toxin produced by this bacteria, plays a key role in the pathogenesis of enterotoxaemia in ruminants, causing brain edema and encephalomalacia. Studies of animals ... -
Comprehensive assessment of water quality through different approaches: Physicochemical and ecotoxicological parameters
(Elsevier, 2021-08-03)Traditionally, water quality was assessed by physicochemical parameters. However, a more comprehensive analysis is needed to study the effects of polluted water bodies on key species over time. So, the aim of this study ... -
Effects of Clostridium perfringens iota toxin in the small intestine of mice
(2017-12)Iota toxin is a binary toxin solely produced by Clostridium perfringens type E strains, and is structurally related to CDT from C. difficile and CST from C. spiroforme. As type E causes hemorrhagic enteritis in cattle, it ... -
Identification of the gamma irradiation dose applied to ground beef that reduces Shiga toxin producing Escherichia coli but has no impact on consumer acceptance
(Elsevier, 2020-11-18)The aims of the present study were: a) to estimate the minimal dose of gamma irradiation required to reduce 5 log CFU/g of native O157 and non-O157 Shiga toxin-producing Escherichia coli population in ground beef samples ... -
Inactivation of Shiga toxin-producing Escherichia coli in fresh beef by electrolytically-generated hypochlorous acid, peroxyacetic acid, lactic acid and caprylic acid
(Elsevier, 2019-07-05)Several studies have been conducted to verify the decontamination potential of electrolyticallygenerated hypochlorous acid, peroxyacetic acid, lactic acid and caprylic acid against Shiga toxin-producing Escherichia coli ... -
Risk factors for shiga toxin-producing Escherichia coli-associated human diseases
(American Society for Microbiology, 2014)We have reviewed the risk factors for the occurrence of Shiga toxin-producing Escherichia coli (STEC)-associated human diseases. The analysis of STEC surveillance data and trends shows differences in frequency and severity ... -
Rol de las toxinas binarias en las enfermedades intestinales causadas por clostridios enterotóxicos
(Facultad de Farmacia y Bioquímica, Universidad de Buenos Aires, 2015-03)Las enfermedades digestivas causadas por especies del genero Clostridium poseen un importante impacto en la medicina tanto humana como veterinaria. Entre las especies patógenas más importantes de este género se encuentran ... -
Validación de irradiación para reducir la presencia de Escherichia coli productor de toxina Shiga en carne picada fresca.
(2019-09)Escherichia coli productor de toxina Shiga (STEC) es el agente causal de diarreas con o sin sangre y, en los casos más severos, del Síndrome Urémico Hemolítico. La carne picada ha sido descripta como uno de los principales ...
