Diversity and toxigenicity among members of the Bacillus cereus group

El género Bacillus como agente de control biológico y sus implicaciones en la bioseguridad agrícola

“…B. weihenstephanensis, some strains have been identified as pathogens for humans (Ceuppens et al, 2013;. Among these, B. cereus has been identified in a large diversity of foods (dairy products, fresh vegetables and others), causing important worldwide epidemiological crises, and in some cases, even death by emetic and diarrheal infections (Oh et al, 2012;Glasset et al, 2016). Also, B. thuringiensis strains have recently been related to intoxications caused by the ingestion of contaminated foods (Oh et al, 2012).…”

Also, B. thuringiensis strains have recently been related to intoxications caused by the ingestion of contaminated foods (Oh et al, 2012). The virulence of these species has been mainly related to the presence of two toxins, hemolysin BL (HBL) and the nonhemolytic enteric toxin (NHE), which form a protein complex .…”

“…Entre éstos, B. cereus se ha identificado en una gran diversidad de alimentos (productos lácticos, vegetales frescos, entre otros), provocando crisis epidemiológicas importantes a nivel mundial, y en algunos casos hasta la muerte, debido a infecciones eméticas y diarreicas (Oh et al, 2012;Glasset et al, 2016). Además, recientemente, cepas de B. thuringiensis han sido asociados a intoxicaciones por el consumo de alimentos contaminados (Oh et al, 2012).…”

Bacillus cereus un patógeno importante en el control microbiológico de los alimentos

“…Las enzimas utilizadas para la digestión del adn amplificado del gen gyrB fueron RsaI, Sau3AI y EcoRI [70]. Adicionalmente, el método de adn polimórfico amplificado aleatoriamente (Random Amplified Polymorphic dna-rapd), ha sido empleado con el fin de definir la diversidad genotípica de miembros del grupo Bacillus cereus obtenidos de muestras de arroz crudo y cocido en Australia [71].…”

“…They are also responsible for food spoilage and human and animal diseases (Logan, 2012). The Bacillus cereus group (B. cereus, Bacillus anthracis, Bacillus mycoides, Bacillus thuringiensis, Bacillus pseudomycoides, Bacillus weihenstephanensis, and Bacillus medusa) is known human pathogens; however, several other enterotoxin-producing bacilli are of major public health concern including Bacillus subtilis (From et al, 2005;Oh et al, 2012;Rasko et al, 2005). In this group, B. anthracis is the most virulent and the only pathogen that causes anthrax (Pilo and Frey, 2011).…”
