Rectal carriage of enterohemorrhagic Escherichia coli O157 in slaughtered cattle

Article Abstract:

A study was conducted aiming to compare in animals at slaughter the Escherichia coli O157 numbers at two mucosal sites that were 1 and 15 cm proximal to the recto-anal junction (RAJ) and to examine the relationship between mucosal carriage at these sites and fecal shedding of the organism. High-level carriage was detected in 3.7% of the animals, and carriage on the mucosal surface of the terminal rectum was associated with high-level fecal excretion.

Impact of the direct application of therapeutic agents to the terminal recta of experimentally colonized calves on Escherichia coli 0157:H7 shedding

Article Abstract:

A novel experimental method, based on the terminal-rectum-restricted colonization to eliminate fecal carriage of Escherichia coli 0157:H7 and reduce its prevalence within Escherichia coli and risk of infection to human is described.

Shedding of Escherichia coli O157:H7 in calves is reduced by prior colonization with the homologous strain

Article Abstract:

The prior colonization of enterohemmorrhaige Escherichia coli O157:H7 is found to induce humoral immune responses to the bacterial antigens. It also helps in reducing bacterial shedding in calves with a homologous strain.
