Geobacillus stearothermophilus V ubiE gene product is involved in the evolution of dimethyl telluride in Escherichia coli K-12 cultures amended with potassium tellurate but not with potassium tellurite.

J. Biol. Inorg. Chem. 9(5) , 609-15, (2004)

A 3.8-kb fragment of chromosomal DNA of Geobacillus stearothermophilus V cloned in pSP72 (p1VH) confers resistance to potassium tellurite (K(2)TeO(3)) and to potassium tellurate (K(2)TeO(4)) when the ...

Evaluation of culture methods to identify bovine feces with high concentrations of Escherichia coli O157.

Appl. Environ. Microbiol. 73(16) , 5253-60, (2007)

Our objective was to evaluate methods for identifying cattle with high concentrations of Escherichia coli O157 in their feces. In two experiments, feces were collected from cattle orally inoculated wi...

Expression of Aeromonas caviae ST pyruvate dehydrogenase complex components mediate tellurite resistance in Escherichia coli.

Biochem. Biophys. Res. Commun. 380(1) , 148-52, (2009)

Potassium tellurite (K(2)TeO(3)) is harmful to most organisms and specific mechanisms explaining its toxicity are not well known to date. We previously reported that the lpdA gene product of the tellu...
