...ual taste neurons by inserting genes that produced diphtheria toxin. Each taste bristle hosts two to four taste neurons and one neuron that detects movement (a mechanosensory neuron). Typically, one of the taste neurons expresses receptors from the set of six, while another neuron expresses the lone receptor fr...Pacifying bacteria prevents lethal post-op infections
...cs and it secretes toxins similar to those used by diphtheria or anthrax. "This is the most lethal of the opportunistic pathogens," he adds. "Patients with widespread Pseudomonas infection can die in a matter of days." A coating with a high molecular weight polymer however, can form a surrogate bioshield, mu...R.

...tain bacteria such as those causing scarlet fever, diphtheria and E. coli O157 (a source of food poisoning in contaminated meats) as toxigenic, meaning that these microbes produce toxins -- transported by phage -- that cause disease.

...ad a major drawback: in most cases, they came from diphtheria and tetanusbacteria and, as a result, they tended to triggerthe production of antibodies against themselves, a process which interferes withthe creation of the antibodies needed to prevent the disease.

Originally isolated in 1922 from a convalescent diphtheria patient, the strainof E. coli sequenced by Blattner's team rose to prominence as an experimental organism in 1945 when it was used in the discovery of spontaneous gene transfer or bacterial sex. As a result, the strain, known as K-12, was universally...
