Tylosin was fed to two of six wethers for 79 days, to a second two for only 28 days, and not at all to a third pair (controls). The addition of tylosin to the daily feed resulted in a rapid twofold increase in protozoal concentration and a change in the composition or characteristics, or both, of the bacterial population. The results indicate that the bacterial population was modified to the ex...

In summary, in order to control tuberculosis, we require a rapid diagnosis of TB patients, who act as the source of disease; and if remain untreated, these patients can spread the disease throughout the population.

A fundamental property of cortical neurons is the capacity to exhibit adaptive changes or plasticity. Whether adaptive changes in cortical responses are accompanied by changes in synchrony between individual neurons and local population activity in sensory cortex is unclear. This issue is important as synchronized neural activity is hypothesized to play an important role in propagating informat...
