Physical Characterization of the PRRSV Virion
March 23, 2007By Michael Murtaugh
The research here shows that PRRSV grows in cells as a population of viruses with the same shape, the same RNA molecules, and the same protein composition. There was no evidence for multiple forms...

Quantitative evaluation of selective factors impacting the development, amplification, persistence and transfer of macrolide resistance elements within mixed populations of commensal and pathogenic gut bacteria.
February 28, 2007By Robin C. Anderson
A series of laboratory experiments were conducted to assess the effects of low (25 ug/ml) or high (100 ug/ml) tylosin treatment on potential development, amplification, persistance and transfer of...
