The New Diarrheas.

The article explores emerging biological diseases that will challenge the public health community. The fecal flora derives from enteric bacterial, which are organisms that inhabit intestinal tracts of humans and animals. A gram of adult human feces can contain astronomical numbers of bacterial cells. The planet's aquatic systems have been forced to accommodate quantities of bacterial organisms as a consequence of the growth of human population and the rise in the deposition of fecal material into surface waters. The advent of molecular biology-based protocols and tools has revolutionized knowledge of viral participation in the ecosystems. The importance of viruses lies in their ability to move genes.
