You isolate a bacterium from several patients that seems like a good candidate for the pathogen. How can you determine if this bacterium is causing the illness?
I would investigate the bacteria to determine if it had genetic markers consistent with known disease-causing bacteria. I would first prescribe antibiotics to patients and if this cleared up the respiratory ailments then I would assume this bacteria is the cause of the disease.
As a U.S. Department of Agriculture field representative, you counsel a young farmer to plant alfalfa in fields with soils that have low nitrogen levels. You know alfalfa can host certain bacteria.
a. Explain your reasoning.
The growth of alfalfa will ultimately improve the soil, adding much-needed nitrogen and producing a better harvest.

No medical treatment exists for treating HPV infection other than prevention through education about the dangers of multiple sexual partners and unprotected sex, because HPV infection is transmitted through sexual contact with an infected individual. A vaccine is available, but both its high cost and several elements associated with its rushed approval by the FDA in 2006 suggest that further study is warranted before its wide-scale use, particularly on a mandatory

Disease Trends in the United States Aging About 4.5% of the world's population comprises of the people of United States (U.S.). The country has the world's third largest population and statistical analysis shows that approximately 155 million people have been added to the U.S. population and figures have increased by nearly 105% in the past 50 years (Kotkin, 2010). In addition, the U.S. population has also experienced a qualitative change. According to
It ranges from 31.9% in the mid-Atlantic to 67.2% in the south Atlantic regions. The increased occurrence also varies considerably by state ranging from 11.3% in Delaware to 101.8% for Georgia. Other studies have shown that the magnitude of the increase is greatest in 18 to 29-year-olds, those with some college education and those of Hispanic ethnicity (Lifestyle Management of Adult Obesity, 2010). The yearly economic costs of obesity are
