Enterococci are part of the normal intestinal flora of humans and animals. They have been long recognized as important human pathogens and are becoming increasingly so. The genus Enterococcus includes more than 17 species, although only a few cause clinical infections in humans.nterococci are part of the normal intestinal flora of humans and animals.

Asthma (AZ-ma) is a chronic (long-term) lung disease that inflames and narrows the airways. Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning. Asthma affects people of all ages, but it most often starts during childhood.
Introduction. Asthma is a common long-term condition that can cause coughing, wheezing, chest tightness and breathlessness. The severity of these symptoms varies from person to person. Asthma can be controlled well in most people most of the time, although some people may have more persistent problems. Occasionally, asthma symptoms can get gradually or suddenly worse. This is known as an asthma attack, although doctors sometimes use the term exacerbation.
