However, incidents of apnea followed by awakening can occur hundreds of times during the night, significantly reducing sleep time. Furthermore, drinking moderate to high amounts of alcohol prior to sleep can narrow the air passage, causing episodes of apnea in persons who normally do not exhibit sleep apnea symptoms.
The vast majority of the bacteria in the body are rendered harmless by the protective effects of the immune system, and some are beneficial. However, several species of bacteria are pathogenic and cause infectious diseases, including cholera, syphilis, anthrax, leprosy, and bubonic plague.he word bacteria is the plural of the New Latin bacterium, which is the latinisation of the Greek Î²Î±ÎºÏÎ®ÏÎ¹Î¿Î½ (bakterion), the diminutive of Î²Î±ÎºÏÎ·ÏÎ¯Î± (bakteria), meaning staff, cane, because the first ones to be discovered were rod-shaped.
What is Tuberculosis? Tuberculosis is an infectious disease of humans and animals. The most common cause of human disease is the bacteria (mycobacteria) called Mycobacterium tuberculosis (M. tuberculosis). In 1995, almost 23,000 human cases were reported to the Centers for Disease Control and Prevention (CDC).ther mycobacteria that cause human diseases are very rare in people with healthy immune systems. Tuberculosis in humans is commonly seen as a lung infection or pneumonia. While infection of other organs such as the brain, bones, intestines, and kidneys also occurs, these are rare.
