What are bacterial diseases?
bacterial diseases are infectious diseases affecting people that are caused by human pathogenic bacteria. Most bacteria are harmless to people and some are actually quite beneficial. However, some may cause illness and several of them are quite deadly. Many bacterial diseases can be successfully treated with modern antibiotics, although excessive use of these drugs is becoming increasingly a problem. Thanks to a bacterium called Mycobacterium tuberculosis , these diseases are responsible for the death of nearly 2 million people per year, mostly affecting the populations in the sub -Saharan region of the African continent. Pathogenic bacteria are the cause of infectious diseases including leprosy, tetanus, syphilis and typhoid. Diseases transmitted by bacteria with food consumption are Salmonella and Shigella.
Staphylococcus , whose primary pathogenic species is Staphylococcus aureus is the cause of most of the infections gained in the hospital. Trunks resistant to more medicines are going to beDEM to overuse antibiotics has become more and more problematic. Streptococcus pyogenes are bacteria that cause the throat, although not all streptococci are harmful. Some are beneficial, such as Streptococcus thermophilus , which is one of the bacteria that helps produce milk yogurt.
pathogenic bacteria can be sub-clasified with regard to how they interact with the infected person. Conditionally pathogenic bacteria are part of normal human flora and usually coexistens peacefully without causing any disease. However, these same organisms may cause pneumonia and meningitis in some individuals.
rickettsia is considered an intracellular pathogenic bacteria because it is only able to live in cells of the Ahostatean organism. Rocky Mountain Spotted Fever and Typehus are caused by another type of rickettsia . The third class of pathogenic bacteria is called opportunistic pathogen. These cause the disease especially in people with compromised immunosuppressive systems such as AIDS and cancer patients undergoing chemotherapy.
Antibiotics are used to treat people infected with bacterial diseases. There are two general types of antibiotics: bacteriocidals kill bacteria and bacteriostatics simply prevent the growth of bacteria. In addition to the treatment of diseases in humans, antibiotics are also used to promote agricultural animals. In recent years, it has been overuse of antibiotics in these two ways that many scientists have claimed that they have caused increasing resistance to antibiotics in the general population.
There are many simple methods to prevent infections caused by pathogenic bacterial diseases. By cooking food at least 140 degrees Fahrenheit (60 degrees Celsius), most bacteria transmitted by food can be killed. Correctly cleaning tools and cooking surfaces andSurfaces, especially cutting plates, can also help minimize risk. Proper sterilization of medical equipment, such as syringes, catheters and surgical tools, are important measures that can be taken to prevent bacterial infection.
