Most bacteria do not cause any harm to people.

Bacterial against viral infections: How are they different? What is the difference between bacterial infections and viral infections? from James M. Steckelberg, MD What do you think of bacterial infections caused by bacteria and viral infections caused by viruses. Infections caused by bacteria include strep throat, tuberculosis and urinary tract infection. Diseases which result include chicken pox virus, AIDS and cold. Bacteria are unicellular microorganisms that thrive in different types of environments. Some species live in extreme cold or heat, while others make their home in the intestines of people, where they help digest food. Most bacteria do not cause any harm to people. Viruses are even smaller than bacteria and require a living host, such as people, plants or animals reproduce. Otherwise, they can not survive. When the virus enters your strattera dosing body, it invades some of your cells and takes over the cell machinery, redirecting it to get the virus. Perhaps the most important difference between bacteria and viruses that antibiotics usually kill bacteria, but they are not effective against viruses. In some cases it may be difficult to determine whether a bacterium or virus is causing your symptoms. Many diseases such as pneumonia, meningitis and diarrhea may be caused by any type of microbe. Misuse of antibiotics has helped to create strains of bacterial infections resistant to antibiotic treatment of various types of medicines. E. coli: How can I tell if food is contaminated? .
