Many people think that a yellow or green nasal discharge means a bacterial infection, which requires antibiotics but it is not true. It can be a sign that your body is being attacked by either a bacteria or a virus. That said, a yellow discharge does not necessarily indicate a sinus infection.
After the stool is placed in the culture, it may take two to three days for any bacteria that is in the stool to grow. These bacteria can then be isolated and examined under a microscope so that they may be identified. The stool may also be tested for parasites or eggs.
How long does it take to have an empty stomache?   It usually takes about 4 to 6 hours for a full stomach to digest the food. However, this varies from person to person, and if vomitting occurs, much less time. It takes â¦from 12 to 24 hours for the food to completely leave the digestive/excremetory systems.
