The White Blood Count (WBC) is an important part of your body’s immune system. It is a measurement of the number of white blood cells in your blood. White blood cells are a type of immune cell that helps your body fight off infections and diseases. They are produced in the bone marrow and are released into the bloodstream.
A normal WBC count is usually between 4,500 and 11,000 cells per cubic millimeter of blood. If your WBC count is higher than normal, it may be a sign of an infection or inflammation in your body. Symptoms of a high WBC count can include fever, fatigue, and body aches.
On the other hand, a low WBC count can indicate a weakened immune system, usually due to certain medications or medical conditions. Neutrophils, a type of white blood cell, are often the first responders to an infection. They are specialized cells that can quickly move to the site of infection to destroy bacteria and other harmful substances.
Your doctor may order a WBC count as part of a routine blood test or if you are experiencing symptoms that suggest an infection or other medical condition. The test is performed by taking a small sample of blood from a vein in your arm using a needle.
Treatment for a high or low WBC count will depend on the underlying cause. If an infection is present, your doctor may prescribe antibiotics to help kill the bacteria. In some cases, chemotherapy may be necessary to reduce the number of abnormal white blood cells. It is important to discuss treatment options with your doctor to determine the best course of action.
In conclusion, the WBC count is an important diagnostic tool that helps doctors identify infections, diseases, and other disorders in the body. Having a high or low WBC count can indicate an underlying problem that needs further investigation and treatment. Regular blood tests and proper medical care are essential to maintaining a healthy immune system and preventing further damage to your body.

Australian National Genomic Information Service (ANGIS), including the database of BioManager, has been maintained for a long time by Peter Reeves, a professor at the University of Sydney.
Professor Reeves is internationally renowned for his genetic analysis of enteric bacteria. He determined the genetic basis of the enormous variation in O antigens. There can be more than an I00 form within a species and little overlap between related species. This variation is due to the reassortment of genes between O antigen genes and other gene clusters and the transfer of gene clusters between species. He showed that the 7th pandemic clone of Vibrio cholerae did not arise directly from the 6th pandemic clone, suggesting it arose from an environmental strain, with implications for the origins of this significant human pathogen.
