Causes of an abscess. Most abscesses are caused by a bacterial infection. However, they can very occasionally develop due to an infection by viruses, fungi or parasites.When foreign organisms such as bacteria enter the body, the immune system sends white blood cells to fight the infection.he abscess may get larger and more painful as the infection continues and more pus is produced. Most abscesses occur as a result of staphylococcal bacteria and streptococcal bacteria. Some types of staphylococcal bacteria produce a toxin called Panton-Valentine leukocidin (PVL), which kills white blood cells.
