While bacteria might appear to be very simple when viewed from a strictly biological perspective, they are able to form intricate associations with more complex organisms. One such association is referred to as parasitism, a type of symbiotic relationship in which the bacteria benefit at the cost of the host organism. Bacteria that play the role of parasites are called pathogens and they are a major cause of disease and death in the human population. Some of the diseases caused by pathogenic bacteria include syphilis, pneumonia, cholera, meningitis, gonorrhea, heart infections, kidney disease, skin infections and foodborne illnesses, among many other ailments. Despite the health risks posed by these imperceptible microbes, research has shown that a big bunch of tasty grapes can go a long way towards stopping them.
