Harmful bacteria that cause bacterial infections and disease are called pathogenic bacteria. Bacterial diseases occur when pathogenic bacteria get into the body and begin to reproduce and crowd out healthy bacteria, or to grow in tissues that are normally sterile.armful bacteria may also emit toxins that damage the body. Common pathogenic bacteria and the types of bacterial diseases they cause include: Escherichia coli and Salmonella cause food poisoning. Helicobacter pylori cause gastritis and ulcers. Neisseria gonorrhoeae causes the sexually transmitted disease gonorrhea.
The discipline of biology devoted to the study of fungi is known as mycology, which is often regarded as a branch of botany, even though genetic studies have shown that fungi are more closely related to animals than to plants. Pathogenic fungi are fungi that cause disease in humans or other organisms.The study of pathogenic fungi is referred to as medical mycology. Although fungi are eukaryotic organisms, many pathogenic fungi are also microorganisms.Figure 1. A budding yeast: the Circular bud scars seen on the surface of the cell on the right represent sites of previous budding.ungi are classified as a kingdom that is separate from plants, animals, and bacteria. One major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants, which contain cellulose.
