    Macrophage engulfing TB bacteria. Computer illustration of a macrophage white blood cell (pink) engulfing tuberculosis (Mycobacterium tuberculosis) bacteria (orange). This process is called phagocytosis. Macrophages are cells of the body's immune system. They phagocytose and destroy pathogens, dead cells and cellular debris.

    Bacteria and yeast. Coloured scanning electron micrograph (SEM) of bacteria (red) and yeast. In many environments, bacteria and fungi coexist and interact. Furthermore, these bacterial-fungal interactions often have important ramifications for the biology of the interacting partners. In humans this coexistence in the human microbiome in health and during disease is of major research interest. Magn

    MRSA bacteria. Coloured scanning electron micrograph (SEM) of methicillin-resistant Staphylococcus aureus (MRSA) bacteria (round). MRSA is a Gram-positive, round (coccus) bacterium that is resistant to many commonly prescribed antibiotics. It is carried by around a third of the population without causing any symptoms. However, in vulnerable people, such as those that have recently had surgery, it

    Klebsiella pneumoniae bacteria in biofilm, computer illustration. K. pneumoniae are Gram-negative, encapsulated, non-motile, enteric, rod prokaryote. This species causes Friedlander's pneumonia and urinary tract infections. K. pneumoniae's pathogenicity can be attributed to its production of a heat-stable enterotoxin. This bacterium has antibiotic resistance properties. Klebsiella species may cont
