Although the exact pathogenic species vary with the infected species, bacteria, fungi, viruses, nematodes, and insects can all cause plant disease. As with animals, plants attacked by insects or other pathogens use a set of complex metabolic responses that lead to the formation of defensive chemical compounds that fight infection or make the ...
Neutrophil ingesting Methicillin-resistant Staphylococcus aureus (MRSA). Neutrophils are some of the first immune cells to travel to sites of infection that aid in fighting infection by ingesting microorganisms and providing the enzymes to kill them. This process characterizes neutrophils as a type of phagocyte. [8]
Neutrophils travel across epithelial cell-lined organs to sites of infection, and although this is an important component of fighting infection, the migration itself can result in disease-like symptoms. [68] During an infection, millions of neutrophils are recruited from the blood, but they die after a few days. [69]
Neutrophils, macrophages, monocytes, dendritic cells, osteoclasts and eosinophils can be classified as professional phagocytes. [10] The first three have the greatest role in immune response to most infections. [11] The role of neutrophils is patrolling the bloodstream and rapid migration to the tissues in large numbers only in case of ...

Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
Plants are constantly exposed to different stresses that result in wounding. Plants have adapted to defend themselves against wounding events, like herbivore attacks or environmental stresses. [1] There are many defense mechanisms that plants rely on to help fight off pathogens and subsequent infections.
Plant diseases can also be partially controlled by use of pesticides and by cultivation practices such as crop rotation, tillage, planting density, disease-free seeds and cleaning of equipment, but plant varieties with inherent (genetically determined) disease resistance are generally preferred. [2]
