BAL ARILARINDA SOSYAL VE BİREYSEL BAĞIŞIKLIK.

Honey bees play an important role in pollination in the natural ecosystem and agricultural field. Many biotic and abiotic stress factors such as pathogens (parasites, fungi, viruses and bacteria), ecosystem changes or losses, use of agricultural chemicals, alone or in combination, adversely affect the health and life of the bee colony. All these factors affect the immune system of the bees and change their defense mechanisms. Honey bees have a natural immune system consisting of physical barriers, generalized cellular and humoral immune response to protect themselves against infectious and parasitic agents. Pathogens, acaricides, fungicides, herbicides and other pesticides affect the bee immune system and hence bee health. Defense mechanisms of the bee immune system include signaling pathways, pathogen recognition receptors and innate immune system effectors. The risk of epidemic infection in honey bee colonies is reduced by individual and social immunity. Both types of immunity protect from diseases at various levels and play an important role in the formation of immune response against parasitic or other infectious diseases. [ABSTRACT FROM AUTHOR]
