Cell-Mediated Immunity Definition CMI is an unique sort of acquired immune response that is not mediated by antibodies but rather by sensitised T cells. This type of immunity is passed from donor to recipient without the need of antisera, but rather with intact lymphocytes; therefore, it is referred to as cell-mediated immune reaction. Contrary to … Read more

Chytridiomycota is a sub-group of zoosporic organisms from the kingdom Fungi. They are also known as chytrids. Named after the Ancient Greek word khutridion, which means “little pot”, it refers to the structure that contains unreleased zoospores. The earliest diverging fungal lineages are the Chytrids. Their membership in kingdom Fungi can be seen with chitin cell wall, posterior whiplash flagellum and absorptive nutrition. They also use glycogen to store energy and produce lysine through the a-amino acid (AAA).
