Bd is a very important chytrid fungus because it appears to be capable of infecting most of the worldâs approximately 6,000 amphibian species and many of those species develop the disease chytridiomycosis which is linked to devastating population declines and species extinctions (Berger et al., 1998; Skerratt et al., 2007; Fisher et al., 2009).
Because viruses, bacteria, and fungi cause many well-known diseases, it is common to confuse them, but they are as different as a mouse and an elephant. A look at the size, structure, reproduction, hosts, and diseases caused by each will shed some light on the important differences between these germs.udding occurs in yeasts, which are only made up of one cell. Budding is somewhat similar to binary fission in bacteria, in that the single cell divides into two separate cells. Fragmentation is a mode of reproduction used by those fungi that form hyphae.
