**4.2 Contagious bovine pleuropneumonia**

Caused by *Mycoplasma mycoides* subsp. *Mycoides* (the bovine biotype). *Mycoplasma mycoides* are a small colony type, belonging to the *Mycoplasmataceae* family. It can be categorized into two major lineages [1–3]:

1.Isolates from Europe

2.Isolates from Africa

Other strains of *M. mycoides* were retrieved from other animal species (goats or sheep). The other strains are similar antigenically to bovine strains; they do not appear to be pathogenic to cattle, but they may cause diseases other than CBPP in small ruminants.
