Mastitis, an inflammatory reaction of the mammary gland, usually resulting from a microbial infection, is a widespread disease seen in cattle throughout the world. The major bacterial species that are responsible for bovine mastitis are Staphylococcus aureus. Streptococcus dysgalactiae, Streptococcus agalactiae, Streptococcus uberis, and E. coli. Of these, the first three cause a contagious route of transmission, whereas Streptococcus uberis and...

Nisin belongs to a group of bactericidal peptides called type A lantibiotics (Willey and van der Donk, 2007). Four natural nisin variants (A, Z, Q, and U) have been discovered. Nisins A, Z, and Q are produced by L. lactis while nisin U is produced by Streptococcus uberis. Two main variants of nisin A and Z have been described (De Vuyst and Vandamme, 1994). Nisin Z is widely distributed and contains asparagine instead of histidine at position 27 of the amino acid sequence of nisin A (Fig. 11.2). The two variants have nearly equal bactericidal activity, membrane insertion, and pore-forming ability.
