ABSTRACT: Van Tonder E.M., Kellerman G.E., Bolton T.F.W. Discolouration of Wool: 1 Green Discolouration. Journal of the South African Veterinary Association (1974) 47 No.3 223-226 (En) Regional Veterinary Laboratory, Middleburg, 5900 Republic of South Africa.

 

Since 1974 green bacterial discolouration of Merino wool was frequently encountered in the Karoo and Eastern Cape areas. The occurrence of this condition coincided with the extraordinary wet conditions that prevailed during this period. Pseudomonas aeruginosa was recovered in almost pure culture from affected wool of 24 out of 25 different sheep. The role played by this particular organism was confirmed by the successful reproduction of this condition after exposure of unaffected sheep to cultures of Ps. aeruginosa isolated from green wool.
