A senior British government veterinarian stated in 1962 (3)> When penicillin was first used in treating mastitis only 2% of the strains of staphylococci recovered from cases of mastitis were resistant to penicillin. Today the figure is over 70%. Between 1958 and 1961, resistance to penicillin (PEN) increased from 62.0% to 70.6%. Resistance to streptomycin (STR), tetracycline and chloramphenicol also increased (. Antibiotic resistance increased for isolates of both mastitis staphylococci and streptococci in Canada between I960 and 1967 (5). In Belgium (6), Staphylococcus aureus strains isolated from cases of bovine mastitis showed increase in PEN resistance from 38% in 1971 to 78% in 1974> but then no further increase to 1980. The resistance situation was reported to remain stable in the Federal Republic of Germany between 1962 and 1975 (7), as also in Australia between 1974 and 1979 (8 ) and Denmark, at a very low level, for the period 1963 to 1978 (9). 

Most states appear with less than 3 per cent of the forested area damaged. A greater percentage has been reported by the government of Norway and Sweden (5%), Austria (6%), Poland (7%), Federal Republic of Germany (8%), Czechoslovakia (10%), and German Democratic Republic (12%).
