MASTITIS
ORGANISMS
[Vol. XXVIII, Part II,
elimination of organisms was followed by fall in the number of leucocytes per ml. of
milk to the normal range. The results indicate that Staph. albus, under certain
circumstances, is capable of setting up inflammatory changes in the infected quarter.
SUMMARY
Twenty quarters in preclinical stage of mastitis were treated with terramycin,
animal formula for mastitis given 426 mg. of oxytetracycline and 142,000 units of
polymyxin β sulfate intramammarily, daily for three consecutive days.
Mastitic udders with a capacity of 10 to 15 lb. in the preclinical and clinical
stage of the disease due to Staphylococcus aureus and albus sensitive to a combina
tion of 0.03 mg. of oxytetracycline and 10 units of polymyxin β sulfate or lesser
concentration were cured for all clinical and bacteriological purposes.
Streptococcus pyogenes and Str. uberis cases taken up in this study did not give
encouraging results.
The importance of leucocytic count as a pointer towards the recovery or other
wise is discussed.
The capacity of Staph. albus to set up inflammatory changes has also been taken
into account.
