Association between hemolytic activity on rabbit RBC and biofilm formation activity in Staphylococcus intermedius isolates from dogs and pigeons
Hemolytic activity on Rabbit RBC | Animal (no. of isolates) | Biofilm formation activityc (absorbance value at 490 nm) | |
Range | Mean | ||
Positivea | Dogs (43) | 0.02–1.00 | 0.48d |
Pigeons (11) | 0.22–0.71 | 0.52d,e | |
Total | (54) | 0.02–1.00 | 0.49f |
Negativeb | Dogs (1) | 0.71 | 0.71 |
Pigeons (51) | 0.04–0.79 | 0.28e | |
Total | (52) | 0.04–0.79 | 0.29f |
