Antibiotic-Resistance of Coagulase Positive Staphylococci Isolated from Various Animals

Antibiotic-resistance of coagulase positive staphylococci isolated from various animals including human was tested by disc method“Eiken”. Of the six kinds of antibiotics tested PC, TC and SM were relatively resistant, but EM, CM and KM were fairly sensitive. Multiple antibiotic-resistances were seen in these strains isolated from dogs (4 antibiotics), human (4 antibiotics), fowls (3 antibiotics), bovine (2 antibiotics) and pigs (2 antibiotics). After all the resistant strains ratios to each host-derived strains tested were as follows: human (91 strains of 100 strains, 91%), pigs (19 strains of 23 strains, 83%), fowls (59 strains of 100 strains, 59%), bovine (26 strains of 100 strains, 26%), dogs (39 strains of 160 strains, 24%), horses (1 strain of 55 strains, 2%).
