Antimicrobial susceptibility of streptococci from various indications of swine, horses, dogs and cats as determined in the BfT-GermVet monitoring program 2004-2006.
Abstract: A total of 500 streptococci from two indications of swine (beta-haemolytic streptococci from infections of the urinary/genital tract including strains from the mastitis metritis agalactia syndrome as well as S. suis from infections of the central nervous system and the musculoskeletal system), two indications of horses (S. equi from respiratory tract infections and beta-haemolytic streptococci from infections of the genital tract), as well as three indications of dogs and cats (beta-haemolytic streptococci from infections of the respiratory tract, the urinary/genital tract, and skin/ear/mouth) were investigated for their susceptibility to antimicrobial agents. Regardless of the animal origin and indication, the most frequently detected resistance properties were resistances against sulfamethoxazole (20-78%), tetracycline (17-93%) as well as gentamicin (14-79%). Resistance to penicillins or cephalosporins was very rarely detected - if at all.

A study was done to test the resistance of streptococci, a kind of bacteria, from urinary, genital, respiratory, and musculoskeletal infections in swine, horses, dogs, and cats to various antibacterial drugs. Veering towards resistance, the bacteria showed most frequent resistance against sulfamethoxazole, tetracycline, and gentamicin, but rarely to penicillins or cephalosporins.
Overview of Research
In response to the rise of antibiotic resistance in bacteria, this research examined the streptococci isolated from different types of infections in swine, horses, dogs, and cats. The susceptibility of these bacteria to different antimicrobial agents was tested to understand the prevalence of resistance.
- Bacteria from two indications (reasons) from each type of animals was taken: one from urinary or genital infection and the other from either respiratory, central nervous system or musculoskeletal infections.
- Overall, 500 streptococci were tested for their resistance to several antibacterials.
Findings of the Study
Resistance properties were identified in the bacteria, regardless of the animal from which it was isolated.
- The highest levels of resistance were found against three antibacterials: sulfamethoxazole, tetracycline, and gentamicin, with resistance rates ranging from 14% to 93%.
- Resistance to penicillins or cephalosporins, however, was either very rare or undetectable.
Implications of the Findings
The results of this study highlight the significant antibiotic resistance among streptococci, particularly to sulfamethoxazole, tetracycline, and gentamicin. This poses a concerning issue for treating infections caused by these bacteria in animals.
- The low resistance against penicillin and cephalosporins suggests these two could be more effective in treating infections caused by streptococci.
- Effective monitoring and control programs are crucial to prevent the further spread of antibiotic resistance.
