“…It is discussed here because many strains will eventually grow in ambient air, and because Rothia dentocariosa may appear as a rod. Experience in the therapy of infections caused by the first two genera is more extensive than with the others [25–32]. Thus far, all genera have remained susceptible to penicillin and other β‐lactam antibiotics [25–32], penicillin being the drug of choice.…”

This review presents data on in vitro susceptibilities of aerobically growing Gram-positive rods and in vivo activities of antibiotics used against Gram-positive rods. While in some instances susceptibility and efficacy are predictable (e.g. penicillin vs. Listeria and microaerophilic coryneforms, or metronidazole vs. Gardnerella) susceptibility testing by dilution techniques seems necessary for many Gram-positive rods as long as they are deemed clinically relevant.

“…5,6,10,14,31 Nevertheless, the study evaluated A. pyogenes isolated from various lesions of necrobacillosis but did not involve a single strain of A. pyogenes isolated from deer lung. 5 All A. pyogenes isolates tested were highly susceptible to ceftiofur, spectinomycin, tiamulin, and trimethoprimsulfamethoxazole, suggesting their potential use in treating A. pyogenes-associated pneumonia.…”

Antimicrobial susceptibility ofArcanobacterium pyogenesisolated from the lungs of white-tailed deer (Odocoileus virginianus) with pneumonia

Abstract. In vitro susceptibilities of 29 strains of Arcanobacterium pyogenes isolated from lung lesions of white-tailed deer (Odocoileus virginianus) with pneumonia were determined using the broth microdilution method to ascertain efficacious treatment options for pneumonic white-tailed deer. All 29 A. pyogenes strains tested were susceptible to ceftiofur, spectinomycin, tiamulin, and trimethoprim-sulfamethoxazole but were resistant to both danofloxacin and sulfadimethoxine. Likewise, all 29 isolates were either fully susceptible or intermediately susceptible to gentamicin (25 susceptible; 4 intermediate) and tulathromycin (25 susceptible; 4 intermediate). At least one isolate of A. pyogenes tested was resistant to ampicillin, chlortetracycline, clindamycin, enrofloxacin, florfenicol, oxytetracycline, penicillin, and tilmicosin suggesting their ineffectiveness in treating A. pyogenes-associated lung infections in white-tailed deer. Minimum inhibitory concentration (MIC) data for tylosin and neomycin could not be interpreted due to unavailability of Clinical and Laboratory Standards Institute (CLSI)-approved breakpoints for these 2 agents. In summary, based on MIC values, ceftiofur, spectinomycin, tiamulin, and trimethoprimsulfamethoxazole are more efficacious than other antimicrobial agents for treating A. pyogenes-related pneumonia in whitetailed deer. However, ceftiofur may be preferred over the other 4 drugs as it is being widely used to treat respiratory disease in cattle and other animal species, as well as is available for single dose parenteral administration.
