| Summary |
Use of antibiotics in cattle may act as a selective pressure to increase the relative number of soil bacteria isolates resistant to the antibiotic drugs. On the other hand, soil bacteria are exposed to antibiotics synthesized by other soil bacteria. It may be that the effect of antibiotics entering the soil through cattle is inconsequential because of natural exposure to antibiotics. To determine the relative importance of the presence of cattle, soil from two adjacent areas occupied by cattle given antibiotics during calving and intermittently at other times was collected aseptically. Bacteria were isolated and tested against a panel of antibiotics using antibiotic discs on appropriate agar media. Diameter of the zone of inhibition was recorded. Soil from a site which had been free of cattle for more than ten years was similarly processed. Patterns of resistance from these sites are compared with data from samples from the Bighorn Mountains obtained last summer.
