The antibiotic resistant faecal flora of a domestic dog suffering from an acute enteric infection was examined. The flora exhibited overall resistance to a wide variety of antibiotics. However, following restoration of the animal to normal health, overall resistance to ampicillin (Ap), tetracycline (Tc), chloramphenicol (Cm) and streptomycin Sm was lost, although low numbers of bacteria resistant to these four antimicrobial agents could still be isolated up to one year later. A total of 11 strains were purified for further study. All 11 were positively identified as Escherichia coli and shown to be resistant to various combinations of the above antibiotics, and additionally to kanamycin (Km). Each strain harboured from one to five plasmids, although only four proved capable of transferring antibiotic resistance to Escherichia coli K-12. One of the strains was found to harbour two conjugal plasmids pNJ101 (60 Md) and pNJ102 (133 Md) which coded for resistance to Cm, Tc, Ap and Cm, Tc, Km respectively. A third plasmid pNJ103 (29 Md) remains cryptic. The possession of the two plasmids pNJ101 and pNJ102 appears to be an unstable situation as variants arose harbouring one or other of the plasmids.

“…In our study, the level of resistance was low in canine enterococci and E. coli isolates. [17] investigated E. coli strains from healthy urban and rural dogs and observed more multiresistance in E. coli isolates from rural dogs living on dairy farms than in E. coli isolates from urban dogs. These dogs had not received antimicrobials, but the selection pressure was supposed to be derived from antimicrobials used for cows.…”

“…Monitoring programmes for antimicrobial resistance have been established in veterinary medicine, but only for food producing animals [15]. Not many reports of the level of antimicrobial resistance in canine normal flora have been published [8,17,5,26]. The aim of this study was to investigate whether the bacteria of the normal flora are more resistant in dogs, which have received antimicrobials for the treatment of chronic dermatological disorders, when compared to the bacteria of non-treated control dogs.…”

Rantala M, Lahti E, Kuhalampi J, Pesonen S, Järvinen A-K, Saijonmaa-Koulumies L, Honkanen-Buzalski T: Antimicrobial resistance in Staphylococcus spp., Escherichia coli and Enterococcus spp. in dogs given antibiotics for chronic dermatological disorders, compared with non-treated control dogs. Acta vet. scand. 2004, 45, 37-45. -The aim of this study was to evaluate antimicrobial resistance in canine staphylococci, Escherichia coli and enterococci, which were isolated from 22 dogs with pyoderma and a history of previous antibiotic treatment, compared to bacterial isolates from 56 non-treated control dogs. Two isolates of each bacterial species per dog were investigated, if detected. Staphylococcal isolates from dogs with pyoderma (35 isolates) were more resistant to sulphatrimethoprim than the isolates from controls (56 isolates) (57% vs. 25%, p<0.004). Multiresistance in staphylococci was also more common in dogs with pyoderma (29% vs. 9%, p=0.02). A similar trend among isolates of E. coli was detected (24 and 74 isolates from treated and control dogs, respectively), but the differences were not significant. Resistance for macrolide-lincosamides was approximately 20% among staphylococci in both groups. Resistance to ampicillin among enterococci was 4%-7%. The age of the dogs might have an impact on resistance: multiresistance among staphylococcal isolates from younger dogs (≤5 years) was more common than in older dogs (≥6 years) (24%, vs. 0%, 63 and 27 isolates, respectively, p=0.02). Staphylococci in younger dogs were more resistant to tetracycline (48% vs. 11%, p<0.001) and sulphatrimethoprim (48% vs. 15%, p<0.01) than those in older dogs. In contrast, the isolates of E. coli from older dogs tended to be more resistant, although a significant difference was detected only in resistance to tetracycline (13% vs. 2% of 40 and 50 isolates respecthely, p=0.04)). The results of this small study indicate that resistance in canine staphylococci in the capital area of Finland is comparable with many other countries in Europe. Resistance in indicator bacteria, E. coli and enterococci, was low.antimicrobial resistance; normal flora; Staphylococcus spp.; Enterococcus faecalis; Enterococcus faecium; Escherichia coli; pyoderma; dog.

“…Household pets associating with man, or other animals o n medication, either companion animals undergoing therapy or food animals being given drugs for growth promotion or therapy, could therefore be exposed to crossinfection (Hirsh er al 1980). Rural dogs from dairy farms have been shown to carry exceptionally high levels of multiresistant faecal coliform bacteria in comparison to dogs sampled from tillage farms (Monaghan et a / 1981). The use of commercial dog and cat foods containing antibiotic residues may also contribute to the selective pressure.…”

The prevalence of antibiotic resistant Escherichia coli in the rectal flora of 168 healthy dogs and 93 cats in the Brisbane area was investigated. Rectal swabs were plated on MacConkey agar with and without antibiotics, and 690 isolates confirmed as faecal E. coli were tested for resistance to tetracycline, streptomycin, chloramphenicol, ampicillin, neomycin, furazolidone and sulphanilamide. Resistant isolates were obtained from 101 (60%) of the dogs and 24 (26%) of the cats sampled. A high percentage of the isolates was resistant to tetracycline, streptomycin, ampicillin and sulphanilamide. Multiple resistance to 3 or more of the drugs was exhibited by the majority of isolates and a total of 31 different multiple resistance patterns was demonstrated. Of the 50 strains tested for transfer of resistance, 30 (60%) transferred some or all of their resistance determinants to an E. coli K12F - recipient.
