Isolation and species identification of Campylobacter spp. from healthy and diarrheic dogs
Campylobacter spp. is a leading bacterial cause of human diarrheal illness worldwide and also one of the most common enteric bacterial pathogens in dogs. The exact role of Campylobacter spp. as an obligate enteric pathogen is sometimes considered difficult to asses because it can also be isolated from healthy animals. However, it is significantly more often isolated from diarrheic dogs and also excreted in much higher quantities. Research of Campylobacter spp. in healthy and diarrheic dogs suggests that different species may have a different clinical significance in dogs. Aim of this study was to compare isolation rates of Campylobacter spp. in healthy and diarrheic dogs and identify species of isolated bacteria. Fecal samples of 190 (105 diarrheic and 85 healthy) dogs were tested for Campylobacter spp. Samples were submitted to the laboratory within six hours from collection, plated on mCCDA medium and incubated under microaerophilic conditions for 98 hours. Species was determined for twenty isolates, using MALDI TOF mass spectrometry. Dogs were divided into two groups: younger and older than 12 months. Statistical analysis was done by chi square test. Campylobacter spp. was isolated from 44 (23, 2%) dogs. It was significantly more frequently detected in diarrheic (36, 2%) than in healthy (7, 0%) animals (p<0.01). In healthy dogs, Campylobacter spp. was more frequently isolated from dogs younger that 12 months (p<0.01). In diarrheic dogs, there was no difference in isolation rates between age groups. All isolates were identified as C. jejuni. Results of this investigation clearly demonstrate that Campylobacter spp. has a significant role in pathogenesis of gastroenteritis in dogs. Higher isolation rate in diarrheic dogs is probably a result of dominance of C. jejuni. In studies that reported similar isolation rates in healthy and diarrheic dogs, C. upsaliensis was the most prevalent species, which points out the importance of Campylobacter species identification. In population of healthy dogs, young animals are more likely to shed Campylobacter spp. while in diarrheic dogs there is equal possibility of campylobacteriosis in all age groups.
