Concomitant Campylobacteriosis in a Puppy and in Its Caregiver: A One Health Perspective Paradigm in Human-Pet Relationship

SIMPLE SUMMARY: Dogs are considered family members and a growing amount of attention has been dedicated to their nutrition by pet parents during last decades. The administration of unbalanced, poultry-based raw diets (PRD) has represented a rising trend, with some nutritional and microbiological implications on both pets and human wellbeing. Here, we report a case of a laboratory-confirmed Campylobacter (C). jejuni and C. upsaliensis symptomatic infection in a puppy, a French Bouledogue, female, 6 months of age, and fed a PRD, and in its owner. Both recovered after appropriate diagnostic investigations and treatments: however, hospitalization and a long course of antimicrobials were necessary to fight the multi-drug-resistant infection. This case underlines the potential risk of Campylobacter spp. exposure related to current pet food fads, highlighting the importance of the One Health approach, where veterinarians, physicians and caregivers need to develop effective strategies for the prevention of zoonoses spread. ABSTRACT: We report a case of laboratory-confirmed Campylobacter (C). jejuni and C. upsaliensis symptomatic infection in a puppy, a French Bouledogue, female, 6 months of age, fed a raw, unbalanced, poultry-based diet (RPD), (48.1 CP, 33% EE, 0.3% Ca, 0.5% Phos, 0.5 Ca/P, on a dry-matter basis), and in its owner. Soon after adoption, the pet and the caregiver showed severe gastrointestinal signs and needed hospitalization. Fecal PCR assays, selective cultures, and antibiotic susceptibility testing were performed, and multi-drug resistant C. jejuni and C. upsaliensis were isolated from the feces of both. The same bacteria were also identified by FISH in the dog colonic biopsies collected during endoscopy. The puppy was prescribed a complete commercial diet for growing dogs, (30.00% CP, 21.00% EE, 1.2% Ca; 1% Phos; as fed) and treated with ciprofloxacin. The dog and the man healed uneventfully and tested negative for further fecal PCR analyses. This report focuses on dog nutritional management and explores the potential routes of exposure, with emphasis on emerging outbreaks related to current pet food fads. Our data support the One Health approach, where veterinarians, physicians, and owners are challenged to build effective stewardship to prevent the spread of zoonoses.
