Multidrug-Resistant Campylobacter Outbreak Linked to Pet Store Puppies Reaches 12 States
By Amy Orciari Herman
A Campylobacter outbreak linked to pet store puppies has affected 55 people in 12 states, the CDC said in an advisory. Tests indicate that the isolates are resistant to most first-line antibiotics.
The outbreak is linked to puppies sold through the national pet store chain, Petland. Whole-genome sequencing of all specimens from seven ill patients and six ill puppies indicated resistance to azithromycin, ciprofloxacin, clindamycin, erythromycin, nalidixic acid, and telithromycin. Most specimens were also resistant to gentamicin and tetracycline.
The CDC notes that most infected people recover without treatment. Antimicrobial therapy is necessary only for people with, or at high risk for, severe illness.
Of the 55 cases, 14 are store employees; 35 recently visited Petland, purchased a puppy from Petland, or visited a home with a Petland puppy; 1 had sexual contact with an infected person; 4 had exposure to puppies from numerous sources; and 1 had an unknown exposure.
