In an update to the multistate outbreak of multidrug-resistant Campylobacter infections linked to Petland pet store puppies, the Centers for Disease Control and Prevention (CDC) reports an additional 12 cases, bringing the total to 67.

The cases were reported from 15 states, with Ohio seeing the most cases at 24. About a quarter of the total cases required hospitalization and no deaths have been reported.

Of the 67 ill people in this outbreak, 62 (93%) have an epidemiological link to puppies at or from a Petland store–Eighteen patients were Petland employees; Forty- four people either recently purchased a puppy from Petland, visited a Petland store, or live in or visited a home with a puppy sold by Petland before their illness began and of the other five ill people, four reported contact with puppies from other sources and one had a laboratory-confirmed infection and did not report any puppy exposure.

Campylobacter bacteria isolated from clinical samples from people sickened in this outbreak were found to be resistant to commonly recommended, first-line antibiotics.
