Extended-Spectrum β-Lactamases inEscherichia coli and Klebsiellapneumoniaein Gulls, Alaska, USA

Previously reported babesiosis cases in children have been mostly acquired by blood transfusion (10). The patient had no history of transfusions with blood products and had never traveled outside his home town before disease onset. Although he and his parents did not recall any tick bites, he was at high risk for exposure to ticks because he often played with his dog, which frequently went outdoors in a tick-infested forested area. The dog may have transmitted a Babesia sp.-infected tick to the patient. However, ticks from the dog were not available for identification and testing.
