MILWAUKEE (AP) -- A bacterial strain that killed more than 1,000 dogs in outbreaks in Las Vegas and Miami has been found in some of the seven dogs that were stricken and died at a Wisconsin shelter.

The Wisconsin Veterinary Diagnostic Laboratory in Madison says some dogs from the Humane Animal Welfare Society of Waukesha County had the strain of bacteria that rapidly attacks the respiratory system but is treatable with antibiotics.

The lab says workers also identified a parainfluenza virus in at least one of the three dogs brought in so far. More tests are being done, and the lab should know more within a few days.

Lynn Olenik heads the Waukesha County shelter.

She says seven dogs died over 10 days. Two others with early symptoms responded to antibiotics and she expects them to survive. No other dogs or other animals at the shelter seem to be affected.

The facility has stopped taking new dogs or adopting dogs out. Olenik says it could be another two or three weeks before those activities resume.
