QUEBEC - Three Canadian soldiers infected with a bacteria are under quarantine at a Quebec City hospital.

A hospital spokeswoman says the soldiers returned from Afghanistan last Friday.

Genevieve Dupuis says they stayed at the military hospital in Kandahar before arriving in Quebec City.

She says two civilian patients staying near the soldiers at the Quebec City hospital have also been isolated due to concern they may have caught the bacteria.

Dupuis says Acinetobacter Baumannii usually invades wounds and is commonly found in hospitals that treat wounded soldiers.

She says around 15 soldiers have returned to Quebec City with the bacteria since 2007.
