 Symptoms of "A. baumannii" infections in turn range from fevers and chills, rash, confusion and/or altered mental states, pain or burning sensations when urinating, strong urge to urinate frequently, sensitivity to bright light, nausea (with or without vomiting), muscle and chest pains, breathing problems, and cough (with or without yellow, green, or bloody mucus).In some cases, "A. baumannii" may present no infection or symptoms, as with colonizing an open wound or tracheostomy site.Because most infections are now resistant to multiple drugs, determining what susceptibilities the particular strain has is necessary for treatment to be successful.
