P. aeruginosa is a bacterium that can cause severe infection in immunocompromised individuals or patients in the hospital. Infections of the blood, pneumonia, and other infections following a surgery are caused by this bacterium. Mild ear infections and skin rashes can occur when the bacterium affects healthy people.
This infection can develop diarrhea, fever, and abdominal cramps. Most people recover without treatment, however, in some instances, the diarrhea can be so severe that the patients are hospitalized.
Burkholderia pseudomallei causes the disease Melioidosis; some symptoms are: localized pain, fever, abscess, cough, and weight loss. It is more common in tropical climates, especially Southeast Asia and Australis.
