<s>[INST] hye, My aunt is having shortness of breath and she is on vent now. Her breast showed some kind of infection that apparently turned out to have black blisters. I could she those spreading. When we went for lungs x-ray doctor said she has accumulation of water in her lungs [/INST] Thanks for your question on Health Care Magic. I can understand your aunt's situation and problem. By your history and description, possibility of bacterial infection especially staphylococcus is more in her case. She is having pleural effusion and infective skin lesions on breast. Staphylococcus can cause pleural effusion and blister formation on skin. So chances of staphylococcal infection is more in her case. Better to send pleural fluid culture and sensitivity for the diagnosis of staphylococcal infection. This will also tell about effective antibiotic therapy. With appropriate antibiotics and Care, this infection can be treated. Hope I have solved your query. Wishing good health to your aunt. Thanks. </s>
