I had given a sputum for culture and it showed K pneumonia heavy growth. In 2021 also i had same infection and was treated with cefuroxime.. idk how it came back! My parents also cough most of the time and when i asked them to get tested for this as a precautionary measure, they tend to scold me.. This time cefuroxime shows resistance.. So i am worried if my parents have it, i might get it again and another antibiotics will get resistant! Do they really need to test it and get treatment if indicated? Or I am thinking way too much? But they do dry cough many times. Please guide me.
