<s>[INST] I have had a sinus infection since October and have been on numerous doses of antibiotics.  When I had an explosion of fluid run out of my sinuses last week, I went back to the ENT and he saw there was still an infection.  This time he did a culture and I have Corynebacterium Species. [/INST] hi i cannot directly suggest treatment for corynebacterium species as a culture of the same bacteria has to be done by your doctor and then treatment  to be started acorrding to culture and sensitivity. </s>
