Brief Answer: DETAILS ARE GIVEN BELOW. Detailed Answer: Hello, Thanks for writing to us. Citrobacter koseri is gram negative bacillus and acts as opportunistic pathogen in a variety of human infections. It may be transmitted via raw food stuffs and vegetables, improper hand washing or feco-oral route. It has been suggested that C. koseri has a unique ability to penetrate, survive, and replicate into vascular endothelial cells and macrophages. Therefore, it can cause sepsis, brain abscess or infection, seizures, ventriculitis, cerebritis etc if it is left untreated. CT scan or MRI investigation will be worthwhile in this case. TREATMENT: Broad spectrum antibiotic like Cephalosporin and Meropenem are often used because of the good penetration into the CNS. If the response to the antibiotic is poor, the surgical aspiration of the collected pus reduces the mass effect and enhances the efficacy of the antibiotics (in severe case). Kindly, consult with your doctor for complete prescription and proper guidance. Hope, I have answered your query. Kindly, close the discussion if you don't have any other query. Wish your good health and take care yourself. Regards, Dr Soumen For future query, you can directly approach me through WWW.WWWW.WW
