Microbial study of meningitis and encephalitis cases.
Meningitis and/or encephalitis can pose a serious public health problem especially during outbreaks. A rapid and accurate diagnosis is important for effective earlier treatment. This study aimed to identify the possible microbial causes of meningitis and/or encephalitis cases. CSF and serum samples were collected from 322 patients who had signs and symptoms suggestive of meningitis and/or encephalitis. Out of 250 cases with confirmed clinical diagnosis, 83 (33.2%) were definitely diagnosed as bacterial meningitis and/or encephalitis cases (by using CSF culture, biochemical tests, latex agglutination test, and CSF stain), 17 (6.8%) were definitely diagnosed as having viral causes ( by viral isolation on tissue culture, PCR and ELISA), and one (0.4%) was diagnosed as fungal meningitis case (by India ink stain, culture, and biochemical tests). Also, there was one encephalitis case with positive serum ELISA IgM antibodies against Sandfly scilian virus. N. meningitidis, S. pneumonia and M. tuberculosis were the most frequently detected bacterial agents, while Enteroviruses, herpes simplex viruses and varicella zoster viruses were the most common viral agents encountered. Further studies are needed to assess the role of different microbial agents in CNS infections and their effective methods of diagnosis.
