Isolation and Identification of Bacterial Meningitis From Children

Abstract

Fifty samples of C.S.F. were collected from Patients with suspected to have meningitis with ages, ranged from less than 1 month to seven years.The results showed that the rate of bacterial infection was 26%, the causative bacteria includes both Gram positive and negative bacteria. Gram positive constitute 53.8% of which Streptococcus pneumoniae formed the highest rate (25%) followed by Staph. aureus, Staph. simulanus with percentage 15.4%, 7.7% respectively and lastly Listeria monocytogenes 7.7%. While gram negative bacteria was isolated at a rate of 46.2% Nesseria meningitidis constitute the highest isolation rate (30.8%) then Haemophilus influenzae,Pseudo.aerginosa at ratio of 7.7% for them.The study also showed that the rate of infection was higher in females (53.84%) while it was 46.15% in males. It appeared that N. meningitidis and Strep. pneumoniae was isolated at a rate of 50% from children less than one month and Strep. pneumoniae was also isolated at a rate of 28.57% from children aged between 1 month to four years while Staph.aureus was isolated at rate of 66.7% from children more than four years,Staph. Simulanus, Listeria monocytogenes, Nesseria meningitidis and Pseudomonas aeroginosa was isolated from children between 1 month to four years only at arate of 14.28, 14.28, 28.57, 14.28 respectively. the results also showed that 30.8% of the patients with Bacterial Meningitis had hydrocephalus and those patient have also an increase in the number of white blood cells (96) cells/ml3 compared with 33 cells/ml3 and in protein concentration 1.6 mmol/L and 0.8 mmol/L while there is no difference in glucose concentration which showed low concentration in both groups.
