Isolation and Identification of Listeria monocytogenes from Various Clinical Cases

Abstract

The study involved the isolation and identification of bacterium Listeria monocytogenes (L .monocytogenes) from (132) placental and cervical swabs collected from women with abortions and preterm labour. The isolation of this bacterium were 20 out of 150 bacterial isolates (13.3 %). The 20 isolates distributed into 17 isolates from Cervix (12.87%) out of 132 and 3 isolates out of 18 placental isolates(16.7 %).The results showed that (9) out of 20 (45 %) isolates were from abortion and 11 isolates out of 20 (55%) were from preterm labour. 2 isolated out of 26 isolates (7.69 %) of the bacterium were also abtained from Cerbero-Spinal Fluid (CSF) of neonates suspectedly infected with purulent meningitis. A Key for the identification of the genus Listeria and the species L .monocytogenes is suggested in this study.
