Abstract

Introduction & Background: Listeriosis is an emerging zoonotic disease. Listeria monocytogenes is an uncommon cause of illness in general population, however, in some high risk groups including neonates, pregnant women, elderly persons, immunosuppressed transplant recipients and others with impaired cell mediated immunity, it is important cause of life threatening bacteremia meningoencephalitis. Listeriosis is 18 times more common in pregnancy (12/100,000) than in the non-pregnant population (0.7/100,000) and 16-27% of all infections with Listeria occur in pregnant women.
Materials and Methods: Isolation of bacteria by conventional methods of microscopy and culture on selective agar PALCUM agar after enrichment of samples by using UVM1, UVM2 .Speciation of listeria done by carbohydrate fermentation test followed by study of pathogenicity by hemolysis on sheep blood agar and CAMP test followed by antimicrobial susceptibility test done.
Result: Out of total 131 patients having history of Spontaneous abortion were screened for Listeria, in that 10(7.6%) were carrying Listeria out of which 3(2.29%) of them found to be positive for L. monocytogenes and 07(5.34%) were other Listeria spp. The prevalence of L. monocytogenes in present study was 03(2.29%) from spontaneous abortion cases.
Conclusion: Based on the results of present study it is concluded that Listeria monocytogenes is responsible for spontaneous abortions in spontaneous abortion during pregnancy in humans.
