--- This study was conducted in order to characterize strains of Listeria monocytogenes isolates from the San Bartolome´s Hospital in Lima-Peru during the years from 2001 to 2005. During the study period, we identified 18 cases of perinatal listeriosis, which were isolated 20 strains of L. monocytogenes. The strains were characterized by conventional tests and molecular biology techniques. The 20 strains studied were identified by known phenotypic characteristics of L. monocytogenes, such as the presence of incomplete β-hemolysis, positive CAMP reaction with S. aureus and negative CAMP reaction with R. equi, and the use of carbohydrates as D-glucose and L-rhamnose but not from D-xylose or D-mannitol. The strains of L. monocytogenes were confirmed by polymerase chain reaction and typed by random amplified polymorphic DNA (RAPD) technique. With the primers OMP-01 and PJ108 were obtained six RAPD types, distributed as follows: eight strains of type AI, three of each type A-II, A-III and B-II, two type B-I and one strain of type A-IV. We conclude that, in 18 cases of listeriosis were obtained 20 strains of L. monocytogenes with six different genotypes, RAPD type A-I being the most frequent (8/20, 40%) among the studied strains.
