Resumen en ingles
Using phenotype techniques, characterization was made to species and serovar of 3,112 strains of
Listeria, isolated from different sources of infection such as human (247-7.9%) and animals (239-7.6%),
as well as from various routes of infection, including food (2,330-74.8%) and environmental constituents (296-9.5%), all coming from different regions of the country and collected during the period 1971-
1997. The following species were recovered in the cultures analysed: L. monocytogenes (774-24.8%),
L. innocua (2,269-72.9%), L. seeligeri (37-1.1%), L. welshimeri (22-0.7%), L. grayi (9-0.2%), and L.
ivanovii (1-0.03%). L. monocytogenes was represented by ten serovars, the most prevalent being 4b
(352-11.3%), 1/2a (162-5.2%), and 1/2b (148-4.7%). The predominant serovar in L. innocua was 6a
(2,093-67.2%). Considerations about laboratory methods for diagnosis and epidemiological aspects
are presented on the basis of the results obtained.
