Resumen

Listeria monocytogenes is one of the most important bacteria associated with foodborne diseases, soft cheese being an important L. monocytogenes vehicle. In Ecuador, soft cheese is consumed in 84.3% of urban households. We determined the prevalence of L. monocytogenes and serogroups in 260 fresh artisanal soft cheese samples collected in 18 of 24 Ecuadorian provinces. Listeria spp. detection was carried out by culture-dependent and independent methods; 14.23% of samples were positive for L. monocytogenes. Serogroup IVb was found in 83.78% of the food isolates. Serogroups IIb and IIa were present in 8.11% of our isolates. To our knowledge, this is the first report of L. monocytogenes serogroups associated with food in Ecuador; we also found serogroup similarities between cheese isolates and clinical isolates.
