WebDec 1, 2004 · Listeria monocytogenes is a foodborne pathogen frequently present in ripened soft cheeses. Forty-three strains of L. monocytogenes isolated from the rind of ripened Gorgonzola cheeses produced in 24 different dairy plants were characterized by biotyping, serotyping, and molecular typing. Biotyping was performed by studying two … WebA wide variety of molecular and physiological tools have been employed for characterization at the strain or isolate level (1,2). Intraspecies differentiation of bacteria can be based on taxonomic features, such as morphology, biochemical properties (biotyping), virulence (pathotyping), and antigenic structure (serotyping).
