TL;DR: The results showed that, despite the ability of metal tolerant strains to survive and grow in the presence of these elements, the interactions with these metals may result in metabolic or phisiological changes in this group of bacteria.
Journal ArticleDOI
Prevalência de sorovares de Salmonella isolados de aves no Brasil
TL;DR: Serovar diversity was found to serogroup O:7 that accounted for 22 different types, followed by serogroups O:4, O:3,10 and O:9 with 19, 15 and 10 serotypes respectively, which were the most frequent serovars over the 30 years.
Journal ArticleDOI
Incidence of Listeria monocytogenes in cheese produced in Rio de Janeiro, Brazil
TL;DR: Three serotypes (1/2a, 1/2b and 4b) were observed among the strains of L. monocytogenes isolated, all of them being frequently involved in outbreaks of foodborne listeriosis and sporadic cases of the disease all over the world.
Journal ArticleDOI

Journal ArticleDOI
Species and serovars of the genus Listeria isolated from different sources in Brazil from 1971 to 1997.
TL;DR: 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 and animals and animals as well as from various routes of infection, including food and environmental constituents, during the period 1971-1997.
