      We constructed two collections of targeted single gene deletion (SGD) mutants and two collections of targeted multi-gene deletion (MGD) mutants in Salmonella enterica sv Typhimurium 14028s. The SGD mutant collections ...
    • Infection of Mice by Salmonella enterica Serovar Enteritidis Involves Additional Genes That Are Absent in ... 
      Silva, Cecilia A.; Blondel, Carlos J.; Quezada, Carolina P.; Porwollik, Steffen; Andrews Polymenis, Helene L.; Toro, Cecilia S.; Zaldívar San Román, María Mercedes; Contreras, Inés; McClelland, Michael; Santiviago Cid, Carlos (AMER SOC MICROBIOLOGY, 2012-02)
      Salmonella enterica serovar Enteritidis causes a systemic, typhoid-like infection in newly hatched poultry and mice. In the present study, a library of 54,000 transposon mutants of S. Enteritidis phage type 4 (PT4) strain ...
    • Spontaneous Excision of the Salmonella enterica Serovar Enteritidis-Specific Defective Prophage-Like Element SE14 
      Santiviago Cid, Carlos; Blondel, Carlos; Quezada, Carolina P.; Silva, Cecilia A.; Tobar, Pia M.; Porwollik, Steffen; McClelland, Michael; Andrews Polymenis, Helene L.; Toro, Cecilia S.; Zaldívar San Román, María Mercedes; Contreras, Inés (2010-04)
      Salmonella enterica serovar Enteritidis has emerged as a major health problem worldwide in the last few decades. DNA loci unique to S. Enteritidis can provide markers for detection of this pathogen and may reveal pathogenic ...
