Characterization of Enterococcus faecalis isolates by chicken embryo lethality assay and ERIC-PCR

What is it about?

This study is the second part of my Ph.D., which is entitled “Virulence characterization of avian Enterococcus faecalis field isolates and genetic approach to select more resistant laying hens”. Little is known about the risk from field avian E. faecalis strains and it is currently difficult to estimate its virulence degree. Therefore, a thorough understanding of the risk from field E. faecalis strains is needed in order to develop effective control strategies against bacterial infections to reduce the incidence rate of AA and, consequently, to guarantee the welfare of the birds and improve their economic performance.

Why is it important?

Virulence characterization of avian E. faecalis field isolates allows us to know the risk that the strains represent and provide valuable information, which can be important for the selection of isolated for the production of vaccines. The ERIC-PCR can be applied successfully to obtain the genetic distribution and epidemiology of E. faecalis strains.
