Infectious Laryngotracheitis Virus (ILTV)

ID Screen® ILT gB Indirect


Indirect ELISA for the detection of antibodies against the gB protein of the avian ILT virus in chicken serum or plasma

For the monitoring of vaccination with recombinant FP-ILTgB vaccines.





  • The only commercial quantitative ELISA for the monitoring of Vectormune® FP-LT vaccine (not suitable for use with HVT-gB vaccines)
  • unique solution to substitute the visual control of vaccine uptake, which is time-consuming
  • Detects field infection in vaccinated flocks (an increase in antibody titers is observed post-infection). You may confirm the challenge using the ID Screen® ILT gI Indirect ELISA.
  • May be used as part of a DIVA* strategy for flocks vaccinated with recombinant vaccines using a glycoprotein different from the gB (e.g. Innovax-ILT, Vaxxitek HVT+IBD+ILT)
  • Validated for use with Serum Transport Cards, allowing for practical and safe shipment of blood or serum samples to the lab
