New NOSI Stimulates Research Targeting Pathogens Within the Arthropod Vector

Vector-borne diseases account for 17 percent of all infectious diseases world-wide. Arthropod vectors can transmit viruses, bacteria, parasites, and nematodes to humans resulting in high morbidity and mortality in endemic countries. While human- and vector-focused interventions have had some success, these measures have not achieved sufficient levels of control to prevent or eliminate vector-borne disease burden. There is a need to develop novel approaches that are effective, safe for the environment, and do not promote the development of resistance.

NIAID’s Notice of Special Interest (NOSI)—Targeting the Pathogen Within the Arthropod Vector aims to stimulate multidisciplinary research that targets the pathogen within the invertebrate host to prevent its transmission to the vertebrate host.

Research Objectives

Successful novel approaches will:

  • Target the pathogen within the arthropod vector.
  • Use transgenics targeting ligand/receptor molecules in the pathogen/vector or that hinder development of the pathogen in the vector.
  • Use vector symbionts to hamper pathogen development or transmission to the vertebrate host.
  • Use ‘omics data and computational methodologies to identify likely targets.

Examples of NIAID-specific areas of research include:

  • Multidisciplinary collaborative research on pathogen (virus, bacteria, parasite, nematode) biology within the arthropod vector (mosquito, tick, sand fly, black fly, tsetse fly, triatomine bug, fleas, and body lice), as well as vector-pathogen or microbiome interactions that will accelerate the identification of targets to prevent the pathogen from developing and being transmitted to a vertebrate host.
  • Use of computational, systems biology, or modeling approaches to develop hypotheses that can be tested.

Application and Submission Information

This notice applies to due dates on or after February 5, 2023, and subsequent standard receipt dates through January 7, 2026.
