Ten projects were funded by the National Institute of Allergy and Infectious Diseases of the National Institutes of Health (NIAID). Diagnostic tools Congenital and adult syphilis are currently diagnosed by a series of tests that have limited accuracy. According to the Centers for Disease Control and Prevention, adult and congenital syphilis increased by 80 % and 183 % respectively between 2018 and 2020. This crisis prompted the U.S. Department of Health and Human Services. Create a national working group Responding to epidemics.

“Antibiotics for syphilis are effective, but outdated tests make it difficult to ensure patients receive the correct diagnosis and treatment,” said NIAID Director Jeanne M. Marrazzo, MD. “Advanced diagnostics would simplify syphilis treatment and improve our ability to evaluate syphilis vaccine candidates and other prevention methods.”

Syphilis, a sexually transmitted infection caused by the bacteria Treponema pallidum. The disease can cause neurological and organ damage in adults as well as birth defects, neonatal death, and congenital anomalies. According to the CDC, syphilis cases in the United States have increased significantly since 2000. This is mainly due to a dramatic increase in cases that began in 2019.

Current syphilis tests require at least two antibody-based tests that are decades old. They are unable to distinguish between antibodies from an active or resolved infection. These tests cannot consistently confirm whether antibiotics have cleared the infection. T. pallidum Bacteria are eliminated from the human body. Modern molecular diagnostic techniques such as nucleic acid amplification platforms and systems that detect fragments of a pathogen are used for the diagnosis of other infectious diseases. They could also be applied to syphilis.

These grants will explore a broad range of concepts in immunology and diagnostics, such as basic research into childhood immunity to syphilis or new diagnostic tests to identify the different parts T. pallidum Measurements of antimicrobial resistance and genomic material in infants, adults and children T. pallidum Strains and testing platforms that can be used at the point of care rather than in an external laboratory. The grants, totaling $2.4 million, are distributed among the recipients as follows:
