Understanding how antibiotics work against Shigella infections

Official title: Pharmacokinetic and pharmacodynamic relationships for antibacterial treatment of shigellosis

Funded at University of Washington · NIH-11061255 · Data updated 2026-11-12

This study is looking at how well different antibacterial treatments work for Shigella infections, which can cause bad diarrhea, especially in kids, to find better options that can help fight off resistant strains of the bacteria.

Who could benefit from this research

Could help

Ideal candidates for this research include children under 11 years old who are experiencing Shigella infections, particularly in low-resource settings.

Less likely to help

Patients with Shigella infections who are not in the targeted age group or those who do not reside in areas affected by drug-resistant strains may not benefit from this research.

What this research studies

This research investigates the effectiveness of different antibacterial treatments for Shigella infections, which can cause severe diarrhea and dysentery, particularly in children. The study aims to identify how the characteristics of these treatments influence their success and the development of drug resistance. By establishing a framework for evaluating these relationships, the research seeks to optimize existing therapies and develop new ones. Patients may benefit from improved treatment options that are more effective against resistant strains of Shigella.

Why it matters

Potential benefit: If successful, this research could lead to more effective treatments for Shigella infections, reducing morbidity and mortality, especially in vulnerable populations.

How similar studies have gone: Previous research has shown success in understanding drug exposure relationships for other gastrointestinal pathogens, indicating potential for similar advancements in treating Shigella.
