Understanding drug resistance in human intestinal protozoa

Parasitology Research
Hend Aly El-Taweel

Abstract

Infections with intestinal protozoa continue to be a major health problem in many areas of the world. The widespread use of a limited number of therapeutic agents for their management and control raises concerns about development of drug resistance. Generally, the use of any antimicrobial agent should be accompanied by meticulous monitoring of its efficacy and measures to minimize resistance formation. Evidence for the occurrence of drug resistance in different intestinal protozoa comes from case studies and clinical trials, sometimes with a limited number of patients. Large-scale field-based assessment of drug resistance and drug sensitivity testing of clinical isolates are needed. Furthermore, the association of drug resistance with certain geographic isolates or genotypes deserves consideration. Drug resistance has been triggered in vitro and has been linked to modification of pyruvate:ferredoxin oxidoreductase, nitroreductases, antioxidant defense, or cytoskeletal system. Further mechanistic studies will have important implications in the development of second generation therapeutic agents.
