The gut microbiota residing in the intestinal tract composes of an abundant and diverse population of microbes including bacteria, viruses, and microbial eukaryotes, which plays a significant role in maintaining host health. It bidirectionally affecting physiological processes through the "cross-talk" with the host cells, these various processes include immune modulation, neurotransmitter regulation, hormones secretion and regulation, and the production of many antioxidants and metabolites. The composition of the gut microbiota varies from individual to individual, but the microbial community in each individual is relatively stable over time. The overuse of antibiotics poses unignorable issues toward the homeostasis of the gut ecosystem. Because they not only act on microbes that cause infections but also affect the "good microbes" and even cause dysbiosis. Antibiotic resistance testing can be a valuable tool in studying the antibiotic-microbiota-health topics.
Antibiotic resistance of microbes is encoded in their resistance genes, either intrinsic or acquired, which indicates that the antibiotic susceptibility can be interpreted through high-throughput sequencing data. While the phenotype is determined by many factors, the antibiotic resistance testing, antibiotic sensitivity testing, or antibiotic susceptibility testing (AST) can be a rapid, direct, and effective approach to evaluate the sensitivity that a specific microorganism can be affected by antibiotics. Antibiotic resistance testing has significance in studying microbiota and host homeostasis.
