Commensals: Underappreciated Reservoir of Antibiotic Resistance
A ntibiotic resistance, reported for sulfonamides in the mid-1930s and for penicillins in the 1940s, remains a stubborn quandary. What was once confined mainly to hospitals increasingly involves multidrug resistance that encompasses communities and encircles the globe. Virtually all types of bacterial infections are becoming resistant to antibiotic treatments, according to officials at the Cent...
متن کاملSponge Microbiota Are a Reservoir of Functional Antibiotic Resistance Genes
Wide application of antibiotics has contributed to the evolution of multi-drug resistant human pathogens, resulting in poorer treatment outcomes for infections. In the marine environment, seawater samples have been investigated as a resistance reservoir; however, no studies have methodically examined sponges as a reservoir of antibiotic resistance. Sponges could be important in this respect bec...
متن کاملThe ocean as a global reservoir of antibiotic resistance genes.
Recent studies of natural environments have revealed vast genetic reservoirs of antibiotic resistance (AR) genes. Soil bacteria and human pathogens share AR genes, and AR genes have been discovered in a variety of habitats. However, there is little knowledge about the presence and diversity of AR genes in marine environments and which organisms host AR genes. To address this, we identified the ...
متن کاملThe Gut as Reservoir of Antibiotic Resistance: Microbial Diversity of Tetracycline Resistance in Mother and Infant
The microbiota in the human gastrointestinal tract (GIT) is highly exposed to antibiotics, and may be an important reservoir of resistant strains and transferable resistance genes. Maternal GIT strains can be transmitted to the offspring, and resistances could be acquired from birth. This is a case study using a metagenomic approach to determine the diversity of microorganisms conferring tetrac...
متن کاملUncultured soil bacteria are a reservoir of new antibiotic resistance genes.
Antibiotic resistance genes are typically isolated by cloning from cultured bacteria or by polymerase chain reaction (PCR) amplification from environmental samples. These methods do not access the potential reservoir of undiscovered antibiotic resistance genes harboured by soil bacteria because most soil bacteria are not cultured readily, and PCR detection of antibiotic resistance genes depends...
