Antibiotic Resistance Genetic Markers and Integrons in White Soft Cheese: Aspects of Clinical Resistome and Potentiality of Horizontal Gene Transfer
Antibiotic resistance poses an important threat to global public health and has become a challenge to modern medicine. The occurrence of antibiotic-resistant bacteria in a broad range of foods has led to a growing concern about the impact that food may have as a reservoir of antibiotic resistance genes. Considering Minas Frescal Cheese (MFC)-a typical Brazilian white soft cheese-and its economi...
متن کاملBypass of genetic constraints during mutator evolution to antibiotic resistance.
Genetic constraints can block many mutational pathways to optimal genotypes in real fitness landscapes, yet the extent to which this can limit evolution remains to be determined. Interestingly, mutator bacteria elevate only specific types of mutations, and therefore could be very sensitive to genetic constraints. Testing this possibility is not only clinically relevant, but can also inform abou...
متن کاملGenetic Regulation of Virulence and Antibiotic Resistance in Acinetobacter baumannii
Multidrug resistant microorganisms are forecast to become the single biggest challenge to medical care in the 21st century. Over the last decades, members of the genus Acinetobacter have emerged as bacterial opportunistic pathogens, in particular as challenging nosocomial pathogens because of the rapid evolution of antimicrobial resistances. Although we lack fundamental biological insight into ...
متن کاملGenetic alteration in drug resistance markers of Plasmodium falciparum.
Plasmodium falciparum shows plasticity in its genome. For its survival it can delete certain genes (or portions) if not needed for its growth and has the capability to regulate its genes under various stages of its life cycle as well as under unfavourable environmental conditions. Parasite shows enormous amount of antigenic variation under immune pressure leading to the emergence of vaccine res...
متن کاملUnconventional circularizable bacterial genetic structures carrying antibiotic resistance determinants.
Particular genetic structures which—though they lack their own recombinase genes— can be excised in circular form thanks to extensive direct repeats (DRs) flanking the DNA segment undergoing excision have recently been described in both Gram-negative and Gram-positive bacteria (1–6). They carry mostly antibiotic resistance genes. The earliest and the latest three of the above-noted studies were...
