Antimicrobial Resistance and Ecology: A Dialog Yet to Begin
Authors: Bader MS, Loeb M, Leto D, Brooks AA Abstract Urinary tract infections (UTIs) caused by antibiotic- resistant Gram-negative bacteria are a growing concern due to limited treatment options. Knowledge of the common uropathogens in addition to local susceptibility patterns is essential in determining appropriate empiric antibiotic therapy of UTIs. The recommended first-line empiric antibiotic therapy for acute uncomplicated bacterial cystitis in otherwise healthy adult nonpregnant females is a 5-day course of nitrofurantion, a 3-g single dose of fosfomycin tromethamine, or a 5-day course of pevmecillinam. High...
C-CAMP, an initiative of the Dept of Biotechnology, Ministry of Science and Technology, and the prominent public private partnership organization in the Netherland, have decided to build and nurture innovations that address the global AMR threat.
ConclusionsThe diverse variety of antibiotic resistance genes and the high antibiotic resistance rates to last-resort antibiotics such as carbapenems and colistin, is indicative of a highly adaptable strain. This emphasizes the importance of implementation of infection controls measures, continued monitoring of antibiotic resistance and prudent use of antibiotics to prevent further selection of resistant strains and the emergence of pan-resistant clones.
ConclusionThe study highlights the importance of regular surveillance programs, an efficient infection control program, strict adherence to antiseptic measures and use of a rational antibiotic policy for the early diagnosis and better management of CRBSI.
ConclusionThe draft genome sequence reported here will lay the foundation for future research on antimicrobial resistance and pathogenic mechanisms in K. quasipneumoniae subsp. quasipneumoniae and also will promote comparative analysis with genomic features among different sources of clinically important multidrug-resistant strains.
ConclusionIt is concluded that NIT resistance in the studied NIT-RE. coli isolates was mainly mediated by nfsA and nfsB alterations.
ConclusionOur findings suggest that curcumin has potential as an anticlostridial agent. More work is needed to further investigate the efficacy of curcumin as a standalone drug or as a supplement of current drugs of choice, as it has no antagonistic activities but might overcome their drawbacks.
Authors: Bassetti M, Giacobbe DR, Peghin M, Irani P Abstract Introduction: Antimicrobial resistance poses a substantial threat to global public health concern, since it decreases the probability of effectively treating an infection and increases risk of morbidity and mortality. Areas covered: In this review, the authors discuss the advantages and disadvantages of classical and novel trial designs for evaluating novel antibiotics for infections due to multidrug-resistant organisms (MDRO). An inductive literature search was performed using different keywords pertinent to the reviewed topics. Expert opinion: The need ...
This study investigated the C. acnes inhibitory activity of Callicarpa americana leaves, a native Southeastern United States shrub historically used by Native Americans to treat fever, stomachache, and pruritis. Flash chromatography fractions of the ethyl acetate-soluble C. americana ethanol leaf extract (649C-F9 and 649C-F13) exhibited MICs ranging from 16 to 32 µg ml−1 and IC50 range of 4–32 μg ml−1 against a panel of 10 distinct C. acnes isolates. Cytotoxicity against an immortalized human keratinocyte cell line (HaCaTs) skin was detected at more than eight times the dose required for growth i...
ConclusionsCarbapenamase production along with intrinsic colistin resistance in infecting bacterial pathogens can cause fatal outcomes in the resource limited countries like Nepal where new antibiotic combinations ceftazidime+ Avibactam, or aztreonam +avibactam are not available. Drug resistance patterns including OXA 48 producer should be characterized in all cases by standard phenotypic methods or by Xpert Carba-R assay and larger studies are required to know the exact burden of OXA 48 producer in Nepal.
