(CNN) — Every 15 minutes, someone in the United States dies of a superbug that has learned to outsmart even our most sophisticated antibiotics, according to a new report from the US Centers for Disease Control and Prevention.
That’s about 35,000 deaths each year from drug-resistant infections, according to the landmark report.
The report places five drug-resistant superbugs on the CDC’s “urgent threat” list — two more germs than were on the CDC’s list in 2013, the last time the agency issued a report on antibiotic resistance.

ConclusionCirculating MDR A. baumannii exhibit genetic heterogeneity with variations in the structure and content of genomic A. baumannii resistance islands and encode multiple putative ARGs. This report represents the first clonal subtype information and genomic characterization of MDR A. baumannii in the country of Georgia and may inform future epidemiological investigations.

AbstractRoot-associated fungi and bacteria play a pivotal role in the plant –soil ecosystem by influencing both plant growth and immunity. The aim of this study was to unravel the biodiversity of the bacterial and fungal rhizosphere (RS) and rhizoplane (RP) microbiota of Zhukovskij rannij potato (Solanum tuberosum L.) cultivar growing in the Alfisol of Tatarstan, Russia. To assess the structure and diversity of microbial communities, we employed the 16S rRNA and internal transcribed spacer gene library technique. Overall, sequence analysis showed the presence of 3982 bacterial and 188 fungal operational taxonomic uni…

In this study, gold nano-star was synthesized and used for bio-conjugation with pDNA toward the detection of target sequences. Synthesized probe (5ʹ TTG TGA ACT ATT TAC GTC AGC ATG C3ʹ) of Acinetobacter baumannii was found with excellent sensitivity. After the hybridization of pDNA with cDNA, target DNA (5ʹ GCA TGC TGA CGT AAA TAG TTC ACA A 3ʹ) was easily measured. According to ultra-sensitivity of the engineered optical DNA-based bio-assay, it is potentially applied in the bacterial detection of the environmental and clinical specimens. Here, the selection of engineered biosensor in the presence of two mismatch sequen…

ConclusionsTherapeutic drug monitoring-guided meropenem may be a sound new therapeutic option in eradicating multidrug resistant Acinetobacter and offer a novel therapeutic option in the field of personalized medicine.

This study investigated the effect of phytic acid and lysozyme on the microbial composition and quality of grass carp (Ctenopharyngodon idellus) fillets stored at 4 °C. The control, 0.5 mg/mL lysozyme-treated fillets (T1), 0.5 mg/mL phytic acid-treated fillets (T2) and 0.25 mg/mL lysozyme + 0.25 mg/mL phytic acid-treated fillets (T3) were evaluated based on sensory assessment, biogenic amines, ATP-related compounds, total volatile basic nitrogen (TVB-N), and total viable counts (TVC). Changes in microbial composition were analyzed using high-throughput sequencing. Results showed that phytic acid and lyso…

In this study, sufu samples were periodically collected during the whole fermentation to investigate the dynamic changes of fungal and bacterial communities using high-throughput sequencing technology. The overall process can be divided into pre- and post-fermentation. During post-fermentation, the pH value showed a gradual decrease over time while the amino nitrogen content increased. Trichosporon, Actinomucor and Cryptococcus were the main genera in pre-fermentation while Monascus and Aspergillus were dominant in post-fermentation. This huge shift in fungal composition was caused by process procedure of pouring dressing …

One of the most important challenges facing medical science is to better understand the cause of neuronal pathology in neurodegenerative diseases. Such is the case for Huntington’s disease (HD), a genetic disorder primarily caused by a triplet expansion in the Huntingtin gene (HTT). Although aberrant HTT is expressed from embryogenesis, it remains puzzling as to why the onset of disease symptoms manifest only after several decades of life. In the present study, we investigated the possibility of microbial infection in brain tissue from patients with HD, reasoning that perhaps mutated HTT could be deleterious for immu…

This study aimed to target adeB gene with antisense peptide nucleic acid (PNA) and investigate its effect on resistance to antibiotics. NCBI database was used to design appropriate PNA to target adeB gene, by connecting PNA to mRNA, the translation of mRNA can be prevented. Three clinical isolates and A. baumannii ATCC 17978 were treated with the designed PNA by electroporation and competence procedure. Minimum Inhibitory concentration (MIC) of ciprofloxacin, colistin, and tetracycline were determined by microbroth dilution method. In addition, the expression level of adeB gene was measured by quantitative real-time PCR (q…

ConclusionsThis study shows that the alveolar microbiota profile in BAL samples from TB and IP patients, representing infectious and non-infectious lung diseases, respectively, is characterized by decreased diversity.
