Journal: New Potential Pharmacological Targets of Plant-Derived Hydroxyanthraquinones from Rubia spp. (Pubmed Central) - Jun 5, 2022 The simultaneous presence of 1-OH and 3-COOH substituents in the anthraquinone scaffold were emphasized as relevant features for the binding modes' variability and ability of the compounds to strongly bind in the DNA-enzyme complexes. The results reveal new potential pharmacological targets of the studied polyphenols and help in their prioritization as drug candidates and dietary supplements.

Pneumococcal Carriage Among Children After Long-Term Routine 10-Valent Pneumococcal Conjugate Vaccine Use in Brazil (Exhibit and Poster Hall) - Jun 4, 2022 - Abstract #ASMMicrobe2022ASM_Microbe_3412; The 30 (28.6%) erythromycin-resistant isolates (MICs of 1 to >256 μg/ml to erythromycin and 2 to >256 μg/ml to azythromycin) displayed the cMLSB (76.7%) or M (23.3%) phenotypes, harboring the erm(B) and/or mef(A/E) genes...Long-term universal childhood PCV10 use has nearly eliminated PCV10 serotypes, but the high frequency of MDR isolates is a concern. Expanding PCV13 use might contribute to reduce the proportion of MDR isolates.

Current clinical practices and personal habits related to COVID-19 pandemic onset may have impacted anovaginal microbiota, leading to GBS colonization rate reduction and different distribution of serotypes during pandemic among GBS colonizing pregnant women in Rio de Janeiro, Brazil. These results indicate the need for continuous surveillance of GBS among pregnant women in our country.

Contribution Of The Predicted Toxin-Antitoxin System HigBA To Persistence, Biofilm Formation, And Virulence In Burkholderia Pseudomallei (Exhibit and Poster Hall) - Jun 4, 2022 - Abstract #ASMMicrobe2022ASM_Microbe_2999; While, interestingly, the predicted toxin HipA (BPSS1584) with a triggering mechanism of growth arrest like BPSL3343 is significantly overexpressed when the mutant is treated with levofloxacin, compared with the WT strain. When the expression of the same genes was tested in other toxin mutant (∆BPSS0390), the toxin was highly repressed, suggesting a cross-talked among systems that could explain the redundancy of those gene pairs.

Comparative In Vitro Activities of Omadacycline Against Mycoplasma Genitalium (Exhibit and Poster Hall) - Jun 4, 2022 - Abstract #ASMMicrobe2022ASM_Microbe_2809; One clinical isolated detected at UAB in 2019 had elevated MICs to AZI (2), LEV (16), MOX (2), DOX (2) and TET (16), but MICs for OMC (0.125), and MIN (0.5) remained low. These data suggest that OMC may be a potential treatment alternative and warrants further investigation for MG infections that do not respond to other agents.
- |||||||||| The Prevalence And Antibiograms Of Methicillin-resistant Staphylococcus Aureus (mrsa) Isolates From The Anterior Nares Of Apparently Healthy Medical Students In Dominica (Exhibit and Poster Hall) - Jun 4, 2022 - Abstract #ASMMicrobe2022ASM_Microbe_2744;
However, susceptibility was observed to gentamycin (92%), cotrimoxazole (sulfamethoxazole-trimethoprim) (77%), levofloxacin (69%), vancomycin (65%), doxycycline (65%), and tetracycline (62%)...The MRSA prevalence rate of 88.5% observed in the nasal cavities of the medical students is alarming and highlights the need for further investigation to confirm the mechanisms of resistance due to the detection of vancomycin-resistance, and for infection control measures to prevent MRSA transmission from medical students within the community or to vulnerable patients in clinical settings. Interestingly, findings from the isolates’ antibiotic susceptibilities suggest possible treatment of potential patients infected with the nasal MRSA strains with some common antibiotics in the country’s formulary.

The present investigation emphasizes the epidemiological significance of PFGE typing in the detection of emerging strains of highly virulent and multidrug-resistant S. Weltevreden and S. Enteritidis in non-diarrhoeic pigs that pose serious public health implications in the pork supply chain environment. More extensive longitudinal study is warranted to provide epidemiological links between environmental reservoirs and animal and human infections in piggery settings.

Journal: Fast photo-Fenton-like oxidation in bismuth catalysis: A novel Fe(III) self-doped sodium bismuthate nanosheet. (Pubmed Central) - May 31, 2022 Benefited from the unique layered structure of NBH, the Fe(III) as a variable valence metal ion was explored for enhancing NBH activation of peroxymonosulfate (PMS) to degrade levofloxacin (LVF) in the visible-light catalytic system...It was confirmed that Fe(III) embedded in the NBH via the ion exchange with Na, resulting in lattice oxygen vacancies on the surface of the NBH, after the formation of oxygen defect sites, reacts with PMS in the solution to produce active oxygen species with oxidizing efficiency. This study expands the technological application of NBH in the catalytic oxidation of variable valence metals, which are essential for the removal of fluoroquinolone antibiotics.

Journal: Antimicrobial Dispensing Practice in Community Pharmacies in Russia during the COVID-19 Pandemic. (Pubmed Central) - May 30, 2022 Antibiotics for systemic use remained the most common antimicrobials, whereas presumably viral upper respiratory tract infections were the main reason for their purchase. COVID-19 infection itself was responsible for a small proportion of the supply of antimicrobial agents, but systemic antibiotics accounted for more than a half of supplies.

Journal: Pulmonary Targeting of Levofloxacin Using Microsphere-Based Dry Powder Inhalation. (Pubmed Central) - May 30, 2022 Furthermore, LVX-loaded microspheres prolonged drug residence time in the lung and maintained a relatively high drug concentration for a longer time, which contributed to a reduced leakage in the systemic circulation. In conclusion, inhalable LVX-loaded microspheres might represent a plausible delivery vehicle for targeting pulmonary tuberculosis via enhancing the therapeutic efficacy of LVX while minimizing its systemic off-target side effects.

In general, susceptibility to vancomycin and metronidazole of clinical C. difficile in China is high, however, some resistance to metronidazole have recently been reported...The diverse molecular types of C. difficile in China merit further epidemiological, genomic and evolutionary investigation. While the use of probiotics in preventing C. difficile infection (CDI) have received both support and opposition, the discovery of new probiotics and new formulations are showing promising results in combating the threat posed by CDI.

Analysis of Microbial Contamination in Aerosol Facemasks During Nebulized Treatment at the Microbiome Scale (Lounge and Learn 4) - May 21, 2022 - Abstract #ASMMicrobe2022ASM_Microbe_2035; Antibiotic treatment with levofloxacin reduced contamination of the facemasks by oral microbiota, likely due to inhibition of oral microbiota by levofloxacin, representing the first report on the linkage between antibiotic treatment and microbial contamination of medical devices. These findings are of significance in the development of effective strategies for the prevention and mitigation of microbial contamination of aerosol facemasks by eliminating contamination from potential sources and targeted inactivation of specific pathogens.
