Molecular tracking of pathogens in central venous catheter.

CONCLUSION: The molecular method identified more bacteria than microbiological methods and revealed colonization of the catheters. The most commonly found bacteria are in the environment and in the microbiota of the skin, which suggests contamination by the hands of health professionals and points out the need for more efforts in preventive strategies.

la Fecka The purpose of this study was to investigate the composition of leaf extracts from Aronia melanocarpa, Chaenomeles superba, and Cornus mas, and their antimicrobial activity against typical spoilage-causing and pathogenic bacteria found in meat and meat products. The highest total phenolic content (TPC) was detected in C. superba extract, followed by C. mas and A. melanocarpa extracts. The antioxidant capacity of the extracts was measured by DPPH and ABTS assays. The lowest IC50 values were found for C. superba extract, followed by C. mas and A. melanocarpa extracts. LC-MS and HPLC analysis revealed that A. mel...

In this study we designed and synthetized various derivatives of NCR247, including shorter fragments and various chimeric derivatives. The antimicrobial activity of these peptides was tested on the ESKAPE bacteria; Enterococcus faecalis, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Escherichia coli as a member of Enterobacteriaceae and in addition Listeria monocytogenes and Salmonella enterica. The 12 amino acid long C-terminal half of NCR247, NCR247C partially retained the antimicrobial activity and preserved the multitarget interactions with partners of NCR247. Nevert...

In conclusion, wastewater effluents from the investigated poultry slaughterhouses exhibited clinically relevant bacteria (E. coli, MRSA, K. pneumoniae, species of the ACB-and E. cloacae-complexes) that contribute to the dissemination of clinically relevant resistances (i.e. bla CTX-M/SHV, mcr-1) in the environment.Importance Bacteria from livestock may be opportunistic pathogens and carriers of clinically relevant resistance genes, as many antimicrobials are used both in veterinary and human medicine. They may be released into the environment from wastewater treatment plants (WWTPs) that are influenced by wastewater from s...

Publication date: Available online 15 January 2020Source: Microbiological ResearchAuthor(s): Ashley N. Williams, John StavrinidesAbstractMulti-drug resistant Acinetobacter baumannii and Pseudomonas aeruginosa continue to pose a serious health threat worldwide. Two Pantoea agglomerans strains, 3581 and SN01080, produce an antibiotic effective against these pathogens. To identify the antibiotic biosynthetic gene clusters, independent genetic screens were conducted for each strain using a mini-Tn5 transposon, which resulted in the identification of the same conserved eight-gene cluster. We have named this antibiotic Pantoea N...

Conclusion: Sufentanil Citrate, midazolam, and pethidine exerted efficient inhibitory effect on Staph. aureus, Strep. pneumoniae, P. aeruginosa and E. faecalis. Lidocaine and bupivacaine had a strong inhibitory effect on growth of nine standard bacterial species in our survey.

CONCLUSIONS: The key clinically important finding is the rapidly decreasing carbapenem susceptibility among Enterobacteriaceae reported in SA, irrespective of sector. In addition, the analysis provides information that could be used to monitor the effectiveness of interventions implemented at a national level under the guidance and direction of the national AMR framework.

Abstract The threat of diminished antibiotic discovery has global healthcare in crisis. In the United States, it is estimated each year that over 2 million bacterial infections are resistant to first-line antibiotic treatments and cost in excess of 20 billion dollars. Many of these cases result from infection with the ESKAPE pathogens ( Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter sp.), which are multidrug-resistant bacteria that often cause community- and hospital-acquired infections in both healthy and immunocompromised pati...

Abstract Antibiotics, considered as a backbone of modern clinical-medicines, are facing serious threats from emerging antimicrobial-resistance (AMR) in several bacteria from nosocomial and community origins and is posing a serious human-health concern. Recent commitment by the Heads of States at the United Nations General Assembly (UNGA, 2016) for coordinated efforts to curb such infections illustrates the scale of this problem. Amongst the drug-resistant microbes, major threat is posed by the group named as ESKAPEE, an acronym for Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter b...

Conclusion. The hexane extract of L. apiculata leaves showed the lower MIC against S. aureus when compared with extracts obtained from other parts of the plant. The growth curve and the colonies count suggest a bacteriostatic activity of the L. apiculata leaves extract against Staphylococcus aureus. PMID: 31737073 [PubMed]
