Zinc Blockade of SOS Response Inhibits Horizontal Transfer of Antibiotic Resistance Genes in Enteric Bacteria.

Front Cell Infect Microbiol 2018 21;8:410. Epub 2018 Nov 21.

Department of Biochemistry, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, Buffalo, NY, United States.

The SOS response is a conserved response to DNA damage that is found in Gram-negative and Gram-positive bacteria. When DNA damage is sustained and severe, activation of error-prone DNA polymerases can induce a higher mutation rate than is normally observed, which is called the SOS mutator phenotype or hypermutation. We previously showed that zinc blocked the hypermutation response induced by quinolone antibiotics and mitomycin C in and . Read More

Acta Biochim Pol 2018 11 17. Epub 2018 Nov 17.

Dipartimento di Biologia, Università degli Studi di Napoli Federico II. Napoli, Italy.

The major acid-soluble protein components of the mussel Mytilus galloprovincialis sperm chromatin consist of the protamine-like proteins PL-II, PL-III and PL-IV, an intermediate group of sperm nuclear basic proteins between histones and protamines. The aim of this study was to investigate the bactericidal activity of these proteins since, to date, there are reports on bactericidal activity of protamines and histones, but not on protamine-like proteins. We tested the bactericidal activity of these proteins against Gram-positive bacteria: Enterococcus faecalis and two different strains of Staphylococcus aureus, as well as Gram-negative bacteria: Proteus mirabilis, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhmurium, Enterobacter aerogenes, Enterobacter cloacae, and Escherichia coli.

IgG has affinity to protein A, protein G, protein L and glycans on the surface of bacterial cells, and IgG@FeO. It therefore is applicable to the preconcentration of a range of bacterial species.

Impact of Piperacillin/Tazobactam on Nephrotoxicity in Patients with Gram-negative Bacteremia.

Int J Antimicrob Agents 2018 Nov 8. Epub 2018 Nov 8.

Texas Tech University Health Sciences Center, Department of Pharmacy Practice, 5920 Forest Park Rd, Suite 400, Dallas, TX 75235, USA; VA North Texas Health Care System, 4500 S Lancaster, Dallas, TX 75216, USA; University of Texas Southwestern Medical Center, 5323 Harry Hines Blvd., Dallas, Texas 7539, USA. Electronic address:

Piperacillin/tazobactam has been associated with nephrotoxicity in patients receiving vancomycin. Its impact on nephrotoxicity in patients with gram-negative bacteremia (GNB) is unclear. This study aims to evaluate piperacillin/tazobactam's impact on nephrotoxicity in patients with GNB. Read More

Analysis of bacteriological pollution and the detection of antibiotic resistance genes of prevailing bacteria emanating from pig farm seepage.

Microbiologyopen 2018 Nov 9:e737. Epub 2018 Nov 9.

Gastro intestinal Microbiology and Biotechnology, Agricultural Research Council- Animal Production, Irene, South Africa.

Management and disposal of pig farm seepage constitute a serious environmental challenge, and seepage discharge from agricultural waste-water is considered to be one of the greatest contributors of organic substances, bacterial pathogens, and antibiotic resistance genes into the environment. The objectives of this study were to assess the level of bacteriological pollution and to identify the resident antibiotic-resistant genes of culturable bacteria from a studied pig farm seepage. Enumeration of the viable bacterial cell of plated bacteria suspensions (10 to 10  cfu/mL) was performed; also, identification of pure bacterial colonies was done using an API 20E bacterial identification kit.

Identification of AGI1-A, a variant of Acinetobacter genomic island 1 (AGI1), in a French clinical isolate belonging to the Enterobacter cloacae complex.

J Antimicrob Chemother 2018 Nov 8. Epub 2018 Nov 8.

Laboratory of Bacteriology, University Hospital of Dijon, Plateau technique de Biologie, BP 37013, Dijon cedex, France.

Objectives: To characterize the structure of a variant of Acinetobacter genomic island 1 (AGI1) in the Enterobacter cloacae clinical isolate EclC2185 responsible for an 8 year outbreak in Dijon University Hospital.

Methods: The genome was sequenced (Miseq) and de novo assembled (Velvet). PCR and Sanger sequencing were performed to determine the sequence of the genomic island. Read More

Non-native autoinducer analogs capable of modulating the SdiA quorum sensing receptor in serovar Typhimurium.

Beilstein J Org Chem 2018 17;14:2651-2664. Epub 2018 Oct 17.

Department of Chemistry, University of Wisconsin-Madison, 1101 University Avenue, Madison, WI 53706, USA.

Quorum sensing (QS) allows many common bacterial pathogens to coordinate group behaviors such as virulence factor production, host colonization, and biofilm formation at high population densities. This cell-cell signaling process is regulated by acyl L-homoserine lactone (AHL) signals, or autoinducers, and LuxR-type receptors in Gramnegative bacteria. SdiA is an orphan LuxR-type receptor found in genera that responds to AHL signals produced by other species and regulates genes involved in several aspects of host colonization. Read More

Visualization-assisted binning of metagenome assemblies reveals potential new pathogenic profiles in idiopathic travelers' diarrhea.

Microbiome 2018 Nov 8;6(1):201. Epub 2018 Nov 8.

J. Craig Venter Institute, 4120 Capricorn Lane, La Jolla, CA, 92037, USA.

Background: Travelers' diarrhea (TD) is often caused by enterotoxigenic Escherichia coli, enteroaggregative E. coli, other bacterial pathogens, Norovirus, and occasionally parasites. Nevertheless, standard diagnostic methods fail to identify pathogens in more than 40% of TD patients. Read More

The mortality burden of multidrug-resistant pathogens in India: a retrospective observational study.

Clin Infect Dis 2018 Nov 8. Epub 2018 Nov 8.

Center for Disease Dynamics, Economics & Policy, Washington, DC, USA.

Background: The threat posed by antibiotic resistance is of increasing concern in low- and middle-income countries (LMICs) as their rates of antibiotic use increase. However, an understanding of the burden of resistance is lacking in LMICs, particularly for multi-drug resistant (MDR) pathogens.

Methods: We conducted a retrospective, ten hospital study of the relationship between MDR pathogens and mortality in India. Read More
