Biogenic silver nanomaterials synthesized from leaf extract exhibiting robust antimicrobial and anticancer activities: Exploring the therapeutic potential.

There is a surge in antibiotic consumption because of the emergence of resistance among microbial pathogens. In the escalating challenge of antibiotic resistance in microbial pathogens, silver nanoparticles (AgNPs)-mediated therapy has proven to be the most effective and alternative therapeutic strategy for bacterial infections and cancer treatment. This study aims to explore the potential of OsAgNPs derived from aqueous leaf extract as antimicrobial agents and anticancer drug delivery modalities.

Molecular Screening of Carbapenem-Resistant (CRKP) Clinical Isolates for Concomitant Occurrence of Genes (CTX-M, TEM, and SHV) in the Kingdom of Bahrain.

The emergence of extended-spectrum β-lactamase-producing , including CRKP infections, has resulted in significant morbidity and mortality worldwide. We aimed to explore the presence of genes (CTX-M, TEM, and SHV) in CRKP isolates. A total of 24 CRKP isolates were randomly selected from the Salmaniya Medical Complex Microbiology Laboratory.

Structural evidence of the conversion of nitric oxide (NO) to nitrite ion (NO) by lactoperoxidase (LPO): Structure of the complex of LPO with NO at 1.89 Å resolution.

Lactoperoxidase (LPO) is a heme containing mammalian enzyme which uses hydrogen peroxide (HO) to catalyze the conversion of substrates into oxidized products. LPO is found in body fluids and tissues such as milk, saliva, tears, mucosa and other body secretions. The previous structural studies have shown that LPO converts substrates, thiocyanate (SCN) and iodide (I) ions into oxidized products, hypothiocyanite (OSCN) and hypoiodite (IO) ions respectively.

Evolution and implementation of One Health to control the dissemination of antibiotic-resistant bacteria and resistance genes: A review.

Antibiotic resistance is a serious threat to humanity and its environment. Aberrant usage of antibiotics in the human, animal, and environmental sectors, as well as the dissemination of resistant bacteria and resistance genes among these sectors and globally, are all contributing factors. In humans, antibiotics are generally used to treat infections and prevent illnesses.

Clinical carbapenem-resistant isolates simultaneously harboring , types and qnrS genes from the Kingdom of Bahrain: Resistance profile and genetic environment.

The prevalence of Carbapenem-resistant (CRKP) is currently increasing worldwide, prompting WHO to classify it as an urgent public health threat. CRKP is considered a difficult to treat organism owing to limited therapeutic options. In this study, a total of 24 CRKP clinical isolates were randomly collected from Salmaniya Medical Complex, Bahrain.

Proteomic Analysis of the Colistin-resistant Clinical Isolate: Explorations of the Resistome.

Background: Antimicrobial resistance is a worldwide problem after the emergence of colistin resistance since it was the last option left to treat carbapenemase-resistant bacterial infections. The mcr gene and its variants are one of the causes for colistin resistance. Besides mcr genes, some other intrinsic genes are also involved in colistin resistance but still need to be explored.

Structural evidence of the oxidation of iodide ion into hyper-reactive hypoiodite ion by mammalian heme lactoperoxidase.

Lactoperoxidase (1.11.1.

Potassium-induced partial inhibition of lactoperoxidase: structure of the complex of lactoperoxidase with potassium ion at 2.20 Å resolution.

Lactoperoxidase, a heme-containing glycoprotein, catalyzes the oxidation of thiocyanate by hydrogen peroxide into hypothiocyanite which acts as an antibacterial agent. The prosthetic heme moiety is attached to the protein through two ester linkages via Glu258 and Asp108. In lactoperoxidase, the substrate-binding site is formed on the distal heme side.

Structure of Yak Lactoperoxidase at 1.55 Å Resolution.

Lactoperoxidase (LPO) is a heme containing oxido-reductase enzyme. It is secreted from mammary, salivary, lachrymal and mucosal glands. It catalyses the conversion of thiocyanate into hypothiocyanate and halides into hypohalides.

Co-existence of blaNDM-1 and blaVIM-1 producing Moellerella wisconsensis in NICU of North Indian Hospital.

Infections caused by carbapenemase-producing Enterobacteriaceae have become a major threat to public health, worldwide. Here we report clinically significant NDM-1 and VIM-1 producing Moellerella wisconsensis which has not yet been described in the literature; this is the first report of M. wisconsensis strain harbouring blaNDM-1 and blaVIM-1, recovered from the rectal swab of a low birth weight female child admitted in NICU of the north Indian tertiary care hospital.

Outbreak of Efficiently Transferred Carbapenem-Resistant -Producing Gram-Negative Bacilli Isolated from Neonatal Intensive Care Unit of an Indian Hospital.

The emergence of particularly in Gram-negative bacteria is a burden on the health care system in developing countries. Hence, this study was initiated to screen New Delhi Metallo-β-lactamase (NDM)-producing Gram-negative bacterial strains from neonatal intensive care unit (NICU) of an Indian Hospital. A total of 18 -producing isolates were detected in the present study.

Genetic polymorphisms associated with obesity and non-alcoholic fatty liver disease in Asian Indian adolescents.

Background The objective of this study was to investigate the association of polymorphisms in four genes, tumor necrosis factor-α (TNFA), patatin-like phospholipase domain containing 3 (PNPLA3), adiponectin (ADIPOQ) and apolipoprotein C3 (APOC3), with obesity and non-alcoholic fatty liver disease (NAFLD) in Asian Indian adolescents. Methods In this case-control study, 218 Asian Indian adolescents with overweight/obesity and 86 lean healthy adults without fatty liver were enrolled. Hepatic steatosis was assessed and graded by ultrasonography (USG).

Molecular characterization of novel sequence type of carbapenem-resistant New Delhi metallo-β-lactamase-1-producing Klebsiella pneumoniae in the neonatal intensive care unit of an Indian hospital.

Emergence of multi-drug resistance, especially carbapenem-resistant Klebsiella pneumoniae (CRKP) is a major threat to public health. The aim of this study was to characterize CRKP isolates from infants admitted to the Neonatal Intensive Care Unit (NICU) to find the clonal outbreak of New Delhi metallo-β-lactamase (NDM) producers. In this study 17 CRKP isolates were analysed.

Occurrence of Variants Among Enterobacteriaceae From a Neonatal Intensive Care Unit in a Northern India Hospital.

Carbapenem-resistance among enterobacteriaceae has become a global health concern. The objective of this study was to understand NDM producing enterobacteriaceae and their genetic basis of resistance, spreading in neonatal intensive care unit. Carbapenem resistant NDM producing enterobacteriaceae isolates were recovered from rectal swab and blood sample of infants admitted in NICU.

CRISPRi Induced Suppression of Fimbriae Gene () of a Uropathogenic : An Approach to Inhibit Microbial Biofilms.

Urinary tract infection (UTI) is one the common infections caused by the recalcitrant nature of biofilms, developed after the pathogen has adhered to the inner lining of the urinary tract. Although significant research has been made in recent years to control these types of infection, but as of yet, no approach has sufficiently been able to reduce the prevalence of UTIs. The main objective of this study was to prevent UTIs through targeting the fimH gene, which is the major virulent factor responsible for biofilm formation.

Carbapenamase producers were determined by Carba NP phenotype biochemical assay. Out of 402 isolates, it was the first time three of the isolates were identified as Enterobacter aerogenes carrying bla bla and bla genes.
