Recently, the extensive use of quinolones led to increased resistance these antimicrobial agents, with different rates according organism and geographical region. The aim this study was detect rate Klebsiella pneumoniae Iraqi isolates toward quinolone determine genetic mutations in gyrA parC, screen for efflux-pump activity, presence plasmid-mediated (PMQR) genes.Forty-three K. were confirmed phenotypically genotypically by Vitek 2 system species specific primers PCR using targeting rpo gene...
Carbapenems are considered the most efficient antibiotic used in treatment of nosocomial infections. Carbapenem-resistant Gram-negative rods becoming a serious hazard hospitals threatening public health. The aim current study was to investigate prevalence carbapenem-resistant pathogens incriminated healthcare-associated infections, along with antimicrobial resistance profiles, carbapenemase and metallo-β-lactamase production, their molecular characterization.A total 186 clinical specimens...
The in vitro callus induction of Solanum incanum L. was executed on MS medium supplemented with different concentrations auxin and cytokinin utilizing petioles explants leaves. highest significant fresh weights from leaf were 4.68 5.13 g/jar for the with1.0 mg L−1 BA 1.0 2,4-D. extract leaves used green synthesis silver nanoparticles (Ag-NPs). Analytical methods Ag-NPs characterization UV-vis spectroscopy, Fourier Transform Infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Transmission...
Bacterial pathogens cause pain and death, add significantly to the expense of healthcare globally, pose a serious concern in many aspects daily life. Additionally, they raise significant issues other industries, including pharmaceuticals, clothing, food packaging. Due their unique properties, great deal attention has been given biogenic metal nanoparticles, nanocomposites, applications against pathogenic bacteria. This study is focused on silver copper nanoparticles composites (UL/Ag2 O-NPS,...
One of the most prevalent chronic infectious disorders is tooth decay. Acids produced when plaque bacteria break down sugar in mouth cause Streptococcus mutans and Lactobacillus acidophilus are prominent species related to dental caries. Innovative biocidal agents that integrate with a biomaterial prevent bacterial colonization have shown remarkable promise as result rapid advancement nanoscience nanotechnology. In this study, Ulva lactuca was used cellulose source reducing agent synthesize...
Zinc oxide nanoparticles have many advantages for nano-biotechnologists due to their intense biomedical applications. ZnO-NPs are used as antibacterial agents, which influence bacterial cells through the rupture of cell membrane and generation reactive free radicals. Alginate is a polysaccharide natural origin its excellent properties that in various Brown algae good sources alginate reducing agent synthesis nanoparticles. This study aims synthesize by using brown alga Fucus vesiculosus...
AIM: This study investigated the antibacterial efficacy of five plant extracts, as well combinations two most effective plant, extracts either with or without commercial varnish (MI varnish) on in vitro growth Streptococcus mutans and Lactobacillus acidophilus comparison to MI using agar disk diffusion broth dilution methods.
 METHODS: Methanolic extractions plants (Cinnamon, Turmeric, Ginger, Clove Black seed,) were tested against oral pathogens. The minimum inhibitory concentration...
Bacillus species are widely distributed microorganisms in nature that responsible for outbreaks of food poisoning and a common cause spoilage. This study aimed to isolate identify foodborne from meat determine the antimicrobial activities commercial essential oils spices powder extracted certain medicinal plants.Sixty samples were collected Assiut city subdivided into raw processed meat. spp isolated identified according their cultural characters, biochemical reactions, serological typing,...
The population structure of Pseudomonas aeruginosa is panmictic-epidemic in nature, with the prevalence some high-risk clones. These clones are often linked to virulence, antibiotic resistance, and more morbidity. clonal success these lineages has been acquisition spread mobile genetic elements. main aim study was explore other molecular markers that explain their global success. A comprehensive set 528 completely sequenced P. genomes analyzed. examined using Multilocus Sequence Typing...
Dental caries is an infectious oral disease caused by the presence of different bacteria in biofilms. Multidrug resistance (MDR) a major challenge dental treatment. Swabs were taken from 65 patients with Makkah, Saudi Arabia. cultivated on mitis salivarius agar and de Man, Rogosa, Sharpe (MRS) agar. VITEK 2 was used for identification isolated bacteria. Antibiotic susceptibility testing performed using commercial antibiotic disks. Ulva lactuca as reducing agent cellulose source to create...
Pathogens resistant to antimicrobials form a significant threat public health worldwide. Tackling multidrug-resistant pathogens via screening metagenomic libraries has become common approach for the discovery of new antibiotics from uncultured microorganisms. This study focuses on capturing nonribosomal peptide synthase (NRPS) gene clusters implicated in synthesis many natural compounds industrial relevance. A NRPS PCR assay was used screen 2976 Escherichia coli clones soil library target...

Balanites aegyptiaca or Desert Date (Zygophyllaceae) is widely distributed in arid and semi-arid regions Africa South Asia. The current study aims to identify the infraspecific variation between B. native Egypt Saudi Arabia. Detailed macro- micromorphological analyses of leaflets, petioles, stems, spines, fruits were performed using a light Scanning Electron Microscope (SEM). Statistical analysis was by relevant R- software packages. Leaflet shape apex, leaflet length/width ratio, indumentum...
Abstract Background The misuse of antibiotics in the last decade led to quick emergence antibiotic resistance among pathogenic microorganisms. It has become a serious health problem that motivates researchers explore new antimicrobial compounds. Micromonospora is one most important producers commercially successful secondary bioactive metabolites, especially such as aminoglycosides, enediynes, and oligosaccharides. This study highlights potential spp. source novel antibacterial agents...
