Characterizing the bacteriophage PKp-V1 as a potential treatment for ESBL-producing hypervirulent K1 ST258 isolated from veterinary specimens.

Background And Aim: The dearth of new antibiotics necessitates alternative approaches for managing infections caused by resistant superbugs. This study aimed to evaluate the lytic potential of the purified bacteriophage PKp-V1 against extended-spectrum β-lactamase (ESBL) harboring hypervirulent (hvKp)-K1 recovered from veterinary specimens.

Materials And Methods: A total of 50 samples were collected from various veterinary specimens to isolate , followed by antimicrobial susceptibility testing and molecular detection of various virulence and ESBL genes.

Adenosine A2AR in viral immune evasion and therapy: unveiling new avenues for treating COVID-19 and AIDS.

Adenosine is a neuro- and immunomodulator that functions via G protein-coupled cell surface receptors. Several microbes, including viruses, use the adenosine signaling pathway to escape from host defense systems. Since the recent research developments in its role in health and disease, adenosine and its signaling pathway have attracted attention for targeting to treat many diseases.

Designing a multiepitope mRNA-based vaccine against enterotoxigenic infection in calves: Immunoinformatics and molecular modeling approach.

Background: is one of the serious pathogens causing various infections in the animal field, such as neonatal calf diarrhea, which is responsible for mortality associated with diarrhea during the first days of life.

Aim: Current work is aimed at designing an effective and safe multiepitope vaccine candidate against infection in calves based on the fimbrial protein K99 of Enterotoxigenic (ETEC) and Immuno-informatics.

Methods: A conserved sequence of K99 protein was generated, and then highly antigenic, nonallergic, and overlapped epitopes were used to construct a multiepitope vaccine.

The Rising Tide of Antibiotic Resistance: A Study on Extended-Spectrum Beta-Lactamase and Carbapenem-Resistant Escherichia coli and Klebsiella pneumoniae.

Background: The global spread of extended-spectrum beta-lactamase (ESBL)-producing and carbapenem-resistant Enterobacterales (CRE) poses a significant concern. Acquisition of antimicrobial resistance genes leads to resistance against several antibiotics, limiting treatment options. We aimed to study ESBL-producing and CRE transmission in clinical settings.

Antibacterial efficacy of indigenous Pakistani honey against extensively drug-resistant clinical isolates of Salmonella enterica serovar Typhi: an alternative option to combat antimicrobial resistance.

Background: Extensively drug-resistant (XDR) Salmonella enterica serovar Typhi (S. Typhi) poses a grave threat to public health due to increased mortality and morbidity caused by typhoid fever. Honey is a promising antibacterial agent, and we aimed to determine the antibacterial activity of honey against XDR S.

Antibiotic-Resistant Bacteria, Antimicrobial Resistance Genes, and Antibiotic Residue in Food from Animal Sources: One Health Food Safety Concern.

Antibiotic-resistant bacteria causing foodborne serious illnesses can be found in contaminated food. Therefore, this study aimed to identify the pathogens, genes, and antimicrobial residues present in raw milk and meat. We collected 40 raw milk and 40 beef samples using the aseptic method from various parts of the Faisalabad metropolis, Pakistan.

New insights into geraniol's antihemolytic, anti-inflammatory, antioxidant, and anticoagulant potentials using a combined biological and in silico screening strategy.

The study aims to assess the antihemolytic and antioxidant activities of geraniol versus 2, 2'-azobis, 2-amidinopropane dihydro-chloride- (AAPH-) induced oxidative damage and hemolysis to erythrocytes and its anti-inflammatory potential against lipopolysaccharide- (LPS-) induced inflammation in white blood cells (WBCs) with a focus on its integrated computational strategies against different targeted receptors participating in inflammation and coagulation. The rats' erythrocyte suspension was incubated with different geraniol concentrations. Molecular docking and simulation were used to explore the possible interaction patterns of geraniol against the potential targeted proteins for therapeutic screening.

Impact of bio-nanogold on seed germination and seedling growth in Pennisetum glaucum.

Nanotechnology is leading towards the development of low cost applications to improve the cultivation and growth of plants. The use of nanotechnology in agriculture will leads to a significant effect on food industry along with opening a new area of research in agroecosystem. In this paper gold nanoparticles were biosynthesized with Cassia auriculata leaf extract at room temperature and characterized by UV-vis spectroscopy, X-ray diffraction and transmission electron microscopy.

Development of bioconjugate from Streptomyces tyrosinase and gold nanoparticles for rapid detection of phenol constituents.

Most of the phenol compounds are toxic and have been considered as hazardous pollutants. Several physicochemical and biological methods are available to detect and monitor the phenol pollutants in water and soil. In the present study, phenol constituents of winery, paper and plastic industrial effluents were successfully detected employing tyrosinase-gold nanoparticles bioconjugate.

Production and cytotoxicity of extracellular insoluble and droplets of soluble melanin by Streptomyces lusitanus DMZ-3.

A Streptomyces lusitanus DMZ-3 strain with potential to synthesize both insoluble and soluble melanins was detected. Melanins are quite distinguished based on their solubility for varied biotechnological applications. The present investigation reveals the enhanced production of insoluble and soluble melanins in tyrosine medium by a single culture.
