Molecular Identification of OXA Carbapenemase-Encoding Genes in Isolated from Patients in Critical Care in Egypt.

The emergence of carbapenem-resistant (CRAB) in hospitals, particularly within critical care units, has garnered substantial global concern. CRAB commonly arises from the degradation by various ß-lactamases. : We aimed to assess OXA-type carbapenemases in clinical isolates of obtained from an Egyptian tertiary care facility.

Biodegradation of polystyrene nanoplastics by Achromobacter xylosoxidans M9 offers a mealworm gut-derived solution for plastic pollution.

Nanoplastics pose significant environmental problems due to their high mobility and increased toxicity. These particles can cause infertility and inflammation in aquatic organisms, disrupt microbial signaling and act as pollutants carrier. Despite extensive studies on their harmful impact on living organisms, the microbial degradation of nanoplastics is still under research.

Prevalence of resistance and toxin genes in community-acquired and hospital-acquired methicillin-resistant clinical isolates.

Objectives: Methicillin-resistant (MRSA) is one of the major health hazards and became of greater public health concern since the emergence of community-acquired MRSA. This work aimed to study the prevalence of , , , -PV, -PV (PVL), I, and II genes among community-acquired (CA) hospital-acquired (HA) MRSA to increase vigilance in the diagnosis and management of suspected infections.

Materials And Methods: isolates recovered from clinical samples were classified into community or hospital-acquired and tested for their antibiotic susceptibility against 19 antibiotics.

Growth Promotion of by UAE1, an Endophytic 1-Aminocyclopropane-1-Carboxylic Acid Deaminase-Producing Actinobacterial Isolate.

is a promising halophytic crop for saline soils in semi-arid regions. This study was designed to characterize isolates of endophytic actinobacteria from roots and evaluate the effects associated with plant growth promotion. Twenty-eight endophytic isolates obtained from surface-sterilized roots of were initially selected based on their production of 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase in a chemically defined medium.

Biogenic production of silver nanoparticles by Enterobacter cloacae Ism26.

A bacterial isolate capable of tolerating 30 mM silver nitrate (AgNO3) was recovered from soil contaminated with industrial waste. The isolate was identified by 16S rRNA as Enterobacter cloacae Ism26 (KP988024) and its capability to synthesize silver nanoparticles (AgNPs) was investigated. AgNPs were produced by mixing 1 mM AgNO3 solution with bacterial cell lysate under light conditions.

Design and Synthesis of New Phthalazinone Derivatives Containing Benzyl Moiety with Anticipated Antitumor Activity.

The acetohydrazide derivative reacted with carbon electrophiles such as acid chlorides, acetylacetone, ethyl acetoacetate and aromatic aldehydes to give some interesting heterocyclic compounds. The hydrazide derivative reacted with acetophenone which in turn underwent Vielsmeier-Haack reaction. Also, the phthalazinethione has been synthesized and its behavior towards hydrazine hydrate, oxidizing agent and ethyl chloroacetate has been investigated.
