Resistance induction in cucumber and direct antifungal activity of zirconium oxide nanoparticles against Rhizoctonia solani.

Zirconium oxide nanoparticles (ZrONPs) were synthesized and evaluated for their ability to induce root rot resistance in cucumber and direct antifungal activity against Rhizoctonia solani. Resistance induction was investigated using real-time polymerase chain reaction (RT-PCR) and the effect of ZrONPs on the growth of cucumber plants was investigated. The results showed that ZrONPs at a concentration level of 100 μg/L significantly inhibited the growth of Rhizoctonia solani (86.

Zinc oxide nanostructures as a control strategy of bacterial speck of tomato caused by Pseudomonas syringae in Egypt.

This study was conducted to evaluate the ability of zinc oxide nanoparticles (ZONPs) with unique properties to protect tomato against the bacterial speck pathogen, caused by Pseudomonas syringae pv. tomato DC3000 (Pst). Protection of tomato against bacterial speck using ZONPS was evaluated by its direct antibacterial activity and its ability for inducing resistance in tomato plants.

Virulence of geographically different Cryptosporidium parvum isolates in experimental animal model.

Cryptosporidium parvum is a coccidian parasite which causes gastrointestinal disease in humans and a variety of other mammalian species. Several studies have reported different degrees of pathogenicity and virulence among Cryptosporidium species and isolates of the same species as well as evidence of variation in host susceptibility to infection. The study aimed to investigate infectivity and virulence of two Cryptosporidium parvum “Iowa isolate” (CpI) and a “local water isolate” (CpW).

Antifungal activity of fabricated mesoporous alumina nanoparticles against root rot disease of tomato caused by Fusarium oxysporium.

Background: The present work involved the synthesis and characterisation of mesoporous alumina sphere (MAS) nanoparticles to evaluate their biological activity against tomato root rot caused by Fusarium oxysporium, as compared with the recommended fungicide, tolclofos-methyl, under laboratory and greenhouse conditions. The effects of MAS nanoparticles on the growth of tomato plants were also evaluated and compared with those of tolclofos-methyl.

Results: The physical characteristics and structural features of MAS nanoparticles, such as their large surface-area-to-volume ratio, active surface sites and open channel pores, caused high antifungal efficacy against F.

Monitoring and remediation of organochlorine residues in water.

This study monitored the presence of organochlorines in drinking water in Kafr-El-Sheikh, Ebshan, Elhamoul, Mehalt Aboali, Fowa, Balteem, and Metobess in the Kafr-El-Sheikh Governorate, Egypt, to evaluate the efficiencies of different remediation techniques (advanced oxidation processes [AOPs] and bioremediation) for removing the most frequently detected compound (i.e., lindane) in drinking water.

Identification and mechanism of Echinochloa crus-galli resistance to fenoxaprop-p-ethyl with respect to physiological and anatomical differences.

Identification and mechanism of Echinochloa crus-galli (L.) resistance to fenoxaprop-p-ethyl via physiological and anatomical differences between susceptible and resistant were investigated. The physiological and anatomical differences that were take into account were growth reduction, chlorophyll content reduction, lamina thickness, and xylem vessel diameter in both susceptible and resistant biotypes of E.

Comparative study between non lethal and lethal strains of Plasmodium yoelii with reference to its immunological aspect.

Innate immunity has an important role in the protection against malaria. To clarify the effect on non lethal and lethal strain of Plasmodium yoelii, comparison between two groups of C57BL/6 mice infected with 10(4) parasitized RBCs was performed. Liver and spleen mononuclear cells were isolated and analyzed by flow cytometry.
