Purpose: This study aimed to green synthesized copper nanoparticles (CNP) using Lupinus arcticus extract and assess the protoscolicidal effects and the effectiveness of these nanoparticles in experimental animal settings to combat hydatid cysts.

Methods: The protoscolicidal properties of CNP were examined in vitro on hydatid cyst PS via the eosin exclusion assay. The in vivo effectiveness of CNP at doses of 20, 40, and 80 mg/kg/day for 28 days on hydatid cyst-infected mice was determined by assessing the number, size, weight of hydatid cysts the gene expression levels of caspase-3, antioxidant (glutathione peroxidase (GPx) and superoxide dismutase (SOD)) and inflammatory cytokines (Interleukin-4 (IL-4), IL-10, and inducible nitric oxide synthase (iNOS)) in the infected mice were also assessed by Real-time PCE.

Introduction: The camel-infesting tick, , is a prominent ectoparasite in the Middle East and North Africa (MENA) region, critically impacting camel health and acting as a vector for tick-borne pathogens. Despite prior studies on its microbiota, the effects of geographic origin and sex on microbial community structure and functional stability remain poorly understood.

Methods: To address this, we characterized the bacterial microbiota of ticks collected from camels in Tunisia (TUN) and Saudi Arabia (SA) using 16S rRNA gene sequencing, microbial network analysis, and metabolic pathway prediction.

The present in vitro and in vivo study aimed to fabricate and characterize linalool-zinc oxide nanoparticles (Lin-ZNP) and evaluate their effectiveness against Toxoplasma gondii infection in terms of inflammation, oxidative stress, and pathogenicity. Lin-ZNP was synthesized using an ethanolic solution of polyvinyl alcohol. The anti-Toxoplasma and cytotoxicity activities of Lin-ZNP were investigated, along with its effects on nitric oxide (NO) production, caspase-3 activity, and pro-inflammatory genes.

Order Rodentia is the most speciose among mammals and the members of this order are known to host more than 60 zoonotic diseases and rodents are a potential health threat to humans. This study was designed to report the molecular prevalence and phylogenetic evaluation of various blood borne bacterial pathogens (Anaplasma ovis, Anaplasma phagocytophilum, Anaplasma marginale and Bartonella spp.) in the blood samples of four wild rodent species [Meriones rex (N = 27), Acomys dimidiatus (N = 18), Myomys yemeni (N = 6) and Rattus rattus (N = 3)] that were trapped during August till October 2020 from Al Makhwah governorate in Saudi Arabia.
