Abstract Background Nosema ceranae, the predominant microsporidian parasite, weakens Apis mellifera honey bee colonies and reduces their productivity and reproduction. This research aims to detect the impact of thymol and propolis extracts on genotoxicity repair, oxidative enzymes, expression of some antimicrobial genes and some hypopharyngeal gl...

Despite their diminutive size, mosquitoes serve as significant vectors for numerous pathogenic organisms. In this research, five commercial essential oils (EOs) were screened (lemon, camphor, sandalwood, orange, and black pepper oil)against larvae of the filarial vector Culex pipiens to evaluate their larvicidal activity, their effects on different...

Avian malaria is a mosquito-borne disease caused by Plasmodium spp. protozoa. Although these parasites have been extensively studied in North America and Eurasia, knowledge on the diversity of Plasmodium , its vectors and avian hosts in Africa is scarce. In this study, we report on natural malarial infections in free-ranging sparrows ( Passer domes...

Honey bees, vital agricultural pollinators, suffer significant losses due to the pathogen Nosema ceranae. Fumagillin, utilized to prevent nosemosis, poses a hazardous risk. This study aims to investigate the potential of natural thymol and propolis extract in combating Nosema infection in honey bee colonies. The evaluation will be conducted thr...

Background Nosema ceranae, the predominant microsporidian parasite, weakens Apis mellifera honey bee colonies and reduces their productivity and reproduction.

This work aims to compare between the forensic insect species, their succession patterns and decomposition stages of rabbit corpses killed with different methods in Qena city, Egypt. Four experiments were carried out during this study for four successive seasons. Four rabbits were placed in each experiment, the first two rabbits received a double L...

The present work aims to study the biochemical changes of Culex pipiens females infected with Plasmodium cathemerium. For achievement this research, females of Culex pipiens were infected with Plasmodium cathemerium to study the effect of Plasmodium on Culex pipiens females protein profile quantitative and qualitative at 12h, 1d, 4d, 5d and 6d post...

The present work aims to identify, molecular characterization and phylogeny analysis of the induced antibacterial gene, cytochrome oxidase, from the whole body of bacterial-fed fourth instar Cx. pipiens larvae using differential display technique. For achievement this research, the fourth instar Cx. pipiens larvae were fed on gram (+) bacteria, S....

The present work aims to study the changes in protein profile of bacterial-challenged fourth instar Culex pipiens larvae. For achievement this research, fourth larval instars of Culex pipiens were challenged with Gram (+) bacteria, Staphylococcus aureus and gram (bacteria ia, Klebsiella pneumoniae and mix of the two bacterial strains to study the e...
