“…Recently, the worldwide use of nanotechnology in medical science gained the main interest of clinicians (Hassanen et al 2019;Khalaf et al 2019). In developing countries, animal wealth represents the most significant importance in human life via food security supplication (Hassan et al 2020b(Hassan et al , 2022. Hence, the problem of the disease due to bacterial and fungal pathogens are resulted in several infections and immunity disorders such as mycosis and mastitis (Hassan et al 2020c(Hassan et al , 2021(Hassan et al , 2022, diarrhea (Fagiolo et al 2005), pulmonary diseases (Quinn et al 2002), fungal diarrhea and pneumonia (Hassan et al 2011;.…”

“…Several authors reported that these infections resulted from the prolonged use of antibiotics, which caused multidrug resistance (MDR) among infectious pathogens (Williams 2000;Jeykumar et al 2013;Alghuthaymi et al 2021). This MDR can spread widely between pathogens (Daka and Yihdego 2012;Hassan et al 2022). However, the MDRG (multidrug resistance genes) have been progressively sequenced and transmitted among microbial pathogens resulting in a significant public health threat (Roca et al 2015).…”

“…Furthermore, the fluconazole resistance (ERG11) gene has been detected during treatment of fungal infections (Rosana et al 2015;Fahmy et al 2020). Therefore, new effective drugs that can manipulate the MDRG are urgently required to be used (Singh et al 2018;Hassan et al 2022). Nano-sized materials of metals have emerged as a new approach for detecting efficient agents for resolving the drugs resistance problem to traditional antibiotics (Hassan et al 2021;2022;Alghuthaymi et al 2021).…”

Nowadays there is a worldwide problem in the control of animal diseases due to the multidrug resistance of pathogens. Fecal samples, pharyngeal swabs, and rations were examined for cases of respiratory and diarrhea infections in calves. The most predominant species were A. flavus and E. coli pathogens. The drug-resistance against A. flavus and E. coli was tested. Nanotechnology was used and evaluated to overcome the drug resistance to conventional drugs. Herein, ZnONPs and CuNPs were used instead of commercial antibiotics against A. flavus and E. coli pathogens. They suppressed the growth and viability of A. flavus and E. coli sp., and the MIC was (600μg/mL). In addition, the molecular detection of virulent genes such as A. flavus (aflR) and E. coli (stx1) confirmed their conventional identification. In addition, the isolates were PCR tested for multidrug resistance (MDR) genes using primers for the Azole resistance gene (CYP51) in A. flavus and ampicillin resistance gene (CITM) in E. coli. The treated isolates with ZnONPs and CuNPs at high doses, 600μg/mL and 150μg/mL, eliminated the signals of DNA bands of MDR genes, respectively. Whereas the expression of genes was observed with the treatment of E. coli and A. flavus with low doses of 100 and 50μg/mL of ZnONPs and CuNPs, respectively. The exposure of pathogens to high doses of ZnONPs and CuNPs (600 and 150μg/mL) prevents mutation of the azole resistance gene (CYP51) in fungi and ampicillin resistance gene (CITM) in bacteria. Hence, the supplementation of ZnONPs and CuNPs for rations can inhibit the microbial viability and removal of drugs resistant genes.

Lactobacillus plantarum is available in several probiotic products due to its proven abilities in reducing inflammatory bowel disease, the irritable bowel syndrome and preventing diarrhea.Application to Diptera and Lepidoptera showed effects of Lb. plantarum on host development and performance raising questions about application to other insect Orders. Research objectives and outline of this thesisThe purpose of this thesis is to provide a broad overview of T. molitor symbionts, conduct experimental studies focused on potential application of beneficial symbionts such as Pediococcus pentosaceus KVL B19-01 and Lactobacillus plantarum WJB as potential probiotic strains for decreasing the risk of infections in mass-rearing conditions and for optimizing the quality of the chemical composition of the larvae as they may be consumed as feed and food, representing one of the solutions for upscaling the value of by-products along the food chain.Chapter 2 provides a review of the potential of probiotic applications in mass-reared insects. Methods of isolation, identification and production of probiotic bacterial species are provided, taking into consideration methods of their application in an insect mass-rearing context and the important connections between host-microbiota and provided feed in health preservation and disease management.Chapter 3, provides a review addressing the richness and the variety of interactions between the yellow mealworm and its symbionts, methods of pathogen detection and insights for reducing the risk of pathogen infection in rearing facilities.Chapter 4, is an experimental study focused on T. molitor susceptibility to the entomopathogen Bacillus thuringiensis sv. morrisoni biovar tenebrionis (4AA1) (Btt) in conditions resembling the mass-rearing system environment. The study highlights the direct correlation between entomopathogen load and the yellow mealworm larval growth and mortality. Larvae having higher body mass showed to be more resistant to the pathogen and were not compromised in feed conversion. The data also showed that Btt can persist in the tested conditions suggesting a certain risk for the rearing.Chapter 5, focus on the effects of diet composition and two potential probiotic strains, Pediococcus pentosaceus KVL B19-01 and Lactobacillus plantarum WJB, on performance and microbial community composition of T. molitor larvae affected by the entomopathogens Metarhizium brunneum KVL 12-30 and Bacillus thuringiensis sv. morrisoni biovar tenebrionis (4AA1) single or co-infection.The larvae presented increased growth and survival in case of co-infection when fed with diet supplemented with P. pentosaceus. The bacterial community composition of the larvae was similar in all treatments, indicating that the probiotic strain did not establish at a detectable level in the insect, however, its transient presence improved larval performance in its early developmental stages.In Chapter 6, the effects of diet composition and probiotic provision on T. molitor larval performance and chemical com...
