Integrated application of transcriptomics and metabolomics provides insight into the mechanism of Eimeria tenella resistance to maduramycin. Int J Parasitol Drugs Drug Resist 2024; 24:100526. [PMID: 38382267 PMCID: PMC10885789 DOI: 10.1016/j.ijpddr.2024.100526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 01/11/2024] [Accepted: 02/14/2024] [Indexed: 02/23/2024]
Abstract
Avian coccidiosis, caused by Eimeria parasites, continues to devastate the poultry industry and results in significant economic losses. Ionophore coccidiostats, such as maduramycin and monensin, are widely used for prophylaxis of coccidiosis in poultry. Nevertheless, their efficacy has been challenged by widespread drug resistance. However, the underlying mechanisms have not been revealed. Understanding the targets and resistance mechanisms to anticoccidials is critical to combat this major parasitic disease. In the present study, maduramycin-resistant (MRR) and drug-sensitive (DS) sporozoites of Eimeria tenella were purified for transcriptomic and metabolomic analysis. The transcriptome analysis revealed 5016 differentially expressed genes (DEGs) in MRR compared to DS, and KEGG pathway enrichment analysis indicated that DEGs were involved in spliceosome, carbon metabolism, glycolysis, and biosynthesis of amino acids. In the untargeted metabolomics assay, 297 differentially expressed metabolites (DEMs) were identified in MRR compared to DS, and KEGG pathway enrichment analysis indicated that these DEMs were involved in 10 pathways, including fructose and mannose metabolism, cysteine and methionine metabolism, arginine and proline metabolism, and glutathione metabolism. Targeted metabolomic analysis revealed 14 DEMs in MRR compared to DS, and KEGG pathway analysis indicated that these DEMs were involved in 20 pathways, including fructose and mannose metabolism, glycolysis/gluconeogenesis, and carbon metabolism. Compared to DS, energy homeostasis and amino acid metabolism were differentially regulated in MRR. Our results provide gene and metabolite expression landscapes of E. tenella following maduramycin induction. This study is the first work involving integrated transcriptomic and metabolomic analyses to identify the key pathways to understand the molecular and metabolic mechanisms underlying drug resistance to polyether ionophores in coccidia.

The antimicrobial and immunomodulatory effects of Ionophores for the treatment of human infection. J Inorg Biochem 2021; 227:111661. [PMID: 34896767 DOI: 10.1016/j.jinorgbio.2021.111661] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 10/27/2021] [Accepted: 11/03/2021] [Indexed: 12/18/2022]
Abstract
Ionophores are a diverse class of synthetic and naturally occurring ion transporter compounds which demonstrate both direct and in-direct antimicrobial properties against a broad panel of bacterial, fungal, viral and parasitic pathogens. In addition, ionophores can regulate the host-immune response during communicable and non-communicable disease states. Although the clinical use of ionophores such as Amphotericin B, Bedaquiline and Ivermectin highlight the utility of ionophores in modern medicine, for many other ionophore compounds issues surrounding toxicity, bioavailability or lack of in vivo efficacy studies have hindered clinical development. The antimicrobial and immunomodulating properties of a range of compounds with characteristics of ionophores remain largely unexplored. As such, ionophores remain a latent therapeutic avenue to address both the global burden of antimicrobial resistance, and the unmet clinical need for new antimicrobial therapies. This review will provide an overview of the broad-spectrum antimicrobial and immunomodulatory properties of ionophores, and their potential uses in clinical medicine for combatting infection.

Abstract
The experiments were conducted to determine intrasporozoite Na+/K+ concentrations (by AAS) and membrane-bound Na+ -K+ -ATPase activity (measured by UV-VIS with a Na+ -K+ -ATPase Detection Kit) of Eimeria tenella sporozoites of the sensitive line (i.e., the parent line, coded as OS) and 2 resistant lines, derived from the parent line (coded as OR125 and OR200), with and without in vitro exposure to monensin. These parameters for OR125 and OR200 were significantly lower than those for OS. In vitro exposure to monensin increased intrasporozoite Na+/K+ concentrations and Na+ -K+ -ATPase activity, but the stimulation on OS was significantly higher than those on OR125 and OR200, indicating that monensin had less effect on resistant parasites. The results of this study suggest that altered biochemical or physiological properties, or both, in the membranes of E. tenella might be related to a reduced sensitivity to monensin.

Abstract
Resistance has been encountered wherever drugs have been used extensively for the control of parasitic infections. The poultry industry is dependent upon drugs for the control of coccidiosis, a major disease of chickens caused by protozoan parasites of the genus Eimeria. In modern poultry production, drugs are used prophylactically for the prevention of coccidiosis by including them in the diet. This has inevitably led to the development of resistance. We have been fortunate in that new drugs have become available to replace those to which resistance has developed, but this situation is unlikely to continue. The problem of drug resistance, discussed here by David Chapman, has provided impetus for the development of new approaches (such as vaccination) for the control of coccidiosis.
