Omics Approaches in Veterinary Parasitology: Diagnosis, Biomarkers, and Drug Development explores applications of omics approaches for diagnosis, biomarker discovery, and drug development against parasites of veterinary importance. It presents the fundamental principles of parasite biology and their complex physiological processes. The chapters review key aspects such as parasite life cycles, host–parasite interactions, and the molecular mechanisms that underlie parasitic diseases. The subsequent chapters delve into the principles and applications of genomics, transcriptomics, proteomics, and metabolomics in understanding parasites at a molecular level. The use of next-generation sequencing, PCR-based assays, and metagenomics in identifying and characterizing parasites for accurate and efficient diagnosis are also covered in detail. Toward the end, the book focuses on target identification, drug repurposing, and the optimization of drug efficacy while minimizing drug resistance using omics data. The book is useful for researchers, students, and professionals in the field of veterinary parasitology.
