This book features an in-depth examination of the ongoing problem of bovine mastitis and the potential solutions offered by polymer nanoparticles. With extensive research and analysis, the book delves into the causes and consequences of bovine mastitis, including the shift in the relevance of various infections and the increasing problem of antibiotic resistance. The authors explore the use of nanoparticles as a potential alternative to traditional antibiotics and the importance of tailoring their characteristics for specific uses. Detailed discussions of the pros and cons of different manufacturing procedures and characterizations of bovine mastitis, drug-resistant bacteria, and resistance development make this monograph an invaluable resource for researchers and experts in the field of veterinary medicine, and an excellent resource for those interested in investigating the viability of nano-materials as future antibiotic alternatives.
