Phages, formally known as bacteriophages, are viruses that solely kill and selectively target bacteria. They are the most common biological entities in nature, and have been shown to effectively fight and destroy multi-drug resistant bacteria. Namely, when all antibiotics fail, phages still succeed in killing the bacteria and may save a life from an infection. phage has many potential applications in human medicine as well as dentistry, veterinary science, and agriculture.For more information, please contact the following e-mail address: Email: global@qyresearch . com Website: https://www . qyresearch . com

Copy Link [PDF] Molecular and Cellular Biology of Viruses Kindle Viruses interact with host cells in ways that uniquely reveal a great deal about general aspects of molecular and cellular structure and function. Molecular and Cellular Biology of Viruses leads students on an exploration of viruses by supporting engaging and interactive learning. All the major classes of viruses are covered, with separate chapters for their replication and expression strategies, and chapters for mechanisms such as attachment that are independent of the virus genome type. Specific cases drawn from primary literature foster student engagement. End-of-chapter questions focus on analysis and interpretation with answers being given at the back of the book. Examples come from the most-studied and medically important viruses such as HIV, influenza, and poliovirus. Plant viruses and bacteriophages are also incl

Global phage therapy market is expected to foresee a compound annual growth rate of 8.1% from 2021 to 2028. The major factors driving the growth of the phage therapy market are antibiotics resistance, the increased prevalence of food-borne diseases, use of phage therapy in the food & beverage industry, application of bacteriophage specific to target bacteria, extensive research & development, and increasing antimicrobial resistance. Nowadays antibiotics resistance has become one of the biggest threats to global health as it can affect people of any age group.
