Antonyms are words that are opposite in meaning to another word. Bovine Leukemia Virus Glycoprotein gp is a specific term related to veterinary medicine, and as such, there is no direct antonym for this term. However, there are several related words that may be considered antonyms. For example, instead of focusing on veterinary terms, one could consider the antonyms of "virus" or "glycoprotein." Antonyms of virus could include "antibiotic," "health," or "sterile," while antonyms of glycoprotein could include "amino acid," "carbohydrate," or "inorganic." It is important to note that antonyms are not always direct opposites, but rather words or concepts that are contrasting in nature.
