Parasite Resistance to Anthelmintics
I have heard that parasites can develop resistance to certain chemicals just like bacteria can. Is this the reason why dewormers are rotated? In addition, how do parasites develop resistance so easily? Is it because they produce quickly and on a large scale? In addition, do they have properties similar to bacteria such as conjugation and other means? Thank you
The remaining population after treatment is resistant and reproduces generations/offsprings that are resistant and becomes the primary population. Mutation for resistance occurs in the population with repeatedly exposure to a chemical, especially in under dosage. . Annual rotation of chemicals reduces risk of developing resistance a population.
