Abstract
Parasites need necessary and timely adaptations that guarantee their survival in its
challenging environment which may be external or internal to the host. The adaptations
can be morphological, nutritional, life cycle, immunological or biochemical. These
adaptations are the sharp weapons used by the small parasites to fight against the harsh
environment surrounding it. Thorough analysis of these adaptations is the need of the hour
to understand the weak points of the parasites. This will help us to design a better control
strategy as well as to modify the existing control measures against them.
