The infestation with parasites plays an important role.
Stressful life, concentration of animals and the presence
of different species in a small living space actuate development,
multiplication and spreading of parasites, which
in nature live in cohabitation with their hosts. All these
factors suppress the immune response in reptiles and
increase the opportunity for viruses, bacteria, yeast and
funguses to cause infections and consequent diseases.
Reptiles may carry diseases, which can be spread to other
animals, other animal species and even to humans [1].
