The distribution of amphibian fauna in Pakistan elevates from sea level reaching up to 4000 meters in the Himalayas and Karakoram, stretching across the latitude from Indian boundary to its western borders [3]. The presence of a long tail and two pairs of limbs of about equal size distinguishes newts and salamanders (order Caudata) from other amphibians, although members of the eel-like family Sirenidae have no hind limbs. The Mediterranean-rim countries hold around 400 million people and 135 million of them live on the coast. A second type of chytrid fungus (Batrachochytrium salamandrivorans, Bsal) is emerging in Europe.While Bsal primarily affects salamanders, frogs can also become infected and spread this .
