Amphibian virology

open access: yesVeterinary Clinics of North America: Exotic Animal Practice, 2005
Amphibians are a diverse group of species; much work remains to be done to elucidate the viruses of amphibians. Viral diseases may play an important role in wild and captive amphibian populations. Iridoviruses are a leading cause of wild amphibian mortality events in the United States and are a common cause of amphibian mortality events worldwide.

Cocktail effect of Profenophos and Abamectin on tadpoles of Asian Common Toad (Duttaphrynus melanostictus)

open access: yesCeylon Journal of Science, 2018
Farmers mix two or more pesticides as mixing saves the spraying time and the labour cost and also with the idea that it increases the efficiency. The cocktail effect of two agrochemicals, profenophos and abamectin, was tested on the tadpoles of the Asian
