Comprehensive Statistical Atlas of Diseases in Amphibians (Frogs, Toads, Mimics)
This detailed scientific compilation outlines a complete classification of infectious diseases, non-communicable disorders, parasitic infections, nutritional and vitamin deficiencies, systemic illnesses, and neoplastic conditions affecting amphibians such as frogs, toads, mimics, and other related species. Diseases are cataloged according to organ systems, and structured into comparison tables, enabling in-depth epidemiological and clinical review.
Each disease entry includes:
- English & Latin Name
- Etiological Agent (Virus [enveloped/non-enveloped, morphology], Bacteria [Gram +/−, morphology], Fungi [structure], Parasites [structure])
- Target Organ/System
- Histopathology/Lesions
- Age or Developmental Stage at Infection
- Type of Animal (juvenile, adult, male, female, gravid, incubating, brooding, etc.)
- Seasonality
- Estimated Survival Rate
- Treatment (active pharmaceutical ingredient)
- Vaccination (name, vaccine type if available)

📌 Additional Notes:
- Many amphibian diseases are aggravated by habitat destruction, pollution, and climate variability.
- Probiotic supplements and biosecurity measures in captivity significantly enhance resistance.
- Vaccines for amphibians remain largely experimental or unavailable.
