Chitosan Mitigates Bacterial Infection-induced Metabolic Stress in Silkworms: A Study on Carbohydrate and Amylase Dynamics

Amarnatha, N., Bhuvaneshwar Rajesh Naik, Kruthika M. S., Mamatha, N.S., Humakousar Sangreskop & Naveenkumar, K. · Journal of Advances in Biology & Biotechnology · 2025

Silkworm (Bombyx mori L.) rearing is a cornerstone of India's rural economy but is frequently hampered by infections such as flacherie, caused by Staphylococcus aureus and Bacillus thuringiensis. This study evaluated the influence of silkworm pupal chitosan extracted via deprotei...
