Changes in Protein Content in Virus and Bacterial Infected Fifth Instar Larvae of Silkworm, Bombyx Mori L. and Treatment with Antibiotics.
Keywords:
Bombyx mori, virus, bacterial, pre-and post-inoculated, antibiotics.Abstract
Changes in protein level in Haemolymph, Fatbody and Silkgland of the 5th instar silkworm of hybrids, PM x CSR2, CSR4 x CSR2, and CSR2 x CSR4 were examined under inoculation with the viral and bacterial pathogen and treatment with antibiotics in healthy, pre-inoculated and post-inoculated conditions. The results indicate that the changes in protein content in infected larvae could be favourably reverted towards control levels by treatment with antibiotics, both in pre-and post-inoculated conditions. Protein content could be elevated by antibiotic supplementation in healthy larvae. Antibiotic treatment was more effective during post-inoculated conditions than pre-inoculated conditions. Pre-treatment with antibiotics seems to assist in the building up the resistance before the attack of the pathogen, thereby reducing the severity of infection.
