Antibacterial effect of biosynthesized silver nanoparticles in Pacific white shrimp Litopenaeus vannamei (Boone) infected with necrotizing hepatopancreatitis bacterium (NHP-B)

The shrimp necrotizing hepatopancreatitis is caused by a pleomorphic Gram-negative Rickettsia-like bacteria known as NHP-B. It is well known that silver is an effective bactericidal, but experiments with aquatic organisms are scarce, even more at nanoparticle level. The objective of this study was t...
