عنوان انگلیسی Effect of different inactivants and preservatives on the stability of 146S fraction of foot-and-mouth diseases virus
چکیده انگلیسی مقاله Foot-and-mouth disease virus (FMDV) cripples livestock by imparting devastating effects to economy. A good vaccine is the key to stopping it, but due to instability of 146S of FMDV, it is becoming difficult. This is bad because only 146S can fight against disease and its dissociation ultimately leads to decreased potency of vaccine. This study aimed to preserve the integrity of 146S in vaccine using different inactivators and preservatives. Foot-and-mouth Disease virus type ‘O’ was propagated on baby hamster kidney 21 cell lines and inactivated using formalin or binary ethylenimine (BEI). Size exclusion high performance liquid chromatography analysis revealed minimal 146S loss after double inactivation with formalin and BEI. This inactivated virus was further formulated into oil-based vaccine with sodium thiomersal or chloroform as a preservative. Our findings demonstrated that chloroform outperformed thiomersal in maintaining shelf life of vaccine. This claims that the combined approach of double inactivation with formalin and BEI followed by chloroform as preservative offered a promising strategy for developing efficacious FMDV.
