A Study on Corona Virus an Infectious Disease

An experimental study on early pathogenesis of a very mvirulent isolate of infectious bursal disease virus, employing immunohistochemistry

In this study, immunohistochemistry was used to clarify the early stages of viral kinetics and cycliccourse of IBDV, IR499, which has been described earlier as a very virulent strain (vvIBDV). Fifteen, 4-week-old SPF chickens were inoculated with 10³ EID50 of vvIBDV, IR499, via oculo/nasal route. Five birdsserved as controls, and inoculated with phosphate buffered saline (PBS). The birds were t...

Characterization of a Highly Virulent Infectious Bursal Disease Virus

Pathogenicity Study and Restriction Enzyme Profile of a Recently Isolated Infectious Bursal Disease Virus in Iran

The pathogenicity of a recent isolate of Infectious bursal disease virus (IBDV), IR499, isolated from a nonvaccinated flock with 17.5 % mortality rate in susceptible SPF chickens, chickens embryos and broilers was discussed. The molecular characterization of the virus based on the restriction fragment length polymorphism (RFLP) pattern was also investigated. The mortality rates were 85% and 22%...

A comment on the origin of Corona virus

The new coronavirus origin is one of the important controversial subjects in the study of this virus. There are many contradictions about the epidemiological data and bat origin of the virus. In this regard heterodox view by cosmic biology concepts, exceptionally bright fireball event a few months before the outbreak in China, and extraordinary weak solar cycle with many sunspot free days could...
