Multimillion dollar poultry industry, always face the threats from emerging/ re-emerging poultry diseases. A major element of disease resistance is the Major Histocompatibility Complex (MHC) and has regions i.e. B-F, B-L and B-G. BF2 is a predominantly expressed class I gene. Red jungle fowl (RJF) is the sole ancestor of all the present day chicken. The divergence between RJF and domestic chicken is presumed to have originated some 8000 years back. During the 8000 years, the chicken genome has undergone tremendous changes due to intentional selection. There is a general consensus among the...

The transmission electron microscope, commonly referred to as a TEM, is more powerful than the traditional light microscope. Transmission electron microscopes allow the user to see the fine details of the specimens which are normally not seen in microscopes of a lower power. The invention of the transmission electron microscope (TEM) enabled scientists to view living material in a way that was previously impossible. Bacteria and other living matter could now be examined on the cellular level through their magnetic structures, allowing scientists to view formation of DNA chains and crystalline...
