Dear Dr.Mohammad

many diseases are transmitted vertically such as

EDS, Mycoplasmosis , L.L. , A E and Salmonellosis

• Avian encephalomyelitis (AE), Mycoplasma, Salmonella pullorum, Salmonella gallinarum, ND, Infectious anaemia are the major ones and among them, mycoplasmosis and salmonellosis have a great impact on our poultry industry.

Diseases transmitted from eggs to chicks. Including Avian Encephalomyelitis (AE). That is very common and lethal. There is no cure. Infected chicks have to be killed and disposed off safely.

Salmonella is a disease caused by germs that inhabit the ovary and are transmitted to the eggs and then the chicks
