What is the difference between emerging and re-emerging disease?

World Health Organization said that Germs are the main factor in cases of mastitis in camels.  In addition, some fungi and viruses can cause mastitis in camels as well. The cases of infection of the mastitis are the result of the introduction of germs through the opening of the nipple and some cases, a few, the result of the injury of camels of tuberculosis and brucellosis, where mastitis causes bacteria coming through the blood. The most important bacteria that have been isolated from cases of mastitis in camels, whether milk or skin that surrounds the supplication or the hands of the milking is: (WHO, 2000)

·         Staphylococcusureus, especially Staphylococcus aureus, has been shown to cause significant damage to the tissues of the urethra due to its secretion of many toxins, especially the type of alpha that causes the infection of the mastectomy and then damaged.

·         Streptococcus and have several species.

·          E. coli bacillus (E.coli).

·         Pasteurellass bacteria.

There are a number of other predisposing factors for the infection of camels with mastitis such as the lack of cleanliness of the environment surrounding camels, and the presence of external parasites such as Kurds, scratches or sores, injury of workers who carry camels with infectious diseases, and do not take sterilization of the hands before milking, connecting nipples to prevent breast feeding of milk leads to problems with epilepsy., milking the diseased corpse and then the healthy camel transmits the infection.

(nd, 2014)The clinical symptoms of mastitis include changes in the tissues, size, production of milk and the type of milk produced and the severity of the symptoms depending on the severity of the infection and its type and stage, and notes on the drowning in the case of infection that it is painful and painful and swollen, and in severe cases followed by decay and fibrous tissue when Inflammation is chronic. In addition, in some acute cases, general changes occur in the body of the animal, including high fever, loss of appetite, and even sudden death when a severe toxicity occurs.

In the examination of milk noticeable changes in its specifications such as color change, odor, textures and density, it may become sticky texture and showing white granules and can be quick reference to some of the following cases:

-           If the milk appears reddish white, this indicates the presence of red corpuscles, natural or broken, and this occurs when the infection Staphylococcus aurous.

-           If the milk appears in a watery yellow color, this may be evidenced by the infection of bacteria similar to coliforms.

emerging disease is  that  diseases which appear anew    as example;  zika, and  Avian diseases but 

the reemerging disease is the disease  which we know and control  it in the past and now this disease is appear back as  T.B .

Emerging are new communicable diseases which are coming where as re emerging are the ones which we almost eliminated in the past.
