Fowl Adenovirus Serotype E (FADV - E)

Overview of Fowl Adenovirus Serotype E (FADV-E)

Fowl Adenovirus Serotype E, is a kind of Fowl Adenovirus Serotype, belongs to the avian Adenovirus. Avian adenovirus is a kind of double stranded DNA viruses without posterior capsule, epithelial cells of respiratory and digestive tract in poultry replication, form contains the body. Avian adenovirus has a greater resistance to the environment, can through the way such as manure, nasal tracheal secretion, semen eduction body outside, and contaminated feed, water and environment, cause the spread.

Effect of avian adenovirus type E

Avian adenovirus E can cause a variety of diseases of poultry, including pericardial effusion (HHS), inclusion body hepatitis - hepatitis syndrome (IBH) and muscular stomach erosion (GE). These diseases not only pose a threat to the health of poultry, and poultry breeding industry brought huge economic losses. The popularity of fowl adenovirus type E and prevention and control is very important to ensure the steady development of poultry industry.

The prevention and control of avian adenovirus type E

In order to effectively control avian adenovirus type E, can take the following measures:

1. Biosecurity measures: no imported from the epidemic area field young seedlings, poultry disease should be separated from flocks of health quarantine, dead birds disposal should be taken. On a regular basis for all kinds of equipment, personnel, water disinfection, prevent the spread of level.
2. Vaccination: good immunogenicity of fowl adenovirus, vaccination can be effective in preventing the disease. Chicken open prenatal January and half a month a shot inactivated vaccines, chicks in inactivated vaccine injection before and after 7 days of age.
3. Breeding management: pay attention to the ventilation poultry farm, add vitamin a in drinking water, enhance immunity. When combined the diet nutrition balance, reduce stress factors.
4. Disease surveillance: on a regular basis for health monitoring of poultry, once found the outbreak, isolation and treatment measures in time, to prevent the spread of the disease.

Through the above measures, can effectively control the spread of avian adenovirus type E, reduce the incidence of disease, the sustainable development of guarantee the health of poultry and livestock farming.

The main object of infection of fowl adenovirus type E

Avian adenovirus E (FAdV - E) is a kind of fowl adenovirus serotype, it belongs to the avian adenovirus. According to the molecular structure characteristics of the virus, FAdVs can be divided into five kinds, respectively is A, B, C, D and E. According to the serum cross neutralization reaction, can be divided into 12 serotype (FAdVs 1 ~ 7, 8 a, 8 b, 9 ~ 11). Avian adenovirus type E (FAdV - E) is one of the serum type, but in the existing literature, specific information about FAdV - E is less, so can't provide detailed object information.

In general, avian adenovirus can infect a variety of birds, including chicken, Turkey, duck, goose, etc. Different serotype avian adenovirus might be in different kinds of birds have different tendencies and pathogenic infection. FAdV - 4, for example, the main cause of chicken syndrome (HPS), pericardial effusion and FAdV - 2, 8 a, 8 b, and 11 are associated with infectious bursal disease (IBH). In addition, FAdV - type 1 is associated with muscle disease of gastric debaucjed, but and FAdV FAdV - 4-8 fatality rate of 100% of chicken embryos.

Because of the lack of specific research data about FAdV - E, the main infection object is currently not accurate. If you need to know more information about avian adenovirus type E, suggested that refer to the latest scientific research or consulting relevant experts in the field of.

The spread of avian adenovirus E way

Avian Adenovirus E (Avian Adenovirus Serotype E, AAVE) is a kind of virus can infect birds, the main route of transmission include:

1. Adenovirus type E can be directly contact: birds by direct contact with infected birds or their secretions, waste to spread. Between this way including birds peck at each other, fighting, or contact with the surface of the polluted environment.
2. Vertical transmission, the virus can also through the way of vertical transmission, that is, from infected mother bird to chicks. This usually occurs in the process of incubation, the virus through the shell surface or egg yolk is passed to the embryo.
3. Air: although common, as well as direct contact with poultry adenovirus type E may also be spread by the particles in the air, especially in the high density cultivation environment.

In order to prevent the spread of avian adenovirus type E, take the following measures:

• Good biosecurity measures, limiting non-essential personnel and animals into the farms.
• Regular cleaning and disinfection facilities farms, especially those areas of direct contact with birds.
• Isolation of the newly introduced birds, watch for a period of time to ensure that they are not infected with the virus.
• For infected birds, should be timely isolation and appropriate treatment measures.

Please note that the above information is based on the general avian adenovirus spread knowledge, particular case may be different, advice for more detailed guidance veterinary or professional institutions.

The prevention of avian adenovirus type E

Avian adenovirus type E (FAdV - E) is a kind of important pathogens of poultry, can cause many diseases, including pericardial effusion - hepatitis syndrome. In order to effectively prevent avian adenovirus E infection, here are some key precautions:

1. Vaccination: vaccine is to prevent avian disease one of the effective, economic and convenient way. Avian adenovirus type E, can use a specific vaccine immunization. These usually includes inactivated vaccine and weak vaccine, by dripping nose, eye, drinking water, injection or aerosol immunization vaccination. Vaccination, the vaccine should be paid attention to the preservation of the temperature and the period of validity, and ensure the effectiveness of the vaccine.
2. Biosecurity measures: strengthen farms of biological safety management, to prevent the introduction and spread of the virus. This includes not young seedlings imported from the epidemic area, the incidence of chickens in isolation, as well as to the dead chickens for disposal. Sheds at the same time, should be conducted on a regular basis, equipment and water disinfection, to prevent the horizontal transmission of the virus.
3. Environmental management: keep appropriate breeding environment, avoid overcrowding and poor living conditions, these are may increase the risk of infection of fowl adenovirus type E. In addition, attention should be paid to the influence of climate change on the crowd, timely adjust management measures, to relieve the negative effects of environmental stress on chickens.
4. Provide a balanced feed nutrient management: to ensure chickens get enough nutrition, to enhance their immunity. Especially during the cold weather or other virus disease epidemic, should be appropriate to increase the intake of vitamins and minerals, help chickens against disease.

Through the integrated use of the above measures can effectively prevent avian adenovirus E type of infection, to ensure the health of poultry and production performance.
