BVDV


Background:

Bovine Viral Diarrhea (mucosal disease) is an infectious disease caused by the Bovine Viral Diarrhea Virus (BVDV is a genus of fever Virus of the xanthovirus family). Cattle of various ages are susceptible to infection, with the highest susceptibility of young cattle.


Clinical significance:

Observation of clinical symptoms: the majority of cattle do not show clinical symptoms, cattle only a few light cases. Sometimes it causes sudden seizures in the entire herd. Acute cattle, diarrhea is a characteristic symptom, lasting 1-3 weeks. Fecal water, stench, lots of mucus and bubbles, rising body temperature。The diagnosis of this disease requires virus isolation, serum neutralization test and complement binding test, and serum neutralization test is commonly used in practice.




IBR


Background:

Infectious bovine rhinobronchitis (IBR), also known as "necrotizing rhinitis", "red nose disease", is a type I bovine herpes virus (bhv-1) caused by a contact respiratory infection of cattle. Clinical manifestations are diverse, mainly in the respiratory tract, accompanied by conjunctivitis, abortion, mastitis, and sometimes induced encephalitis in calves.


Clinical significance:

The typical case of this disease (upper respiratory tract inflammation) has characteristic symptoms such as nasal mucosa congestion, pustules, dyspnea, nasal discharge pus, etc., combined with epidemiology, a preliminary diagnosis can be made, but the diagnosis must rely on laboratory diagnosis, including virus isolation and identification and serological test. Virus neutralization test (VN) and various enzyme-linked immunosorbent assay (ELISA) are commonly used to detect BHV1 antibody in serum samples. In addition, there are AGAR diffusion test and indirect hemagglutination test. Since IBRV infection is usually latent, identifying serologically positive animals is a useful and ideal indicator for testing the infection status of animals. Antibody positive animals can be considered as carriers of the virus and potential intermittent detoxers, except calves with maternal antibody from colostrum and non-infected cattle immunized with inactivated vaccine.




Bovine Tuberculosis


Background:

Bovine Tuberculosis is a chronic infectious disease caused by Mycobacterium bovis, which is classified as a class ii animal epidemic disease in China. It is characterized by tuberculous nodular granuloma and caseous calcified necrotic lesions in tissues and organs.


Clinical significance:

monitoring of infections diseases




Hydatid


Background:

Hydatidosis is a zoonotic parasitic disease caused by the larvae of echinococcus. There are two kinds of echinococcosis and echinococcosis in China, which are caused by the larvae of echinococcus granulosus (hydatid) and the larvae of echinococcus multilocularis (echinococcosis) parasitizing human tissues and organs respectively. Cystic hydatidosis is widely distributed in countries and regions with developed animal husbandry.




Bacterium burgeri


Background introduction:

Brucella is a kind of gram negative short bacillus, cattle, sheep, pigs and other animals are most susceptible to infection, causing infectious abortion of female animals. Humans can become infected by contact with infected animals or by eating sick animals and their dairy products


Clinical significance:

1.Cultivation, acute blood collected, chronic phase to bone marrow, vaccination in bipolar liver immersion medium (cant half, half liquid) 37 ℃ 10% CO2 environment to cultivate and inspected once every 2 days, if no bacterial growth is oscillation medium, make the liquid soaked in ramp, bacterial growth, can be in accordance with the project for brinell coli are determined. No bacterial growth can be reported after 1 month of culture.


2.Serological examination, usually used for agglutination test, determines that the agglutination titer 1:50 is suspicious and 1:100 or more is positive. Titer increased by more than 4 times is more valuable for diagnosis.




Newcastle disease (ND)


Background:

Newcastle disease (ND) is an acute, hot, septic and highly contagious disease caused by Newcastle disease virus in poultry. It is characterized by high fever, dyspnea, dysentery, nervous disorder, mucous and serous hemorrhage. With high morbidity and mortality, it is a major infectious disease that endangers poultry industry.
