ND-EDS-76 inactivated oil emulsion vaccine treatment failure cases analysis of the immune


76 chickens have been a virulent infection in EDs, which HI titers of 1 | 2 ~ 1i83. EDS a 76 with a standard AGP antigen, the pathogenesis of group A on day 7, B and c group group on day 15 of the 30 sera drawn orange. AGP test for A, B group EDS a 76 positive rates were 15 ~ 20, c group were all negative. Summary of Incidence of chickens. The clinical diagnosis, laboratory diagnosis and pathology analysis, A,[link widoczny dla zalogowanych], B chickens are still identified as the EDS a 76, c group is not infected. Fourth, comprehensive prevention and control measures 1. Urgent vaccination of chickens against disease EDls an oil seedlings. 7O or more higher than egg production, 0.5 ml per chicken vaccine intramuscularly. Less than 7O% of egg production. Intramuscular injection of one milliliter per chicken. Week after inoculation the phenomenon of control of the egg drop, egg production rebounded after two weeks, three weeks after the B group by a 60.5% rise to 75, A group of 73 recovered from the 5O, provincial judge to obtain a good effect. 2. Overall implementation of a comprehensive examination, and do three times a week with chicken Terrace environmental and drinking water disinfection. Control the level of this disease work Case swelling f_ trial B (, /, Shandong poultry 1 capsule in 1994, will flood the solvent treatment efficacy of chicken bursal disease .. Fort Room mandarin duck hanging chalk (Qilu Pharmaceutical veterinary Factory 250100) chicken chicken bursal disease is an acute, highly contagious disease. in recent years has been plagued by a large number of households raise chickens, to the poultry industry has brought significant economic losses. At present, the treatment of high serum-free chicken bursal disease, but its in chickens late effects are not ideal, but easy to catch chickens injected with the stress caused by the chicken. So to find an efficient and easy to use drugs a top priority. Qilu Pharmaceutical veterinary medicine plant with the scientific research units after years of research, and finally developed a highly effective treatment of IBD drugs - capsule will flood the solvent, the clinical trial, the effect is good. now test reported as follows: First, materials and methods: 1 . bursal disease virus strains: IBDVBCS/S5F. 2.30 days without bursal disease (fBD) vaccine in chickens: 250 G, Lu pharmaceutical plant for experimental animals). 3. Capsule will flood the solvent: Qilu Pharmaceutical veterinary medicine factory production, production batch number: 931015. Second, the method: test by 30 days without IBD vaccine in healthy chickens were randomly divided into five groups. Q 5o chickens each set of the control group (no drug administration does not attack), positive control group (no drug administration Mei), drug treatment group (after onset of attack drug administration): points lower. sg marrow (A), in (B), high (c) the three dose groups. In addition to the negative control group, the other eye drops in each group were inoculated with bursal disease virus of chicken O. 95ml / only (equivalent to l90ELD.). Attack 72 hours after drug administration of drinking water for three days, returned to normal when tested to the end of the chicken. Chickens were weighed before and after each test record. Third, the test results; 1. After the chicken virus attack incidence; (r) 72 hours after virus attack, attack disease virus in chickens group, showing the spirit wilt Mi,[link widoczny dla zalogowanych], feathers loose chaos, the mouth into the feathers. Department head pre-tremor, leisure eyelid closure, squatting like necking, body resentment increased, anorexia,[link widoczny dla zalogowanych], thin row of white water stool. From each of five drug groups attack autopsy found that: the chicken leg or breast muscle or strip spotty bleeding, swollen liver and kidney-shaped, glandular stomach, muscular stomach at the junction of bleeding spots; bursal serosal congestion, glue jelly-like edema, the volume was significantly enlarged, sac mucosal fold edema, bleeding spots. Incidence rate of 10O (2) negative control group had no symptoms, all the normal 2. After three days of continuous administration, the status of each eye the chicken survived the positive control group cut loose chicken feathers, chaos, lack of luster, thin row of white or yellow droppings,[link widoczny dla zalogowanych], do not like to feed. A dose treatment group survived chicken feathers loose chaos, slightly shiny, thin yellow discharge manure, feed improved; B, c chicken spirit of the treatment groups survived better than the smooth feathers, appears shiny. Normal intake, fecal dry. Vertical transmission. 3. Adhere to the EDs of 76 antibodies for a monitor, to grasp the immune status of chickens to study the feasibility of the current immunization program and vaccine potency to determine their immune effects. 4, anti-disease vaccine in chickens fed an appropriate growth hormone drugs and multi-dimensional prevention of secondary infection, increased disease resistance. V. Analysis of the pathogens 1. EDS occurs in immune chickens is one of 76 initial cases in the city. C from the sampling of a group of 78 layers of serum antibody detection of EDS situation, and do not tidy the lowest efficiency, 75 days old may be infected with bursal disease in chickens and destruction of immune function related to reduced immunity. 2, A, B are two groups of 76 layers of a virulent EDS vulnerability is strong, while the C group of white shell layer has a certain anti-infectious. 3EDs a 76HI antibody levels and immune system has a certain correlation,[link widoczny dla zalogowanych], which measure the EDs can become the sole criterion of a 76 resistance, remains to be verified in future trials. . * 2�� *
