Quarantine and identification of anthrax pigs

The same result. As a victim of the lymph nodes showed acute hemorrhagic, necrotizing inflammation, it began to congestion, swelling, bleeding and edema into features; course the more anxious the more extensive the bleeding, lymph node section the more evenly reddish brown; again Because of its intense proliferation, the proliferation of lymphoid follicles showed swollen lymph nodes. Rough dull, granular cut surface: when the development of severe hemorrhagic inflammation in the lymph nodes are dark red necrotic lesions. In chronic cases,[link widoczny dla zalogowanych], due to the decomposition of red blood cells. Necrotic lesions were brown. In the lymph nodes around. Because of the large population of Bacillus anthracis produce toxins, enzymes, and capsular material, so that the local organization was severely damaged,[link widoczny dla zalogowanych], and to the basement membrane of connective tissue disintegration and liquefaction: the same time as the accumulation of various inflammatory exudate. Local inflammatory lesions increased osmotic pressure and vascular permeability. Constitutes a serious local tissue hemorrhage, edema. As well as rubber-like infiltration. At the same time, can be found in the edema fluid and a large number of neutrophils from Bacillus anthracis cells. Anthrax quarantine in the head, the tonsil test can not be ignored, because first of all damage to the amygdala of Bacillus anthracis, the lesion was depression in the middle of necrotic lesions, together with pseudomembrane, the membrane was under the Ministry of brown necrotic gray, dull and dry. The pig's natural defenses against anthrax, leaving the natural incubation period of anthrax infection is often much longer than other animals. Even up to several months. So the dude in the post-mortem found that the Department of General Ante-mortem no obvious symptoms of anthrax, and pathological changes are also in different stages of disease, the lesions are not typical, but also in lymph node size, color, hardness and plastic are also different kind of invasion. So in the local pig for diagnosis of anthrax. Should be comprehensive and systematic analysis of the pathological changes characteristic can not be causing too much emphasis on a false detection, undetected. 1.2 The failure of this type of anthrax blood on the rare anthrax in pigs. General performance of pigs suffering from: Dying of the nose and mouth,[link widoczny dla zalogowanych], anus and other natural larvae L bleeding, blood, dark red, viscous, tar-like, freezing insufficiency in 2 swine feed samples of anthrax defeat measures on the blood pigs with acute lesions of lymph nodes from anthrax sampling sites or lesions in the spleen and marrow smear staining; of porcine partial anthrax, from depression necrosis in lymph nodes at the smear, staining, microscopy, or from inflammatory infiltration at the sample. Differential diagnosis and testing 3,[link widoczny dla zalogowanych],1 3 sunstroke and heatstroke with the identification of pigs in the hot season. Often due to sunstroke and heatstroke caused death. Corruption bodies such patients quickly and fermented pig, performed significantly expanded; the same time, CHINASWINEINDUSTRYI41 Lunsha cH control evasion in 2007 by the state ��Canal expansion because of corruption. The risk of anal ectropion pig congestion, nose and mouth out of bloody fluid. However, this thin pale red liquid. So. Do not mistake in the actual production in order to do this is anthrax. To avoid causing misdiagnosis. 3.2 Identification with piroplasmosis and other blood group defeated enlarged spleen of anthrax should be distinguished from the following two wards. First, piroplasmosis. This disease will be enlarged spleen of pigs several times; but the spleen and marrow red brownish red or yellow. And piroplasmosis thin the blood, the body has obvious jaundice. The other is lymphatic leukemia. Sick pig spleen touch of hard,[link widoczny dla zalogowanych], cut a crisp sense of the medulla. Carcass and visceral lymph nodes at the same time hard and brittle, pale, such as fish-like. 3,3 and test the difference between Bacillus cereus Bacillus anthracis are capsular 3.3.1. The colony was hair-like. Were tested either center or edge of the hair-like. The wax bacteria colonies was only the Ministry of curls at the edges like (such as dendritic or ivory-like protruding from the colony and not to turn back): elongated chain staining of Bacillus anthracis, the bacteria end cut straight. The wax bacillus stain was single or short chain, bacteria side obtuse. 3.3,2 in ordinary broth culture. Bacillus anthracis was flocculent precipitate, floating liquid cool and bright: the wax bacillus medium turbidity. 3,3,3 in the blood agar plate culture 18 ~ 24T, Bacillus anthracis is not hemolytic. The wax is hemolytic bacteria. 3_3.4 Hl�� with each unit containing 10% penicillin agar, Bacillus anthracis can not grow, the growth of the Prince as usual bacilli. In short, the anthrax in our meat quarantine quarantine an important role. So pay particular attention to the quarantine of this disease. Submandibular lymph nodes, especially the head. Not because of local non-anthrax anthrax or not the neglect of anthrax swine quarantine. Furthermore. Testing of suspected anthrax, caused by the shutdown and quarantine blockade. Meat processing losses are quite large, so they requested us to promptly and accurately make the diagnosis of this disease. So as to rapidly laboratory confirmed. Lay a good foundation. To prevent false detection, and reduce the occurrence of the phenomenon of missed waste of resources. �� clinical application confirmed. Independently developed by China of highly pathogenic blue ear pig disease vaccine, but tests show that the retrospective effect, the subject of attack protection rate accounted for 88.2%.
