[Abstract]:Porcine respiratory disease syndrome (PRDC) is a disease caused by respiratory system damage caused by mixed infection of various pathogens, which seriously endangering the development of pig industry. Its incidence is in 35%-80%, the mortality rate is 5%-30% and above, the pathogenesis is complex and difficult to prevent. It is the main problem of pig industry. It causes the respiratory disease of pigs. The pathogeny of the disease is wide, and the onset of the disease is covered by various stages, including suckling piglets, pig breeding, fattening pigs and sows, which have a great danger to the prevention and control of large-scale pig farms. The bacterial pathogens of PRDC include Haemophilus accessory pigs, Actinobacillus contagialis, porcine Pasteurella pasteuricus, pneumonia chain. The viral pathogens include porcine reproductive and respiratory syndrome virus, porcine circovirus 2, porcine pseudorabies virus, swine fever virus and Mycoplasma pneumoniae are also an important pathogenic factor. A variety of pathogens often exist in a mixed infection mode, strengthen the damage to the body, increase the incidence of PRDC and mortality. The test selected four In Leshan, Ya'an, Xinjin, Xinjin, Tianquan, Baoxing, Nanchong, Chengdu, Meishan, Neijiang and Suining, 53 samples with typical symptoms of respiratory diseases were tested, and the bacterial pathogens were tested to understand the incidence of respiratory diseases and bacterial pathogens in parts of Sichuan province. The infection rate provides a theoretical basis for the formulation of a scientific and reasonable control plan. By statistical analysis of isolated strains, the infection rate of Streptococcus pneumoniae is the highest, reaching 69.81% (37/53), Pasteurella multocida, Haemophilus vice, contagious Actinobacillus pleuropneumoniae, lelestrus leeniformis, Pseudomonas aeruginosa, and Boss bacilli, in accordance with the infection rate The order of high to low was 54.72% (29/53), 47.17% (25/53), 20.75% (11/53), 16.98% (9/53), 13.21% (7/53), 9.43% (5/53). In the double infection cases of pathogenic bacteria, the mixed infection rate of Haemophilus accessory swine and Streptococcus pneumoniae was the highest, 32.07% (17/53), and the infection rate of mixed infection of Streptococcus pneumoniae and Pasteurella multocida reached 30.. 19% (16/53); the mixed infection rate of Pasteurella multocida and Haemophilus accessory swine was 22.64% (12/53); the mixed infection rate of Actinobacillus pleuropneumoniae and Streptococcus pneumoniae was 13.21% (7/53); the mixed infection rate of Streptococcus pneumoniae and Listeria was 11.32% (6/53), and the rate of mixed infection of Streptococcus pneumoniae and Pseudomonas aeruginosa was 9.43% (6/53). 5/53): the mixed infection rate of Pasteurella multocida and Pseudomonas aeruginosa was 7.55% (4/53); the mixed infection rate of Pasteurella multocida and Listeria was 7.55% (4/53); the mixed infection rate of Haemophilus accessory swine and Pseudomonas aeruginosa was 5.66% (3/53); the mixed infection rate of Haemophilus Haemophilus and Listeria was 5.66% (3/53); the infectious pleuropneumonia caving rod The mixed infection of the bacteria and the Haemophilus accessory swine was 5.66% (3/53); the infection rate of Boss and Pasteurella multiple (3/53) was 5.66% (3/53); the mixed infection rate of Streptococcus pneumoniae and bronchoalveolar septicus was 5.66% (3/53); the mixed infection rate of Pseudomonas aeruginosa and Listeria was 3.77% (2/53), and Haemophilus accessory Haemophilus and bronchial septicus The mixed infection rate of Boss bacilli was 1.89% (1/53), and the mixed infection rate of Boss and Listeria was 1.89% (1/53). In the three cases of pathogen infection, the mixed infection rate of Haemophilus accessory swine, Pasteurella multiple and Streptococcus pneumoniae was 11.32% (6/ 53), Haemophilus accessory swine, Streptococcus pneumoniae and Pseudomonas aeruginosa. The rate of mixed infection reached 5.66% (3/53), the infection rate of Streptococcus pneumoniae, Actinobacillus pleuropneumoniae and Pasteurella multocida reached 5.66 (3/53), and the mixed infection rate of Streptococcus pneumoniae, Pseudomonas aeruginosa and Pasteurella multocida reached 3.77% (2/53), and the mixed infection rate of Streptococcus pneumoniae, Streptococcus pneumoniae and Listeria strains reached 3.7. 7% (2/53); the mixed infection rate of Pasteurella Pasteurella, Streptococcus pneumoniae and Boss bacilli reached 3.77% (2/53); the mixed infection rate of Haemophilus accessory swine and Pasteurella and Pseudomonas aeruginosa reached 1.89% (1/53); the mixed infection rate of Haemophilus accessory swine, Boss and Listeria infection reached 1.89% (1/53); The infection rate of Actinobacillus pleuropneumoniae, Haemophilus accessory swine Haemophilus and Streptococcus pneumoniae reached 1.89% (1/53); the mixed infection rate of Listeria, Haemophilus accessory swine and Actinobacillus pleuropneumoniae was 1.89% (1/53), and the infection rate of contagious Actinobacillus pleuropneumoniae, Pasteurella multiple and Pseudomonas aeruginosa was 1.89% (1). /53); contagious Actinobacillus pleuropneumoniae, the mixed infection rate of Pasteurella multocida and Listeria was 1.89% (1/53); infectious Actinobacillus pleuropneumoniae, Streptococcus pneumoniae and Pseudomonas aeruginosa mixed infection rate reached 1.89% (1/53). In the four infectious diseases of pathogenic bacteria, Streptococcus pneumoniae, Haemophilus vice, Pseudomonas aeruginosa, and Pseudomonas aeruginosa The mixed infection rate of Pasteurella multocida reached 1.89% (1/53); the mixed infection rate of Listeria bacillus, Haemophilus porcine, Streptococcus pneumoniae and Pasteurella Mulus reached 1.89% (1/53); the mixed infection rate of Haemophilus Haemophilus, Streptococcus pneumoniae, Pseudomonas aeruginosa and Listeria was 1.89% (1/53), and Pasteurella multocida, Haemophilus vice and transmission of Bacillus subtilis The mixed infection rate of Actinobacillus pleuropneumoniae and Streptococcus pneumoniae reached 1.89% (1/53): Listeria, Pasteurella multocida, Pseudomonas aeruginosa and Streptococcus pneumoniae reached 1.89% (1/53).
