| Bacterial sexually transmitted diseases on the pig industry more and more serious harm than the virus disease, bacterial disease and the relationship of feeding and management, environmental conditions and other factors more closely, and prone to secondary or mixed infection.The bacterial disease vaccine protective effect is generally poor, people tend not picked a suitable disinfectant to disinfect, but to place undue reliance on antibiotics and other drugs for treatment, resulting in increased resistance strains, and thus the formation of a vicious cycle.By comparing several disinfectants role in the killing of several common pathogens, clinically appropriate disinfectants provide a theoretical basis.Different dilutions of four disinfectants, different time, different temperatures vitro kill Salmonella choleraesuis, Staphylococcus aureus, porcine Haemophilus swine Pasteurella, Streptococcus suis, Pseudomonas aeruginosa, six kinds of common pathogensmicrobial effect, comparative experimental results of viable test, to find the disinfectants common indigenous microorganisms optimal dilution, temperature and time.The results showed that:1, is cleared in at4℃,15℃, under the conditions of30℃, respectively, the role of5min,15min,30min, dilution factor of1:400to1:1500range,100%kill rate of Salmonella choleraesuis;dilution factor within the range of1:400to1:1000, the kill rate of100%of Staphylococcus aureus; dilution of1:400to1:800range killing rate of porcine Haemophilus100%; dilution of1:400to1:1500range, kill swine Pasteurella rate of100%; in dilution of1:400to1:800range, kill Streptococcus suisoff rate of100%; dilution ratio is within the range of1:400to1:1000, Pseudomonas aeruginosa kill rate of100%.2, the iodine is attached to the dilution factor of1:600to1:1500range the Salmonella choleraesuis kill rate of100%Dilution of1:600to1:1500range, the kill rate of100%of Staphylococcus aureus; dilution factor within the range of1:600to1:1000, the kill rate of porcine Haemophilus100%; dilution of1:600to1:1500range of swine Pasteurella the kill rate of100%; in dilution of1:600to1:1500range of Streptococcus suis100%kill rate; dilution of1:600to1:1500range,100%kill rate against Pseudomonas aeruginosa.3, is the net dilution factor of the Salmonella choleraesuis kill rate of100%within the range of1:800to1:2000; in dilution of1:800to1:1500range, the killing of Staphylococcus aureusrate of100%; dilution of1:800to1:1500range up to100%; pig killing rate of Haemophilus in dilution of1:800to1:2000range of pig PakistanBordetella kill rate of100%; dilution of1:800to1:1500range Streptococcus suis kill rate of100%; dilution factor of1:800to1:1500range100%kill rate against Pseudomonas aeruginosa.4months benzyl top three chloride solution in the dilution factor of1:400to1:1200range,100%kill rate of Salmonella choleraesuis; dilution factor of1:400to1:1200range of goldaureus kill rate of100%; dilution of1:400to1:1200range pig Vice Haemophilus kill rate of100%; dilution factor is1:400to1:1200rangewithin swine Pasteurella kill rate of100%; dilution of1:400to1:1200range100%kill rate for Streptococcus suis; dilution factor of1:400to1:1200range, Pseudomonas aeruginosa kill rate of100%.The results show that:the disinfectant selected in this experiment can be a good kill six common pathogens, but the four kinds of the disinfectant under the same conditions of the six common pathogen kill rate, it is clinically needed is selected according to the actual situationappropriate disinfectant. |
