　　GLOBAL - Two organisms that can cause serious respiratory diseases in pigs are the bacteria Mycoplasma hyopneumoniae and Actinobacillus pleuropneumonia. Vaccination is used to help farmers prevent infections but due to complexities, vaccination procedures may need to be reviewed or improved.M. hyopneumoniae is in fact endemic in most pig herds around the world. The organism is often transmitted through the movement of infected pigs or by windborne infection.As it is usually a subclinical disease, it can often go unnoticed until it is too late. The programme gives pig farmers and veterinarians the ability to assess the quality of the respiratory disease management currently in place at the farm and to guide the implementation of actions to reach better respiratory health.

　　豬體內(nèi)有兩個(gè)能引起嚴(yán)重呼吸道疾病的病菌，分辭是豬肺炎支原體(Mycoplasma)細(xì)菌和胸膜肺炎放線桿菌(Actinobacillus)。接種疫苗幫助豬農(nóng)防止感染，但是過程重雜，疫苗接種程序也許需要評(píng)估和改進(jìn)。豬肺炎支原體實(shí)際上在全世界大多數(shù)豬群流行。病菌時(shí)常通過感染豬的相互接觸和風(fēng)傳播。這是一種亞臨床疾病，時(shí)常癥狀不顯然，發(fā)病后為時(shí)已晚。推出的新準(zhǔn)備讓豬農(nóng)和獸醫(yī)適時(shí)地評(píng)估當(dāng)前農(nóng)場(chǎng)呼吸道疾病管理項(xiàng)目質(zhì)量，通過實(shí)際指導(dǎo)達(dá)到更好的呼吸道健康標(biāo)準(zhǔn)。
