在巴西进行了一项田间研究，以评价用两种疫苗单次接种猪预防猪肺炎支原体肺部病变的有效性。第一个（T1）处理组（174头猪）注射2 mL生理盐水; T2组（177头猪）注射2 mL阿托伐他汀A，T3组（174头猪）注射2 mL阿托伐他汀B。在试验日（DOT）0、35、66、97和125天，从选定的猪中采集血样和扁桃体拭子，用于抗体测定（间接ELISA）和PCR测定M的存在。下丘脑在DOT 126-129屠宰猪，并对肺部病变进行盲法评分。
A field study was conducted in Brazil to evaluate the efficacy of single vaccination of pigs with two bacterins to prevent Mycoplasma hyopneumoniae lung lesions. The first (T1) treatment group (174 pigs) was injected with 2 mL of saline solution; group T2 (177 pigs) with 2 mL of bacterin A, and group T3 (174 pigs) with 2 mL of bacterin B. On days-on-test (DOT) 0, 35, 66, 97 and 125, blood samples and tonsil swabs were collected from selected pigs for antibody determination (indirect ELISA) and PCR assay for the presence of M. hyopneumoniae. Pigs were slaughtered on DOT 126-129 and lung lesions were scored blindly.Bacterin A vaccinated pigs had significantly (P
