英文摘要 | The purpose of this study was to analyze the correlation of the rate of Mycoplasm a hyopneumoniae (M. hyo) in slaughter pigs with season, climate change and enzootic pneumonia (EP) lesions. We collected 530 slaughter pig lungs with suspected lesions from two slaughterhouses in different seasons and weather conditions from November 2014 to March 2017 in Changsha Hunan Province, China. The EP lesions of these lungs were quantified, and a PCR analysis was used to detect M. hyo in samples of bronchoalveolar lavage fluid (BALF). Twenty percent, 10%, and 9% of the lung specimens were scored 1-5, 6-10, and >= 11, respectively. Additionally, we found that 36% of all BALF samples tested positive for M. hyo. Among the lung specimens collected in winter, 41% scored 1 or more, and 53% tested positive for M. hyo. With respect to seasons, the lung specimens collected in summer showed the least number of EP lesions and the lowest positive testing rate for M. hyo. Of these specimens, 27% scored 1 or more, and 22% tested positive for M. hyo. Additionally, low temperature and fast temperature change (during 10 days before sampling) were associated with a higher rate of M. hyo detection in BALF. There was a positive correlation between the lung EP lesion score and the detection rate of M. hyo in the BALF of slaughter pigs. In conclusion, lung EP lesion scoring in slaughter pigs is of referential value to the evaluation of the dynamics of M. hyo infection in a swine population. It is essential to control the spread of M. hyo by careful management of swine populations, and the prevention and control of M. hyo in fattening pigs is of great significance to the eradication of the disease. |
