Abstract:
BACKGROUND:Two hemoplasma species, Mycoplasma suis and M. parvum, previously known as Eperythrozoon suis and E. parvum, respectively, have been identified in pigs. Swine hemoplasmosis is a global problem, and M. suis infection results in economic losses to pig producers worldwide. This study investigated the frequency and distribution of hemotropic mycoplasmas in pig farms of Korea. As hemoplasmas can be transmitted by ticks, we also analyzed the presence of the tick-borne pathogens Anaplasma spp. and Borrelia spp. METHODS:We screened 1867 samples from 464 pig farms located in four regions of Korea over the period from 2014 to 2018. PCR-positive samples were further analyzed by nucleotide sequencing and phylogenetic analysis of pathogen-specific markers for species identification. RESULTS:Of the 1867 pigs evaluated in the study, three (0.2%), 51 (2.7%), and one (0.1%) were found to be infected with M. suis, M. parvum, and the novel hemotropic M. haemosuis, respectively; Anaplasma spp. and Borrelia spp. were not detected. The 16S rRNA sequences of M. suis, M. parvum, and the novel hemotropic M. haemosuis were highly similar (99.3-100%, 99.6-100%, and 99.6-100%, respectively) to those of Mycoplasma spp. isolated from other countries. To the best of our knowledge, this is the first nationwide, large-scale study of the molecular detection of Mycoplasma spp. in domestic pigs in Korea. CONCLUSIONS:Our results indicate that Mycoplasma infections are widespread in Korean domestic pigs, and that continuous monitoring and control strategies are required to prevent the spread of hemoplasmas, which, in addition to causing economic losses in the pig industry, pose a potential threat to public health. As transmission routes of hemoplasmas remain unelucidated, additional epidemiological studies are recommended to identify reservoirs and vectors of Mycoplasma spp. in Korea.
