Summary: | Particulate matter (PM) produced in pig houses may contain microbes which can
spread by airborne transmission, and PM and microbes in PM adversely affect
human and animal health. To investigate the microbiome in PM from pig houses,
nine PM samples were collected in summer 2020 inside and outside of pig houses
located in Jangseong-gun, Jeollanam-do Province, Korea, comprising three PM
samples from within a nursery pig house (I-NPH), three samples from within a
finishing pig house (I-FPH), and three samples from outside of the pig houses
(O-PH). Microbiomes were analyzed using 16S rRNA gene amplicon sequencing.
Firmicutes was the most dominant phylum and accounted for 64.8%–97.5% of
total sequences in all the samples, followed by Proteobacteria
(1.4%–21.8%) and Bacteroidetes (0.3%–13.7%). In total, 31 genera
were represented by > 0.3% of all sequences, and only
Lactobacillus, Turicibacter
, and
Aerococcus
differed significantly among the three PM sample
types. All three genera were more abundant in the I-FPH samples than in the O-PH
samples. Alpha diversity indices did not differ significantly among the three PM
types, and a principal coordinate analysis suggested that overall microbial
communities were similar across PM types. The concentration of PM did not
significantly differ among the three PM types, and no significant correlation of
PM concentration with the abundance of any potential pathogen was observed. The
present study demonstrates that microbial composition in PM inside and outside
of pig houses is similar, indicating that most microbe-containing PM inside pig
houses leaks to the outside from where it, along with microbe-containing PM on
the outside, may re-enter the pig houses. Our results may provide useful
insights regarding strategies to mitigate potential risk associated with pig
farming PM and pathogens in PM. |
