Microbial communities and inflammatory response in the endometrium differ between normal and metritic dairy cows at 5–10 days post-partum

Table 2 Prevalence and mean abundance (± SEM) of selected bacterial genera in healthy and metritic cows

Genus	Prevalence		Abundance		P value
Genus	Healthy (%)	Metritis (%)	Healthy (%)	Metritis (%)	P value
Bacteroides	42.1	27.3	4.3 ± 2.0	10.7 ± 4.4	0.121
Escherichia/Shigella^a	26.3	9.1	10.8 ± 6.2	0.5 ± 0.5	0.261
Fusobacterium	68.4	90.9	2.8 ± 1.2	12.4 ± 5.2	0.013
Porphyromonas	47.4	90.9	10.2 ± 4.9	29.8 ± 8.0	0.011
Trueperella	47.4	72.7	0.2 ± 0.1	0.2 ± 0.1	0.288

Samples were collected by endometrial swabs at 5–10 days post-partum and used for 16S-rDNA pyrosequencing analysis.
^aThe Escherichia/Shigella genera have a high similarity in the 16S-rRNA gene and thus both appear as the same OTUs according to the protocols used in this study.
