dc.description.abstract | Metritis affects up to 40% of dairy cows and it is usually treated with antibiotics. In
spite of their advantages, there is an increased concern about antibiotic resistance
leading to the research of alternative methods. The aim of this study was to evaluate
the effects of a combination of lactic acid bacteria (LAB) on the prevalence of metritis
and modulation of endometrial and neutrophil inflammatory markers in dairy cows. One
hundred and thirty-five cows were enrolled 3 week before calving and randomly assigned
to three treatments. Treatment groups were: (1) two intravaginal doses of LAB/wk during
3 week pre-calving (vaginal, n = 45); (2) an intra-uterine dose, once 1 d after calving
(uterine, n = 44); and (3) no intervention (CTRL, n = 45). Metritis was defined as body
temperature > 39.5◦C and purulent vaginal discharge (> 50% pus), and diagnosed
6 d after calving. Blood samples were taken at d −14, −10, −7, −4, +1, +3, +6,
and +14 relative to calving for non-esterified fatty acids (NEFA) analysis. At d −10,
+1, +3, and +6 neutrophils were isolated from blood for gene expression analysis
by RT-qPCR. Endometrium biopsies were taken from 30 cows, 15 from CTRL and 15
from the uterine group at d +1, +3, and +6 after calving for pro-inflammatory markers
analysis by NanoString®. Vaginal treatment reduced metritis prevalence (6/45) up to
58% compared with CTRL group (14/45), but there was no difference between the
uterine and CTRL group. Uterine and vaginal treatments reduced blood neutrophil gene
expression. Expression of pro-inflammatory markers in the endometrium did not differ
between uterine and CTRL cows. Metritic cows expressed more C-X-C motif chemokine
ligand 8 (CXCL8) and interleukin 1 beta (IL1B) at d 3 than healthy cows, whereas healthy
cows expressed more CXCL8 at d 1 relative to calving in the endometrium. This study
shows a promising potential of LAB probiotics as a preventive treatment against metritis
in dairy cows. | ca |
