Abstract
Campylobacter jejuni or Campylobacter coli infection can lead to post-infectious irritable bowel syndrome in humans and may produce a similar syndrome in rhesus macaques (Macaca mulatta). We report the complete genomes of 8 C. jejuni isolates and 103 C. coli isolates obtained from rhesus macaques with and without intestinal disease.

Abstract
Post-harvest Salmonella mitigation techniques are insufficient at addressing Salmonella harbored in cattle lymph nodes, necessitating the exploration of pre-harvest alternatives that reduce Salmonella prior to dissemination to the lymph nodes. A 2 × 2, unbalanced experiment was conducted to determine the effectiveness of pre-harvest treatments applied to the pen surface for Salmonella mitigation in cattle. Treatments included manure slurry intended to mimic pen run-off water (n = 4 pens), a bacteriophage cocktail (n = 4), a combination of both treatments (n = 5), and a control group (n = 5) that received no treatment. Environment samples from 18 feedlot pens and fecal grabs, hide swabs, and subiliac lymph nodes from 178 cattle were collected and selectively enriched for Salmonella, and Salmonella isolates were sequenced. The combination treatment was most effective at reducing Salmonella, and the prevalence was significantly lower compared with the control group for rump swabs on Days 14 and 21. The treatment impact on Salmonella in the lymph nodes could not be determined due to low prevalence. The reduction on cattle hides suggests that bacteriophage or water treatments applied to the feedlot pen surface may reduce Salmonella populations in cattle during the pre-harvest period, resulting in reduced contamination during slaughter and processing.

Abstract
Short-chain fatty acids (SCFAs) are by-products from microbial metabolism of fibers with anti-inflammatory effects. SCFAs may mitigate inflammatory conditions such as obesity through modulation of histone acetylation. Lipid metabolism and inflammation play critical roles during pregnancy. However, few studies have examined maternal SCFAs in relation to pregnancy outcomes. This pilot study examined plasma SCFAs in spontaneous preterm birth. This study used stored plasma from an existing cohort to measure seven (proponic acid, methanoic acid, butanoic acid, isovaleric acid, pentanoic acid, methylpropylbutanoic and methylbutanoic acids) SCFAs in 20 women with spontaneous preterm delivery (< 37 weeks gestation) and 30 women with a healthy term delivery (≥ 37 weeks gestation). All women had singleton pregnancies and provided serum at the time of admission to labor and delivery. SCFAs were measured by purge and trap gas chromatography/mass spectrometry. SCFAs were log transformed. Logistic regression with penalized likelihood approach examined associations between SCFAs and preterm birth, adjusting for age, BMI, and race. We also explored if SCFAs had a linear association with pre-pregnancy BMI. Propionic acid had a negative association with preterm birth [odds ratioadj: 0.56, 95% confidence interval 0.41-0.86). There was a negative association between propionic acid and BMI after adjustments (β = -0.14, p = 0.0011). No other associations were found. Lower levels of propionic acid were associated with preterm birth and correlated with higher BMI. Larger studies should explore if circulatory SCFAs protect against inflammatory pathways during pregnancy and are associated with adverse outcomes when measured earlier in pregnancy.
