The majority of species previously categorized as Bacteroides have been reassigned into new genera. Bacteroides levii (Holdeman, Cato, and Mooretaxonomic)'s status has remained uncertain. This species shares a high degree of similarity with members of the genus Porphyromonas based on biochemical, chemical, and comparative 16s rRNA sequence analysis. As a result, Bacteroides levii (Holdeman, Cato, and Moore) was reclassified as comb. now under the genus Porphyromonas.

Article Synopsis
  • The study investigates the sources and reservoirs of bacteria related to digital dermatitis (DD) in dairy cattle, focusing on various body sites and environmental samples from affected and unaffected herds.
  • Researchers collected skin swabs, saliva, urine, feces, and environmental samples to analyze the presence of specific bacterial species associated with DD using real-time quantitative PCR.
  • Findings indicate that DD-associated Treponema bacteria are exclusively present in DD-affected herds and lesions, while non-Treponema species exist in both types of herds, suggesting that saliva and compromised skin may play a crucial role in bacterial transmission instead of feces or urine.

The objective of this study was to characterize the species composition and functional potential of the vaginal and uterine microbiota at 1 wk postpartum in dairy cows diagnosed with or without purulent vaginal discharge (PVD) at 3 wk postpartum. The hypothesis was that differences in the vaginal and uterine microbiota between cows diagnosed with (PVD+) or without (PVD-) PVD were dependent on parity and breed. Cytobrush samples of the vagina and uterus were collected at 1 wk postpartum from 36 Holstein-Friesian (7 primiparous and 29 multiparous) and 29 Jersey (10 primiparous and 19 multiparous) cows.

Dynamics and Diversity of Intrauterine Anaerobic Microbiota in Dairy Cows with Clinical and Subclinical Endometritis.

Clinical Unit for Herd Health Management in Ruminants, University Clinic for Ruminants, Department for Farm Animals and Veterinary Public Health, University of Veterinary Medicine Vienna, 1210 Vienna, Austria.

The aim of the study was to characterize the dynamics of anaerobic cultivable postpartum microbiota in the uterus of dairy cows. In total, 122 dairy cows were enrolled and sampled on day 0 (day of calving) and on days 3, 9, 15, 21, and 28 postpartum (pp). Samples were cultivated anaerobically and analyzed by MALDI-TOF MS.

Digital Dermatitis (DD) is a polymicrobial disease characterized by ulcerative lesions on the heel bulb of cattle and for which, despite being reported almost 50 years ago, information on the causative agent is still lacking. Tissue biopsies are regularly collected to identify bacterial presence-absence and their relative abundance in the microbiome, with sufficient evidence for the high abundance of species of spp. and other anaerobes in lesions.
