“…Treponemes were not found via histopathology, including in the Wharthin-Starry stain. The absence of these potential causes is in contrast with the findings of some other studies (Warnick et al, 2002;Stamm et al, 2009;Sobhy et al, 2019). Our findings are in line with the study of Sorge et al (2019), in which also no involvement of treponemes or mites could be demonstrated.…”

“…Warnick et al (2002) studied the possible involvement of Sarcoptes mites but concluded that parasitic control did not eliminate UCD lesions. Other studies suggest the involvement of treponemes, based on a positive correlation between the prevalence of UCD and digital dermatitis on farm level or detection of treponemes in udder skin or foremilk (Stamm et al, 2009;Evans et al, 2010;Sobhy et al, 2019). However, this was not supported by a recent study by Sorge et al (2019), in which the authors concluded that it seemed unlikely that spirochetes play a major role in the development of UCD.…”

Udder cleft dermatitis (UCD) or udder sores is a skin lesion, characteristically located around the anterior junction between the udder and abdomen of dairy cows. It is a worldwide problem in dairy herds with a large effect on animal welfare. The etiology and possible infectious origins of UCD are largely unknown; however, specific bacterial or parasitic causes are suggested in the literature. Therefore the aim of this study was to investigate the possible bacteriological, mycological, or parasitic involvement in clinically scored UCD lesions. Bacteriological culture was performed on subcutaneous tissue samples taken postmortem at a depth of 5 to 10 mm of 87 mild or severe UCD lesions or from the same place in healthy cows. Fungal culture was performed on a subset of 22 subcutaneous tissue samples of severe UCD postmortem. To investigate the superficial flora, swabs were taken from normal skin or skin lesions of 15 live animals equally divided over 3 groups: healthy skin or mild and severe UCD lesions. Histopathology, to describe and classify the lesions and to assess the presence of mites, fungi, or bacteria, was performed on 128 tissue samples, taken separately. In severe UCD lesions, Trueperella pyogenes and Bacteroides pyogenes were more frequently present in deep tissue layers and in superficial layers, compared with the same layers in mild UCD lesions or healthy skin. Culturing and histopathology indicated no sign of involvement of treponemes, Staphylococcus aureus, Escherichia coli, fungi, or mites in the UCD lesions. Histopathological examination showed that the majority of the lesions were characterized by chronic aspecific inflammation. Severe UCD lesions more frequently showed chronic active inflammation on histopathology, compared with mild UCD lesions. Due to the cross-sectional character of this study, it is difficult to differentiate cause and effect; however, future preventive and curative measures against UCD should take into account the chronic and anaerobic nature of this illness.

Cattle farming is an ancient practice, with roots in the early Neolithic era that has retained a major status in the food industry, with global beef market revenue amounting to $385.7B (as of 2018). Hence, cattle maintenance is essential for catering to the nutritional requirements of modern civilization. This extensive review aims to provide a holistic overview of the cattle microbiome, analyzing the native microbial composition within the respiratory tract, gastrointestinal tract, reproductive tract, and skin of cattle. The dysbiosis associated with various diseases such as bovine respiratory disease, bovine digital dermatitis, mastitis, Johne’s disease, uterine diseases (metritis and endometritis), and metabolic disorders (ruminal acidosis and ketosis) have been discussed. Moreover, various non-antibiotic microbial therapies including phage therapy, prebiotics, and probiotics have been examined as potential means to reduce disease-associated dysbiosis. In general, this review highlights the importance of the microbiome in the maintenance of health in cattle and its potential in alleviating bovine diseases, with an aim to enhance cattle health and production.

: Cattle farming is an ancient practice, with roots in the early Neolithic era that has retained its status in the food industry today, with global beef market revenue amounting to $385.7B, as of 2018. Hence, cattle maintenance is naturally essential to cater to nutritional requirements of modern civilization. This extensive review aims to provide a holistic overview of cattle microbiome, analysing the native microbial composition within respiratory tract, gastrointestinal tract, reproductive tract, and skin. The dysbiosis associated with various diseases such as bovine respiratory disease, bovine digital dermatitis, mastitis, Johne's disease, uterine diseases (metritis and endometritis) and metabolic disorders (ruminal acidosis and ketosis) has been discussed. Moreover, various non-antibiotic microbial therapies including phage therapy, prebiotics and probiotics have been examined as potential means to reduce disease-associated dysbiosis. In general, this review highlights the importance of the microbiome in maintenance of health in cattle and its potential in alleviating bovine diseases, with an aim to enhance cattle health and production.
