Introduction
Interdigital phlegmona (IP), present on almost all dairy herds, are diagnosed in young cows mainly (van Metre, 2017). Treatment with antibiotics (e.g. tetracyclin or penicillin) does result in rapid recovery normally. Since recent years GD Animal Health was approached weekly by practitioners and farmers about nonreacting (IP) problems whereby these cows had to be euthanized (sometimes > 10 cows/herd /year). The problem presented itself as an individual herd problem and not a sectorial problem (herd prevalence low (<1%), within herd prevalence 4-10%).
Materials and Methods
In the recent year 2018 a pilot investigation (survey, pathology and bacteriology) has been performed. Practitioners and farmers contacted GD-AH in case of problems and could send a cow for post-mortal investigation (macro- and microscopy and bacteriology). Eventually we had information of 7 dairy cows from 6 herds.
Results
Affected cows were both heifers and older dairy cows, from herds with and without pasturing and according the practitioners was the hygiene in these herds not worse in comparison to others. In 6 of the 7 cows the diagnosis of IP could be confirmed, one cow had a complicated sole ulcer with an osteomyelitis. Bacteriological investigation showed much variation with sometimes almost no bacteria and in other cases many different bacteria. A common pattern was not seen. Histological investigation based on a Wharthin-Starry stain (demonstrate spirochetes) showed that in the case of a non-responsive IP significantly more spirochetes sub-epidermal were present and also more often "ballooning degeneration/serious intracellular edema, which were less present in control claws (p<0.001).
Conclusions
The presence of spirochaetes in the superficial epithelium of the lesion of cows with TKO compared to non-lesional skin found. This may be a possible explanation for the failure of standard therapy.
