Abstract
Lesions of the distal extremities in lactating cows can be of both infectious and non-infectious etiology. Finger crumb ulcer or finger dermatitis or Mortellaro's disease and necrobacteriosis are infectious diseases. These diseases can occur if zoogynical rules of maintenance are not followed, if preventive measures are not taken (for example, untimely and poor manure harvesting, absence or improper use of preventive baths). Bacteriological material was taken from sick animals in the area of the finger crumb from five animals. The animal was fixed in a special orthopedic machine. Before taking the biopsy, local anesthesia was performed with a 2% solution of novocaine. The lesion was washed with tap water and dried with sterile wipes. The biopsy was performed at the border of healthy and damaged tissue with a tubular scalpel (punch) with a diameter of 5 mm. The samples were placed in tubes with liquid Ames transport medium. Under isothermal conditions, they were transported to the laboratory for 3 hours. Thus, when studying the culture of biopsies of bovine hoof crumb, a variety of microflora (environment, mucous membranes and skin, potentially pathogenic and purulent microflora, opportunistic fungi) and fungi that can potentially participate in the development and maintenance of inflammation of soft tissues, skin, its appendages and subcutaneous fat were isolated. It can be assumed that the main penetration of microorganisms into the focus of inflammation occurs from the external environment, during pathogenesis, the pathological process is complicated by purulent microflora, which further aggravates and complicates the course of the disease.
