Rabbits are more likely than other pets to be exposed all kinds of diseases. Protection from them begins by choosing a place for their maintenance. The place where it is supposed to contain rabbits should be with a dry litter, without stagnant water, as the retention of water in the form of puddles leads to the development of microorganisms that can cause diseases of animals. Purulent inflammation in rabbits is one of the most common pathological processes. Features and dynamics of the pathological process are determined by the specificity of the pathogenic factor and the reactive properties of the organism, as well as the external conditions of life. Often, the occurrence of abscesses is associated with a malocclusion (malocclusion syndrome). Once malocclusion is formed, the teeth stop stitching properly, and painful sharp regrowths that lead to trauma to the cheeks and tongue, as well as infection of the wound with microflora can form. One of the components of purulent exudate are microorganisms, which primarily lead to the development of a purulent process, they include staphylococci, pasteurella, Pseudomonas aeruginosa, Proteus. Purulent inflammation can be both an independent disease, and a secondary sign of the underlying disease. Rabbits have characteristics during inflammation, especially during proliferation. Healing of wounds proceeds according to the type of sequestration. It is important to understand how the inflammatory process affects the body. In this case, clinical blood indices were studied: erythrocyte sedimentation rate (ESR), hemoglobin, hematocritis, erythrocytes, leukocytes, granulocytes, lymphocytes, monocytes, platelets. As these indicators point to the course of the inflammatory process, the acuteness and reactivity of the organism.
