Pathomorphological studies of caprine mastitic udder

Abstract

An in-depth study was conducted to find the pathomorphological alterations of udder tissue in four numbers of chronic caprine mastitis cases with six blocked teat. Does were screened for mastitis by presence of typical clinical signs of swelling, firmness or palpable nodules and/or partially /completely blocked teat, Somatic cell count (SCC) and Modified Californian Mastitis Test (MCMT). Haemto-biochemical observations showed decreased Hb, TEC and increased TLC along with increase in Total Protein (TP), Globulin, Na+ and Cl-. Representative tissue samples were collected after thorough curetting and processed for routine histopathology. The microscopic changes of udder parenchyma revealed mostly inflammatory changes with leucocytes infiltrations and replacement of fibrous connective tissue and/or atrophy of glandular tissue. Glandular lumens were filled with RBCS and some areas showed more fibrotic proliferation along with congestion and hemorrhages. This study will be helpful in refreshing the knowledge among the vets in the context of the paucity of literature available on pathology of caprine mastitis around the globe.
