All environmental factors were recorded as housing condition, breeding, health problems, production and feeding. Morphological examination of the udder were carried out. Milk samples of infected goats, were collected for bacterial isolation and sensitivity test. Animals were treated with systemic and local intramammary broad spectrum antibiotic. The results indicated that, 35 cases (70 %) were responded to treatment, and showed normal reproductive and productive performances.15 cases (30 %) of chronic mastitis do not respond to treatment and breeding. Post-mortem examination of these cases revealed widespread diffused chronic mastitis throughout the affected udder. Tissue specimens of infected udder and supra mammary lymph node were fixed in 10% formalin for histopathological examination. Bacteriological examination revealed isolation of Staph aureus, Corynebacterium pyogenes, Salmonella spp., E coli in a single or mixed with other bacteria as Pasteurella spp. Fungus suspect Asperigillus spp. infection and yeast, suspect Candida spp. Pathological examination revealed chronic diffused suppurative and chronic granulomatous mycotic mastitis.
