A study to identify the practices of the buffalo keepers which inadvertently lead to the spread of brucellosis in Delhi.

Background: India has the largest Buffalo population in the world, with every household in rural India owning buffaloes depending upon daily milk requirement - dairy farmers can own between 10 to 70 buffaloes. The health of Indian buffaloes is of economic importance since India is one of the largest buffalo meat exporters in the world, and Indian Buffalo semen is sold in the USA for breeding purposes. However, National Control Program on brucellosis is only active in South India and in Panjab (a North Indian state with high human brucellosis incidence).
