Worldwide bovine mastitis (clinical and subclinical) is one of the most important diseases causing considerable economic loss to the farmers in dairy industry. The causative organisms of mastitis are ubiquitous in nature and persist long time in the cow yard or barns. Reduction in milk Production in subclinical mastitis (SCM) is not only a reason of great economic loss to the dairy industry but also acts as a carrier & source of infection for the healthy milch cows which is one of the biggest obstacle in the achievement of self-sufficiency in milk production in Bangladesh. On the other hand, control of this disease by successful treatment in dairy animals depends to a great extent on the type of infection, proper selection & administration of drugs. This book is emphasized on the major bacterial profiles causing different grades of subclinical mastitis along with their isolation, identification and characterization. Find out in vitro the antibiotic sensitivity pattern of the bacterial isolates. This book will provide a clear guideline to the practitioner and policy maker to prevent indiscriminate use of antibiotics and ultimately avoid antibiotic hazard in animal health.

Brucellosis, worldwide the most important zoonosis and remains a major health problem. This bacterial pathogen is also classified by the Centers for Disease Control and Prevention (CDC) as a category (B) pathogen that has the potential for development as a bioweapon. After tuberculosis, brucellosis is the most important bacterial disease of livestock in Bangladesh. There are sporadic reports of prevalence of brucellosis in cattle, goats, sheep, buffalo and including human. Detailed epidemiological studies are essential to design an appropriate control strategy for the disease. The book, therefore, illustrates the true prevalence, distribution and risk factors of brucellosis, guidelines and methods of isolation and characterization of Brucella spp. from infecting ruminants. The exciting new study shows a new way of developing the livestock and public health policy of government as well as professionals, prevention and control of brucellosis nationally and at international level to improve livelihoods. On other hand anyone else who have interest on the epidemiology of brucellosis.
