Abstract:
Brucellosis is a zoonotic infection transmitted from animals to humans by the ingestion of infected food products, direct contact with infected animal or inhalation of aerosols. Brucella is a facultative intracellular pathogen that has the ability to survive and multiply in the phagocytes and cause abortion in cattle and undulant fever in humans. Brucella spp particularly B. melitensis, B. abortus, and B. suis represent a significant public health concern. At present, B. melitensis is the principle cause of human brucellosis in India. Late aborted fetuses, may be born alive but either die shortly after birth or are weak, unthrifty, and at risk of succumbing to calf diarrhoea. Most cows that abort have RFM. The placenta appears dry, thickened, cracked, and covered by a yellowish exudate in the inter cotyledonary areas. Efforts are directed at detection and prevention, because no practical treatment is available. Eventual eradication depends on testing and eliminating reactors. The disease has been eradicated from many individual herds and areas by this method. Herds must be tested at regular intervals until two or three successive tests are negative vaccination of calves with B abortus Strain 19 or RB51 increases resistance to infection.
