Which of the following diseases of milching animals are infectious? 1. Foot and Mouth disease 2. Authraz 3. Black Quarter 4. Cowpox Select the correct answer :

All four listed diseases are infectious. Foot-and-mouth disease is caused by the FMD virus and is a highly contagious viral disease of cloven-hoofed animals [1]. Anthrax (referred to as “Authraz” in the question) is caused by Bacillus anthracis and is an infectious bacterial disease affecting livestock and wildlife [1]. Blackquarter (blackleg) is a bacterial clostridial disease listed among infectious bovine diseases in veterinary manuals and control lists [2]. Cowpox is a zoonotic viral infection (related to orthopoxviruses) that infects animals and can transmit to humans, and is described as an infectious disease in clinical overviews [3]. Hence, all four are infectious diseases of milking animals.
