If a cattle is showing increased respiration and blood mixed foamy discharge from mouth, nose and anus, it is likely to be suffering from
Anthrax is a fatal disease which commonly effects humans and cattle. It is caused by spores of bacteria Bacillus anthracis. These spores remain in soil for decades and are also found in bloody discharges of infected animals and can spread to other animals easily.
Clinical signs depend on species of cattle effected. If infection occurs through mouth or nose the symptoms are shown immediately and death occurs rapidly. If infection occurs through skin there will not be acute symptoms but later becomes generalized. If infection is less acute symptoms may be having difficulty in breathing, tremble, collapse and die. Nearby death blood oozes from openings of animal. When infection is localized to throat area, the neck swells and bloody discharge comes from mouth.
So, the correct answer is 'Anthrax'.
