Streptococcus bovis is a group of strains of Gram-positive bacteria, originally described as a species, [5] [6] that in humans is associated with urinary tract infections, endocarditis, sepsis, [7] and colorectal cancer. [8] S. bovis is commonly found in the alimentary tract of cattle, sheep, and other ruminants, [9] and may cause ruminal acidosis.

Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. [1] As such, the diseases of these animals are of great economic importance to humans.
Definite diagnosis of brucellosis requires the isolation of the organism from the blood, body fluids, or tissues, but serological methods may be the only tests available in many settings. Positive blood culture yield ranges between 40 and 70% and is less commonly positive for B. abortus than B. melitensis or B. suis .
F. necrophorum is also a cause for lameness in sheep. Its infection is commonly called scald or foot rot. It can last for several years on land used by either sheep or cattle, and is found on most land of this type throughout the world. Due to its survival length in these areas, it is unrealistic to try to remove it.
It is a complex, bacterial or viral infection that causes pneumonia in calves which can be fatal. It also affects many other species of feedlot animals like sheep and pigs, but is most prominent in calves. [2] The infection is usually a sum of three codependent factors: stress, an underlying viral infection, and a new bacterial infection. [3]
Cryptococcosis is a potentially fatal fungal infection of mainly the lungs, presenting as a pneumonia, and in the brain, where it appears as a meningitis. [4] [9] [12] Coughing, difficulty breathing, chest pain and fever are seen when the lungs are infected. [5]
About four million cows were killed during the eradication programme in the UK. [11] Four cases were reported globally in 2017, and the condition is considered to be nearly eradicated. [1] In the United Kingdom, more than 184,000 cattle were diagnosed from 1986 to 2015, with the peak of new cases occurring in 1993. [3]
