Pasteurella multocida is pathogenic for many animals, causing fowl cholera, blood poisoning in ruminants, pneumonia in young cattle, and respiratory infection in cattle and humans.
Four species of the genus Brucella are pathogenic for humans, namely B. melitensis (from sheep and goats), B. abortus (from cattle and other bovidae), B. suis (from pigs), and B. canis (from dogs) [ 14].
Four of 6 nomen species of the genus Brucella are pathogenic for humans, i.e., B. melitensis (transmitted from sheep and goats), B. abortus (from cattle and other bovidae), B. suis (from pigs), and B. canis (from dogs) (2 ).
The isolates (n = 6) were pathogenic for sea bass.
For example, M. dispar is potentially pathogenic for cattle [ 32] but cannot be grown on the culture media commonly used in laboratories, neither can Mccp, the etiological agent of CCPP, a disease currently absent from France.
M. bovirhinis is commonly found as a part of the normal respiratory tract microflora of cattle and is not considered to be pathogenic.
The different prevalence of the infection in goats and cattle has led to speculations about the existence of M. a. paratuberculosis strains that are non-pathogenic for cattle.
This difference in prevalence between goats and cattle has led to speculations about the existence of a Mycobacterium avium subsp. paratuberculosis (M. a. paratuberculosis) isolate that is non-pathogenic for cattle.
The classification definitions for pathogenicity are: Pathogenic, Suspected Pathogenic, Benign, Suspected Benign, or Uncertain.
