RS27_1 – Contagious bovine pleuropneumonia
Synonyms
Contagious bovine pleuropneumonia
Name of the disease in English
Contagious bovine pleuropneumonia
The disease in brief
It is one of the major contagious diseases of cattle; it is listed in the OIE category 1 diseases: Any suspicion must therefore be reported to the DSV; it manifests itself by signs of pneumonia and associated pleurisy; it is caused by Mycoplasma mycoides spp Mycoides SC. It has been eradicated from many countries. The last case in Europe was in Portugal in 1999. but is returning to Europe, in France, Portugal, Spain and Italy and where it has been successfully combated; the threat remains, however, very present.
The disease is transmitted mainly through droplets expectorated by coughing animals. Chronically and asymptomatically infected animals can also excrete the infectious agent (for more than 12 months). Contagion is high (morbidity = 90%) and the already high lethality of 50% with antibiotic treatment increases if no treatment is undertaken.
It is therefore an acute to chronic bronchopneumonia, but which will surprise by its contagion and lethality.
Clinic & diagnosis
When collective pleuropneumonia is observed and an epidemiological link may be possible with areas infected with pleuropneumonia (Africa, Southern Europe, etc.), the disease must be suspected.

Differential diagnosis
-Acute pleuro-pneumonia due to Mannheimia haemolytica RS24.4
-Histophilus pleuropneumone (somnus) N130
-Acute mycoplasma bronchopneumonia RS27
-Poisoning with respiratory manifestation N362
Confirm a suspicion?
Nasal swab or tracheobronchial lavage can isolate the agent by bacteriology or PCR; pleural fluid obtained by puncture or from autopsy samples. The OIE Manual of Diagnostic Tests and Vaccines for Terrestrial Animals describes in detail the diagnostic procedures for CBPP.
Prognosis and treatment
Suspicion of illness that must be reported to the authorities.Control strategies are based on early detection of outbreaks, control of animal movements and a policy of sanitary culling.
Prevention
Prevention is based on the protection of disease-free areas against the importation of the disease and on the early detection of suspicions:
–The protection of disease-free areas is carried out in strict compliance with the rules for importing cattle.
-Early detection of suspicions
