Ceva 'Spotlight The Future' newsletter April 2019
This month read about lung lesions, lung scoring and Actinobacillus pleuropneumoniae.
Coglapix: interest of lung scoring together with serological profiling of the herd
Lung scoring together with serological profiling of the herd is a useful approach to assess prevalence and severity of some important respiratory pathogens and determine a most efficient vaccination programme. Dr Andrea Luppi from Izsler Institute is sharing the main conclusion of a large epidemiological study performed in Italy. This study demonstrates that:
- The Enzootic pneumonia (EP)-like lesions average values show significant associations with the intra herd seroprevalence for M. hyo at 18 weeks of age, confirming a good correlation between the EP like lesions recorded at the slaughter house and previous M.hyo infection.
- Dorso-caudal pleurisy average value and Actinobacillus pleuropneumonaie index (API) are significantly associated to A. p. herd seroprevalence.
- These evaluations confirm once again the importance of the scoring of the lungs at the slaughterhouse, in order to discover pleural lesions due to sub-clinical cases and bronchopneumonia lesions, otherwise often under estimated.
Actinobacillus pleuropneumoniae serology with Professor Marcelo Gottschlak
Can LPS specific or Apx specific ELISAs be used for monitoring the vaccine uptake or vaccine efficacy? Can any correlation between the amount of circulating antibodies and protection be determined?
Professor Marcelo Gottschalk from university of Montreal reply to our questions regarding the App serology in general.
Lung lesions in slaughter pigs in 2017
Lung problems are commonplace in many swine farms around the globe. Where exactly are the problems the worst, what causes them and can research help to provide benchmarks? A continent-wide survey provided insightful results.
