How is Actinobacillus Pleuropneumoniae treated?
Commonly used agents used for prevention and/or treatment include tiamulin, tulathromycin, chlortetracycline, ceftiofur, tilmicosin, florfenicol, enrofloxacin and procaine penicillin G. Many strains are resistant to tetracyclines. Chronic cases usually are unresponsive to treatment.

What causes actinobacillus Pleuropneumoniae?
Epidemiology. Swine that survive acute APP often remain carriers. Swine can also be subclinically infected carriers with only occasional disease outbreaks. Most transmission is by direct contact of APP via nasal secretions but transmission may be via aerosol, at least for short distances.
What is the meaning of pleuropneumonia?
