Comparaison de Deux Antigénes de Nature polysaccharidique pour le Diagnostic Sérologique par ELISA de la Pleuropneumonie Porcine (Sérotype 5)

Abstract: Summary Comparison of two polysaccharidic antigens for ELISA serodiagnosis of pig pleuropneumonia (serotype 5) Two antigens of polysaccharidic nature were evaluated for their specificity in serodiagnosis of porcine pleuropneumonia (serotype 5). Recently, long chains lipopolysaccharides (LC‐LPS) was shown to increase the specificity of the ELISA test for A. pleuropneumoniae serotype 5 compared to a saline extract of boiled‐formalinized whole cells. Nevertheless, some cross reactions were noticed with LC‐LPS. We… Show more

“…Ten milligrams (dry weight) of LPS was hydrolyzed at 100°C for 2 h in 1 ml of 1% (vol/vol) acetic acid previously saturated with nitrogen. Lipid A (insoluble) and polysaccharides (soluble) were separated by centrifugation at 12,000 x g for 10 min after neutralization with 5 N NaOH (1). Lipid A was washed and resolubilized in 1 ml of EDTA (20 mM) (26).…”
