چکیده

Materials and methods: Two L intracellularis isolates were tested for susceptibility to several classes of disinfectants, including iodine, a biguanide, phenol, an oxidizing agent, a quaternary ammonium compound (QAC), and the combinations of QACs with aldehydes (formaldehyde and glutaraldehyde). All disinfectants were diluted with simulated hard water by adding 400 or 1000 ppm of calcium carbonate (CaCO3) and 5% fetal bovine serum (FBS). The effects of disinfectant concentrations (0.5×, 1×, and 2× the recommended dose) and exposure times (10, 30, and 60 minutes) at each concentration were investigated.

Studies on the ex vivo survival of Lawsonia intracellularis

Methods: Two co-cultured strains of L. intracellularis were suspended in vitro for 30 minutes at 20°C in various disinfectants according to label recommendations for usage, then washed in saline. Disinfectanttreated and Control bacteria were then added to fresh cells for co-culture for a standard 5-day incubation. Further cell-free suspensions were exposed to air at 5°C, 20°C, or 37°C for up to...

Seroprevalence of Lawsonia intracellularis antibodies in intensive pig farms in China

BACKGROUND Porcine proliferative enteropathy caused by Lawsonia intracellularis (L. intracellularis) is a major concern to the pig industry worldwide. Although 8.3 billion pigs are produced each year in China, few reports on the prevalence of L.intracellularis infection are available. The aim of the current study was to estimate the seroprevalence of L. intracellularis antibodies in intensive p...

Antigenic and functional profiles of a Lawsonia intracellularis protein that shows a flagellin-like trait and its immuno-stimulatory assessment

The obligate intracellular Lawsonia intracellularis (LI), the etiological agent of proliferative enteropathy (PE), is an economically important disease in the swine industry. Due to extreme difficulty of in vitro culture of the pathogen, molecular characterization of protein components of LI that are targets of the immune system, is difficult; thus, the scientific evidence to drive the developm...
