Abstract
Ovine Enzootic Abortion (OEA) is caused by Chlamydia abortus and has recently been recognized as endemic in Mexico. Due to the impact of OEA on intensive lamb production, it is necessary to establish a sanitary control plan based on an efficient diagnosis. The loop-mediated isothermal amplification technique (LAMP) is a molecular test that can specifically identify C. abortus. The aim of this study was to standardize the LAMP technique for the specific detection of C. abortus from ovine vaginal exudate. Primers were identified and modified from an electronic database. The effective conditions of the technique were determined using synthetic DNA and positive biological samples by PCR as references. The assay detection limit was 1 × 10-5 of genetic material, equivalent to 8.5 copies. The standardized LAMP test is proposed as a novel molecular tool for the rapid and specific diagnosis of C. abortus infection from ovine vaginal exudate samples in Mexico.
