Résumé

The standard procedure for the improved cultural recovery of viable Mycobacterium spp. from diverse samples mainly depends on reducing the viability of background microbiota using different chemical compounds. This study was designed to i) evaluate the efficacy and comparison between N-Acetyl-l-Cysteine-Sodium hydroxide (NALC-2% NaOH) and hexadecylpyridinium chloride (0.75% HPC) treatment and exposure time on reducing the viability of undesirable microorganisms with minimal impact on colostrum consistency; and ii) assess the impact of NALC-2% NaOH on improved and enhanced recovery of Mycobacterium avium subsp. paratuberculosis (MAP) in spiked postpartum colostrum samples and consistency of colostrum. A total of 40 samples, each treated with NALC-2% NaOH for 15 min or 0.75% HPC for 5 h, were investigated for total mesophilic aerobic bacteria (MAB) and enterobacteria (EB) (CFU mL
