Mycoplasma bovis (M. bovis) is an important bovine mycoplasma implicated in economically important clinical diseases, such as respiratory diseases, otitis media, and mastitis. The prevalence of M. bovis-associated mastitis in both cattle and buffaloes has been increasingly recognized as a global problem. High morbidity rates and consequential economic losses have been devastating to the affected cattle and buffalo farms, especially those in developing countries. Therefore, a rapid and accurate method is urgently needed to detect M. bovis. In this study, a rapid and simple lateral flow strip for detecting antibodies against M. bovis was established that used carbon nanoparticles (CNPs) as the labelled materials. The results from the test strip were highly consistent with those from ELISA. The test showed high specificity (100%) and no cross-reaction with other bovine pathogens. The detection sensitivity of the test was also relatively high (97.67%). All the results indicated that the colloidal carbon test strip could serve as a simple, rapid, sensitive, and specific diagnostic method for detecting antibodies against M. bovis at cattle farms.
