This study was aimed to evaluate and compare the duplex PCR versus the nested PCR, for detection of Brucella spp. (BR) and Mycobacterium spp. (TB). A total of 100 samples of tissues from tracheo-bronchial lymph nodes, bovine lung and bacterial isolate as positive controls were used. Were evaluated ten combinations of primers which were designed to flank the segment of the 16S rRNA sequence (RB) and antigen gen MPB70 (TB), the best result for the Duplex PCR was obtained with the primers Bru-2F/Bru-2R for BR and Tub-1F/Tub-N-R for TB. The amplification of the products was 225 and 230-bp respectively. In order to compare the results of the proposed technique, all samples were initially analyzed and compared between PCR and nested PCR (Kappa, k = 0.85) and the concordance between Duplex PCR and nested PCR (k = 0.88) for the two bacteria was very good.La tuberculosis y la brucelosis siguen siendo causas importantes de morbilidad y mortalidad en muchos países, para la detección de ambas enfermedades se requieren de herramientas eficientes y sensibles para efectivizar el diagnóstico. Este trabajo fue dirigido a evaluar y comparar la técnica de Dúplex PCR frente a la PCR anidada, para la detección de Brucella spp. (BR) y Mycobacterium spp. (TB). Se utilizó un total de 100 muestras de tejidos a partir de nódulos linfáticos traqueo bronquiales, pulmón de bovinos y, aislados bacterianos de TB y BR como controles positivos. Diez combinaciones de iniciadores dirigidos a flanquear un segmento de la secuencia 16S ARNr (BR) y el gen antígeno MPB70 (TB) fueron evaluados, el mejor resultado para la Dúplex PCR se logró con los iniciadores Bru-2F/Bru-2R para BR y para TB, Tub-1F/Tub-N-R. Los productos de amplificación fueron de 225 y 230-pb respectivamente. A fin de potencializar los resultados de la técnica propuesta, todas las muestras fueron inicialmente analizadas y comparadas entre la PCR simple y la PCR anidada (Kappa, k = 0,85) y, la concordancia entre los resultados obtenidos con la PCR anidada y la Dúplex PCR (k = 0,88), para las dos bacterias fue muy buena.Universidad Nacional de Trujillo2013-04-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.unitru.edu.pe/index.php/scientiaagrop/article/view/9610.17268/sci.agropecu.2013.01.04Scientia Agropecuaria; Vol. 4 No. 1 (2013): January - March; 37-43Scientia Agropecuaria; Vol. 4 Núm. 1 (2013): Enero - Marzo; 37-432306-67412077-9917reponame:Revista UNITRU - Scientia Agropecuariainstname:Universidad Nacional de Trujilloinstacron:UNITRUspahttp://revistas.unitru.edu.pe/index.php/scientiaagrop/article/view/96/14Derechos de autor 2013 Scientia Agropecuariainfo:eu-repo/semantics/openAccess2021-06-01T15:35:14Zmail@mail.com -
