The CYP2D6 gene metabolizes approximately 25 % of drugs of clinical use and exhibits a marked genetic variation, thus according to the allelic variants carried by each individual three types of metabolism can be observed: poor (PM), extensive (EM) or ultrarapid (UM). There is also interethnic variation in the frequencies of PM, EM and UM individuals. Knowledge of the individual CYP2D6 metabolic status may be clinically and economically important and could provide the basis for a rational approach to drug prescription.

El gen CYP2D6 metaboliza aproximadamente el 25% de fármacos de uso clínico y exhibe una marcada variación genética, por lo que como resultado de las variantes alélicas que porte cada individuo se pueden presentar tres tipos de metabolismo: lento (PM), rápido (EM) o ultrarrápido (UM). Dependiendo del origen étnico de la población se han observado diferencias en las frecuencias de individuos PM, EM y UM. El conocimiento individual del fenotipo CYP2D6 es clínica y económicamente importante, ya que disminuye el riesgo a reacciones adversas y proporciona las bases para una mejor prescripción farmacológica.

In order to standardize a rapid method for detecting C. jejuni in chickens, it was taken cloacal swabs from 50 chickens of seven-week lifetime belonging to several markets of Lima's city. DNA was extracted by using organic solvents and the presence of C. jejuni was detected by means of Nested-PCR using specific primers for 16S ribosomal and hipO genes. In parallel with this rapid DNA-based approach, it was isolated C. jejuni by conventional filtration bacteriological methods and selective culture mediums. The rapid and conventional methods used in this study, detected C jejuni in 48/50 (96%) and 29/50 (58%) respectively. These findings indicate than the rapid method has a higher sensitivity lhan the conventional one.
