Desenvolvimento de uma metodologia de pcr semiquantitativa utilizando plasmídio clonado com parte do gene gb de citomegalovírus

Abstract: RESUMO: A infecção por citomegalovírus é disseminada em nosso meio e costuma acometer, com significante morbimortalidade, indivíduos imunodeprimidos, especialmente, transplantados de medula óssea e de rim bem como pacientes com AIDS. Neste trabalho, descrevemos o desenvolvimento de uma PCR semiquantitativa para detectar e quantificar cargas de CMV, presentes em materiais clínicos. Para tanto, inserimos em plasmídios PCR II (Invitrogen, USA), o fragmento com 296 pares-base do gene da glicoproteína B do CMV. Os … Show more

“…In recent years, PCR has been widely used in the detection of the HCMV genome, with greater sensitivity compared to that of viral isolation in cell cultures. PCR can provide quantitative and qualitative results with certain advantages, such as greater flexibility with samples, storage at -20ºC and the possibility of repeating tests 6,7 . The use of PCR with peripheral blood leukocytes is also more appropriate in cases of small loads, such as when antiviral therapy is already in progress 4 .…”
