Detection of cytomegalovirus in urine by the shell-vial technique: usefulness of diluting the sample

, : Detection of cytomegalovirus in urine by the shell-vial technique: usefulness of diluting the sample. Enfermedades Infecciosas Y Microbiologia Clinica 9(9): 561-563

To assess the toxicity of urine samples on human fibroblast cell monolayer using Shell-vial technique for cytomegalovirus antigen detection. A total of 227 urine samples were processed, inoculated on Shell-vial simultaneously, being either diluted (1:1) and non diluted in transport media. After 24-48 hours incubation, the fibroblast cells monolayer was stained using fluorescein-marked monoclonal anti-cytomegalovirus antibodies. Cytomegalovirus was detected in 9.6% of samples inoculated with diluted urine, and in 5.2% of samples inoculated with non-diluted urine. Destruction of monolayer cells was seen in 13.2 and 22.4, respectively. With Shell-vial technique for detecting cytomegalovirus in urine samples, a high number of positive results was obtained using diluted urine. Also a significant minor destruction of cells monolayer was observed with the same inoculum.

The high-risk human papillomavirus (HPV) E6 and E7 proteins act cooperatively to mediate multiple activities in viral pathogenesis. For instance, E7 acts to increase p53 levels while E6 accelerates its rate of turnover through the binding of the c...
