In vitro susceptibility of cytomegalovirus isolates from immunocompromised patients to acyclovir and ganciclovir. 1987

N L Cole, and H H Balfour

Fifty-four isolates of cytomegalovirus (CMV) from 25 immunocompromised patients with CMV infections were examined in a plaque reduction assay to determine in vitro susceptibilities to both acyclovir and ganciclovir. Isolates were approximately 25-fold more sensitive to ganciclovir than to acyclovir. The mean +/- SD ID50 for all isolates to acyclovir was 63.1 +/- 30.2 microM, (median, 52.3 microM; range, 16.7-146.4 microM). The mean ID50 for all isolates to ganciclovir was 2.50 +/- 1.27 microM, (median, 2.15 microM; range, 0.65-7.11 microM). Exposure to acyclovir or ganciclovir for periods of 2-5 wk did not alter the mean susceptibility of clinical isolates. However, one CMV strain isolated from a renal transplant patient after 14 days of acyclovir therapy displayed the lowest susceptibility of all strains tested (acyclovir 146.4 microM; ganciclovir 7.11 microM) and may represent selection of a resistant virus population.

UI	MeSH Term	Description	Entries
D007108	Immune Tolerance	The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc.	Immunosuppression (Physiology),Immunosuppressions (Physiology),Tolerance, Immune
D010948	Viral Plaque Assay	Method for measuring viral infectivity and multiplication in CULTURED CELLS. Clear lysed areas or plaques develop as the VIRAL PARTICLES are released from the infected cells during incubation. With some VIRUSES, the cells are killed by a cytopathic effect; with others, the infected cells are not killed but can be detected by their hemadsorptive ability. Sometimes the plaque cells contain VIRAL ANTIGENS which can be measured by IMMUNOFLUORESCENCE.

D003587	Cytomegalovirus	A genus of the family HERPESVIRIDAE, subfamily BETAHERPESVIRINAE, infecting the salivary glands, liver, spleen, lungs, eyes, and other organs, in which they produce characteristically enlarged cells with intranuclear inclusions. Infection with Cytomegalovirus is also seen as an opportunistic infection in AIDS.

D000998	Antiviral Agents	Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.
