Assessment of plaque assay methods for alphaviruses
Journal of Virological Methods, 2013Viruses from the Alphavirus genus are responsible for numerous arboviral diseases impacting human health throughout the world. Confirmation of acute alphavirus infection is based on viral isolation, identification of viral RNA, or a fourfold or greater increase in antibody titers between acute and convalescent samples. In convalescence, the specificity

A novel plaque assay system for paramyxoviruses
Journal of Virological Methods, 1989A combination of 5% allantoic fluid and 200 micrograms/ml DEAE-dextran with 30 mM MgCl2 used as a supplement to normal overlay medium was found to give large, clear plaques on monolayers of secondary chick embryo fibroblasts infected with avirulent strains of Newcastle disease virus which did not produce plaques without these additions.

Standardization of a plaque assay for lassa virus
Journal of Medical Virology, 1987AbstractThe plaque reduction neutralization test (PRNT) has been used routinely in serological studies with such arenaviruses as Junin, Machupo, and Parana. However, difficulties have been encountered in using the PRNT for LCM virus, while conflicting views have been expressed about the reliability and efficacy of the test with Lassa virus.

Improved Plaque Assay for Rickettsia tsutsugamushi
The American Journal of Tropical Medicine and Hygiene, 1987The assay of Rickettsia tsutsugamushi infectivity by plaquing has been improved substantially by a number of changes which were based on our understanding of factors which enhance scrub typhus rickettsial infection of, and replication in, cultured cells.

A Micro-Technique for Hemolytic Plaque Assays
The Journal of Immunology, 1974Abstract A method is described for performing hemolytic plaque assays in microculture plates. The technique may be applied to assay in situ the antibody responses of cells cultured in these plates, or to assay the responses of cells obtained from other sources.
