Cultivation of Chlamydia trachomatis in cycloheximide-treated mccoy cells.
An isolation technique for Chlamydia trachomatis using McCoy cells is described. In contrast to earlier techniques employing such cells, no pretreatment of the cells was used. The glutarimide antibiotic cycloheximide was added to the culture medium used for incubating the cells after infection. Cycloheximide was used at concentrations that depressed, but did not completely inhibit, the metaboli...
متن کاملSurvey on Carrier State of Sheep in Chlamydia pecorum Infection
Over the last 40 years, evidence has accumulated to suggest the ubiquitous presence of infections with intracellular bacteria of the genus Chlamydia in different livestock species. Different methods to clinical specimens substantiated such widespread, but mostly clinically unapparent, presumably low-level infections. In this initial epidemiological study, we addressed the question of chlamydial...
متن کاملA comparison of the sensitivity of immunofluorescence and Giemsa for staining Chlamydia trachomatis inclusions in cycloheximide-treated McCoy cells.
In a clinical study of 190 men with non-gonococcal urethritis, Chlamydia trachomatis inclusions were sought in cycloheximide-treated McCoy cells by an indirect immunofluorescent antibody technique. The method was consistently reliable over a period of two years, and the results were obtained within 24 hours of a patient's attendance. The results correlated with those obtained by Giemsa staining...
متن کاملImproved method for isolation and growth of Chlamydia trachomatis in McCoy cells treated with cycloheximide using polyethylene glycol.
The sensitivity of non-replicating McCoy cells pretreated with polyethylene glycol for the isolation of Chlamydia trachomatis from clinical specimens and for the growth of a laboratory strain was compared with the sensitivity of untreated non-replicating cell cultures. The concentration of polyethylene glycol in different solutions and the time of addition to the cell culture medium were critic...
متن کاملPersistent infection of mouse fibroblasts (McCoy cells) with a trachoma strain of Chlamydia trachomatis.
An in vitro model of persistent infection of mouse fibroblasts (McCoy cells) with a trachoma strain (G17) of Chlamydia trachomatis has been developed. Persistently infected cultures were established by infecting McCoy cells with high multiplicities of chlamydiae. After the first cycle of chlamydial replication, the host cells multiplied more rapidly than the parasites, so that the fraction of i...
