A description of the original irradiated McCoy cell system and the simplified, sensitive technique using cycloheximide-treated McCoy cells are given in this paper. In contrast to earlier techniques employing such cells, no pretreatment of the cells was used. 1981 Jun;13(6):1036-9. doi: 10.1128/jcm.13.6.1036-1039.1981. Five isolates of the trachoma agent have been made by culture in irradiated McCoy cells, without use of the standard method of yolk sac inoculation, with no indication that successful passage in cell culture was accompanied by adaptation to yolks sac. A new cell culture method was developed for the diagnostic isolation of Chlamydia trachomatis using McCoy cells pretreated with mitomycin-C. This drug acts on the cell by producing cross links between strands of DNA and results in the production of large, flat cells, which are similar to irradiated cells, and large chlamydial inclusions. Once the specimen has been inoculated, 2μg/ml of cycloheximide should be added to the growth medium to suppress protein synthesis by the host eukaryotic cell (47). eCollection 2018.

These specimens were shaked vigorously on a vortex mixer for releasing elementary bodies from intact host cells and inoculated in monolayer of McCoy cell. J Clin Microbiol. Results: The prevalence of Chlamydia trachomatis infection among infertile women was high, at 15.0%. Monolayers of these cells proved as efficient as irradiated cells for the growth of three different serotypes of Chlamydia trachomatis and for the primary isolation of chlamydiae from clinical specimens obtained from patients attending a venereal disease clinic. McCoy cells treated in six different ways, in addition to untreated cells, were compared to determine which gave rise to the largest number of Chlamydia trachomatis inclusions when tested with a . Dilute high titer stocks to avoid cell toxicity. 6. The study suggested that sialic acid residues on the cell surface may be specific receptors for TRIC organisms, but not by inactivated lymphogranuloma venereum or influenza virus. At UI, the swab in 1.3 mL of Chlamydia Transport Medium was brought to room temperature and, after vortexing, 0.50mL of the medium was added to McCoy cell monolayers in shell vials. Monolayers were then fixed and chlamydial IFU were stained with a C. muridarum -specific mAb 40 recognizing the . 3.3.1 Preparation of McCoy cell culture plates (McCoy Plates) 1. A method of cell culture using HeLa 229 cells treated with DEAE-dextran was found to be successful in the primary isolation of trachoma-inclusion conjunctivitis (TRIC) organisms.

McCoy cells are available commercially and from the American Type Culture Collection. Cells maintained in calf serum from this batch supported the growth of two laboratory strains of Chlamydia trachomatis, a genital strain (E/UW-5/Cx) in McCoy cells and a lymphogranuloma venereum strain (440L) in HeLa cells. The addition of ovoTF to the culture medium had no effect on bacterial replication, but the addition of 0.5 or 5 mg/mL of bLF significantly reduced the inclusion size by 17% and 15% respectively.

The incidence of cervical infection with Chlamydia trachomatis is two to three times that of gonorrhea: 4% to 9% in private office settings, 6% to 23% in family planning clinics, and 20% to 30% in sexually-transmitted diseases clinics. 1969 Oct;120(4):451-62 Different McCoy cell lines exist and some have reduced susceptibility to chlamydial infection. 4.1 Cell culture, Chlamydia propagation and infections HeLa 229 and McCoy cells, were routinely grown in RPMI 1640 media supplemented with 10% FBS (HyClone, Thermo Fisher Scientific, Rockford, IL) and 2 mM L‐glutamine (HyClone), at 37°C with CO 2. [PubMed: 4110420] that ionizing radiation (cobalt-60) greatly increased the susceptibility of McCoy cells to infection by chlamydia strains. The amino acid requirements of Chlamydia trachomatis were defined in McCoy cell monolayer cultures, depleted of their nutrient reserves by maintenance in Earle balanced salt solution for at least 2 days, and then treated at infection with 1 μg of cycloheximide per ml, an inhibitor of host cell protein and deoxyribonucleic acid synthesis.

Found inside – Page iThe book identifies the components of an effective national STD prevention and control strategy and provides direction for an appropriate response to the epidemic. This property makes Chlamydia difficult organisms to grow and maintain in the laboratory. Plates were centrifuged for 1 hour at 1500 [micro] to synchronize the infection. As a result, Chlamydia cannot be grown on conventional bacteriological medium. LGV II strain 434 was initially accessioned as an egg passaged preparation (VR-902) and subsequently adapted to cell culture at ATCC and reaccessioned as VR-902B. This medium will support the growth of primary mammalian cells derived from normal bone marrow, skin, spleen, kidney, lung, rat embryos, and other tissues.
