BHK-21 cells and HeLa cells were as sensitive as irradiated McCoy cells for titrating both fast- and slow-growing strains of TRIC agents. BHK-21 cells were as efficient as irradiated McCoy cells for isolating TRIC agents from trachoma and from the genital tract of patients with non-gonococcal urethritis. More inclusions were formed in BHK-21 than in irradiated McCoy cells.
The case described here represents the first laboratory-confirmed case of inclusion blennorrhea at the Mayo Clinic since laboratory isolation of Chlamydia trachomatis was instituted in 1974. Treatment with a sulfonamide preparation proved effective. Further aspects of the diagnosis and treatment of inclusion blennorrhea are discussed.
In terms of the rate of positive diagnoses the indirect fluorescent antibody (FA) test was rather more effective than iodine for demonstrating trachoma (TRIC) inclusions in conjunctival scrapings, but the degree of advantage was not statistically significant. In duplicate scrapings stained at random by one or the other method, FA staining yielded the higher inclusion count significantly more often than did iodine. Some inclusions that failed to stain with FA were found on subsequent staining with Giemsa. A method is described for improving the post-FA Giemsa staining of conjunctival smears stored at subzero temperatures. Given adequate facilities, the FA stain is preferable to iodine for demonstrating TRIC inclusions in the conjunctiva; but the iodine method, properly used, holds advantages for field use.
Human seminal plasma inhibited formation of strain LB-1 chlamydial inclusions in McCoy cells proportional to the concentration of seminal plasma added after chlamydial adsorption.
In BHK 21 cells infected with more than one TRIC organism the inclusions coalesce so that 30 hr. after infection only one inclusion per cell remains. Six hours after infection the cells are as susceptible to further infection as uninfected cells.
A hugh episcleral traumatic conjunctival inclusion cyst enveloping almost the whole eye, which appeared in the left phthisical eye of a young woman who sustained a perforating ocular injury a few years before enucleation, is described.
In 15 Keratoconic patients with papillary conjunctivitis associated with wearing rigid polymethylmethacrylate contact lenses, the cleaning of the lenses with enzymatic contact lens cleaner (papain) increased lens wearing time in nine and diminished the symptoms of mucus and itching in 12. In 13 control, lens-wearing keratoconic subjects with papillary conjunctivitis, three had a decrease, four had an increase, and six had no change in lens wearing time and one had a diminution of symptoms. Use of the enzymatic contact lens cleaner did not, however, influence the biomicroscopic appearance of the papillary conjunctivitis. The inclusion of the enzymatic contact lens cleaner in the cleaning regimen offered an adequate improvement in wearing time and tolerance for three of four patients that previously suffered a reduction in wearing time that compromised or precluded their vocational responsibilities.
Among 2,700 babies born in a maternity hospital there were 71 (2.6%) cases of eye sepsis, mostly mild. Forty-four of these cases were screened for inclusions of TRIC agent. Four certain positives and a further four very suggestive cases were found-an incidence of 18% of the cases of eye sepsis investigated. The true incidence is probably somewhat higher.Follow-up showed that even minimal and transitory eye sepsis from TRIC infection in the neonate can lead to permanent scarring of the conjunctiva and cornea, with or without pannus.
