Herpes simplex virus co-infection-induced Chlamydia trachomatis persistence is not mediated by any known persistence inducer or anti-chlamydial pathway [PDF]

Microbiology, 2008
Several inducers of chlamydial persistence have been described, including interferon-gamma (IFN-gamma), IFN-alpha, IFN-beta, and tumour necrosis factor-alpha (TNF-alpha) exposure, and iron, amino acid or glucose deprivation. A tissue-culture model of Chlamydia trachomatis/herpes simplex virus type-2 (HSV-2) co-infection indicates that viral co ...

Persistent Superficial Punctate Keratitis After Resolution of Chlamydial Follicular Conjunctivitis

Cornea, 1992
Two cases of follicular conjunctivitis due to Chlamydia trachomatis followed by punctate epithelial keratitis are described. Both cases were initially treated with either oral tetracycline or doxycycline with resolution of the follicles. These two patients subsequently had recurrent, bilateral grayish lesions at various levels in the corneal epithelium

Presentation of clinically suspected persistent chlamydial infection: a case series

International Journal of STD & AIDS, 2013
In vivo antimicrobial resistance has yet to be documented in Chlamydia trachomatis; however, there have been anecdotal reports of persistent infection. The purpose of this case series was to describe a group of patients who have persistent chlamydia infection despite adequate treatment and where re-infection was considered unlikely.

The persistence of chlamydial inclusions in clinically quiescent trachoma.

West African journal of medicine, 1992
Most of the trachoma patients seen at the Guinness Eye Clinic in Kaduna, Northern Nigeria today are in the healed or quiescent stages of evolution and disease intensity is largely trivial. A significant proportion however, seem to have recrudescence of the active stages, a phenomenon that is usually attributed to reinfection.

[Inapparent persistent chlamydial infection in McCoy cells].

Revue canadienne de biologie, 1981
We have studied the phenomena of inapparent chlamydial infections in vitro using McCoy cells in culture as hosts and low doses of Chlamydia psittaci (GP-IC) as infecting agents. The results indicate that GP-IC can persist undetected at least 220 hrs in McCoy cells previously inoculated with 0.2 mL of a GP-IC preparation containing 30 ifu/mL, using the ...

Chlamydia trachomatis Growth Inhibition by IFNγ: Implications for Persistent Chlamydial Infections

2021
The immune response to chlamydial infections and the role it plays in resistance to reinfection, resolution of ongoing infection, and development of persistent chlamydial infection is poorly understood. Inhibition of chlamydial growth as a result of deprivation of necessary metabolites, such as certain amino acids, has been described previously and ...

Subjects recovering from human ocular chlamydial infection have enhanced lymphoproliferative responses to chlamydial antigens compared with those of persistently diseased controls

Infection and Immunity, 1995
Cell-mediated immune responses to chlamydial and common recall antigens were measured in 26 subjects whose clinical signs of trachoma persisted over 6 months of follow-up and in 21 subjects whose clinical signs resolved spontaneously over the same period.

A case of renal involvement in persistent immune activation caused by chlamydial salpingitis

Virchows Archiv, 2001
A 24-year-old woman presented with renal insufficiency, macrohematuria, and mild urinary protein. Polyclonal hypergamma-globulinemia, thrombocytosis, increased concentration of serum, and urinary interleukin (IL)-6 all indicated persistent immune activation caused by a Chlamydia trachomatis infection of the fallopian tube.

Effect of Expedited Treatment of Sex Partners on Recurrent or Persistent Gonorrhea or Chlamydial Infection

New England Journal of Medicine, 2005
Many sex partners of persons with gonorrhea or chlamydial infections are not treated, which leads to frequent reinfections and further transmission.We randomly assigned women and heterosexual men with gonorrhea or chlamydial infection to have their partners receive expedited treatment or standard referral. Patients in the expedited-treatment group were

Zhonghua nan ke xue = National journal of andrology, 2018
To investigate the epidemic features of persistent genital chlamydial infection (GCI) in Tianjin area.We statistically analyzed the clinical data about the persistent GCI patients received at the Venereal Disease Clinic of Tianjin Medical University General Hospital from 2009 to 2011.A total of 158 patients with persistent GCI were received from ...
