Published on: August 12, 2020
Virus isolated from inclusion conjunctivitis of newborn (inclusion blennorrhea)
Insights
A novel virus causing infant conjunctivitis was isolated from an infant's eye discharge. This agent, resembling trachoma virus, successfully induced similar symptoms in monkey eyes.
Area of Science:
- Ophthalmology
- Virology
- Neonatal Medicine
Background:
- Acute conjunctivitis is a common neonatal infection.
- Inclusion conjunctivitis in infants can be caused by Chlamydia trachomatis.
- The etiology of some conjunctivitis cases remains unclear.
Purpose of the Study:
- To identify the causative agent of acute conjunctivitis in a neonate.
- To characterize the isolated pathogen and its potential to cause disease.
Main Methods:
- Microscopic examination of conjunctival discharge for elementary-body inclusions.
- Viral culture from conjunctival scrapings using embryonated eggs.
- Experimental induction of conjunctivitis in monkey eyes.
Main Results:
- Typical elementary-body inclusions were observed in the infant's discharge.
- A virus, similar to trachoma virus, was successfully isolated and cultured.
- Instillation of the cultured virus into monkey eyes caused acute conjunctivitis.
Conclusions:
- A viral agent, distinct from Chlamydia, was implicated in this case of infant conjunctivitis.
- The isolated virus demonstrated pathogenicity in an animal model.
- Further investigation is needed to understand the prevalence and characteristics of this viral pathogen.
Abstract:
An infant developed acute conjunctivitis 7 days after birth. Smears of the mucopurulent discharge contained many typical elementary-body inclusions. From conjunctival scrapings a virus resembling trachoma was grown in eggs. When instilled into monkey eyes, it produced an acute conjuctivitis resembling the human disease. Nine other patients with inclusion conjunctivitis of similar intensity failed to yield viruses.
