Anaerobic and aerobic bacterial flora of acute conjunctivitis in children
Insights
Anaerobic bacteria were frequently isolated from pediatric acute conjunctivitis cases, often alongside aerobic bacteria. These findings highlight the role of anaerobic organisms in pediatric eye infections.
Area of Science:
- Ophthalmology
- Microbiology
Background:
- Acute conjunctivitis is a common pediatric eye infection.
- The role of anaerobic bacteria in conjunctivitis is not fully understood.
Purpose of the Study:
- To investigate the prevalence and types of anaerobic bacteria in pediatric acute conjunctivitis.
Main Methods:
- Collected aerobic and anaerobic cultures from 126 pediatric patients with acute conjunctivitis.
- Collected cultures from 66 healthy controls.
- Analyzed bacterial isolates and clinical data.
Main Results:
- Anaerobes were isolated from 37.3% of conjunctivitis patients.
- Anaerobes were found in mixed cultures with aerobes in 20.6% and as sole isolates in 16.7%.
- Significant bacterial isolates included Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, and anaerobic Gram-positive cocci.
Conclusions:
- Anaerobic bacteria are frequently involved in pediatric acute conjunctivitis.
- Specific aerobic and anaerobic bacteria are significantly associated with conjunctivitis in children.
Abstract:
Aerobic and anaerobic cultures and clinical data were obtained from 126 pediatric patients with acute conjunctivitis. Similar cultures were obtained from 66 persons who did not have a conjunctival inflammation. Anaerobes were isolated from 47 patients (37.3%). In 26 cases (20.6%), they were in mixed cultures with aerobes, and in 21 cases (16.7%), they were the only isolates. Aerobes alone were recovered in 72 patients (57.1%). No bacterial growth was noted in seven patients (5.6%). The organisms recovered from eyes with conjunctivitis in statistically significant numbers were Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, and anaerobic Gram-postive cocci.
