[Relationship between the Demodex and bacteria infection in human rosacea]
1Department of Parasitology, Medical college of Inner Mongolia National University, Tongliao 028041, China.
Objective:
To understand the relationship between Demodex and bacteria infection in rosacea (brandy nose), and to find effective means for the treatment.
Methods:
Cellophane tape was used to detect Demodex on the nasolabial grooves and the face; sebum and tissue on face was scraped and cultured to examine bacteria under microscope. The hospital-made anti-rosacea lotion was used on the affected part two times a day for 7 days.
Results:
It was found that 193 (74.2%) of 260 cases with rosacea were infected by Demodex and 209 (80.4%) of the patients were infected by bacteria. The overall effective rate of the treatment for rosacea was 73.5%.
Conclusion:
Bacteria infection in rosacea is an important factor inducing rosacea. The curative effect of the anti-rosacea lotion is good.
