[Relationship between the Demodex and bacteria infection in human rosacea].

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.
