Effect of secondary infection on epithelialisation and total healing of cutaneous leishmaniasis lesions
BACKGROUND Cutaneous leishmaniasis (CL) generally presents with a single or several localised cutaneous ulcers without involvement of mucous membranes. Ulcerated lesions are susceptible to secondary contamination that may slow the healing process. OBJECTIVE This study verified the influence of no...

One direct microbial parameter (germ identification in cultures) and four indirect clinical parameters (secretion, pain, burning sensation, pruritus) were analysed.

Positive detection of germs in the ulcer border and “pain” and “pruritus” revealed no influence on wound closure.
