Bacterial infections in suspected cutaneous leishmaniasis lesions.
In Iran, microscopic examination of skin scrapings from 2202 individuals with clinically diagnosed cutaneous leishmaniasis (CL) lesions revealed the presence of amastigotes in 1123 cases (51.0%). Bacteriological examinations of the lesions indicated that 788 individuals (35.7%) were also infected with one or more pathogenic bacteria, including coagulase-positive staphylococci (27.8%), beta-haemolytic streptococci (10.6%), and other opportunist pathogenic bacteria (total, 2.5%). The prevalence of bacterial infections in lesions in which leishmania parasites were detected was 26.5%, while for lesions in which no parasite was found the prevalence of such infections was significantly greater (45%). The results of this study show that bacterial infections should be considered in diagnosing and treating suspected CL lesions, particularly in areas where there is no facility for carrying out bacteriological examinations. Erythromycin can be used to treat the bacterial infections of the purulent sores.
