Clinical samples were analyzed using standard bacteriological and parasitological methods. One hundred seventy three patients were subjected to this study and leishmania was found in 84 (48.5%) cases. According to bacteriological experiments, 47 cases (55.9%) had been also infected by bacterial infections. The most prevalent bacterial isolates included group D Streptococcus (19.1%), Enterococcus spp. (19.1%) and Staphylococcus aureus (12.7%).
