Abstract
The results of the research showed the isolation and diagnosis of seven pathogenic bacterial species, (Staphylococcus aureus, Staphylococcus haemolyticus, Kocuria kristinae, Escherichia coli, Pseudomonas aeruginosa, Klepsella pneumonia, and Proteus mirabilis) from the patients referred to the dermatological consultation clinics at (Al-Salam Teaching hospital, General Mosul hospital and Ibn Sina Teaching hospital) in the city of Mosul in Iraq, and isolates were diagnosed based on morphological examinations, biochemical tests and confirmation by VITIC2 tests.
(110) samples were collected from different locations of the skin, (100) samples showed bacterial growth, i.e. a rate of (90.9%). These samples included (160) bacterial isolates, of which seven different bacterial types were identified, including (63) of Staphylococcus aureus, i.e. a percentage of (39.37%), (28) isolates of E. coli bacteria (17.5%), (22) isolates of P.aeruginosa bacteria (13.75%), (15) isolates from K.pneumonia bacteria (9.37%), (13) isolates of K.kristinae bacteria (8.12%), (12) isolates of S. haemolyticus bacteria (7%), and (7) isolates of P.mirabilis bacteria which represent (4.37%).
Also, sensitivity tests against conventional antibiotics were conducted using (15) types of antibiotics; the isolated species of bacteria showed “disparate” effects towards these antibiotics, and the inhibitory activity of three types of local honey were investigated (Sidr honey, mountain honey and sealed honey) with three concentrations for each type (25, 50,100) %. The results showed the high activity of the three types of honey against the studied species of bacteria; concentration of (100%) of all the three types of honey showed high activity against all the studied species of bacteria, the concentration of (50%) showed activity against all the studied bacterial species, except for mountain honey against S.aureus, and the sealed honey against K.kristinae, as they did not show inhibitory activity at this concentration, while the concentration of (25%) showed inhibitory activity on some bacterial species and did not show efficacy on others.
