Diagnosis and identification of bacteria and fungi associated with psoriasis patients and assessment of their sensitivity to antibiotics

Abstract

One hundred Samples were collected from patients with skin psoriasis, from patients attending General Samarra Hospital/ Salah El-Din, during the period from September 2022 to January 2023, for ages from (2-80) years. It was found that 60 samples from the total specimen gave bacterial growth, including 20 isolates, 33.4% belonging to Staphylococcus aureus, 18 isolates, 30% Staphylococcus epidermidis, 15% Staphylococcus hominas with 9 isolates. While the percentage of isolation of Pseudomonas aeruginosa and Escherichia coli was 13.3% and 8.3%, with 8 and 5 isolates respectively. All isolated bacterial species were 100% sensitive to Vancomycin, Imipenem, Nirtofurantoin and Meropenem, while they were resistant to Ceftriaxone, Trimethoprim, Sulbactam/Ampicillin, Calvulanic acid/Amoxicillin, Azithromycin and Gentamicin. As for the antibiotic ciprofloxacin, the Gram-positive isolates were resistant to it, while the Gram-negative isolates were resistant by 50% and 60% to both P. aeruginosa and E. coli respectively. The percentage of the distribution of infection varied, so it was in the trunk and extremities were 36.6% with 30 samples, while the scalp was 26 with 31.7%, the palms of the hands was 16 samples in percentage 19.5%. The soles of the feet was 10 samples in 12.2%. As for the nature of work, the highest percentage was for farmers with a rate of 30.5% with 25 samples, and employees and self-employed people 20 samples with a rate of 24.4%. As for the student, their percentage was 20.7% with 17 samples.
