Isolation and Diagnosis of Some Isolated Bacterial Types of Psoriasis Patients and Measurement of Some Immunological Parameters Such as Il-17 And Complements C3 and C4

aureus, 33.3% of the 60 bacterial isolates were isolated, it isolated 18 isolates of Staph epidermidis with 30% of the total isolates and Staphylococcus hominas isolated by 15%, gram-negative isolates included 13.3% of P. aeruginosa and five isolates of E. coli (8.3%), some immune markers were compared between a group of psoriasis patients and a healthy (control) group, the estimated C3 supplement level for patients is 265.1 ± 215.77, while the rate for healthy people is 652.18 ± 102.3, it is noted that this indicator is higher in patients with psoriasis compared to healthy people, it also indicates that the estimated C4 supplement level for patients is 392.92 ± 63.7, while the rate for healthy people is 167.94 ± 38.7. It is noted that this indicator is higher in patients with psoriasis compared to healthy people, the IL-17 level of interleukin was 765.29 ± 85.4, while the rate for healthy people is 212.37 ± 39.6. It is noted that this indicator is higher in patients with psoriasis compared to healthy people, the results also showed significant differences between the levels of immune indicators between patients and healthy people at a probability level (p value = 0.05).
