The Correlation between Serum Levels of Anti-Toxoplasma gondii Antibodies and the Risk of Diabetes

Background: This study investigated the presence of specific antibodies against Toxoplasma gondii infection among people with diabetes (type I and II) in comparison with control group. Methods: Overall 300 serum samples were collected equally from three groups including patients with type I and type II diabetes and non-diabetic healthy control that referred to Tabriz Central Laboratory in northwest Iran during July to Sep 2015. The level of specific IgG and IgM antibodies against T. gondii were measured using the chemiluminescence immunoassay (CLIA) method. Chi-square and One-Way ANCOVA were used for data analysis. Results: Overall, 300 samples from diabetic patients (type I and type II) and control group were examined and results showed 3, 8 and 2 cases were seropositive for anti- T. gondii IgM respectively. Anti- T. gondii IgG seropositivity in type I and type II diabetes and control groups were 69%, 63% and 59% respectively. We did not observe any statistical differences among all studied groups in terms of toxoplasmosis. There was no statistically significant relationship between all variables and seropositivity for anti-T. gondii antibodies in type I and II diabetes and non-diabetic groups. Conclusion: Although there was no statistically significant relationship between diabetes and toxoplasmosis further investigations especially experimental studies using animal models are needed. Furthermore, these findings would not be contrary to the need for healthcare in order to the prevention of infectious disease in diabetic patients

Study of Sensibility and Antimicrobial Resistance in Escherichia coli Isolated from Urinary Tract Infection in Tabriz City

 Background & Objective: Urinary infection is one of the most prevalent infectious diseases, and Escherichia coli is the most important cause of urinary infections. This study was done with the aim of surveying the amount of susceptibility and resistance among the strains of Escherichia coli isolated from those who referred to the private laboratories in the Iranian city of Tabriz.   Materials & Methods: This survey was done periodically during the first 6 months of the year 2010. Samples were obtained in a sterile manner and were subjected to all necessary pathological tests. Evaluation of antibiotic susceptibility was conducted with disk diffusion standard method, and the results were analyzed.   Results: Totally, 5701 Escherichia coli strains were identified. The highest sensitivity to Imipenem was 90.95%, Nitrofurantoin 85.97%, and Cefotaxime 71.02% and the highest resistance to Ampicillin was 83.95%, Tetracycline 80.97%, and Co-trimoxazole 63.92%.   Conclusion: Our results suggest that the cause of the high resistance of Escherichia coli strains to Ampicillin and Tetracycline could be the consumption of these antibiotics. Therefore, abstaining from overuse of unnecessary antibiotics and production of new-generation and cost-effective antibiotics are recommend.
