Resistance pattern of Escherichia coli to levofloxacin in Iran: a narrative review.
Authors: Hassanshahi G, Darehkordi A, Fathollahi MS, Falahati-Pour SK, Zarandi ER, Assar S Abstract Fluoroquinolones (FQs) are widely used in the treatment of infections caused by Escherichia coli. FQs are broad spectrum antibiotics with high tissue penetration, and ease of use. Therefore, given the concerns existing about drug resistance, we aim to review the latest findings about resistance patterns to levofloxacin (LVX) along with other FQs in E. coli infections in different parts of Iran. Evidence shows that quinolones have been used in Iran for nearly 50 years, and that 0-65% of E. coli isolates show resistanc...

People from all walks of life are badly affected because of compulsory lockdown around the world. Timely diagnosis is a problem as there is no single test that can achieve the highest acceptable sensitivity. Some of the tests are indeed costly and footing the bill by the governments can cause a tremendous load on the Treasury. As it stands, the current tests are beyond patient means and, thus, the patient would never have it performed. Lastly, there is no consensus as to whether everyone should be tested...

Comparative evaluation of hydrogen peroxide sporicidal efficacy by different standard test methods.
Conclusion: The results of this study showed that it is reasonable to use interfering substances and inoculated carriers in accordance with actual conditions of product usage in a sporicidal test. Interfering substances may reduce the contact surface between H2O2 and test spores; therefore, the sporicidal efficacy of H2O2 was diminished. So applying suspension test in clean condition to verify the claim of sporicidal activity is strongly discouraged. PMID: 32494345 [PubMed] (Source: Iranian Journal of Microbiology)
