Molecular Evaluation of Infection and Its Association with Tumor Necrosis Factor-α Polymorphism in Recurrent Spontaneous Abortions.

Background: The rate of infections in the intensive care units (ICUs) is rising, mainly because of the increasing use of invasive procedures. Several bacterial infections and host genetic backgrounds, including TNFα SNP polymorphisms, play important roles in recurrent spontaneous abortions (RSA). So, this study aimed to evaluate C.

Variability in gene cassette patterns of class 1 and 2 integrons associated with multi drug resistance patterns in Staphylococcus aureus clinical isolates in Tehran-Iran.

Background: To investigate antibiotic resistance, the occurrence and distribution of class 1 and 2 integrons in multidrug- resistant Staphylococcus aureus isolates from hospitals in Tehran, Iran. The isolates were examined for susceptibility to antimicrobial agents. The mecA gene, class 1 and 2 integrons were detected by PCR.
