Background: Shigella is among the most important human pathogenic microorganisms, infecting both humans and nonhuman and causing clinically severe diarrhea. Shigella must be enriched before detection, which is time-consuming.Objectives: To develop a sensitive, rapid, and specifc method for Shigella detection.Materials and Methods: S...

The claR of Streptomyces clavuligerus in the clavulanic acid gene cluster encodes a transcriptional regulator that controls clavulanic acid biosynthesis. The main goal of this study was isolation and molecular detection of the claR gene and its cloning in the Streptomyces specific vector (pMA:: hyg). By cinsideration of the claR gene’s start codon, the specific primers were designed. After geno...

Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) can cause serious and life-threatening hospital- and community-acquired infections. Colonized and infected patients represent the most important reservoir of MRSA in health care facilities. Therefore, in this study, MRSA isolates collected from Shohada Hospital in Tabriz were evaluated for the frequency of mecA gene and their anti...

Background: Weissellicin 110 is the only bacteriocin reported in Weissella cibaria up to now. This bacteriocin represents several unique features. This is the first report on the gene sequence that encodes for the bacteriocin. Objectives: Providing a rapid detection method to isolate the weissellicin 110 encoding gene and determination of the bacteriocin distribution were the objectives. Materi...

a 25-year-old female presented to the infertility opd with complaints of secondary infertility and pain lower abdomen with watery discharge for the past five days. she had history of undergoing hysterosalpingography in a private hospital ten days back. the interventions included drainage of pyometra, endometrial biopsy for routine and afb smear/ culture,  confirmation of diagnosis by m rna-base...

nosocomial infection caused by methicillin-resistant staphylococci poses a serious problem in many countries. the aim of this study was to rapidly and reliably detect methicillin-resistant-staphylococci in order to suggest appropriate therapy. the presence or absence of the methicillin-resistance gene in 115 clinical isolates of staphylococcus aureus and 50 isolates of coagulase negative staphy...

Newcastle disease is one of the main concerns of poultry farmers. Detection of virulent strains of Newcastle disease virus (NDV) has a great impact on control measures against the disease. In this study RT-PCR was optimized in high sensitivity in order to differentiate the virulent from non-virulent NDV isolates directly in tissue homogenates. The vaccinal NDV strain and known field isolates we...

A highly sensitive one-step multiplex RT-PCR (OMRT-PCR) system with an internal plant gene control was developed to simultaneously detect single and mixed RNA DNA viral pathogens affecting watermelon squash in the Southeastern United States. Current methods rely on a singleplex detection for several viruses which is time-consuming large-scale field monitoring. The gene-specific primers one viru...

background: the ability to sensitively detect vibrio cholera with pcr-elisa method represents a considerable advancement over alternative more time-consuming methods for detection of this pathogen. the aim of this research is to evaluate the suitability of a pcr-enzyme-linked immunosorbent assay for sensitive and rapid detection of v. cholera o1. methods: the 398-bp sequence of a gene that code...
