Multiplex quantification of Escherichia coli, Salmonella typhi and Vibrio cholera with three DNA targets in single reaction assay

Escherichia coli (E. coli), Salmonella typhi and Vibrio cholera harmful pathogens, which causes various diseases in humans. Rapid diagnosis of bacterial infection is an important for patient management and appropriate therapy during the early phase of the bacterial infected diseases. Among the existing techniques for identifying pathogens were less sensitive and time-consuming processes. In the present study total, 48 clinical 31 blood and 17 urine samples of patients suspected with the infections were collected from SVRR Hospital and used to detect the pathogens. Multiplex polymerase chain reaction (PCR) assay was set to design for the identification of Escherichia coli, Salmonella typhi and Vibrio cholera from the different clinical samples. Rapid diagnosis of Escherichia coli (E. coli), Salmonella and Vibrio cholera pathogens can be done with simultaneously in a single multiplex PCR assay by using specific primers with adjusted PCR conditions. Through this approach, the results represented with out of 31 blood samples 1-15 shows the positive with E. coli and remaining 14 only 11 were correlated with multiplex results of Vibrio cholera, remaining the urine samples all are positive with 17 samples correlate with the Salmonella typhi. Through the high specificity benefits of excellent sensitivity, with high resolution and reproducibility. This method of results proved and illustrates the best potential system for diagnosing the infectious disease with modern trendy.
