Establishment of loop-mediated isothermal amplification for rapid detection of .

is one of the three most pathogenic bacteria that frequently cause life-threatening opportunistic human infections, pneumonia, and lower respiratory tract infections in immunocompromised hosts, particularly in the burns ward. The present study aimed to establish a loop-mediated isothermal amplification (LAMP) method for the rapid and sensitive detection of -specific gene (GenBank ID: 882161). The gene was obtained through local and online BLAST, and specific primers were designed for this gene. Reaction conditions were optimized at 65°C for 30 min and 80°C for 2 min, whereas the reaction system contained 5.2 mM Mg, 8 U Bst 2.0 DNA polymerase, 1.4 mM deoxyribonucleotide and 0.2 and 1.6 µM of the outer and inner primers, respectively. The LAMP method was evaluated using 150 and 170 non- strains. Positive reactions were observed on 150 strains, whereas all non- strains exhibited negative results. Plasmids with the specific gene and mouse blood with were used for sensitivity assay. The detection limit of LAMP was 1 bacterium/reaction. Results indicated that the LAMP method targeted to is a fast, specific, sensitive, inexpensive and suitable method for detection of .
