Selective detection of Mycoplasma fermentans by polymerase chain reaction and by using a nucleotide sequence within the insertion sequence-like element

Detection of Mycoplasma pneumoniae by using the polymerase chain reaction.

The polymerase chain reaction (PCR) technique was used to detect Mycoplasma pneumoniae. A specific DNA sequence for M. pneumoniae was selected from a genomic library, and two oligonucleotides were chosen in this sequence to give an amplified fragment of 144 base pairs. We show that DNA from different M. pneumoniae strains can be detected by PCR, with DNA from other Mycoplasma species giving neg...

Rapid Detection of Campylobacter jejuni by Polymerase Chain Reaction and Evaluation of its Sensitivity and Specificity

Introduction: Campylobacter jejuni is one of the most common causes of food poising in humans. Rapid and specific detection of these bacteria has an important role in diagnosis and treatment of infection. The aim of this study was to design a specific PCR for the detection of Campylobacter jejuni. Methods: In this experimental study, oxidoreductase gene from the Campylobacter jejuni was sele...

Nucleotide sequence of Clostridium difficile toxin A gene fragment and detection of toxigenic strains by polymerase chain reaction.

A 1947 base pair (bp) fragment of the toxin A gene of Clostridium difficile was sequenced. A continuous open reading frame was found, which contained 4 distinct groups of repeat nucleotide sequence with 88 to 100% identity within each group. The arrangement of the groups (A, 81 bp, B, C and D, 63 bp) was ABCCCDABCDDABCCCDABCCDABCDABC. Based on nucleotide sequence data from the C repeat group, a...

Polymerase Chain Reaction of Mgc2 and 16S rRNA Genes for Detection of Mycoplasma gallisepticum

Mycoplasmas are very small bacteria lacking cell walls that belong to various genera within the class Mollicutes, and also the smallest organisms that can live independently. They are able to cause serious and chronic disease because of some unique characteristics. Mycoplasma gallisepticum (MG) is an important avian pathogen causing significant economical losses within the poultry industry. The...
