Although molecular methods are available, such as polymerase chain reaction (PCR) for identifying the Bartonella species, limitations exist. One limitation to testing is the specificity of:
a. probes.
b. polymerases.
c. primers.
d. restriction enzymes.
C
PCR targeting the 16S-23S ribosomal ribonucleic acid (rRNA) gene intergenic transcribed spacer region has been proposed as a reliable method for the detection of Bartonella deoxyribonucleic acid (DNA) in clinical samples. However, a recent study revealed some potential limitations, based on insufficient primer specificity.
