Abstract

The invention discloses a method for detecting bartonella elizabethae with TaqMan real-time fluorescent quantitative PCR. The method selects a Be specific gene sequence and obtains specific primers (SEQ ID No.2 and SEQ ID No.3) and a TaqMan probe (SEQ ID No.4) based on the specific gene sequence design. The method can detect the bartonella elizabethae under species level specificity and high sensitivity and provides effective means for researches such as early and rapid diagnosis and monitoring of a series of diseases caused by the bartonella and epidemiological investigation.

Description

technical field

[0001] The invention belongs to the field of molecular biology detection, in particular to a TaqMan real-time fluorescent quantitative PCR detection method for Bartonella Elizabeth. Background technique

[0002] Bartonella elizabethae (Be) is a Gram-negative bacillus that can cause Bartonella elizabethae endocarditis. In 1993, Daly et al. isolated from the blood of a patient with endocarditis in the Elizabeth Hospital in the United States. It is a newly discovered zoonotic pathogen in the genus Bartonella.

[0003] Bartonella Elizabeth has the common characteristics of Bartonella genus bacteria, which requires high culture conditions and long culture time. At present, the detection methods of this bacteria at home and abroad are mainly isolation culture and conventional PCR detection of nucleic acid molecules. Although the isolation and culture method can obtain direct evidence of infection, it is not suitable for rapid diagnosis, screening and epidemiologi...
