Problems solved by technology

Virus isolation and culture takes a long period of time, cumbersome operations, professional operators and harsh laboratory conditions are required, so it is rarely used in clinical rapid diagnosis
[0008] 2) There is still lag in immunological diagnosis, which cannot accurately reflect whether the current infection or pathogen is carried, and it is difficult to meet the requirements of early diagnosis
The high similarity between HSV-1 and HSV-2 makes it difficult to detect HSV types

Abstract

The invention relates to the technical field of detection of pathogenic microorganisms, in particular to a detection marker, primer probe pair, kit and detection method for herpesvirus hominis I typeand II type. By taking reverse repeated sequences RS1 and RS2 in an HSV genome as a target area, the detecting sensitivity can be further improved as two copies are available in the genome on the onehand and cross reactions are unlikely to be caused as the inter-nucleic acid similarity is low on the other hand.

Description

technical field [0001] The invention relates to the technical field of detection of pathogenic microorganisms, in particular to a detection marker of herpes simplex virus type I and / or type II, a pair of primers and probes, a kit and a detection method. Background technique [0002] Herpes simplex is a viral skin disease caused by herpes simplex virus, which can cause various human diseases, such as gingivostomatitis, keratoconjunctivitis, encephalitis, reproductive system infection and neonatal child's infection. [0003] Herpes simplex virus (HSV) belongs to the subfamily Avirinae of the family Herpesviridae, and the size of the virus plasmid is about 180 nanometers. According to the difference in antigenicity, the virus is currently divided into type I (HSV-1) and type II (HSV-2). HSV-1 is mainly obtained from lip lesions, and can also be isolated from genital lesions, and HSV-2 can be isolated from genital lesions. Infection is due to human-to-human contact, and it is...
