Introduction
Introduction
GB/T 35904—2018 "Real-time fluorescence PCR detection method for Trichinella spiralis" is an important standard formulated by the Ministry of Agriculture of China, which aims to standardize the nucleic acid detection process of Trichinella spiralis. This article will deeply analyze the core content of the standard and interpret it with actual cases.
Standard background and technical evolution
Trichinella spiralis infection is a serious public health problem worldwide, especially in meat quarantine. Real-time fluorescence PCR technology has become the preferred method for detecting Trichinella spiralis with its high sensitivity and specificity. This standard is based on internationally leading technology to ensure the reliability of the test results.
Instruments and reagents
According to the standard requirements, the fluorescence PCR instrument is the core equipment, and it is matched with auxiliary instruments such as high-speed refrigerated centrifuge and biological safety cabinet. In terms of reagents, high-purity PCR buffer, dNTP and probes are used to ensure detection accuracy.
Comparison table of standard frameworks
| Standard dimensions | GB/T 35904—2018 | Differences in international standards |
|---|---|---|
| Detection objects | Trichinella nucleic acid | Consistent with ISO standards |
| Reagent requirements | High-purity biological reagents | Higher than the standards of some countries |
| Operation process | PCR amplification + fluorescence detection | Optimized cycling conditions |
Actual application cases
In a pig farm, this standard method was used to test a batch of pigs for Trichinella spiralis. The results showed that the Ct value was 28, which was judged to be positive. This helped the farm to isolate the infected pigs in time and avoid the spread of the epidemic.
Implementation Recommendations
In order to ensure the effective implementation of the standard, it is recommended that:
- Laboratories should be equipped with advanced PCR equipment
- Operators should receive regular professional training
- Establish a complete quality control system
