1 Scope

GB/T 14926.24-2026 is the Chinese national standard covering detecting pneumonia virus of mice. PVM usually causes nothing visible but alters the lungs and the immune response, which ruins respiratory and immunological work done on the colony. The method fixes the sampling, the detection technique and its controls, and the interpretation. It replaces GB/T 14926.24-2001, one of the parts of GB/T 14926 revised together in this batch. It was issued on 28 January 2026 and has been in force since 1 May 2026, replacing GB/T 14926.24-2001. The document is under the responsibility of the Ministry of Science and Technology. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document describes a method for detecting mouse pneumonia virus (PVM). This document applies to mouse pneumonia virus (PVM) in mice, rats, hamsters, guinea pigs, as well as in vitro inoculum and environmental samples from laboratory animals. The detection.

3 Terms and Definitions

This document does not contain any terms or definitions that need to be defined.

4 Principles

4.1 Antibody Detection Principle Based on immunological principles, PVM antigen was used to detect PVM antibodies in the serum of mice, rats, hamsters, and guinea pigs.

4.2 Principle of Nucleic Acid Detection Based on molecular biology principles, the unique genomic nucleic acid sequence of mouse pneumonia virus can be amplified using nucleic acid amplification methods such as polymerase chain reaction. The technology identifies the target gene or fluorescent signal, thereby obtaining the detection target.
