Instead of the standard SN/T 1682-2005 "European bee larvae rancid disease diagnosis." This revised standard adopts the OIE "terrestrial animal diagnostic tests and vaccines Handbook" (2010 edition) in section 2.2.3.B diagnostic techniques Content, covering microscopy, culture methods and polymerase chain reaction. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted. Jilin People's Republic of China Exit Inspection and Quarantine, Beijing People's Republic of China Entry-Exit Inspection and Quarantine Bureau. The main drafters of this standard.

This standard replaces the standards previously issued as follows. --- SN/T 1682-2005. European bee larvae rancid disease quarantine Technical Specifications1 ScopeThis standard specifies the method for the diagnosis of European bee larvae rancid disease. This standard applies to the European honeybee larvae rancid diagnosis.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. Laboratory use specifications and test methods GB/T 6682 Analysis GB/T 18088 Entry and Exit Animal Quarantine sampling3 diagnostic principlesEuropean bee larvae rancid disease (Europeanfoulbroodofhoneybees) is a hive of bees cocci (Melissococcuspluto- nius) caused the death of bee larvae a bacterial sexually transmitted diseases, the rapid growth of the colony when multiple, the most common symptoms are obvious bee larvae In the nest room closure shortly before death. Most of the larvae died of illness at the bottom of the nest room curled deformed larvae will soon be many sick care workers Bee found, remove, leaving the house empty nest. Worker bees are not infected larvae died shortly cleared softened by pale yellow becoming brown, melted into half Liquid mass, then dry, forming a dark flake easily removed from the nest room. There is a serious infection of the larvae sour smell. Cause honey Death bee larvae there are other diseases and causes of the field based on clinical symptoms and therefore can not make a reliable diagnosis. When suspected based on clinical symptoms of the disease in Europe when the larvae rancid, it is desirable to illness or death larvae smear staining, make a preliminary diagnosis Off. Under ordinary optical microscope, bee hive bacteria were single or a series or end to end in pairs or short chains arranged short lanceolate ball Bacteria, size 0.5μm × 1.0μm. The exact diagnosis requires bacterial isolation and culture and staining identification, or semi-nested polymerase Chain reaction method (polymerasechainreaction, PCR) of isolated cultures were identified. Also can be directly used semi-nested PCR Illness or death of the larvae to be confirmed. This standard is used in semi-nested PCR, a pair of primers was designed according to the bee hive bacteria 16SrRNA gene (MP1 and The MP2), for the first cycle of PCR amplification, the amplified fragment is 486bp (see Appendix A). The amplified gene as a template to design primers Article (MP3), and MP1 to MP3 as second PCR primers, amplification fragments of 276bp. 4 equipment, materials and reagents 4.1 Device Electrophoresis, gel imaging analysis system, high-speed desktop refrigerated centrifuge (maximum speed 12000r/min or more), PCR amplification, general Through an optical microscope, CO2 incubator and the like. 4.2 Materials and Reagents The method of reagent preparation see Appendix B, the water is a water according to GB/T 6682 regulations. The reagents used primarily for DNA extraction Buffer, of CTAB precipitating solution, 1.2mol L sodium chloride solution/chloroform, isopropanol, 70% ethanol, TaqDNA polymerase, 10 × ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 1682-2020_English be delivered?Answer: Upon your order, we will start to translate SN/T 1682-2020_English as soon as possible, and keep you informed of the progress.
