Sacbrood Sacbrood virus (SBV), or Morator aetatulas, is an infectious virus affecting honeybee larvae in many areas of the world. Larvae die off before fully transforming into pupae, leaving a distinct sac-like appearance in the affected brood. The infection typically presents in the colony growth phase often in the spring. Once SBV infiltrates honeybee larvae, the larvae fail to pupate and ultimately die off. While sacbrood is often only a minor issue, this affliction causes significant damage within a colony if it is stressed or weak. Infection can lead to large areas of affected comb where the queen will refuse to lay more eggs. Additionally, infected adult bees will also have a shorter overall lifespan. As a result, the overall strength and function of a colony is compromised. Beekeepers should look for symptoms of sacbrood virus such as an uneven brood pattern with discoloured, sunken or perforated cappings. Infected larvae change from a healthy pearly white, to yellowish, then grey-brown and finally dark brown-black. Darkening begins at the head of the dead larva and spreads to the rest of the body. The skin of the dead larva also changes into a tough plastic-like sac, which is filled with fluid. The larva dies with its head characteristically raised in a banana shape toward the top of the cell and stretched out on its back in the cell. Nurse bees usually uncap the cell exposing the dead larvae. SBV infecting Chinese honeybee was named Chinese sacbrood virus (CSBV). CSBV was first described in Guangdong China in 1972 and reemerged in Liaoning China in 2008, which caused lethal disease in individual bees or the collapse of entire colonies. Chinese Sacbrood virus (CSBV) is a positive-stranded RNAvirus that infects both the European honey bee (Apis mellifera) and the Asian honey bee (A. cerana). However, CSBV has much more devastating effects on Asian honey bees than on European honey bees, posing a serious threat to the agricultural and natural ecosystems that rely on A. cerana for pollination service.
LiliF™ CSBV RT-PCR Kit is able to detect directly and specifically Chinese Sacbrood virus by CLP™ technology and Maxime ™ technology on the basis of a genetic database of target nucleic acid fragments. Therefore, this kit can diagnose very sensitive, fast and accurately. The kit contains a specific primer set for a highly conserved region based on current sequence alignments of Chinese Sacbrood virus, allowing the RNA detection. It can determine the infecting all serotype and accurately and sensitivity detect multiple detection genes at one time using the conventional RT-PCR method, and take only 2 hours for detection. Fast and sensitive detection of pathogen enables patients to get appropriate treatment and prevent the rapid spreading of disease by separating patients immediately.
• This product is a qualitative RT-PCR testing product with CLP™ technology which provided flexibility in Tm (melting temperature) of primer design for optimization of reaction condition, and maximizes RT-PCR specificity and sensitivity through the control of non-specific priming.
• The assay is a RT-PCR that discriminates Chinese Sacbrood virus in one reaction. The assay is composed of two principal steps: (1) nucleic acid extraction from specimens, and (2) amplification of the target extracted nucleic acid fragment using specific primers pair.
• This kit is developed, designed, and sold for RUO(Research Use only) purpose.
• This product is research reagent of infectious disease for professional use to restrict the public use for animal diseases.
