Surveys reveal a complex association of phytoplasmas and viruses with the blueberry stunt disease on Canadian blueberry farms
Surveys for phytoplasmas and viruses were conducted during September 2014 and 2015 on highbush blueberry farms in the Région Montérégie, Quebec. Total DNA and RNA were extracted from blueberry bushes showing blueberry stunt (BBS) symptoms and from symptomless blueberry bushes, and utilised as templates for PCR and RT‐PCR assays, respectively. Phytoplasma DNA was amplified with […]
Molecular and biological characterization of phytoplasmas from coconut palms affected by the lethal yellowing disease in Africa.
Côte d’Ivoire lethal yellowing (CILY) is a devastating disease associated with phytoplasmas and has recently rapidly spread to several coconut-growing areas in the Country. Phytoplasmas are phloem-restricted bacteria that affect plant species worldwide. These bacteria are transmitted by plant sap-feeding insects, and their cultivation was recently achieved in complex artificial media. In this study, phytoplasmas […]
USP 62 – Microbiological examination of non-sterile products: Tests for specified microorganisms [USP62]
This is a product safety test specified by the United States Pharmacopeia Convention (USP) to evaluate the presence or absence of specified microorganisms. These tests are necessary for cosmetic and personal care products especially products that have high potential for use around the eyes, nose and mouth. Passage of these bioload challenges is required prior […]
USP 61 – Microbial examination of non-sterile products: Microbial enumeration tests [USP61]
This is a product safety assessment designed to evaluate the microbial content of non-sterile products such as pharmaceuticals products, cosmetics and personal care. These tests can be performed on finished products, raw materials or environmental swabs. The USP 61 assessment contains two tests, microbial enumeration and a suitability test: 1. Microbial enumeration The microbial enumeration […]
