Eight isolates of Phellinusweirii (Murr.) Gilb. (Poriaweirii (Murr.) Murr.), a serious pathogen of conifer roots in northwestern United States and southern British Columbia, formed sporocarps on malt agar after exposure to continuous near-ultraviolet light for 4 days at certain temperatures followed by incubation at normal laboratory temperature (22–24 °C) and lighting conditions (118 lx for 8–9 h). Isolates G7312 and T-55 formed sporocarps when cultures were placed in normal or inverted positions; other isolates produced sporocarps only in an inverted position. Effective light–temperature combinations varied among isolates. Of all isolates, only G7312 and T-55 were induced to form sporocarps by fluorescent white light.

Sound Management

The biosolids producers in southwest Canada and the northwest United States have banded together to form a biosolids information network with the purpose of advancing the environmentally sound management of biosolids through education and information, regulations development and research and demonstration. This organization currently known as the Northwest Biosolids Management Association (NBMA) has grown from a gritty band of 14 sludge management visionaries to a fully incorporated non-profit association of over 200 members in both the private and public sectors. What spark ignited this conflagration of creativity? What calamity could possibly convince 200 relatively sober agencies to pony up a collective $200,000 American every year? What great cosmic bellows continues to force the airs of inspiration into the dry and desiccated souls of Biosolids managers across beautiful British Columbia and beyond? The answers lie in the modern day alchemy that is biosolids management. It is the inspiration gained from spinning gold out of something less aesthetically pleasing. It is the satisfaction in communicating to a mass audience the technical and counter intuitive science of residuals treatment. Creation and maintenance of a Biosolids information network is an essential tool in fostering the environmentally sound use of this extremely useful product.

Abstract Objective: Our objective was to compare patterns of dental antibiotic prescribing in Australia, England, and North America (United States and British Columbia, Canada). Design: Population-level analysis of antibiotic prescription. Setting: Outpatient prescribing by dentists in 2017. Participants: Patients receiving an antibiotic dispensed by an outpatient pharmacy. Methods: Prescription-based rates adjusted by population were compared overall and by antibiotic class. Contingency tables assessed differences in the proportion of antibiotic class by country. Results: In 2017, dentists in the United States had the highest antibiotic prescribing rate per 1,000 population and Australia had the lowest rate. The penicillin class, particularly amoxicillin, was the most frequently prescribed for all countries. The second most common agents prescribed were clindamycin in the United States and British Columbia (Canada) and metronidazole in Australia and England. Broad-spectrum agents, amoxicillin-clavulanic acid, and azithromycin were the highest in Australia and the United States, respectively. Conclusion: Extreme differences exist in antibiotics prescribed by dentists in Australia, England, the United States, and British Columbia. The United States had twice the antibiotic prescription rate of Australia and the most frequently prescribed antibiotic in the US was clindamycin. Significant opportunities exist for the global dental community to update their prescribing behavior relating to second-line agents for penicillin allergic patients and to contribute to international efforts addressing antibiotic resistance. Patient safety improvements will result from optimizing dental antibiotic prescribing, especially for antibiotics associated with resistance (broad-spectrum agents) or C. difficile (clindamycin). Dental antibiotic stewardship programs are urgently needed worldwide.
