Agranulocytosis and Aseptic Meningitis Induced by Sulfamethoxazole-Trimethoprim.

Background: Sulfamethoxazole-trimethoprim is an antibiotic that can cause rare and potentially life-threatening adverse effects. This case describes an immunocompetent patient who developed acute agranulocytosis complicated with aseptic meningitis after being prescribed sulfamethoxazole-trimethoprim.

Case Presentation: A healthy 39-year-old male veteran presented to the emergency department with worsening left testicular pain and increased urinary urgency and frequency.

Taxonomic shifts in arbuscular mycorrhizal fungal communities with shade and soil nitrogen across conventionally managed and organic coffee agroecosystems.

The composition of arbuscular mycorrhizal fungal (AMF) communities should reflect not only responses to host and soil environments, but also differences in functional roles and costs vs. benefits among arbuscular mycorrhizal fungi. The coffee agroecosystem allows exploration of the effects of both light and soil fertility on AMF communities, because of the variation in shade and soil nutrients farmers generate through field management.

Contrasting Patterns of Functional Diversity in Coffee Root Fungal Communities Associated with Organic and Conventionally Managed Fields.

The structure and function of fungal communities in the coffee rhizosphere are influenced by crop environment. Because coffee can be grown along a management continuum from conventional application of pesticides and fertilizers in full sun to organic management in a shaded understory, we used coffee fields to hold host constant while comparing rhizosphere fungal communities under markedly different environmental conditions with regard to shade and inputs. We characterized the shade and soil environment in 25 fields under conventional, organic, or transitional management in two regions of Costa Rica.
