Interleukin-8 Receptor 2 (IL-8R2)-Deficient Mice Are More Resistant to Pulmonary Coccidioidomycosis than Control Mice.

Infect Immun 2020 Dec 15;89(1). Epub 2020 Dec 15.

Department of Medicine, Division of Infectious Disease, U.C. San Diego School of Medicine, La Jolla, California, USA

The pathology of human coccidioidomycosis is granulomatous inflammation with many neutrophils surrounding ruptured spherules, but the chemotactic pathways that draw neutrophils into the infected tissues are not known. We previously showed that formalin-killed spherules (FKS) stimulate mouse macrophages to secret macrophage inflammatory protein 2 (MIP-2), which suggested that CXC ELR+ chemokines might be involved in neutrophil recruitment To test that hypothesis, we intranasally infected interleukin-8R2 (IL-8R2) ()-deficient mice on a BALB/c background with RS. IL-8R2-deficient mice had fewer neutrophils in infected lungs than controls, but unexpectedly the IL-8R2-deficient mice had fewer organisms in their lungs than the control mice. Read More

Endemic Fungi Presenting as Community-Acquired Pneumonia: A Review.

Semin Respir Crit Care Med 2020 Aug 6;41(4):522-537. Epub 2020 Jul 6.

Indiana University, School of Medicine, Pulmonary Critical Care Medicine, Thoracic Transplantation Program, Indianapolis, Indiana.

In endemic areas, dimorphic fungal infections due to , and account for up to 30% of cases of community-acquired pneumonia. Because respiratory manifestations are often indistinguishable from common bacterial causes of pneumonia, the diagnosis of pulmonary histoplasmosis, blastomycosis, and coccidioidomycosis is often delayed and associated with antibiotics overuse. In addition to being highly endemic to certain regions of North America, dimorphic fungi have global significance due to established areas of endemicity in all six inhabited continents, an increasingly interconnected world of travelers and transported goods, and a changing epidemiology as a result of global heating and anthropomorphic land utilization.
