- Cutaneous Infection with Alternaria triticina in a Bilateral Lung Transplant Recipient.
- González-Vela MC1, Armesto S2, Unda-Villafuerte F3, Val-Bernal JF4.Author information 1Departamento de Anatomía Patológica, Hospital Universitario Marqués de Valdecilla, Universidad de Cantabria e IFIMAV, Santander, Spain.2Servicio de Dermatología, Hospital Universitario Marqués de Valdecilla, Universidad de Cantabria, Santander, Spain.3Servicio de Microbiología, Hospital Universitario Marqués de Valdecilla, Santander, Spain.4Departamento de Anatomía Patológica, Hospital Universitario Marqués de Valdecilla, Universidad de Cantabria e IFIMAV, Santander, Spain. Electronic address: apavbj@humv.es.AbstractWe report the case of a 60-year-old man who was receiving immunosuppressive therapy for a bilateral lung transplant and presented with a crusted, violaceous plaque on the left hand. Based on histopathology and microbiological culture the patient was diagnosed with infection by Alternaria species. Treatment with itraconazole led to complete resolution of the skin lesion. Forty months later he developed four reddish, nodular, skin lesions on the left leg. Analysis of a biopsy from one of these lesions using histopathologic and molecular techniques identified a mold that shared 98% homology with a strain of Alternaria triticina. Alternaria species belong to a group of dematiaceous fungi that cause opportunistic infections in humans. The incidence of these infections is increasing, mainly in transplant centers. To the best of our knowledge, this is the first reported case of a human infection caused by A. triticina.

- Crossover fungal pathogens: the biology and pathogenesis of fungi capable of crossing kingdoms to infect plants and humans.
- Gauthier GM, Keller NP.Author information University of Wisconsin - Madison, Madison, WI, USA. Electronic address: gmg@medicine.wisc.edu.AbstractThe outbreak of fungal meningitis associated with contaminated methylprednisolone acetate has thrust the importance of fungal infections into the public consciousness. The predominant pathogen isolated from clinical specimens, Exserohilum rostratum (teleomorph: Setosphaeria rostrata), is a dematiaceous fungus that infects grasses and rarely humans. This outbreak highlights the potential for fungal pathogens to infect both plants and humans. Most crossover or trans-kingdom pathogens are soil saprophytes and include fungi in Ascomycota and Mucormycotina phyla. To establish infection, crossover fungi must overcome disparate, host-specific barriers, including protective surfaces (e.g. cuticle, skin), elevated temperature, and immune defenses. This review illuminates the underlying mechanisms used by crossover fungi to cause infection in plants and mammals, and highlights critical events that lead to human infection by these pathogens. Several genes including veA, laeA, and hapX are important in regulating biological processes in fungi important for both invasive plant and animal infections.

- Phialophora verrucosa as a Cause of Deep Infection Following Total Knee Arthroplasty.
- Hochfelder J, Fetto J.Author information Department of Orthopaedic Surgery, NYU Hospital for Joint Diseases, New York, NY. Jason.hochfelder@gmail.com.AbstractDeep joint infection is one of the most feared complications following total joint replacement. Prompt diagnosis and treatment with 2-staged revision is currently the gold standard for treatment. We report a case of a chronic infection following total knee replacement caused by Phialophora verrucosa, a form of dematiaceous fungus. The patient was treated with an antibiotic spacer and a course of oral anti-fungal agents. To our knowledge, there have been no reported cases of P verrucosa as a cause of infection in hip or knee arthroplasty.
