Concurrent Dengue-Malaria Infection: The Importance of Acute Febrile Illness in Endemic Zones.

Context: Acute febrile disease (AFI) in endemic tropical areas is a frequent reason for consulting the emergency services. Infection by 2 or more etiological agents may modify clinical and laboratory parameters, making diagnosis and treatment a challenge.

Case Report: We report the case of a patient who came from Africa and consults in Colombia, with AFI with thrombocytopenia that was eventually diagnosed to have concurrent infection with malaria and dengue.

Systemic protothecosis in an immunocompetent patient.

Background: Although uncommon, there is increasing interest and public health concerns of the pathogen Prototheca spp, a ubiquitous achlorophilic microalgae that can affect both humans and animals. High mortality rates have been reported in immunocompromised patients with disseminated infection, but no data is available in the immunocompetent population.

Case Presentation: We present the case of a 59-year-old man from rural area of Colombia who was admitted to the intensive care unit due to decompensated heart failure that was difficult to medically manage, with development of septic shock and isolation of Prototheca wickerhamii from blood culture.
