RESUMO
Se expone el caso de una mujer joven con diagnóstico de infección por el virus de inmunodeficiencia humana (VIH) y abandono de tratamiento antiretroviral, ingresada por cuadro febril y tos, con sospecha de tuberculosis miliar. Evoluciona durante su internación con pancitopenia y esplenomegalia, iniciándose investigación y diagnóstico precoz de síndrome hemofagocítico (SHF). Presenta evolución desfavorable y óbito debido a múltiples comorbilidades.
This is the case of a young woman who was diagnosed with a human immunodeficiency virus (HIV) infection and had stopped the antiretroviral therapy. She was admitted for fever and cough with suspicion of miliary tuberculosis. The patient evolved during her hospitalization to splenomegalic pancytopenia. An investigation started and there was an early diagnosis of hemophagocytic syndrome (HPS). The patients evolved unfavorably and died due to multiple co-morbilities.
RESUMO
This paper describes a pathological condition in intensive reared Atlantic salmon (Salmo salar), restricted to the appearance of pseudo-membranes covering internal organs (i.e. spleen, liver, heart and others) associated with the presence of large numbers of a Gram-positive bacteria. Isolate 79043-3, obtained as pure culture from affected fish, was subjected to a polyphasic taxonomic study in order to determine its exact taxonomic position, as well as to experimental challenges leading to determine its pathogenic potential for cultured fish. Based on this characterization, we report the first isolation of Rhodococcus qingshengii, from a farmed population of Atlantic salmon in Chile. Virulence studies demonstrated that the isolate fulfilled the Koch's postulates, suggesting that this bacterial species could be considered as an opportunistic pathogen for Atlantic salmon.
