    Endemic Scrub Typhus-like Illness, Chile
    (Centers for Disease Control an Prevention, 2011) Balcells Marty, María Elvira; Rabagliati Borie, Ricardo Miguel; García Cañete, Patricia Del Carmen; Poggi Mayorga, Helena Loreto; Oddo Benavides, Carlos David; Concha Rogazy, Marcela Andrea; Abarca Villaseca, Katia; Jiang, Ju; Kelly, Daryl J.; Richards, Allen L.; Fuerst, Paul A.
    We report a case of scrub typhus in a 54-year-old man who was bitten by several terrestrial leeches during a trip to Chiloe Island in southern Chile in 2006. A molecular sample, identified as related to Orientia tsutsugamushi based on the sequence of the 16S rRNA gene, was obtained from a biopsy specimen of the eschar on the patient's leg. Serologic analysis showed immunoglobulin G conversion against O. tsutsugamushi whole cell antigen. This case and its associated molecular analyses suggest that an Orientia-like agent is present in the Western Hemisphere that can produce scrub typhus-like illness. The molecular analysis suggests that the infectious agent is closely related, although not identical, to members of the Orientia sp. from Asia.

    The confrontation of the differential and etiological diagnosis of the infectious diseases of cancer patients, including hematopoietic stem cells transplant (HSCT) recipients, must correspond to an informed, timely decision that directly affects medical behavior that determines a better survival and quality of life for patients. The main goal of this work was to contribute to the management of these patients developing a useful tool for the clinician to make these decisions. For that, infections were grouped by compromised systems, differentiating the possible etiological agents in bacteria, viruses, fungi and parasites, highlighting the relevant diagnostic tests, mentioning the recommended techniques together with the optimal sample type for proper processing. In addition, under each group of techniques we added the item "level of requirement" to suggest what, in the opinion of the authors and the existing evidence, must be mandatory to have at local level or can be derivable to another laboratory.
