The present study evaluated rickettsial infection in Amblyomma spp. ticks collected in a farm in Coronel Pacheco, a Brazilian spotted fever (BSF) endemic area. [scielo.br]

It presents high mortality rates in Brazil, with transmission to humans or animals through the bite of infected ticks. [uel.br]

• Respiratory Distress

  We report a probable case of atypical fulminant Brazilian spotted fever that presented full-blown septic shock associated with Adult Respiratory Distress Syndrome (ARDS) and delayed uncharacteristic rash with an over four-fold increase in reciprocal IgM [ncbi.nlm.nih.gov]

  The patient was transferred to the intensive care unit where a new chest x ray showed extensive bilateral alveolointerstitial infiltrate (Figure 1-A), compatible with Adult Respiratory Distress Syndrome (ARDS). [scielo.br]

• Leptospira Interrogans

  Abstract Five serovars of Leptospira interrogans, Leptospira biflexa, Leptonema illini, and Rickettsia rickettsii were examined and found not to contain the 39-kDa antigen (P39) of Borrelia burgdorferi, the Lyme disease spirochete. [ncbi.nlm.nih.gov]

• Bartonella Henselae

  We describe a serosurvey for Rickettsia rickettsii, R. typhi, Coxiella burnetii, Bartonella henselae, B. quintana, and Ehrlichia chaffeensis in 437 healthy people from a Brazilian rural community. [ncbi.nlm.nih.gov]

• Lymphocytic Infiltrate

  RR was easily visualized within cytoplasm and nuclei of endothelial cells in association with perivascular lymphocytic infiltrates and less frequently with vasculitis or non-inflamed vasculature. [ncbi.nlm.nih.gov]

However, under all treatment conditions, a significant number of rickettsiae could be detected microscopically. [ncbi.nlm.nih.gov]
