Clinical Case Reports, Volume 14, Issue 4, April 2026.ABSTRACT In endemic regions where simultaneous larval tick bites frequently occur, early identification of tick species from eschar lesions may substantially influence presymptomatic clinical triage. We report a 78‐year‐old woman who was found after approximately 24 h of wandering, presenting with multiple clustered eschars on the lower extremities and

Phylogenies of atpD and recA support the small subunit rRNA-based classification of rhizobia [PDF]
, 2001 The current classification of the rhizobia (root-nodule symbionts) assigns them to six genera. It is strongly influenced by the small subunit (16S, SSU) rRNA molecular phylogeny, but such single-gene phylogenies may not reflect the evolution of the ...

Immunoproteomic profiling of Rickettsia parkeri and Rickettsia amblyommii
Ticks and Tick-borne Diseases, 2015 Rickettsia parkeri is an Amblyomma-associated, spotted fever group Rickettsia species that causes an eschar-associated, febrile illness in multiple countries throughout the Western Hemisphere. Many other rickettsial species of known or uncertain pathogenicity have been detected in Amblyomma spp.

Rickettsia felisand Changing Paradigms about Pathogenic Rickettsiae
Emerging Infectious Diseases, 2014 To the Editor: Mediannikov et al. recently reported several features common to the epidemiology of Rickettsia felis infection and malaria in Africa (1). Similar to the findings of several other recent studies in Africa (2,3), the authors diagnosed R. felis infection in febrile—and to a lesser extent in afebrile—persons by detecting R.
