The Distribution of Indian Tick Typhus with Notes on Laboratory Findings

Rickettsial retinitis—an Indian perspective

BACKGROUND Though rickettsiosis is common in India, there is paucity of rickettsial retinitis (RR) reports from India. Moreover, rickettsial sub-types and their association with retinitis have not been studied. We are reporting a case series of presumed RR with their course of the disease, visual outcome, and association with rickettsial sub-type based on Weil-Felix test. FINDINGS This is a r...

Detection of European Strain of Echinococcus multilocularis in North America

of the Rickettsia spp. we identifi ed. As shown (2), multilocus analysis with ompA–ompB sequences was highly informative about the phylogenetic relationship between Rickettsia spp. and R. conorii strains (Figure, panel B). In Sicily, R. conorii Malish strain has been characterized in MSF patients (4), and R. slovaca DNA was identifi ed in ixodid ticks (5). However, to our knowledge, R. slovaca ...
