Latex-Rickettsia rickettsii test reactivity in seropositive patients [PDF]
Journal of Clinical Microbiology, 1983 In correlating results obtained from a new latex-Rickettsia rickettsii test with results obtained from a reference microimmunofluorescence test for Rocky Mountain spotted fever, we found that for seropositive patients each microimmunofluorescence titer (up to 4,096) was usually double the median titer obtained from the latex-R. rickettsii test.

Pest Management Science, Volume 82, Issue 10, Page 9653-9665, October 2026.Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.

Journal of Applied Ecology, Volume 63, Issue 10, October 2026.Policy implications. Our results can help prioritize surveillance strategies and the implementation of preventive measures, particularly in areas where landscape structures cannot provide disease regulation services. Landscape management actions aimed at increasing the amount of forest areas in a more aggregated manner could help restore those ...

Reactivity of monoclonal antibodies to Rickettsia rickettsii with spotted fever and typhus group rickettsiae [PDF]
Journal of Clinical Microbiology, 1987 Analysis of 15 spotted fever group (SFG) and 2 typhus group strains of rickettsiae with a panel of monoclonal antibodies revealed a number of shared and unique epitopes of the 120- and 155-kilodalton surface proteins. All of the SFG strains but neither of the typhus group strains reacted with antibody to the lipopolysaccharidelike antigen of Rickettsia
