Exposure to the dye congo red has been known to cause allergic reactions (Bhattacharyya and Sharma 2004; Pavan et al. 2008).
A 2009 deployment of military units from several Saudi Arabian provinces to Jazan Province, Saudi Arabia, enabled us to evaluate exposure to Alkhurma, Crimean-Congo, dengue, and Rift Valley hemorrhagic fever viruses.
Patients 1 3 and 6 7 (Table 3) had benign WNV infections with fever, rash, myalgia, and arthralgia; specimens from patient 6 were submitted for the exclusion of viral hemorrhagic fever only because he had an outdoor occupation in Namibia with potential exposure to ticks, and thus Crimean-Congo fever was considered a possibility.
IgM antibody tests were performed on all the samples to exclude recent exposure to Ebola virus, Marburg virus, Crimean-Congo hemorrhagic fever virus, West Nile virus, dengue virus, chikungunya virus, Sindbis virus, and Rift Valley fever virus.
Therefore, ΔrsrA mutants and their wild type controls were assessed for response to a variety of challenges including exposure to hydrogen peroxide (H2O2), tert-butyl hydroperoxide (tBOOH), camptothecin, alkaline pH, sodium chloride, sorbitol and congo red.
