Mayaro and Una Viruses Now Available

Mayaro virus (MAYV) is a New World alphavirus and the etiologic agent of Mayaro fever, an acute febrile illness sometimes accompanied by severe and persistent arthritis similar to Chikungunya fever. Its transmission cycle occurs mainly through mosquito vectors, especially those of the genus Haemagogus, but Aedes spp. mosquitoes may also be competent vectors. The enzootic transmission cycle of MAYV is not fully understood, but the occurrence of relatively large outbreaks of Mayaro fever and the competence of Aedes mosquitoes for the transmission of MAYV suggest the potential for an urban human-mosquito-human transmission cycle to emerge. MAYV was first isolated in ...more

Yellow Fever Virus Reagents

Yellow fever is an acute viral hemorrhagic, mosquito-borne disease that is endemic in many regions of Africa and South America. Yellow fever can be prevented through vaccination; however, recent vaccine shortages have resulted in alarming outbreaks of the disease in endemic regions. To help control outbreaks, prompt detection of the disease is essential. Regrettably, yellow fever is difficult to diagnose (particularly during the early stages) as the associated symptoms can be confused with malaria, leptospirosis, viral hepatitis (especially fulminant forms), or other hemorrhagic fevers such as dengue hemorrhagic fever. To aid researchers studying yellow fever, BEI Resources now provides Yellow fever virus (YFV) strain SVM 3-18-09 (NR-49799), which is wild-type strain isolated from a monkey (Alouatta sp.) in Maracas, Trinidad in 2009.

GFP- and luciferase-expressing Toxoplasma gondii

To aid toxoplasmosis research, BEI Resources houses a dual expressing GFP/luciferase (FLUC) T. gondii transgenic strain. T. gondii Pru A7 ∆hxgprt::gra2-GFP::tub1-FLUC (NR-49335) was engineered via transfection of the Pru ∆hxgprt strain with a plasmid expressing GFP and FLUC under the control of the GRA2 and TUB1 promoters, respectively. This results in the constitutive expression of GFP and FLUC in both the tachyzoite and bradyzoite infective stages. NR-49335 has been used to study bioluminescence imaging of T. gondii dissemination in mice and the role of bradyzoite-specific antigens in establishing chronic infections.

Zika virus peptide arrays

Peptide arrays for nonstructural protein 1 (NS1) and the envelope (E) protein of Zika virus strain PRVABC59 are now available from BEI Resources. NR-50534 is a 114-peptide array spanning NS1 (GenPept: AMZ03556), NR-50553 is a 164-peptide array that spans the E protein (GenPept: AMZ03556), and NR-50554 is a 5-peptide array that represents a region of amino acid sequence diversity in the E protein. A peptide array covering the entire E protein of the CDC sequence (GenPept: AMC13911) can be constructed using NR-50554 and NR-50553.

Three New Sand Fly Species

BEI Resources also announces the availability of 3 additional species of sand fly vectors through WRAIR, including: Phleobotomus duboscqi strain Mali, Phleobotomus sergenti strain South Sinai, Egypt and Phleobotomus arabicus strain Israel

Sand Flies, Reduviids and Ticks Available

The Vector Resource materials within BEI Resources aims to support research to discover new ways to prevent the spread of disease. Vectors—organisms that transmit pathogens to hosts—include mosquitoes, ticks, triatomine bugs, sand flies, black flies, tsetse flies, fleas, mites and certain freshwater snails. BEI Resources currently supplies mosquitoes, ticks, reduviids, sand flies and snails to researchers.
