Human immunodeficiency virus type 1 isolates of envelope genotype E are contributing substantially to the global pandemic. These strains appear to be mosaics, with the gag gene from clade A and the envelope from clade E; the parental clade E strain has not been found. Here we report the first full genomic sequence of one such mosaic virus, isolate CM240(More)
Of the nine genetic subtypes of HIV-1 that exist world wide, subtype B predominates in North America and Europe. Thus, most knowledge about HIV-1 and most vaccine development efforts are based on subtype B viruses. We document here the detection of HIV-1 subtypes A, D, and E in five US servicemen who acquired these non-subtype-B infections during overseas(More)
There are nine recognised genetic subtypes of HIV-1, and the epidemic in Southeast Asia is largely due to subtype E. We have investigated HIV-1 viral subtypes in 11 Uruguayan military personnel, six with infection acquired during a United Nations deployment to Cambodia and five with infection acquired in South America. We found subtype E in five of the six(More)
As demonstrated by the recent 2012/2013 flu epidemic, the continual emergence of new viral strains highlights the need for accurate medical diagnostics in multiple community settings. If rapid, robust, and sensitive diagnostics for influenza subtyping were available, it would help identify epidemics, facilitate appropriate antiviral usage, decrease(More)
Background.  Delayed recognition of spinal epidural abscess (SEA) contributes to poor outcomes from this highly morbid and potentially lethal infection. We performed a case-control study in a regional, high-volume, tertiary care, academic medical center over the years 2005-2015 to assess the potential changing epidemiology, clinical and laboratory(More)
