Previous documented examples of infections in humans by canine-like rotavirus strains have been associated with either asymptomatic (strains HCR3A and HCR3B) or symptomatic (strain Ro1845) clinical forms of disease (4, 5, 12 ).
Region xfp4 is present in low copy number in both symptomatic and non-symptomatic strains (56a, 9.12c and CV21) and in equal copy numbers in the other strains.
Several studies have found that NSP4 has been associated with altered virulence, by sequence comparison of symptomatic and asymptomatic strains isolated from serotypically identical human strains (30, 31 ) or symptomatic and asymptomatic porcine strains tested in a mouse model (36 ), or by gene reassortment studies in a piglet model (37 ).
If Aeromonas enteric infections are transmitted by drinking water and symptomatic infections are strain-specific, then the same strains isolated from patients with acute gastroenteritis should be found in drinking water.
Beyond the hugs and photo ops, relations between the US and Brazil have become symptomatic of greater strains created by an antiquated inter- Inter-American system that is unraveling after more than a century of primus inter pares diplomacy by Washington.
Probiotic intervention protocols using an avirulent Escherichia coli strain to prevent symptomatic infection with virulent strains, found a small benefit to those with SCI in terms of reduced number of UTIs.
Strains 317 (ATCC 14019) and 594 (ATCC 14018) were isolated from the vaginal tracts of women with symptomatic BV, while Strain 409-05 was isolated from a healthy, asymptomatic individual with a Nugent score of 9. Substantial genomic rearrangement and heterogeneity were observed that appeared to have resulted from both mobile elements and substantial lateral gene transfer.
Mitch McConnell and John Boehner are not popular politicians in Europe, let alone in France, where their party's antics are often seen as symptomatic of the worst strains of American provincialism.
But in a television interview broadcast Tuesday in Japan, Obama said he "would be honored to have the opportunity to visit those cities at some point during my presidency". Japan's focus on the possibility of a presidential visit to Hiroshima and Nagasaki is symptomatic of the emerging strains and enduring strengths of the United States' relationship with its closest ally in Asia.
A previous study of microarray hybridization was carried out in order to compare six different citrus-associated Xylella strains from symptomatic and asymptomatic plants isolated in South American (using as reference the 9a5c strain genome) (for further information, refer to da Silva et al [27] and GEO database, entry GSE8493).
In Africa, the P[6] type is identified much more commonly and can represent more than 50% of strains from symptomatic infections [ 28, 29].
