Abstract
This study describes group A rotavirus (RVA) genotype prevalence in Belarus from 2008 to 2012. In 2008, data from 3 sites in Belarus (Brest, Mogilev, Minsk) indicated that G4P[8] was the predominant genotype. Data from Minsk (2008-2012) showed that G4P[8] was the predominant RVA genotype in all years except in 2011 when G3P[8] was most frequently detected. Other RVA genotypes common in Europe (G1P[8], G2P[4]) were detected each year of the study. This study reveals the dominance of genotype G4P[8] in Belarus and helps to establish the baseline genotype prevalence prior to RVA vaccine introduction in the country.

Abstract
In 2006-07, 77 cases of gastroenteritis in Rochester, NY, USA were associated with rotavirus genotype G12P[8]. Sequence analysis identified a high degree of genetic relatedness among the VP7 and VP4 genes of the Rochester G12P[8] strains and between these strains and currently circulating human G12P[8] strains. Out of 77 samples, two and seven unique nucleotide sequences were identified for VP7 and VP4 genes, respectively. Rochester strain VP7 genes were found to occupy the G12-III lineage and VP4 genes clustered within the P[8]-3 lineage. Six strains contained non-synonymous nucleotide substitutions that produced amino acid changes at 6 sites in the VP8(∗) region of the VP4 gene. Two sites (amino acids 242 and 246) were located in or near a described trypsin cleavage site. Selection analyses identified one positively selected VP7 site (107) and strong purifying selection at 58 sites within the VP7 gene as well as 2 of the 6 variant sites (79 and 218) in VP4.

Abstract
Knowledge from early outbreaks is limited regarding the virus detection and illness duration of the 2009 pandemic influenza A (H1N1) infections. During the period from April to May 2009 in Texas, we collected serial nasopharyngeal (NP) and stool specimens from 35 participants, testing by real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) and culture. The participants were aged 2 months to 71 years; 25 (71%) were under 18. The median duration of measured fever was 3.0 days and of virus detection in NP specimens was 4.2 days; however, few specimens were collected between days 5-9. The duration of virus detection (4.2 days) was similar to the duration of fever (3.5 days) (RR, 1.14; 95% CI, .66-1.95; P = .8), but was shorter than the duration of cough (11.0 days) (RR, .41; 95% CI, .24-.68; P < .001). We detected viral RNA in two participants' stools. All cultures were negative. This investigation suggests that the duration of virus detection was likely similar to the seasonal influenza virus.

Abstract
BACKGROUND Rotavirus vaccine was recommended for routine use among US infants in 2006. To provide prevaccine data, we conducted strain surveillance for 9 consecutive seasons during 1996-2005. METHODS Using reverse-transcriptase polymerase chain reaction genotyping and nucleotide sequencing, we determined P/G genotypes of >3100 rotavirus strains collected in up to 12 cities each year from different US regions. RESULTS The most prevalent strain globally, P[8] G1, was the most prevalent each year in the United States (overall, 78.5% of strains; range, 60.0%-93.9%), and 9.2% of the samples were P[4] G2, 3.6% were P[8] G9, 1.7% were P[8] G3, and 0.8% were P[8] G4. Genotype P[6] G9, which emerged in 1995, was detected continuously for several seasons (from 1996-1997 to 2000-2001, 0.2%-5.4%) but was not identified in the subsequent 4 seasons. Single or a few detections of rare genotypes (eg, P[6] G12, P[9] G6, and P[9] G3) were observed during several rotavirus seasons at frequencies of 0.5%-1.7% and, overall, comprised 0.6% of all the samples from the entire surveillance period. Several globally common strains in addition to G1, especially G2 and G9, circulated at high prevalence (33%-62%) in some cities during certain years. CONCLUSIONS Almost 85% of strains during 1996-2005 had either a G or P antigen that is present in both RotaTeq (Merck) and Rotarix (GlaxoSmithKline). Monitoring of strains after introduction of rotavirus vaccines is important.

Abstract
We sequenced 22 VP6 genes from common rotavirus strains P[8], G1; P[4], G2; P[8], G3; P[8], G4 and P[8], G9 and uncommon type P[6], G9 collected in the US over a 6-year period. All strains defined as members of VP6 antigenic subgroup (SG) I according to reactivity patterns with monoclonal antibodies formed a genetic cluster (Genogroup I) with SG I reference strains. Similarly, all strains in antigenic SGII formed a group (Genogroup II) with corresponding standard strains of the same SG. Most US strains of each genogroup had diverged by 10-15% from the VP6 gene sequence of reference strains collected >20 years earlier and some recent isolates from other countries. Evolutionary analysis demonstrated that recently isolated US strains of both genogroups have diverged into 2-3 related clusters consistent with other recent findings. Unexpectedly, some recent isolates from other countries have diverged greatly from both older reference isolates and from the recent US isolates characterized here. This finding suggests that genetic diversity in human rotavirus VP6 genes may be greater than previously recognized. These sequences will help in the construction of a VP6 gene database to aid in the development of broadly reactive molecular assays and permit identification of regions where primers and probes for existing assays may need to be redesigned.

Abstract
In female mice, anogenital distance (AGD), measured at weaning, provides an estimate of uterine exposure to testosterone from flanking male mouse littermates. A variant of the anogenital distance index (AGDI) that uses the residual value of AGD after accounting for the effect of weight by regression (AGDWTRES) was measured at weaning in F(2) female mice from a C57BL/6J x DBA2/J cross. AGDWTRES was used to examine the relationship between intrauterine environment and blood chemistry variables and activity-related behaviors when the females were 450 days old. Longer AGDWTRES values correlated with lower levels of calcium, cholesterol, phosphorus, iron, and protein, which is opposite to the expected direction, based on underlying sex differences for blood chemistry. A positive correlation was found between AGDWTRES and two activity-related measures (the number of rears in a test of exploration, and the number of sectors of a rod that are entered by the mouse). These findings suggest that in utero proximity to males, as indexed by AGDWTRES, may have effects on fundamental aspects of blood chemistry and behavior that extend well into mouse middle age, and could play an important role in health.
