Phylogeny of the major lineages of Membracoidea (Insecta: Hemiptera: Cicadomorpha) based on 28S rDNA sequences.
Analysis of sequences from a 3.5-kb region of the nuclear ribosomal 28S DNA gene spanning divergent domains D2-D10 supports the hypothesis, based on fossil, biogeographic, and behavioral evidence,Expand
Epidemiology of rotavirus diarrhea in Egyptian children and implications for disease control.
Reliable epidemiologic data are essential for formulating effective policy to control rotavirus disease through immunization. The objective of this study was to describe the epidemiology of rotavirusExpand
Detection and Characterization of Novel Rotavirus Strains in the United States
Both sequence analysis of the VP7 open reading frame and binding to a G9-specific monoclonal antibody strongly suggest that U.S. G9 strains belong to serotype G9, which could suggest the emergence of new strains or inadequate diagnosis in the past. Expand
Genetic variability among serotype G6 human rotaviruses: Identification of a novel lineage isolated in Hungary
This study sequenced the VP7 genes and VP8* gene fragments of human rotavirus G6 strains detected in Hungary and revealed that the single PA169‐like Hungarian G6 strain belonged to genotype P[14] and was phylogenetically closely related to P11[14],G6 strains characterized previously. Expand
Astrovirus diarrhea in Egyptian children.
There was evidence to suggest HAstV-1 homotypic immunity but not heterotypes immunity, and a candidate astrovirus vaccine would have to confer immunity very early in life. Expand
Isolation and Expression of cDNAs from Rainbow Trout (Oncorhynchus mykiss) That Encode Two Novel Basic Helix-Loop-Helix/PER-ARNT-SIM (bHLH/PAS) Proteins with Distinct Functions in the Presence of the
cDNAs encoding two distinct basic helix-loop-helix/PER-ARNT-SIM (bHLH/PAS) proteins with similarity to the mammalian aryl hydrocarbon nuclear translocator (ARNT) protein were isolated from RTG-2 rainbow trout gonad cells and mRNAs for both rtARNT splice variants were detected. Expand
Early-phase transmission of Yersinia pestis by cat fleas (Ctenocephalides felis) and their potential role as vectors in a plague-endemic region of Uganda.
Plague control programs in this region should remain focused on reducing rat flea populations, although the findings imply that cat fleas should not be ignored by these programs as they could play a significant role as secondary vectors. Expand
Determination of aryl hydrocarbon receptor nuclear translocator protein concentration and subcellular localization in hepatic and nonhepatic cell culture lines: development of quantitative Western
Immunocytochemical staining of each cell line showed that ARNT was exclusively localized to the nuclear compartment and that a conserved nuclear localization signal mapped to the NH-terminal portion of the protein. Expand
Characterization of unusual G8 rotavirus strains isolated from Egyptian children
It is demonstrated that the understanding of the geographic distribution of rotavirus strains is incomplete, the need to monitor rota- virus serotypes is emphasized, and the known distribution of serotype G8 and genotype P[14] strains in Africa is extended. Expand
Reassessment of Dalbulus Leafhopper (Homoptera: Cicadellidae) Phylogeny Based on Mitochondrial Dna Sequences
The resulting tree supports the hypothesis that the ancestral hosts of Dalbulus were gamagrasses ( Tripsacum spp.) and that the acquisition of a preference for maize arose independently in 2 DalBulus lineages. Expand
