Abstract
Phylogenetic analyses can give new insights into the evolutionary history of viruses, especially of viruses with segmented genomes. However, sequence information for many viral families or genera is still limited and phylogenies based on single or short genome fragments can be misleading. We report the first genetic analysis of all three genome segments of Wyeomyia group viruses Wyeomyia, Taiassui, Macaua, Sororoca, Anhembi and Cachoeira Porteira (BeAr328208) in the genus Orthobunyavirus of the family Bunyaviridae. In addition, Tucunduba and Iaco viruses were identified as members of the Wyeomyia group. Features of Wyeomyia group members that distinguish them from other viruses in the Bunyamwera serogroup and from other orthobunyaviruses, including truncated NSs sequences that may not counteract the host's interferon response, were characterized. Our findings also suggest genome reassortment within the Wyeomyia group, identifying Macaua and Tucunduba viruses as M-segment reassortants that, in the case of Tucunduba virus, may have altered pathogenicity, stressing the need for whole-genome sequence information to facilitate characterization of orthobunyaviruses and their phylogenetic relationships.

Abstract
A duplex TaqMan real-time reverse transcriptase polymerase chain reaction (PCR) assay was developed for the detection of California (CAL) serogroup viruses and Cache Valley virus (CVV), for use in human surveillance. The targets selected for the assay were the sequences encoding the nucleocapsid protein of CAL and the G1 glycoprotein of CVV. Conserved regions were selected by aligning genetic sequences from various strains available in the GenBank database. Primers and probes were selected in conserved regions. The assay sensitivity was 75 gene copies (gc)/reaction for CAL serogroup viruses and 30 gc/reaction for CVV. The performance of the assay was linear over at least 6 log(10) gc. The assay was specific, given that it did not cross-react with a variety of pathogens. It did, however, detect 11 viruses within the CAL serogroup and 12 CVV isolates. The use of an internal control ensured that possible inefficiency in nucleic acid extraction or PCR inhibition would be detected.

Abstract
Maguari virus (MAGV; genus Orthobunyavirus, family Bunyaviridae) contains a tripartite negative-sense RNA genome. Like all orthobunyaviruses, the medium (M) genome segment encodes a precursor polyprotein (NH(2)-Gn-NSm-Gc-COOH) for the two virion glycoproteins Gn and Gc and a nonstructural protein NSm. The nucleotide sequences of the M segment of wild-type (wt) MAGV, of a temperature-sensitive (ts) mutant, and of two non-ts revertants, R1 and R2, that show electrophoretic mobility differences in their Gc proteins were determined. Twelve amino acid differences (2 in Gn, 10 in Gc) were observed between wt and ts MAGV, of which 9 were maintained in R1 and R2. The M RNA segments of R1 and R2 contained internal deletions, resulting in the removal of the N-terminal 239 residues of Gc (R1) or the C-terminal two thirds of NSm and the N-terminal 431 amino acids of Gc (R2). The sequence data were consistent with analyses of the virion RNAs and virion glycoproteins. These results suggest that neither the N-terminal domain of Gc nor an intact NSm protein is required for the replication of MAGV in tissue culture.

Abstract
Guaroa virus (GROV), a segmented virus in the genus Orthobunyavirus, has been linked to the Bunyamwera serogroup (BUN) through cross-reactivity in complement fixation assays of S segment-encoded nucleocapsid protein determinants, and also to the California serogroup (CAL) through cross-reactivity in neutralization assays of M segment-encoded glycoprotein determinants. Phylogenetic analysis of the S-segment sequence supported a closer relationship to the BUN serogroup for this segment and it was hypothesized that the serological reaction may indicate genome-segment reassortment. Here, cloning and sequencing of the GROV M segment are reported. Sequence analysis indicates an organization similar to that of other orthobunyaviruses, with genes in the order GN-NSm-Gc, and mature proteins generated by protease cleavage at one, and by signalase at possibly three, sites. A potential role of motifs that are more similar to CAL than to BUN virus sequences with respect to the serological reaction is discussed. No discernable evidence for reassortment was identified.

Abstract
A virus isolated from dead Chaerephon plicata bats collected near Kampot, Cambodia, was identified as a member of the family Bunyaviridae by electron microscopy. The only bunyavirus previously isolated from Chaerephon species bats in South-East Asia is Kaeng Khoi (KK) virus (genus Orthobunyavirus), detected in Thailand over 30 years earlier and implicated as a public health problem. Using RT-PCR, nucleotide sequences from the M RNA segment of several virus isolates from the Cambodian C. plicata bats were found to be almost identical and to differ from those of the prototype KK virus by only 2.6-3.2 %, despite the temporal and geographic separation of the viruses. These results identify the Cambodian bat viruses as KK virus, extend the known virus geographic range and document the first KK virus isolation in 30 years. These genetic data, together with earlier serologic data, show that KK viruses represent a distinct group within the genus Orthobunyavirus.

Abstract
In late 1997 and early 1998, a large outbreak of hemorrhagic fever occurred in East Africa. Clinical samples were collected in Kenya and southern Somalia, and 27 of 115 (23%) hemorrhagic fever patients tested showed evidence of acute infection with Rift Valley fever (RVF) virus as determined by IgM detection, virus isolation, detection of virus RNA by reverse transcription-polymerase chain reaction (RT-PCR), or immunohistochemistry. However, two patients (one from Kenya and the other from Somalia) whose illness met the hemorrhagic fever case definition yielded virus isolates that were not RVF. Electron microscopy suggested these two virus isolates were members of the family Bunyaviridae. RT-PCR primers were designed to detect bunyavirus RNA in these samples. Regions of the S and L segments of the two isolates were successfully amplified, and their nucleotide sequences exhibited nearly complete identity with Bunyamwera virus, a mosquito-borne virus not previously associated with severe human disease. Unexpectedly, the virus M segment appeared to be reassorted, as the sequences detected exhibited 32-33% nucleotide and 28% amino acid differences relative to the corresponding M segment sequence of Bunyamwera virus. The association of this reassortant bunyavirus, proposed name Garissa virus, with severe disease is supported by the detection of the virus RNA in acute-phase sera taken from 12 additional hemorrhagic fever cases in the region.
