To the Editor: Filoviruses cause highly lethal hemorrhagic fever in humans and nonhuman primates, except for Reston Ebolavirus (REBOV), which causes severe hemorrhagic fever in macaques (1,2). REBOV epizootics among African fruit bats have been suggested to be natural reservoirs for Zaire Ebolavirus and Marburg virus (4–6). However, the natural reservoir of(More)
Fifty-two bats captured during July 2008 in the Philippines were tested by reverse transcription-PCR to detect bat coronavirus (CoV) RNA. The overall prevalence of virus RNA was 55.8%. We found 2 groups of sequences that belonged to group 1 (genus Alphacoronavirus) and group 2 (genus Betacoronavirus) CoVs. Phylogenetic analysis of the RNA-dependent RNA(More)
Bat coronavirus (BtCoV) is assumed to be a progenitor of severe acute respiratory syndrome (SARS)-related coronaviruses. To explore the distribution of BtCoVs in the Philippines, we collected 179 bats and detected viral RNA from intestinal or fecal samples by RT-PCR. The overall prevalence of BtCoVs among bats was 29.6 %. Phylogenetic analysis of the(More)
In this study, cDNA of Toll-like receptors (TLR) 3, 7 and 9 were synthesized and completely sequenced. The coding regions of cDNA for bat TLR3, TLR7 and TLR9 were 2,718, 3,150 and 3,090 bp in length, respectively. The open reading frames encoded 905, 1,049 and 1,029 amino acids for TLR3, TLR7 and TLR9, respectively. The nucleotide sequences, predicted amino(More)
BACKGROUND Acyclovir (ACV)-resistant (ACVr) herpes simplex virus type 1 (HSV-1) infections are concern in immunocompromised patients. Most clinical ACVr HSV-1 isolates have mutations in the viral thymidine kinase (vTK) genes. The vTK-associated ACVr HSV-1 shows reduced virulence, but the association between the level of resistance and the virulence of the(More)
