Example Input: A nested PCR assay was used to determine the viral RNA and proviral DNA status of naturally infected cats. Selected samples that were FeLV-positive by PCR were subjected to sequencing, phylogenetic analysis, and motifs search. Of the 39 samples that were positive for FeLV p27 antigen, 87.2% (34/39) were confirmed positive with nested PCR. FeLV proviral DNA was detected in 38 (97.3%) of p27-antigen negative samples. Malaysian FeLV isolates are found to be highly similar with a homology of 91% to 100%. Phylogenetic analysis revealed that Malaysian FeLV isolates divided into two clusters, with a majority (86.2%) sharing similarity with FeLV-K01803 and fewer isolates (13.8%) with FeLV-GM1 strain. Different enhancer motifs including NF-GMa, Krox-20/WT1I-del2, BAF1, AP-2, TBP, TFIIF-beta, TRF, and TFIID are found to occur either in single, duplicate, triplicate, or sets of 5 in different positions within the U3-LTR-gag region. The present result confirms the occurrence of FeLV viral RNA and provirus DNA in naturally infected cats. Malaysian FeLV isolates are highly similar, and a majority of them are closely related to a UK isolate. This study provides the first molecular based information on FeLV in Malaysia. Additionally, different enhancer motifs likely associated with FeLV related pathogenesis have been identified.
Example Output: Molecular Detection, Phylogenetic Analysis, and Identification of Transcription Motifs in Feline Leukemia Virus from Naturally Infected Cats in Malaysia

Example Input: Tacaribe virus (TCRV) is a mammalian arenavirus that was first isolated from artibeus bats in the 1950s. Subsequent experimental infection of Jamaican fruit bats (Artibeus jamaicensis) caused a disease similar to that of naturally infected bats. Although substantial attention has focused on bats as reservoir hosts of viruses that cause human disease, little is known about the interactions between bats and their pathogens. We performed a transcriptome-wide study to illuminate the response of Jamaican fruit bats experimentally infected with TCRV. Differential gene expression analysis of multiple tissues revealed global and organ-specific responses associated with innate antiviral responses, including interferon alpha/beta and Toll-like receptor signaling, activation of complement cascades, and cytokine signaling, among others. Genes encoding proteins involved in adaptive immune responses, such as gamma interferon signaling and costimulation of T cells by the CD28 family, were also altered in response to TCRV infection. Immunoglobulin gene expression was also elevated in the spleens of infected bats, including IgG, IgA, and IgE isotypes. These results indicate an active innate and adaptive immune response to TCRV infection occurred but did not prevent fatal disease. This de novo assembly provides a highthroughput data set of the Jamaican fruit bat and its host response to TCRV infection, which remains a valuable tool to understand the molecular signatures involved in antiviral responses in bats.
Example Output: Transcriptomic Signatures of Tacaribe Virus-Infected Jamaican Fruit Bats

Example Input: The explosive pace of sequencing of RNA viruses is leading to rapid advances in our understanding of the evolution of these viruses and of the ways in which their genomes are organized and expressed. New insights are coming not only from genomic nucleotide sequence comparisons, but also from direct sequencing of transcribed mRNAs and of RNAs that serve as intermediates in replication.
