Archived formalin-fixed, paraffin-embedded tissues from 28 diseased ornamental cichlid fish associated with visceral granulomas were examined by polymerase chain reaction (PCR) and in situ hybridization (ISH) for detection of Francisella-like bacteria (FLB). The 16S rDNA FLB-specific primer pair 180f/465r was used on naturally infected ornamental cichlids,(More)
A monoclonal antibody (MAb) was generated against the capsid protein (ORF 72) of koi herpesvirus (KHV) isolated from diseased koi Cyprinus carpio in Taiwan. The clone of MAb-B2 was obtained by immunizing mice with whole virus particles and further identified using indirect enzyme-linked immunosorbent assay and Western blot assay. In addition, it detected(More)
Isolates of Newcastle disease virus (NDV) from chicken cases were obtained from various locations in Taiwan during 2003-2006 and were genotypically analyzed by using reverse transcription polymerase chain reaction (RT-PCR) with primers specific to the viral fusion (F) protein gene (534 bp). Part of the amplified F protein DNA product (nucleotide sequence(More)
investigated in milkfish Chanos chanos, which had a cumulative mortality of up to 66.7% over the course of 1 yr. Gross reddish- or greyish-white nodules appeared on the peritoneal surface, spleen, kidney, liver and gastrointestinal (GI) tract. Epithelioid granulomas with the formation of Langhan's type giant cells were the prominent histopathological(More)
C-Terminal truncation mutagenesis was used to explore the functional and structural significance of the C-terminal region of Aeromonas caviae D1 chitinase (AcD1ChiA). Comparative studies between the engineered full-length AcD1ChiA and the truncated mutant (AcD1ChiAK606) included initial rate kinetics, fluorescence and circular dichroism (CD) spectrometric(More)
This paper demonstrates a measurement technique for the frontend circuit and the completed system of a RFID transponder at UHF, based on the self-designed RFID reader and transponder. A brief introduction of the system is given, along with the detailed measurement procedure and measurement result. The proposed analog frontend circuit achieves a maximum(More)
Between December 2013 and January 2014, five outbreaks of an unknown disease with moderate to high cumulative mortality were observed among the freshwater redclaw crayfish (Cherax quadricarinatus) populations at four crayfish farms in Miaoli and Changhua counties (northern Taiwan) and at one crayfish farm in Pingtung County (southern Taiwan). Polymerase(More)
