[Q]: Electron microscopy (EM) allows fast visualization of viruses in a wide range of clinical specimens. Viruses are grouped into families based on their morphology. Viruses from various families look distinctly and these morphological variances are the basis for identification of viruses by EM. The identification to the family level is often sufficient for the clinician or recognition of an unknown infectious agent. Diagnostic EM has two advantages over enzyme-linked immunosorbent assay and nucleic acid amplification tests. After a simple and fast negative staining, EM allows fast morphological identification and differential diagnosis of infectious agents contained in the specimen without the need for special considerations and/or reagents. Nevertheless, EM has the disadvantage of being unsuitable as a screening method.

[Q]: The present study describes the development of SYBR Green based real-time polymerase chain reaction (real-time PCR) for detection and quantitation of canine parvovirus type 2 (CPV 2) in faecal samples of dogs. In this assay, the primers were designed and custom-synthesized based on nucleotide sequence of VP2 gene of CPV 2. A standard curve was plotted using 10-fold serial dilution of standard plasmid DNA and Ct value. The standard curve was found to be linear over a 10 −7 dilution. The real-time PCR results were expressed as the number of DNA copies of CPV 2 per mg of faecal samples and showed range of 1.0 × 10 3 to 7.0 × 10 9 copies of viral DNA per mg of stool samples. The analytical sensitivity of the SYBR Green based real-time PCR was shown to be equivalent to 10 copies. Faecal samples (47) from dogs suspected of CPV 2 infection were analyzed by real-time PCR, haemagglutination (HA) assay and by a conventional PCR and 24, 20 and 22 samples were found positive for CPV 2, respectively. Comparison between the results of three different assays revealed that real-time PCR is more sensitive than HA and conventional PCR and allow the detection of low titers of CPV 2 in infected dogs.

[Q]: Bamboo mosaic virus (BaMV) has a positive-sense single-stranded RNA genome with a 5′ cap and a 3′ poly (A) tail. To characterize polyadenylation activity in the BaMV replicase complex, we performed the in vitro polyadenylation with various BaMV templates. We conducted a polyadenylation activity assay for BaMV RNA by using a partially purified BaMV replicase complex. The results showed that approximately 200 adenylates at the 3′ end of the RNA were generated on the endogenous RNA templates. Specific fractions derived from uninfected Nicotiana benthamiana plants enhanced the polyadenylation activity, implying that host factors are involved in polyadenylation. Furthermore, polyadenylation can be detected in newly synthesized plus-strand RNA in vitro when using the exogenous BaMV minus-strand minigenome. For polyadenylation on the exogenous plus-strand minigenome, the 3′ end requires at least 4A to reach 22% polyadenylation activity. The results indicate that the BaMV replicase complex recognizes the 3′ end of BaMV for polyadenylation.
