This paper describes the detection of a novel herpesvirus in a Serotine bat (Eptesicus serotinus) in Hungary. The rescued animal showed signs of icterus and anorexia and died within a day, in spite of immediate supportive therapy. Autopsy confirmed the clinical picture by the major lesions observed in the liver. Histopathology revealed vacuolar degeneration in the hepatocytes and leukocytosis in the sinusoidal lumina. By electron microscopy, hydropic degeneration and apoptotic cells with a pycnotic nucleus were found in the liver. Bacteriological examinations gave negative results. As part of a routine screening project, detection of adeno-and herpesviruses from homogenised samples of the liver, lungs and small intestines was attempted by nested polymerase chain reaction (PCR) assays. The adenovirus PCR ended with negative results. The herpesvirus PCR resulted in an amplification product of specific size. The nucleotide sequence of the amplicon was determined and analysed by homology search and phylogenetic analysis. A novel herpesvirus was identified, which seemed to be most closely related to members of the genus Rhadinovirus within the subfamily Gammaherpesvirinae. The causative role of the detected rhadinovirus in the fatal condition of the Serotine bat could not be proven, but it is most likely that reactivation from a latent infection allowed the detection of the virus by PCR.

“…EDSV mainly causes sudden drop in egg production in laying birds accompanied by a reduction in egg quality. In 2001, a case was reported in young goslings with severe acute respiratory disease in Hungary, and the infectious agent was confirmed to be the EDSV by the viral isolation, serological and genomic examinations, and experimental infection of 1-day-old goslings (3). Cha et al (4) also found that EDSV caused severe acute respiratory symptoms in 10-day-old Pekin ducklings.…”

Egg drop syndrome virus (EDSV) strain FJ12025 was isolated from a 9-day-old Muscovy duckling. The results of the sequence showed that the genome of strain FJ12025 is 33,213 bp in length, with a G+C content of 43.03%. When comparing the genome sequence of strain FJ12025 to that of laying duck original strain AV-127, we found 50 single-nucleotide polymorphisms (SNPs) between the two viral genome sequences. A genomic sequence comparison of FJ12025 and AV-127 will help to understand the phenotypic differences between the two viruses.

“…6 Furthermore, DAdV-A has also been isolated from young goslings suffering from acute respiratory symptoms indicating that DAdV-A is also able to induce disease in geese. 11 In addition, quail were shown to become infected with DAdV-A and to develop classical signs of EDS-76. 5 The susceptibility of chickens to infection with DAdV-A is age independent.…”

Development of a new real-time polymerase chain reaction assay to detect Duck adenovirus A DNA and application to samples from Swiss poultry flocks

Abstract. Between 2008 and 2012, commercial Swiss layer and layer breeder flocks experiencing problems in laying performance were sampled and tested for infection with Duck adenovirus A (DAdV-A; previously known as Egg drop syndrome 1976 virus). Organ samples from birds sent for necropsy as well as blood samples from living animals originating from the same flocks were analyzed. To detect virus-specific DNA, a newly developed quantitative real-time polymerase chain reaction method was applied, and the presence of antibodies against DAdV-A was tested using a commercially available enzymelinked immunosorbent assay. In 5 out of 7 investigated flocks, viral DNA was detected in tissues. In addition, antibodies against DAdV-A were detected in all of the flocks.
