- flame vaccine Related technology
- Infectious laryngotracheitis is caused by infection with infectious laryngotracheitis virus (ILTV).
- ILTV infects birds such as nits, pheasants, peacocks and turtles. Characteristics of the onset in the nits include respiratory symptoms, increased body temperature, decreased appetite, etc., as well as strong cough and sputum expectoration. In the case of laying hens, the laying rate decreases from about 4 days after onset, and it takes about one month to return to normal laying. In addition, increased mortality due to mixed infection with other pathogens has been reported, causing a significant economic loss to the poultry industry.
- a live attenuated vaccine strain and a live frozen vaccine have been used.
- the immunity effect varies depending on the breeding environment, breeding density, inoculation method, etc.
- vaccination may cause some symptoms in the respiratory system, and improper use and dose may lead to disease.
- ILTV is a type of virus belonging to the genus Herpes. It consists of 60,000 base pairs of double-stranded DNA. At present, most genes have not been identified, and only a small amount of the thymidine kinase gene (Griffin et al., J. Gen. Virol., Vol. 71 p. 841, 199), the gp60 gene (Kongsuwan et al., Virus Genes, Vol. 7, pp. 297-303, 1993), the force pseudo p40 gene (G 18 p. 3664, 1990), the glycoprotein B (gB) gene (Pou 1sen et al., Virus 5 p. 33 5 — 347, 1991), the glycoprotein C (g C) gene (Kingsley et al., Virology, Vol. 3 3 6-3 4 3, 1 9 9 4), RR 2 gene

- the gene encoding the polypeptide described in SEQ ID NO: 1 (UL32h gene) of the present invention is homologous to the UL32 gene of HSV-1.
- the HSV-1 UL32 gene is located about 15 kbp from the gB gene to the internal repeat on the long unique region, and is also a viral virus.
- the gene arrangement between genera is very similar (Roizman and Ears, Virology, Econdition, Chater 65, 179-5-184, 199). This suggests that, even on the ILTV genome, the UL32h gene is expected to be present on the internal repeat side from the gB gene.
- an IGEM-12 library of the NS-175 strain genome of ILTV was prepared, and the library was constructed from the library. A clone that hybridizes to the ILTV gB gene is selected, and then a clone that hybridizes to the internal repeat-side fragment of the ILTV genomic DNA of the clone is selected. Gene walking was repeated to make further selections.
- the DNA fragment derived from the ILTV genome obtained in this manner was subjected to sequence analysis, and the amino acid sequence deduced from the sequence was compared with the amino acid sequence of UL32 polypeptide of HSV-1.
- HSV-1 An open reading frame encoding a polypeptide homologous to the amino acid sequence of the UL32 polypeptide of / 0786612 was obtained.
- the DNA sequence and the deduced amino acid sequence are shown in SEQ ID NO: 2.
