Horizontal transmission of turkey herpesvirus (HVT) was studied in three separate trials using three different lines of chickens in each trial. There was no horizontal spread of HVT to contact cagemates through 8 weeks regardless of the line of donor chickens, when inoculated subcutaneously with 9.2 times 10-3 plaque-forming units (PFU) of HVT at 1 week of age. The virus spread poorly to a few cagemates from an experimental line of White Leghorns (W.S.U.-V.S.), but not from a commercial line of White Leghorns (C.-W.L.) or meat-type (C.-M.T.) chickens, when inoculated with 9.4 times 10-4 PFU of HVT at 1 week of age. The virus spread readily to contact cagemates from W.S.U.-V.S. but not at all from C.-W.L. or C.-M.T. chickens when inoculated with 2 times 10-4 PFU of HVT at 8 weeks of age. The incidence among cagemates of contact infection by HVT appeared similar regardless of genetic lines. This observation indicated a difference among different genetic lines of chickens in the development and/or shedding of infectious HVT following virus inoculation.
在三项独立试验中研究了火鸡疱疹病毒（HVT）的水平传播，每项试验使用三个不同品系的鸡。无论供体鸡的品系如何，1周龄时皮下接种9.2×10⁻³ 蚀斑形成单位（PFU）的HVT后，在8周内HVT均未水平传播至接触的同笼鸡。1周龄时接种9.4×10⁻⁴ PFU的HVT后，病毒从实验品系的白来航鸡（W.S.U.-V.S.）少量传播至一些同笼鸡，但未从商业品系的白来航鸡（C.-W.L.）或肉用型鸡（C.-M.T.）传播。8周龄时接种2×10⁻⁴ PFU的HVT后，病毒很容易从W.S.U.-V.S.传播至接触的同笼鸡，但完全未从C.-W.L.或C.-M.T.鸡传播。无论遗传品系如何，HVT接触感染在同笼鸡中的发生率似乎相似。这一观察结果表明，不同遗传品系的鸡在接种病毒后传染性HVT的发育和/或排出方面存在差异。
