During a study of the development of infectious laryngotracheitis (LT) virus in tissue culture cells, unusual tubular formations were found in the cytoplasm of a small proportion of the affected cells. It is the purpose of this report to describe the morphologic characteristics of the tubules and to discuss their possible association with the development of virus.The source and maintenance of the strain of LT virus have been described. Prior to this study, the virus was passed several times in chicken embryo kidney (CEK) tissue culture cells.

In Ovo

The use of intensive selection procedure in modern broiler chicken lines has led to the development of several skeletal disorders in broiler chickens. Therefore, current research is focused on methods to improve the bone quality in birds. In ovo technology, using nanoparticles with a high specificity to bones, is a potential approach. The present study aimed to evaluate the effect of in ovo inoculation (IOI) of calcium carbonate nanoparticles (CCN) on chicken embryo development, health status, bone characteristics, and on broiler production results and bone quality. After assessing in vitro cell viability, the IOI procedure was performed with an injection of 500 μg/mL CCN. The control group was not inoculated with CCN. Hatchability, weight, and selected bone and serum parameters were measured in embryos. Part of hatchlings were reared under standard conditions until 42 days, and production results, meat quality, and bone quality of broilers were determined. CCN did not show cytotoxicity to cells and chicken embryo and positively influenced bone parameters of the embryos and of broilers later (calcification) without negatively affecting the production results. Thus, the IOI of CCN could modify the molecular responses at the stage of embryogenesis, resulting in better mineralization, and could provide a sustained effect, thereby improving bone quality in adult birds.

AbstractIn recent years, with the participation of genetics and other disciplines, the controversy on the origins of the domestic chicken has returned. As the resource of primary data, archaeology plays an extremely important role in this dispute. Taking an archaeological standpoint, this paper aims to establish a set of bone morphological identification standards for domestic chicken bones unearthed at archaeological remains, beginning with the bone morphology as the most basic but also the least studied aspect. By this set of standards, we reanalyze available chicken bone materials and relevant pictorial and textual materials for domestic chicken candidate samples as mentioned by previous scholars. The results show that no confirmed domestic chicken bones have been found in China’s early to mid-Holocene remains to date; meanwhile, there is no substantial archaeological evidence to support China as the earliest place of origin of domestic chicken. Future work seeking to advance research on the origin of the domestic chicken should first pay proper attention to the archaeological background; only continuing scientific analyses and exploration on the origin of domestic chicken based on scientific morphological identification will prove the most convincing methodology.
