Background: Hydroxyapatite (HA) is a material with excellent bioactivity and chemical similarity to bone. It can be extracted from natural sources or fabricated synthetic sources.
Objective: To synthesize HA from domestic chicken eggshells and to characterize it using Fourier transform infrared (FTIR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy, and cell viability.
Materials And Methods: Domestic chicken eggshells (Indian breed "Aseel") were used to synthesize HA through the chemical precipitation method. The processing was conducted at an elevated temperature (900°C). Characterization of the sample was performed using, FTIR, SEM, EDS, and XRD. The cell viability was tested using methyl thiazolyl tetrazolium assay.
Results: Phosphate and calcium ions were confirmed by FTIR and EDS. The carbonate peaks observed were typical of biological apatite. XRD revealed its crystalline property. SEM analysis confirmed the particle size to be less than 100 μm and the presence of a porous structure. The material was found to be noncytotoxic and favored cell growth.
Conclusion: The synthesized HA showed a crystalline nature and had good cell viability. Hence, it may be considered as a material for various biomedical applications.

H3N3 avian influenza viruses (AIVs) are less prevalent in poultry than H3N8 viruses. However, although relatively rare, reassortant H3N3 viruses have been known to appear in both domestic poultry and wild birds. In this study, we isolated the H3N3 virus in chickens sourced from a live poultry market in China.

Low pathogenic avian influenza viruses (LPAIVs) persist in poultry populations, posing an ongoing challenge to poultry management and research. These viruses typically cause mild infections but can lead to significant economic losses due to their widespread presence and potential to disrupt poultry production. Traditional in vivo and in vitro models struggle to accurately replicate the avian intestinal environment, where these viruses often establish infection.
