Pathogens are an important and significant hazard for human and animal health. In recent years, antibiotics are used to treat different types of infection caused by bacterial agents. In veterinary medicine, antibiotics injected into hatching eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major conc...

Avirulent (lentogenic) strains of Newcastle disease virus form plaques on chicken embryo lung monolayers in 48 to 72 h.

Quantitation of soluble residual host protein in chicken embryo-derived vaccines was performed rapidly, economically, and accurately by radial immunodiffusion.

Studies aimed at producing stronger birds and with better growth performance are being developed involving artificial incubation. To that extent, thermal stimulation by the heat of 1.39 oC and 1oC above the standard, and by cold of 36 °C fixed, were applied in the last week of the embryonic development (day 14 to day 18) to Cobb strain birds of 33 to 53 weeks age. With the purpose of evaluating...

Alternative models of microbial infections are increasingly used to screen virulence determinants of pathogens. In this study, we investigated the pathogenesis of Candida albicans and C. glabrata infections in chicken embryos infected via the chorio-allantoic membrane (CAM) and analyzed the virulence of deletion mutants. The developing immune system of the host significantly influenced suscepti...

Nowadays antibiotics are used on a large scale in veterinary and human medicine to cure or prevent diseases. Some antibiotics injected into hatching eggs to eliminate pathogens and prevention of egg transmission of disease. Adverse effects of drugs have always been a major concern. There is scantly information available about the safety and pathological alterations of lincosamide-aminocyclitol ...
