Isotopic labeling of embryo, yolk sac, and intracellular parasites of the embryonated hen's egg by yolk replacement.

A technique is described which allows the replacement of 50% of the yolk of the embryonated hen's egg with large volumes of diverse but chemically defined solutions. By using an electrosurgical unit and a polyethylene tunnel, the procedure was performed on eggs from days 3 through 7 with greater than 90% surgical success and viability for the short term. More than 50% of the eggs replaced showe...

Recovery in embryonated chicken eggs of viable but non-culturable Salmonella

Salmonella paratyphi B and Salmonella typhimurium were starved in seawater microcosms respectively for 12 and 6 years. After starvation periods, major part of water was evaporated in each microcosm and salt crystals appeared. No culturable cells were obtained in selective and non-selective media. Salty suspension of each microcosm was inoculated in the yolk sacs of embryonated chicken eggs. Cul...

Recovery in embryonated eggs of viable but nonculturable Campylobacter jejuni cells and maintenance of ability to adhere to HeLa cells after resuscitation.

The existence of a viable but nonculturable (VBNC) state has been described for Campylobacter jejuni as it had been for a number pathogenic bacteria. Three C. jejuni human isolates were suspended in surface water and subsequently entered the VBNC state. After starvation for 30 days, VBNC cells were inoculated in the yolk sacs of embryonated eggs. Culturable cells were detected in a large propor...

Purification on renografin density gradients of Chlamydia trachomatis grown in the yolk sac of eggs.

Chlamydia trachomatis grown in the yolk sac of embryonated eggs was purified by centrifugation on continuous isopycnic Renografin density gradients. A band of chlamydial particles with a buoyant density of 1.20 contained 70% of the starting particles, and electron microscopy revealed the virtual absence of contaminating egg material. Centrifugation on Renografin gradients caused only a moderate...
