1. ovum.
2. oocyte.
3. a female reproductive cell at any stage before fertilization; after fertilization and fusion of the pronuclei it is called a zygote.

egg

(eg),
The female sexual cell, or gamete; after fertilization and fusion of the pronuclei it is a zygote; in humans the term egg is not used. In reptiles and birds, the egg is provided with a protective shell, membranes, albumin, and yolk for the nourishment of the embryo.

egg

The OVUM or female reproductive cell (GAMETE). The egg contains half the chromosomes required by the new individual, and the other half are supplied by the sperm at the moment of fertilization. The egg is a very large cell, about one tenth of a millimetre in diameter, and much larger than a sperm. This is because it contains nutritive material (yolk) to supply the embryo in its earliest stages before it can establish a supply from the mother via the placenta. If more than one egg is produced and fertilized, a multiple pregnancy results, but the offspring are not identical since half the chromosomes in each come from different sperms, with different genetic material. If a fertilized ovum divides, and each of the two halves forms a new individual, these will be identical twins, with identical chromosomes.

egg

  1. see OVUM.
  2. a structure produced by insects, birds and reptiles whose function is to enable embryonic development outside the female on land without the use of water as a growth medium. The vertebrate egg consists of an outer shell (hard in birds, leathery in reptiles), four types of embryonic membranes, a food supply in the yolk sac and surrounding albumen (‘egg white’) and the embryo which develops from an OVUM fertilized before the shell is deposited. Domestic birds can produce unfertilized eggs in which the embryo does not develop.

egg

1. an ovum; a female gamete.
2. an oocyte.
3. a female reproductive cell at any stage before fertilization and its derivatives after fertilization and even after some development.
4. hen egg, consisting of a blastodisk, remnant of the nucleus in a mass of white yolk sitting on top of the yellow yolk, the yolk suspended by two twisted strands of mucin-like protein, the chalazae, from the two poles of the egg, two yolk membranes that separate the yolk from the albumen, the albumen or white of the egg, which is in four separate layers of liquid and jelly material, two thin shell membranes and an eggshell. See also avian oogenesis.
5. helminth egg.

egg bound
a disease of cage birds, birds in zoological collections and in fish. In birds the hen may show pain and be straining and the egg may be palpable. The syndrome is comparable with dystocia in a viviparous animal. In fish the only sign is the wrinkled, shriveled eggs.
egg count
counting of helminth eggs as an estimate of the parasite status in the animal or group. Flotation techniques and special counting chambers are used. The results are expressed as eggs per gram (e.p.g) of feces.
egg dipping
dipping of hatchery eggs in antibiotic solutions, especially erythromycin or tylosin, to prevent the transmission of infections from adults to chickens.
egg drop syndrome
first observed in 1976 the disease is caused by an adenovirus and characterized by the hens laying a reduced number of thin-shelled or shell-less eggs. Subsequently the egg yield is reduced.
egg eating
a vice which begins without apparent reason. A high rate of egg breaking in the unit encourages birds to begin. Many techniques are used in prevention but frequent egg removal is essential.
grader egg
a reject from those destined for household use; used in petfood manufacture.
egg heating
heating eggs in a hot-air incubator for 12-14 hours to reduce the transmission of infection on the egg exterior.
egg peritonitis
see egg peritonitis.
egg retention
see egg bound (above).
egg shell
secreted around the egg mass and membranes during its last 15 hours in the uterus; composed of calcium carbonate and a glycoprotein matrix; surrounded by the cuticle.
thin-shelled egg
occurs in egg drop syndrome (see above), DDT poisoning. The shell of the egg is very thin, often missing altogether.
egg tooth
the additional tip to the beak in birds that is used by the hatching chick to peck out the circular hatch of shell to allow it to emerge. The egg tooth drops off in a few days. Called also bean.
egg transmission
transmission of disease from hen to chicken and between chickens via infection in the egg, e.g. Mycoplasma gallisepticum, M. meleagridis.
egg white injury
the effects of biotin deficiency induced by feeding of raw egg whites (albumen). The factor responsible is avidin which binds biotin, preventing absorption.
egg yield
in domestic fowl the normal annual average over a large, national population is about 130 eggs per bird; good units average 200.

Patient discussion about egg

Q. Is there any difference between brown eggs and white eggs? My fitness instructor suggested me to have brown eggs instead of white eggs so is there any difference between brown eggs and white eggs?

A. I have to agree with you. Never heard of any difference between the two and it doesnt sound reasonable that one is better to your health than the other...

Q. why the renal doctor told my husband that he needs to eat a dozen of egg a week for protein,how it will help? it won`t afect his cholesterol,also i would like to know what role the protein plays on his treatment and what other foot its rich in protein that he can can take,without causing problems to his health.

A. if i understand correctly, your husband is diabetic. like my grandfather he probably developed a "Diabetic nephropathy" which is a long name to: kidney being destroyed because of blood vessels clotted by diabetes. because of that destruction the kidneys allow protein to go out in the urine. this is a dangerous situation,a protein in the name of "albomin" helps our blood to hold fluids in blood vessels. without it fluid will leave the blood and go to our organs. not a good situation. so he needs a lot of proteins.
here is a list of a 100 protein rich foods:

Q. How can I catch Salmonella? Yesterday I ate a mousse which was made from raw eggs. Could I have caught Salmonella?

A. Salmonella infections usually resolve in 5-7 days and often do not require treatment unless the patient becomes severely dehydrated or the infection spreads from the intestines. Persons with severe diarrhea may require rehydration, often with intravenous fluids (IV). Antibiotics are not usually necessary unless the infection spreads from the intestines.

actual fecal egg counts in humans, dogs, cats, and pigs were multiplied by the estimated daily feces production, which was 160, 99, 20, and 1,516 g, respectively (21,26).

A quadratic relationship existed between faecal egg count loads and BCS whilst a negative linear relationship was observed between creatinine, cholesterol and albumin with faecal egg counts.
Somatostatin treatment over two days did not cause the total egg count per infected liver (8324 [+ or -] 6013) to be significantly reduced as compared to the egg counts in untreated mice at the acute stages of infection (7816 [+ or -] 5091), or even at the chronic stages of infection (31680 [+ or -] 12870 after treatment; 13640 [+ or -] 5580 without treatment) (Fig.
If the water were perfectly mixed, fish eggs would be distributed randomly and the catch ratio (between CalVET and CUFES) would be a constant, because egg count would be proportional to the volume of water filtered through the two samplers.
The preliminary fecal egg counts (FPEC) indicated that all the animals had a high infestation of parasites and the numbers of eggs within blocks and between blocks were similar (Table 4).
It is used routinely for worm egg counts in sheep, goats, deer, cattle, pigs, horses and other exotic species for both research projects and diagnostic samples.
With that information plus total egg counts, farmers could make a speedy decision on whether to spray.
The damage is done by immature larvae that are not producing eggs, so faecal egg counts are also not reliable.
Generally worms wouldn't be considered a problem in the winter but when the farm joined a EU-funded research programme, investigating the usefulness of faecal egg counts (FEC), a different picture began to emerge.
Until there are polymerase chain reaction probes for praziquantel resistance, the prevalence of genes for resistance to praziquantel could be estimated by giving two--or preferably three--treatments of praziquantel at monthly intervals and determining the reduction in egg counts after each round of treatment.
