PARASITIC ORGANISM [6 records]

Record 1 2023-05-16

English

Subject field(s)
  • Microbiology and Parasitology
CONT

Foods with a parasitic bacterium, Bdellovibrio Bacteriovorus. The addition of B. bacteriovorus, an obligate parasite of gram-negative bacteria, to meats and meat products reduces the gram-negative population, lengthens the shelf-life, and reduces the risks of food-borne illness. The organism is intended to be applied to the surface of the food, onto food contact surfaces by spraying or dipping, or as part of a sanitizing rinse. It may also be used on uncooked seafoods and whole eggs. High parasitic activity occurs under aerobic conditions, near neutral pH, and at temperatures [greater or equal] to 20°C. Many pathogens are susceptible to attack by the parasitic organism.

OBS

parasitic bacteria: plural of "parasitic bacterium."

Record 3 2012-06-08

English

Subject field(s)
  • Genetics
CONT

Selfish genes are parasitic sequences of DNA that increase their own frequency in a population, usually to the detriment of the organisms that carry them. Although most genes can prosper only by contributing to the well-being of their bearers, there are certain times in the life cycle of an organism when genetic elements can potentially cheat and gain a transmission advantage.... Some genes cheat by inserting extra copies of themselves into cells; some cripple or obliterate their genetic counterparts on other chromosomes. A few can even change the sex of their host so that it produces only eggs or sperm favorable to the gene's distribution. Virtually all species, including humans, harbor at least some selfish genes.

French

Domaine(s)
  • Génétique
CONT

Dans la théorie du gène égoïste, on considère que l’unité de base des êtres vivants est le gène, ou une séquence génétique. La finalité du gène est de se multiplier. Pour se reproduire, il s’associe avec d’autres gènes d’une façon temporaire ou définitive, en fonction de son intérêt. [...] Certains gènes peuvent être en plusieurs copies dans un organisme. Certains peuvent aller se joindre à un organisme différent de celui dont ils sont issus. Un organisme peut être parasité par des gènes qui ne lui sont pas utiles, mais il peut aussi se débarrasser de gènes qui ne lui sont d’aucune utilité.

Spanish

Campo(s) temático(s)
  • Genética
CONT

[...] la teoría del "gen egoísta" afirma que los genes compiten entre sí para asegurarse la supremacía de unos sobre otros.

English

Subject field(s)
  • Crop Protection

DEF

A disease caused by living organism.

OBS

  • Sciences biologiques
OBS

Le potentiel de survivance correspond à l'adaptation d'une espèce à son milieu [...] il dépend de l'aptitude du ravageur à résister aux facteurs biotiques et abiotiques du milieu qui lui sont antagonistes.
