Space Invader

Corte la cabeza del invasor.

The country fell into the invader's hand.

One never knows what disease will emerge in the system.

No invading army has ever set foot upon Japanese shores.

Introducing an innocuous version of a pathogen into the body causes the immune system to produce antibodies, which will neutralize the wild pathogen if it enters the body later.

Narrator A vaccine trains the body in advance how to recognize and neutralize a specific invader.

The virus that causes AIDS is the trickiest pathogen scientists have ever confronted.

BOURLANGES (PPE). (FR) I wish to make a personal statement.

This prevents a pathogen from escaping this part of immune response by mutation of a single molecular target.

The invading British army, laden with an immense network of supply wagons, invades Zululand and marches in the direction of Ulundi, the Zulu capital.

Russia, as an invading state, must stop cracking down on free speech in Crimea. CrimeaIsUkraine That's all I have to say.

So, if we have a population of a thousand people, and we want to make the population immune to a pathogen, we don't have to immunize every single person.

Then, calling a council of war, they immediately resigned to returning to their home territories, where they might better be able to engage Caesar's invading army.

Recently, however, effective methods for amplifying prions have been developed, which could enable detection of the pathogen before it can damage its host.

It is dated 30 November and was first adopted by the Prime Ministers' personal representatives.

It could depend on the nature of the pathogen different pathogens, using this technique, you'd get different warning or other phenomena that are spreading, or frankly, on the structure of the human network.

assist actively in the diagnosis of outbreaks of the relevant disease by receiving pathogen isolates for confirmatory diagnosis, characterisation and epizootic studies

The engineering approach simply says, Let's go and periodically repair all of these various types of damage not necessarily repair them completely, but repair them quite a lot, so that we keep the level of damage down below the threshold that must exist, that causes it to be pathogenic.

assist actively in the diagnosis of outbreaks of the relevant disease in Member States by receiving pathogen isolates for confirmatory diagnosis, characterisation and epizootic studies

One reason that there is no proven cure or vaccine for Ebola hemorrhagic fever is the wiliness of crossover diseases.

Vaccinating children against rotavirus, for example, can protect them from a pathogen that is responsible for 37 of all diarrhea deaths in children under five, thus saving 450,000 lives every year.

Around the turn of the century, the first sequencing of the human genome led to reverse vaccinology. This approach, whereby computational analysis of a pathogen s genome enables identification and screening of a great many more potential vaccine targets than was previously possible, was used in the successful development of a vaccine against meningitis B.

Hepatitis viruses are transmitted in two main forms, depending on the type of the pathogens hepatitis A and E travel through the alimentary tract (for example with infected food or water), hepatitis B, C, D and the other viruses are carried in blood and body fluids (semen, vaginal mucus, saliva).

And what we're seeing is not just the potential death of the Eastern Hemlock species that is to say, its extinction from nature due to this invading parasite but we're also seeing the death of an incredibly complex ecosystem for which these trees are merely the substrate for the aerial labyrinth of the sky that exists in their crowns.
