I don’t want anymore monkeys, thank you very much.
Animal testing: (I’m not really sure this is a question but I’ll explain a little bit about it) Can more or less be broken into two catagories. One is the mice/rat catagory. Use of mice and to a lesser degree rats is fairly common in lab experiments. Mice breed rapidly, are cheap to house and have a HIGH degree of similarity in their immune systems to humans.
Primates used in research are almost always used in the final stages of research. Primates are typically VERY expensive to purchase and after you purchase them you are required to pay for all vet care while the animal is being treated. I think most primates will cost 40K+vet/housing costs for the duration of the experiment.
Regardless of species, strict policies are in place before you can use an animal in an infection. Usually you have to have quite a lot of research justifying why you’d expect results from using the animal, then you have to get funding approval. Working with primates one of the stipulations is that once the animal shows visible signs of disease they must be euthanized, to prevent the animal from suffering. Animals treated with pathogens are kept in isolation, animals in a general population are housed as best as they can be given the facilities. (The primates where I work have drinking fountains, stuff to play on, lots of space and space heaters during the winter)
The VAST majority of animal research is researching being done on samples from the animals. I do a lot of work on white blood cells from macaque monkeys which I get from a 50mL blood sample drawn from one creature. There are regulations dictating the number of blood draws, age and weight of the creature. A lot of other tissue types are from necropsies (spelling?) which are tissue sections from dead animals.
As for the fear of cluster…
That’s … pretty strange. I’ve never heard of it or encountered it.
As for education. I have a B.A. in Biology. Most lab tech jobs require a BA in the appropriate field and around 2 years of lab experience. Most of that will be covered in lab courses you take for your major. Personally, I took all of the course work I could related to virology–microbiology, biochemistry, molecular biology, genetics, virology, oncogenetics, organic chemistry.
Generally however, as a starting lab tech you will be trained in all of the specific for the type of work you will be doing. Just a biology degree is required and some understanding of the basics. But the better prepaired you are, the faster you will pick up on things.
