Watch White Blood Cells Attack A Nematode Larva Take a look at a horde of white blood cells attacking a nematode larva. It's a time-lapse shot over the course of 80 minutes as eosinophils (a type of white blood cell) migrate towards the roundworm and release digestive enzymes that break it down. And if you thought that was interesting, take a look at this white blood cell literally chase a Staphylococcus aureus bacterium through a field of red blood cells.

Blog Tiếp Thị Liên Kết INFOGRAPHIE. Sida : comment le virus pénètre-t-il l'organisme ? SIDA. Transmis par le sang et les sécrétions sexuelles (ainsi que pendant la grossesse et l'allaitement), le virus de l'immunodéficience humaine (VIH) se multiplie dans l'organisme et entraîne, notamment, la destruction des Lymphocytes T, les cellules qui jouent un rôle central dans la coordination des défenses immunitaires. Lors de la transmission sexuelle, les muqueuses génitales sont les premières barrières rencontrées par le VIH (virus de l'immunodéficience humaine). Ces muqueuses sont constituées de cellules dendritiques et de macrophages qui constituent les premières cibles du virus. Ce dernier se transmet ensuite de cellules en cellules dont les lymphocytes T, cellules-cibles principales du VIH. Après plusieurs années, la personne infectée devient très vulnérable à certaines maladies dites "opportunistes" (certaines infections et tumeurs) contre lesquelles son immunité n'est plus suffisamment efficace. AUTOTESTS. Une maladie mieux prise en charge... et malheureusement banalisée

This colorful petri dish is full of bacteria, yeast and fungi that were found on her 8-year-old son’s hand after he finished playing outside. Sturm explained the process on Microbe World, where she posted the images. She used tryptic soy agar, which forms a nutritious jelly perfect for growing microbial cultures. The varying visible structures of these bacterial colonies reflect their microscopic characteristics. More info: microbeworld.org (h/t: colossal)
