Щодня щось дивовижне

Переважна більшість бактерій не спричиняє хвороб у людини

realistic AI-generated educational visualization of the inner surface of the large intestine with diverse bacteria; organisms illustrative and not to scale, not a microscopy photo. Created for fact 046 and reused here. Prompt: “Photorealistic educational cover image about the human gut microbiome. A medically plausible, respectful close-up visualization of the inner surface of the large intestine with a natural mucus layer and many tiny diverse bacteria attached and floating nearby, based on realistic scientific microscopy, warm soft tissue tones, bacteria shown as subtle small rods and spheres, no cartoon faces, no oversized organisms, no labels, no text, no gore, no diagrams, wide 3:2 landscape composition. Make it look like a high-quality scientific editorial photograph, with depth and clean lighting; organisms are illustrative and not to scale.” Visually checked 2026-10-21.

Здорова людина може носити бактерії, відомі як потенційні збудники, і водночас не мати від них хвороби. У проєкті NIH «Мікробіом людини» дослідники відібрали 242 здорових добровольців у США й зібрали понад 5 000 зразків із 15 ділянок тіла чоловіків і 18 ділянок тіла жінок. Вони аналізували ДНК безпосередньо в зразках, а не лише бактерії, які вдалося виростити в лабораторії. Це показує, що виявлення потенційного збудника ще не означає активної інфекції. Проєкт описував мікроби людського тіла, а не вимірював частку всіх бактерій на Землі, тому він не підтверджує точне число «1%».
