Bakterial kontaminatsiya hujayra fabrikalari dan hujayralarni, jumladan Escherichia coli, Staphylococcus albus, Pseudomonas va boshqalarni etishtirishda foydalanilganda umumiy ifloslanish manbai hisoblanadi. Agar hujayralar bakteriyalar bilan ifloslangan bo'lsa, nima qilish kerak?
ifloslanish: Bakterial ifloslanish boshqa ifloslanish manbalaridan farq qiladi. Hujayra zavodidagi hujayralar ifloslanganidan keyin uni aniqlash oson. Ko'pgina hollarda, madaniyat eritmasi qisqa vaqt ichida sarg'ayadi, bu ko'p miqdorda kislotali moddalar ishlab chiqarilishini ko'rsatadi va aniq loyqalik paydo bo'ladi; Madaniyat muhiti dastlab aralashtirilmadi, lekin biroz chayqalgach, ko'plab loyqa moddalar suzib ketdi. Teskari mikroskopda kuzatilganda ko‘rish mumkinki, o‘stiruvchi muhitda ko‘p miqdorda sharsimon zarrachalar suzib yuradi, ba’zan esa hujayra yuzasida va uning atrofida juda ko‘p miqdordagi bakteriyalar mavjud bo‘lib, hujayralar o‘sishdan to‘xtab, zaharlanish namoyon bo‘ladi. Zarur bo'lganda, bakteriya turini aniqlash uchun bo'yash uchun oz miqdorda madaniy muhit smetasini olish mumkin; agar ma'daniy muhitdagi ba'zi o'zgarishlar aniq bo'lmasa va kontaminatsiyaga shubha bo'lsa, bulon muhitiga oz miqdorda oziqlantiruvchi muhit ham qo'shilishi va aniqlash uchun 37 darajada ekish mumkin.
Ifloslanishni davolash: Bakterial ifloslanish aniqlangandan so'ng, zarba terapiya odatdagidan 5-10 barobar ko'p antibiotiklar bilan amalga oshirilishi mumkin va an'anaviy madaniyat muhiti 24-48 soatlik dori-darmonlardan keyin o'zgartirilishi mumkin. Bu usul erta ifloslanishda samarali. Agar u kech aniqlansa va kontaminatsiya jiddiy bo'lsa, hujayralarni tashlab yuborish tavsiya etiladi.
Bakteriyalar bilan ifloslanishning kaliti bu oldini olishdir. Hujayra zavodining madaniyat muhitiga antibiotiklar qo'shilishi oz miqdorda bakterial kontaminatsiyani oldini oladi va yo'q qiladi. Agar bir nechta hujayra madaniyati o'tkazilsa, hujayralararo infektsiyani oldini olish uchun apparatni qat'iy ravishda ajratish kerak.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
