Mikoplazmaning ifloslanishi asosiy tadqiqot va sanoat ishlab chiqarishida tez-tez uchraydigan muammodir. Hujayra madaniyati yoki keng ko'lamli sanoat ishlab chiqarish uchun hujayra fabrikalari dan foydalanilganda, mikoplazmaning ifloslanishi ham juda muammoli. Xo'sh, bu holatda nima qilish kerak?
Mikoplazma mikroorganizm bo'lib, uning o'lchami bakteriya va virus o'rtasida (minimal diametr 0,2um) va mustaqil ravishda yashaydi. Mikoplazma hujayralarni ifloslantirgandan so'ng, madaniy muhit loyqa bo'lmasligi mumkin. O'tish va o'rta almashinuv orqali engillashtiriladi, shuning uchun uni e'tiborsiz qoldirish oson. Ammo ba'zi jiddiy holatlar hujayralar ko'payishning sekinlashishiga olib kelishi va hatto hujayra zavodidan tushib ketishi mumkin.
Agar mikoplazma bilan ifloslanish sodir bo'lsa, muhim bo'lmagan hujayralar uchun, masalan, madaniyat hujayralari, WCB hujayralari va boshqalar, kultura va ishlatilgan muhitni faolsizlantirish va tashlab yuborish mumkin. Muhimroq hujayralar uchun MRA davolash, dori yordamida isituvchi davolash, mikoplazmaga xos sarumdan foydalanish, hayvonlarda emlash va sterilizatsiya qilish, makrofag fagotsitozi va mikoplazmani tozalash vositasidan foydalanish davolash uchun ishlatilishi mumkin.
Mikoplazmaning oldini olish. kontaminatsiya hujayra madaniyati ishlari uchun hujayra zavodlaridan foydalanishning kalitidir. Mikoplazma bilan ifloslanish ehtimolini atrof-muhit ifloslanishini nazorat qilish, qat'iy eksperimental operatsiya, hujayra madaniyati muhiti va jihozlarining sterilligini ta'minlash va hujayra madaniyati muhitiga tegishli miqdorda antibiotiklar qo'shish orqali kamaytirish mumkin.
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.
