سويت search عن الفرق بين الـ pili و الـ fembriae ؟
وأبغى منكم تشوفوه صح أو خطأ أو ناقص ؟..
pili :..
These are hollow, hairlike structures made of protein allow bacteria to attach to other cells. A specialized pilus, the sex pilus, allows the transfer from one bacterial cell to another. Pili (sing., pilus) are also called fimbriae (sing., fimbria).
وفي بحث آخر لقيت ..
fimbriae and pili both are surface structure of bacteria but fimbriae are always found much in number having 3to25 nm diameter and 0.5 to 20 micrometer in length.
whereas pili are always found less in no generally 2 or more .
fimbriae are specialized for attachment of bacteria to its host as in case of pathogenic bacteria salmonella typhimurium , Nisseria gonorrhoea , bordella pertussis.
whereas pili are responsible for sexduction (conjugation) in bacteria ,and serves as receptors for certain viruses.
both fimbriae and pili are devided in many classes according to work they perform such as twiching motility of bacteria is observed in type 4 class..
besides these both are always noticed in gram (-) bacteria only exception cornibacterium renale (gram+).
أتمنى منكم تفيدوني ..
حتى لو حسيتوها معلومات سهلة
أنا مرة محتاجتها
