Example sentences for: pili
How can you use “pili” in a sentence? Here are some example sentences to help you improve your vocabulary:
Nontypeable H. influenzae strain M37 and an isogenic variant designated M37-1 which is deficient in expression of pili were kindly provided by Robert Munson [ 34 ] .
Strain M37-1 lacks expression of pili as indicated by absence of hemagglutination and absence of a 22 kDa band on SDS-PAGE corresponding to pilin [ 34 ] . In an experiment comparing biofilm formation in 4 duplicate wells, strain M37-1, the pilus deficient variant, yielded an average optical density of 0.204 whereas its isogenic parent strain, M37, yielded an average optical density of 0.884.
An isogenic variant of nontypeable H. influenzae deficient in expression in pili showed a marked reduction in the ability to grow as a biofilm.
In view of these lines of evidence suggesting that nontypeable H influenzae grows as a biofilm during human respiratory tract infection, the goals of the present study are to 1) Develop an assay to study biofilms of nontypeable H. influenzae in vitro; 2) Characterize the extent to which isolates from the middle ear fluid of children with otitis media and from the sputum of adults with COPD form biofilms; 3) Begin to elucidate the characteristics of the outer membrane antigens of nontypeable H. influenzae during growth as a biofilm; and 4) Preliminarily assess the role of pili in biofilm formation.
To assess the potential role of pili in biofilm formation, a variant of a strain of nontypeable H. influenzae which lacks expression of pili was tested for biofilm formation along with its isogenic parent strain.
