Interaction of subminimal inhibitory concentrations of clindamycin and gram-negative aerobic organisms: effects on adhesion and polymorphonuclear leukocyte function. 1985

P E Lianou, and H P Bassaris, and E G Votta, and J T Papavassiliou

The effect of pre-incubation of Pseudomonas aeruginosa, Klebsiella pneumoniae and Proteus mirabilis with sub-inhibitory concentrations (sub MICs) of clindamycin on the adherence of these organisms was studied. Culturing these organisms in the presence of clindamycin (4 mg/l) resulted in significant enhancement of adherence for Ps. aeruginosa and Pr. mirabilis and decreased adherence for K. pneumoniae. Furthermore, the effect of pre-exposure to clindamycin on polymorphonuclear leukocyte (PMNLs) function against these organisms was determined. Filtrates of Pr. mirabilis pre-exposed to clindamycin promoted PMNL chemotaxis. No effect on chemotaxis was noted with the filtrates of clindamycin treated Ps. aeruginosa and K. pneumoniae. PMNL phagocytosis for all the organisms was increased after they were pre-exposed to clindamycin.

D006088	Gram-Negative Aerobic Bacteria	A large group of aerobic bacteria which show up as pink (negative) when treated by the gram-staining method. This is because the cell walls of gram-negative bacteria are low in peptidoglycan and thus have low affinity for violet stain and high affinity for the pink dye safranine.

D000268	Adhesiveness	A property of the surface of an object that makes it stick to another surface.	Adhesivenesses
