Cell Culture Bacterial Contamination

Postby Katt » Wed Mar 25, 2009 4:43 pm

My lab has frozen peripheral blood mononuclear leukocytes which are contaminated by gram positive rods. These cells are extremely important and we are looking for a way to transform these cells into a B-Lymphoblastoid immortal cell line while at the same time getting rid of the gram positive rods. The source of this contamination is from the ficoll-hypaque used during blood processing. We have tried a 2 week pen/strep routine with poor results. Can anyone recommend an antibiotic regiment or strategy for eliminating this bacteria? Any help is greatly appreciated!

You could do an antibiotic susceptibility test to see which antibiotics will be effective. If you don’t have the where-with-all to perform such test, try a broad spectrum drug like tetracycline.
