Abstract
AIM: To introduce a method for culturing nanobacteria from human gallbladder bile.
METHODS: The bile samples were collected from 30 patients with gallbladder-stone. After pretreatment with dilution-centrifuge-filtration (DCF) and filtration method, respectively, those samples were cultured under the ro-utine cell culture condition for nanobacteria. The morp-hological features of the obtained nanobacteria were observed under light and electron microscope. Indirect immunofluorescence staining was used to identify the nanobacteria.
RESULTS: Of the 30 bile samples, the positive rate of nanobacteria was 40% when the samples were pre-treated by DCF method, and the positive rate was 57% when they were pretreated by filtration method. There was no significant difference between those two methods (χ2 = 1.669, P >0.05). Brown movement of the tiny nanobacteria was observed at 2 wk. At 4 wk, nanobacteria started to attach on the bottom of the cul-ture bottles. Specific combination of the obtained nan-obacteria with 8D10 antibodies was observed. The nanobacteria were ball- or stick-like with a length of 80-350 nm under electron microscope.
CONCLUSION: The infection of nanobacteria exists in the bile of gallbladder-stone patients. Filtration is a si-mple and effective method for the preparation of the gallbladder bile.
