Non-invasive imaging of fluorescence-labeled bacterial distributions in aquatic species.

imaging is becoming an advanced tool for noninvasive distribution of longitudinal small animals. However, the aquatic species have been limited to the optical imaging of noninvasively tracking on pathogen distribution. The purpose of this study was to develop shell-less fish and shrimp models of non-invasive imaging technique for visualization of pathogens. This experiment was utilized , labeled with fluorescence probes to imaging bacterial distributions by IVIS Lumina LT system. The study was traced the internal distribution of fluorescence probes labeled bacteria in systemic organs by quantified their fluorescence intensities. The organ images were showed more obvious fluorescent signal in catfish intestine, liver, heart, kidney and the shrimp showed heart, hepatopancreas, and colon. Hence, the imaging methods using fluorescent labeled bacterial distribution were suggested to quantify by fluorescence intensity in whole pre-infected subjects. Therefore, it can offer the information about the localization and distribution of pathogens in the preclinical research, after immersion and injections.
