Immunolocalization of AVR-14 subunits in B. malayi mf by confocal laser scanning microscopy. (A) Bma-AVR-14 specific signal was detected in proximity to the ES apparatus. Counter staining with DAPI and Phalloidin-Rhodamine distinguishes major anatomical features (A, anus; ES, excretory-secretory apparatus; IB, inner body; M, mouth; NR, nerve ring). (B) A closer examination of the signal reveals colocalization of Bma-AVR-14 subunits with a muscle structure surrounding the ES vesicle (ESV).
