Colonization of Lutzomyia verrucarum and Lutzomyia longipalpis Sand Flies (Diptera: Psychodidae) by Bartonella bacilliformis, the Etiologic Agent of Carrión’s Disease
Fig 6
L. longipalpis at 7d post-blood meal.
A small number of bacteria were observed (arrowheads) in the cibarium (CI), which is immediately connected to the proboscis and pharynx (PH) (A-B). Observation of B. bacilliformis in L. longipalpis tissues other than the abdominal midgut was rare, and samples of the non-competent vector continued to demonstrate digestion/disappearance of bacteria over time (C-F). Images acquired with fluorescence (GFP) or phase contrast (PC) microscopy at 400x magnification.
