Rickettsiae‐like structures in the larval salivary gland cells of Drosophila auraria

Abstract: Rickettsiae-like structures were found in the salivary gland cells of Drosophila auraria during different larval and prepupal developmental stages, from the early 3rd instar up to 14 hr after spiracle inversion. These microorganisms are surrounded by a membrane, are constantly intracellular, and occur singly or in groups. Their widespread occurrence in various tissues of other Drosophila species indicates that they can be considered as symbionts, but their actual functional significance (if any) is unknown.

“…The original one described, W. pipientis, was detected in the ovary of the mosquito Culex pipiens. Since then, RLOs have been reported in the salivary glands or Malpighian tubules of mosquitoes (19) and flies (20). However, popcorn is seen to widely proliferate in the brain, muscle, and retina of Drosophila and to cause tissue degeneration and early death of its adult host.…”

“…Other types of bacteria in various insect hosts have been documented in salivary glands and other tissues; these appear to be mostly cases of plant pathogenic bacteria within insect vectors, or bacteria manipulating reproduction. Examples include Spiroplasma and Phytoplasma plant pathogens (Fletcher et al, 1998;Kwon et al, 1999;Ammar and Hogenhout, 2005;Marzorati et al, 2006;Hogenhout et al, 2008), Wolbachia and Cardinium (Bacteroidetes) reproductive manipulators (Cheng and Aksoy, 1999;Mitsuhashi et al, 2002;Chen et al, 2005;Marzorati et al, 2006), and Rickettsiae-like organisms of unknown function (Thomopoulos et al, 1991). In tsetse flies, the secondary endosymbiont, Sodalis, but not the primary endosymbiont, Wigglesworthia, is found in salivary glands as well as other tissues (Cheng and Aksoy, 1999;Aksoy and Rio, 2005).…”

“…Το θερμικό shock δεν αλλάζει την ύπαρξη των Ricketchiae που φυσιολογικά υπάρχουν στις καλλιέργειες της D. auraria (Thomopoulos et al, 1991). Κάτω από όλες τις πειραματικές συνθήκες παρατηρήθηκαν ρικέτσιες (Ricketchiae), που τις περισσότερες φορές είναι κλεισμένες σε διπλή μεμβράνη και περιβάλλονται από μεμβράνη του ΑΕΔ.…”
