Transmission between hosts is primarily vertical, taking place exclusively through the female germ line, although horizontal transmission has also been documented. The results of several studies indicate that\n                    <jats:named-content content-type=\"genus-species\">Wolbachia<\/jats:named-content>\n                    spp. can undergo transfer between somatic and germ line cells during nematode development and in adult flies. However, the mechanisms underlying horizontal cell-to-cell transfer remain largely unexplored. Here, we establish a tractable system for probing horizontal transfer of\n                    <jats:named-content content-type=\"genus-species\">Wolbachia<\/jats:named-content>\n                    cells between\n                    <jats:named-content content-type=\"genus-species\">Drosophila melanogaster<\/jats:named-content>\n                    cells in culture using fluorescence\n                    <jats:italic>in situ<\/jats:italic>\n                    hybridization (FISH). First, we show that horizontal transfer is independent of cell-to-cell contact and can efficiently take place through the culture medium within hours. Further, we demonstrate that efficient transfer utilizes host cell phagocytic and clathrin\/dynamin-dependent endocytic machinery. Lastly, we provide evidence that this process is conserved between species, showing that horizontal transfer from mosquito to\n                    <jats:named-content content-type=\"genus-species\">Drosophila<\/jats:named-content>\n                    cells takes place in a similar fashion. Altogether, our results indicate that\n                    <jats:named-content content-type=\"genus-species\">Wolbachia<\/jats:named-content>\n                    utilizes host internalization machinery during infection, and this mechanism is conserved across insect species.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>IMPORTANCE<\/jats:bold>\n                    Our work has broad implications for the control and treatment of tropical diseases.\n                    <jats:named-content content-type=\"genus-species\">Wolbachia<\/jats:named-content>\n                    can confer resistance against a variety of human pathogens in mosquito vectors. Elucidating the mechanisms of horizontal transfer will be useful for efforts to more efficiently infect nonnatural insect hosts with\n                    <jats:named-content content-type=\"genus-species\">Wolbachia<\/jats:named-content>\n                    as a biological control agent. Further, as\n                    <jats:named-content content-type=\"genus-species\">Wolbachia<\/jats:named-content>\n                    is essential for the survival of filarial nematodes, understanding horizontal transfer might provide new approaches to treating human infections by targeting\n                    <jats:named-content content-type=\"genus-species\">Wolbachia<\/jats:named-content>\n                    .
