In our study, transmission potential was estimated from dissemination rates because previous studies have suggested that mosquitoes are capable of transmitting DENV as long as the virus is able to disseminate from the midgut into the hemocoel (i.
Its function may be related mainly to the transport of nutrients from the lumen into the hemocoel, secretion, endocytosis and exocytosis, and to increasing the resistance of the spermathecal epithelium filled with sperm (Gobin et al.
The microsphere suspension in saline was injected into the ventral hemocoel of the lobster through the thin cuticular membranes at the base of the pereiopods (walking legs) using a 22-gauge needle, with the total volume divided among several pereiopods.
When nymphal ticks feed, the bacteria pass through the hemocoel to the salivary glands and are transmitted to a new host in the saliva after 2 days.
The rectal pads are composed of 3 cell types: the columnar principal cells, which remain in contact with the gut lumen, and which are covered by a thin cuticle; the junctional cells, which are tall and narrow and which separate the principal cells of the epithelium of the rectum; and the basal cells, which are positioned below the principal cells, and which separate them from the hemocoel (Chapman 1998).
Although the Culex species tested were readily susceptible to oral infection, most infections were limited to the midgut and did not disseminate to the hemocoel.
Subsequent invasion of the hemocoel and draining of bodily fluids, nutrients, or occupancy of all available space results in the host's death (Lei et al.
Once the infective juveniles (IJs) gain access to the insect hemocoel, they release the symbiotic bacteria, which cause both a septicemia and a toxemia in the host.
In all the specimens that were fixed after their death (usually 2-5 d after fungal exposure) for histological preparation, the fungal hyphae quickly spread in the hemocoel, the muscles (Fig.
To administer the extract, sexually mature virgin females were anesthetized with nitrogen and 1 male equivalent of extract was injected into the hemocoel as in earlier studies on Diptera, deep to the lateral mesothorax through a pleuron.
