[Histological study of Ceratophyllus consimilis Wagn. fleas infected with the causative agent of listeriosis (Listeria monocytogenes)].
Histological studies have shown that in experimentally infected fleas (C. consimilis) Listeria are preserved in the alimentary canal. In infected individuals microbes occur along the whole intestine, from oesophagus to the rectum but most often they are recorded from the mid-gut and proventriculus. Listeria are able to penetrate into its muscular tissue and in some cases enter the body cavity of the insect. The finding of Listeria in the oesophagus confirms the possibility of the transmission of the infarction by fleas through the bite without blocking.
