Rickettsia felis can be maintained in cat fleas by vertical transmission for up to 12 generations without the benefit of an infected host. Horizontal transmission or the acquisition of R. felis by fleas feeding on cats or artificially infected meals were not demonstrated in this study. Horizontal transmission of R. felis by the ingestion of feces or eggs by flea larvae was not detected. We also...
Cattle are major reservoirs of the provisionally named influenza D virus, which is potentially involved in the bovine respiratory disease complex. Here, we conducted a serological survey for the influenza D virus in Japan, using archived bovine serum samples collected during 2010-2016 from several herds of apparently healthy cattle in various regions of the country. We found sero-positive cattl...
Lateral gene transfer (LGT) is one of the most important processes leading to prokaryotic genome innovation. LGT is typically associated with conjugative plasmids and bacteriophages, but recently, a new class of mobile DNA known as integrating and conjugative elements (ICE) was discovered, which is abundant and widespread among bacterial genomes. By studying at the single-cell level the behavio...
