The catalase gene katA of the medicinal leech symbiont Aeromonas veronii bv. sobria was
cloned, sequenced, and functionally characterized. Southern hybridization, using an A …

Host-associated microbial communities are widespread in nature and vital to the health and
fitness of the host. Deciphering the physiology of the microbiome in vivo is critical to …

The gut bacteria of the North American medicinal leech, Macrobdella decora, were
characterized. Biochemical tests and DNA sequences indicated that Aeromonas jandaei is …

Most digestive tracts contain a complex consortium of beneficial microorganisms, making it
challenging to tease apart the molecular interactions between symbiont and host. The …

Culture-based studies of the microbial community within the gut of the medicinal leech have
typically been focused on various Aeromonas species, which were believed to be the sole …

Digestive-tract microbiota exert tremendous influence over host health. Host-symbiont model
systems are studied to investigate how symbioses are initiated and maintained, as well as to …

Transmission, critical to the establishment and persistence of host-associated microbiotas,
also exposes symbionts to new environmental conditions. With horizontal transmission …

The medicinal leech has established a long-term mutualistic association with Aeromonas
veronii, a versatile bacterium which can also display free-living waterborne and fish-or …

A fundamental feature of symbioses is the colonization of the host by specific
microorganisms. The degree of specificity is reflected both in the number of microbial …

Aeromonas veronii biovar sobria, Aeromonas veronii biovar veronii, and Aeromonas
allosaccharophila are a closely related group of organisms, the Aeromonas veronii Group …
