Aeromonas veronii strain B565 was isolated from aquaculture pond sediment in China. We present here the complete genome sequence of B565 and compare it with 2 published genome sequences of pathogenic strains in the Aeromonas genus. The result represents an independent stepwise acquisition of virulence factors of pathogenic strains in this genus.

Posttraumatic brain abscesses are usually caused by Gram-negative bacilli, notably Enterobacteriaceae and Staphylococcus aureus. Although Aeromonas hydrophila is a recognized cause of trauma-related sepsis, it has not been previously isolated from posttraumatic brain abscesses. We describe the first case of Aeromonas hydrophila brain abscess.

UNLABELLED INTRODUCTION Since the 1980s, leeches have been ingeniously used in the management of venous flap congestion. The presence of anticoagulative substances in their saliva improves the blood drainage. Their digestive tract contains several bacterial species, the main ones being Aeromonas hydrophila and Aeromonas veronii biovar sobria, which contribute to the digestion of ingested blo...

An acute infectious disease of northern sheatfish (Silurus soldatovi) was found in a commercial aquaculture pond Tianjin, China. Herein, two dominant bacterial strains were isolated from naturally diseased and identified as Aeromonas veronii Vibrio cholerae. Seven healthy seven fish that collected the used for gut microbiota analysis by high-throughput 16S rRNA gene sequencing. The α-diversity ...

Aeromonas hydrophila pc104A is a moderately virulent strain isolated from the soil of a catfish pond in west Alabama in 2010. Its full genome is 5,023,829 bp. The availability of this genome will allow comparative genomics to identify the virulence genes that are important for pathogenesis or immunogens for the purpose of vaccine development.

Aeromonas caviae is a Gram-negative, motile and rod-shaped facultative anaerobe that is increasingly being recognized as a cause of diarrhea in children. Here we present the first genome sequence of an A. caviae strain that was isolated as the sole pathogen from a child with profuse diarrhea.

Eleven strains of Aeromonas salmonicida were passaged twice by intraperitoneal injection through rainbow trout and reisolated from the kidney of moribund fish. The surface characteristics and virulence of the strains changed following passage through fish. None of the in vitro tests used could effectively predict the in vivo virulence.

A structural gene which codes for an extracellular protease in Aeromonas hydrophilia SO2/2 and D13 was cloned in Escherichia coli C600-1 by using pBR322 as a vector. The gene codes for a temperature-stable protease with a molecular mass of approximately 38,000 daltons. The protein was secreted to the periplasm of E. coli C600-1 and purified by osmotic shock. Cloned protease (P3) was identical i...

We performed microarray analyses of murine peritoneal macrophages to examine cellular transcriptional responses to a cytotoxic enterotoxin of Aeromonas hydrophila. While 66% of altered genes were common to both primary macrophages and the murine macrophage cell line RAW 264.7, Act caused expression changes of 28 genes specifically in murine peritoneal macrophages.
