BACKGROUND Two hundred and fifty volunteer patients attending 5 major hospitals in Nasarawa town, Nasarawa State, Nigeria were involved in this study to determine the prevalence of Aeromonas spp in persons with diarrhoea. The study population consisted of 133 males and 117 females between the ages of 0-70 years. METHODS Stool samples (148 diarrhoeal and 102 non-diarrhoeal) were analysed for t...
Aeromonas spp. are ubiquitous aquatic organisms, associated with multitude of diseases in several species of animals, including fishes and humans. In the present study, water samples from two ornamental fish culture systems were analyzed for the presence of Aeromonas. Nutrient agar was used for Aeromonas isolation, and colonies (60 No) were identified through biochemical characterization. Seven...
Aeromonas spp. were detected in samples collected from both untreated groundwater and treated drinking water in Lebanon. Aeromonas spp. levels ranged between 2 and 1,100 colonies per 100 ml in the intake underground well and between 3 and 43 colonies per 100 ml in samples from the distribution system. Samples positive for Aeromonas spp. from the network had a free chlorine level ranging between...
A bacterial agglutination assay, a toxin-neutralizing assay, and an enzyme-linked immunosorbent assay (ELISA) were used to compare antibodies against intestinal Aeromonas strains in serum samples from healthy carriers (n = 6), from patients with acute (n = 15) or chronic (n = 8) gastroenteritis, from patients with gastroenteritis caused by other enteropathogenic bacteria (n = 3), and from healt...
From October 1995 to February 1997, 13 isolates of Aeromonas species were recovered from four patients treated at National Taiwan University Hospital (Taipei). One of the patients, a diabetic, had simultaneous Aeromonas veronii biotype veronii bacteremia and A. veronii biotype sobria urinary tract infection. Seven weeks after the episode, the patient had necrotizing fasciitis due to A. veronii ...
Phenotypic characteristics were used to identify 189 Aeromonas strains isolated from human feces. One hundred forty-two of these strains were placed in 11 DNA hybridization groups, and the genetic and phenotypic data were compared. According to the criteria of Popoff, 66% of the strains were identified as Aeromonas caviae, 18% were identified as A. sobria, and 16% were identified as A. hydrophi...
Species of the genus Aeromonas, which inhabit aquatic environments, can produce septicaemia and ulcerative and hemorrhagic fish diseases, including furunculosis, which result in mass death and important economic losses in the aquaculture sector (Austin & Austin, 2007; Beaz-Hidalgo et al., 2010; Bernoth et al., 1997; Gudmundsdóttir & Björnsdóttir, 2007; Noga, 2010; Wiklund & Dalsgaard, 1998). Th...
Two types of flagella are responsible for motility in mesophilic Aeromonas strains. A polar unsheathed flagellum is expressed constitutively that allows the bacterium to swim in liquid environments and, in media where the polar flagellum is unable to propel the cell, Aeromonas express peritrichous lateral flagella. Recently, Southern blot analysis using a DNA probe based on the Aeromonas caviae...
We sequenced the genome of the high-melanin-yielding Aeromonas media strain WS and then analyzed genes potentially involved in melanin formation. The 4.2-Mb draft genome carries multiple genes responsible for pyomelanin synthesis and other candidate genes identified in our separate study, which have no homolog in other strains of Aeromonas species.
Although they are ubiquitous to aquatic environments, Aeromonas species have traditionally been considered nonvirulent; however, in the past 30 years, they have emerged as important human pathogens that can cause a wide spectrum of disease. In this study, we describe a case of recurrent Aeromonas bacteremia in an immunocompetent patient, and this exposure was linked to the patient's home well w...
