| production of heat-labile enterotoxin by strains of aeromonas veronii bv veronii. | three isolates of aeromonas veronii bv veronii (2 environmental, one blood infection) were examined to see if they produce any enterotoxin and, if so, to determine its characteristics. two isolates caused fluid accumulation in the initial rabbit ileal loop tests. the other strain did so after a single passage through the rabbit ileal loop. all the isolates showed gradual enhancement of fluid secretion after each subsequent passage. inocula of 1 x 10(4) viable cells and 0.25 ml of culture filtrat ... | 2000 | 11014770 |
| aeromonas veronii biovar veronii septicaemia and acute suppurative cholangitis in a patient with hepatitis b. | gram-negative bacilli of the genus aeromonas are widespread in aquatic environments and can be responsible for human infections. although aeromonas extraintestinal and systemic infections have been reported with growing frequency in recent years, aeromonas septicaemia remains an uncommon finding, often associated with serious underlying disease and predominantly related to the species aeromonas hydrophila, aeromonas veronii biovar sobria and aeromonas caviae. here, a case of a. veronii biovar ve ... | 2003 | 12867570 |
| [aeromonas associated with an acute diarrhea outbreak in são bento do una, pernambuco]. | an acute diarrhea outbreak, with 2170 cases, was described during january to july, 2004, in são bento do una, pernambuco. 582 stools were examined and an enteric pathogen was recovered in 25% (145 patients). aeromonas species were the most frequent (114-19.5%) and the main isolates were aeromonas caviae (57-9.8%), aeromonas veronii biovar sobria (23-3.9%), aeromonas veronii biovar veronii (15-2.6%) and other species (19-3.2%). the other isolated enteropathogens were vibrio cholerae o1-ogawa toxi ... | 2006 | 16699653 |
| cloning and expression of an outer membrane protein ompw of aeromonas hydrophila and study of its distribution in aeromonas spp. | the main aims of this study were to clone and express an outer membrane protein (omp), ompw, of aeromonas hydrophila and to study its distribution in aeromonas spp. | 2009 | 19426281 |
| clinical isolates of aeromonas veronii biovar veronii harbor a nonfunctional gene similar to the thermostable direct hemolysin-related hemolysin (trh) gene of vibrio parahaemolyticus. | thermostable direct hemolysin-related hemolysin encoded by the trh gene is considered a major virulence factor in the pathogenesis of vibrio parahaemolyticus infections. in this study, we report the presence of a trh homolog in three clinical isolates of aeromonas veronii biovar veronii. the presence of a trh homolog in these strains of a. veronii was confirmed by pcr, followed by cloning, sequencing and colony hybridization using a digoxigenin-labelled probe. dna sequence analysis revealed that ... | 2010 | 20636974 |
| complex evolutionary history of the aeromonas veronii group revealed by host interaction and dna sequence data. | aeromonas veronii biovar sobria, aeromonas veronii biovar veronii, and aeromonas allosaccharophila are a closely related group of organisms, the aeromonas veronii group, that inhabit a wide range of host animals as a symbiont or pathogen. in this study, the ability of various strains to colonize the medicinal leech as a model for beneficial symbiosis and to kill wax worm larvae as a model for virulence was determined. isolates cultured from the leech out-competed other strains in the leech model ... | 2011 | 21359176 |
| interaction of aeromonas strains with lactic acid bacteria via caco-2 cells. | the genus aeromonas includes some species that have now been identified as human pathogens of significant medical importance. we investigated the ability of 13 selected aeromonas strains belonging to nine species isolated from clinical cases (n = 5), environmental waters (n = 5), and fish (n = 3) to adhere to and translocate caco-2 cells in the absence and presence of two lactic acid bacteria (lab), i.e., lactobacillus acidophilus and bifidobacterium breve. aeromonas isolates were also assessed ... | 2014 | 24242240 |
| characterization of pathogenic aeromonas veronii bv. veronii associated with ulcerative syndrome from chinese longsnout catfish (leiocassis longirostris günther). | 273 bacterial strains were isolated from 20 chinese longsnout catfish samples. the biochemical characteristics of all strains conformed to the species description of aeromonas veronii bv. veronii on the basis of vitek gni+ card. furthermore, 16s rdna, gyrb and rpod sequences of the representative strain py50 were sequenced and showed high similarity with a. veronii bv. veronii in genbank. antibiotic-resistance of the representative strain py50 was assessed by the kirby-bauer disk diffusion metho ... | 2012 | 24031843 |
| first isolation and characterization of the pathogenic aeromonas veronii bv. veronii associated with ulcerative syndrome in the indigenous pelophylax ridibundus of al-ahsaa, saudi arabia. | virulent microbial pathogen infections are the main cause for amphibian decline worldwide. in the present study, a bacterial strain named rdl-2, which was isolated from the skin of infected pelophylax ridibundus larvae, was cultured and then phenotypically and biochemically characterized using scanning electron microscopic observations and the api20e strip and biolog gen iii microplate system. the 16s rrna gene sequence of this strain was also obtained and used in strain identification and phylo ... | 2017 | 29038059 |
| speciation, clinical profile & antibiotic resistance in aeromonas species isolated from cholera-like illnesses in a tertiary care hospital in north india. | aeromonas species have been reported to cause various illnesses in humans such as wound infections, septicaemia, peritonitis and pneumonia. their role in causation of cholera-like illness is also being increasingly recognized. this retrospective study was done to know the presence of aeromonas as a cause of acute diarrhoea in a tertiary care hospital and to find the common species of aeromonas causing diarrhoea and their antibiotic susceptibility patterns. | 2017 | 29205196 |
