Directory of Open Access Journals Sweden. Full Text Available The aim of this study is to identify and monitor the presence of Aeromonas spp. We analyzed stool propiedaves from September to August Sixty-three patients were positive for Aeromonas spp. The most frequent symptoms were: Pediatric subjects were It is still controversial whether Aeromonas are responsible for human gastroenteritis, but their presence in faecies of symptomatic patients supports their etiologic role.

We propose search for toxins by polymerase chain reaction to identify strains that require an antibiotic therapy. Interlaboratorium vergelijking van het onderzoek naar Aeromonas spp.

Door middel van onderzoek van zes kunstmatig besmette gesimuleerde monsters drinkwater 4 Aeromonas spp. De tellingen in de deelnemende laboratoria. Incidence and virulence characteristics of Aeromonas spp. Full Text Available Aim: This study was conducted to evaluate the presence of Aeromonas spp. A total of samples of raw and RTE fish samples were taken from different fish markets and fish restaurants aeromona Assiut Governorate and screened for the presence of Aeromonas spp.

Plating unto the sterile Petri dishes containing Aeromonas agar base to which Aeromonas selective supplement was added. Presumptive Aeromonas colonies were biochemically confirmed and analyzed for pathogenicity by hemolysin production, protease, and lipase detection. The results indicated that raw fish were contaminated with Aeromonas spp. Regarding RTE, Aeromonas spp. Out of 35 isolates obtained, 22 were categorized as Aeromonas hydrophila, 12 were classified as Aeromonas sobria and Aeromonas caviae were found in only one isolate.

The virulence factors of Aeromonas spp. This study indicates that the presence of A. In dit rapport worden uitvoering en resultaten van een orienterend onderzoek naar het voorkomen van Aeromonas spp.

We aimed to investigate the distribution of Aeromonas spp. Between March and May wereanalyzed by membrane filter technique untreated water samples, collected from surface sources lakes, ponds andgroundwater wells drilled, captured springs, wells and chlorinated water that coming from local distribution network,located in rural areas of Moldova North-East Romania.

The information was processed and interpreted statisticallyusing EpiInfo aeromona.

The presence of Aeromonas spp. The results of this study confirms that untreated water used in rural areas can affect public health andmicrobiological indicators have predictive value for the presence of Aeromonas spp only reporting to surface sources. Prevalence and diversity of Aeromonas and Vibrio spp. The presence of Vibrionaceae on copepods was also investigated. Copepods were sampled at a station located inside the harbour of the city of Naples and were found contaminated by V.

aeromonas spp aisladas: Topics by

Full Text Available A total of 53 samples of products from animal origin and drinking water was examined for the presence of Aeromonas spp. Aeromonas occurred in The raw products showed high frequency of contamination and relatively high count Aeromonas hydrophila was the dominating species, None of the Aeromonas spp. Aeromonas ; animal origin products; drinking water. An investigation of the bactericidal activity of selected essential oils to Aeromonas spp.

Full Text Available Diseases of fishes caused by Aeromonas spp. Treatments of captive-reared populations using antimicrobials are limited with concerns for bacterial resistance development and environmental dissemination. This study was done to determine whether selected plant-derived essential oils were bactericidal to Aeromonas spp.

Initially, twelve essential oils were evaluated using a disk diffusion assay to an isolate of A. The greatest zones of inhibition were obtained with oils of cinnamon Cinnamomum cassia, oregano Origanum vulgare, lemongrass Cymbopogon citratus and thyme Thymus vulgaris.

The lowest mean MBCs 0. MBCs for three sources of oregano and lemongrass oils ranged from 0. Presence of Aeromonas spp in water from drinking-water- and wastewater-treatment plants in Mexico City. Samples were taken throughout a year by the Moore’s swab technique. The technique used for the isolation of the pathogen was suitable for samples with high associate microbiota content and for those with a scarce microbial content.

The presence of mesophilic-aerobic, coliform, and fecal-coliform organisms was investigated to determine whether there was any correlation with the presence of Aeromonas spp. Most samples from WWTP, which did not comply with the Mexican standards, had the pathogen, and some of the samples from the outflow of the DWP, which were within the limits set by the Mexican standards, also had Aeromonas spp.

Most samples containing Aeromonas spp.

Antibiotic resistance of potentially pathogenic Aeromonas strains [2008]

Full Text Available Aeromonas hydrophila and other members of Aeromonas genus are ubiquitus in aquatic environment and make part of normal bacterial flora of rainbow trout. Here we present our experience and knowledge on Aeromonas bacteremia, which causes mortality of rainbow trout fry. Rainbow trout fry, 7 month old, started to die in November Fish samples 17 samples of dead and moribund fish were delivered to the Laboratory for aquaculture. All of isolated and identified samples were tested for antibiotic susceptibility by disc diffusion method.

The test showed that specimens were most sensitive on flumequin, and relatively less sensitive on chloramphenicol and enrofloxacin. Resistencia antimicrobiana de Salmonella spp aislada de alimentos de origen animal para consumo humano. Full Text Available Objetivos.

Alpha-hemolytic toxin of Aeromonas hydrophila produced in vivo [in the muscle of carp]

Se excluyeron estudios realizados como parte de estudio de brotes o casos de infecciones en humanos. The predominant species was A. Population dynamics and antimicrobial susceptibility of Aeromonas spp. The main objective of this study was to quantify population and identify culturable species of Aeromonas in sediment and surface water collected along a salinity gradient in an urban estuary in Northeastern Brazil.

Thirty sediment samples and 30 water samples were collected from 3 sampling locations A, B and C between October and April Resistance to erythromycin was mostly plasmidial.

Door middel van kwantitatief onderzoek naar Aeromonas -bacterien in drie verschillende monsters water De Bilt, De Meent en De Laak werd een vergelijking gemaakt van de resultaten van Aeromonas onderzoek in 15 laboratoria in het kader van het deelproject: Chemotactic responses to gas oil of Halomonas spp.

  DYMO LABELMANAGER 210D MANUAL PDF

Full Text Available In this study, two halophilic bacterial strains isolated from saline habitats in Argentina grew in the presence of gas oil. They were identified as Halomonas spp.

Chemotaxis towards gas oil was observed in Halomonas spp. Las cepas aisladas se identificaron como Halomonas spp. En ensayos de swimming, las cepas del genero Halomonas spp. The occurrence of Aeromonas spp. Full Text Available The aim of this work was to study the occurrence of Aeromonas sp in the bottled mineral water, well water and tap water from the municipal supplies. Positive samples were found for Aeromonas spp. The recovery of Aeromonas spp. The occurrence of the Aeromonas spp.

However, a significant correlation was found between Aeromonas spp. The presence or absence of a correlation between the indicator bacteria and Aeromonas could reflect the occasional appearance of the pathogen in the drinking water and the different rates of survival and recovery of these agents compared with those fecal indicators. The finding that A porcentagem de amostras positivas para Aeromonas foi de O isolamento de Aeromonas spp.

Isolated from Urban Wastewater Treatment Plant. Full Text Available Members of the genus Aeromonas that commonly occur in various aquatic ecosystems are taken into account as vectors spreading antibiotic resistance genes ARGs in the environment. In our study strains of Aeromonas spp. There were no significant differences in number of identified ARGs between isolation points.

Characterization of antibiotic susceptibility was performed using disk the diffusion method with 12 different antibiotics according to CLSI guidelines. Finally, analysis of plasmid profiles among the resistant strains.
