1. Virulence potential and antibiotic susceptibility pattern of motile aeromonads associated with freshwater ornamental fish culture systems: a possible threat to public health
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 throug

2. Florfenicol e biciclomicina: eficÃcia in vitro contra bactÃrias patogÃnicas de peixes de Ãgua doce. / In vitro efficacy of florfenicol e bicyclomycin to pathogenic bacteria from freshwater fish.
The Streptococcus agalactiae and the motile aeromonads are major pathogens for several tropical fish species, causing encephalitis and septicemia outbreaks, respectively, with high mortality in intensive culture systems. The use of antibiotic is the main control measure. The objective of this work was to determine the minimum inhibitory concentration (MIC) o

3. ConcentraÃÃo inibitÃria mÃnima de oxitetraciclina e Ãcido oxolÃnico frente Ãs aeromonas mÃveis na aqÃicultura. / Minimal inhibitory concentration of antibiotics used in aquaculture in face of Motile Aeromonads.
As bactÃrias do gÃnero Aeromonas sÃo microrganismos ubÃquos em ambientes aquÃticos, associadas a doenÃas em peixes e seres humanos. Bastonetes Gram-negativos pertencem à famÃlia Vibrionaceae e sÃo divididos em dois grupos e podem tambÃm servir de fonte de elementos genÃticos mÃveis carreadores de genes de resistÃncia a antibiÃticos. No Brasil,

4. Incidence, Distribution, and Spread of Tetracycline Resistance Determinants and Integron-Associated Antibiotic Resistance Genes among Motile Aeromonads from a Fish Farming Environment
A collection of 313 motile aeromonads isolated at Danish rainbow trout farms was analyzed to identify some of the genes involved in high levels of antimicrobial resistance found in a previous field trial (A. S. Schmidt, M. S. Bruun, I. Dalsgaard, K. Pedersen, and J. L. Larsen, Appl. Environ. Microbiol. 66:4908–4915, 2000), the predominant resistance phenot

5. The suicide phenomenon in motile aeromonads.
Certain strains of motile Aeromonas species, including all those of Aeromonas caviae examined, were shown to be suicidal. When they were grown in the presence of glucose at both 30 and 37 degrees C, there was rapid die-off of the organisms after 12 h of incubation, and viable cells generally could not be recovered after 24 h. It was shown that this phenomeno

6. Occurrence of Antimicrobial Resistance in Fish-Pathogenic and Environmental Bacteria Associated with Four Danish Rainbow Trout Farms
Surveillance of bacterial susceptibility to five antimicrobial agents was performed during a 1-year period in and around four freshwater fish farms situated along a stream in western Denmark. Besides assessing the levels of antibiotic resistance among the culturable fraction of microorganisms in fish, water, and sediment samples, two major fish pathogens (88

7. Hemolytic Activity and Siderophore Production in Different Aeromonas Species Isolated from Fish
The hemolytic activity and siderophore production of several strains of motile aeromonads were determined. The hemolytic activity of Aeromonas caviae and Aeromonas eucrenophila was enhanced after trypsinization of the samples. The enhancement of hemolysis was observed in strains that carried an aerolysin-like gene, detected by a PCR procedure. Siderophore pr

8. Aeromonas jandaei (formerly genospecies DNA group 9 A. sobria), a new sucrose-negative species isolated from clinical specimens.
A large numerical taxonomy study conducted in 1988 of 165 mostly clinical Aeromonas strains from diverse geographic sources produced a cluster (S = 84%, SSM) of four sucrose-negative strains that included the DNA definition strain for DNA group 9 A. sobria (CDC 0787-80). These four strains, together with five additional strains received in 1989, were subject
