Salmon farming industry in Chile currently uses a significant quantity of antimicrobials to control bacterial pathologies. The main aims this study were investigate the presence transferable sulfonamide- and trimethoprim-resistance genes, sul dfr, their association with integrons among bacteria associated Chilean salmon farming. For purpose, 91 Gram-negative strains resistant sulfisoxazole and/or trimethoprim recovered from various sources seven salmonid farms mainly identified as belonging...
The increasing market demand for cephalopods and the experiences obtained with different species has boosted interest in developing their culture Latin America. In 2008, an international workshop was held Puerto Montt, Chile, 14 experts experimental aquaculture from Brazil, Spain, Mexico. Several topics were approached within holobenthic Octopus maya merobenthic Enteroctopus megalocyathus, vulgaris, Robsonella fontaniana. Part of conclusions demonstrated that two greatest difficulties...
The taxonomic position of a chlorophenol-degrading bacterium, strain S37T, was investigated. 16S rDNA sequence indicated that this belongs to the genus Sphingopyxis, exhibiting high similarity sequences Sphingomonas alaskensis LMG 18877T (98.8%), Sphingopyxis macrogoltabida 17324T (98.2%), terrae IFO 15098T (95%) and adhaesiva GIFU 11458T (92%). These strains (except 15098T, which not investigated) novel isolate accumulated polyhydroxyalkanoates consisting 3-hydroxybutyric acid...
We evaluated the distribution and growth of Vibrio parahaemolyticus in inland sea southern Chile, where world's largest foodborne gastroenteritis outbreak by pandemic strain O3:K6 occurred 2005. Intertidal samples Mytilus chilensis Venus antiqua were collected around port towns between 41°28'S 43°07'S, during April to May 2011 January March 2012. used most probable number real-time polymerase chain reaction (MPN-PCR) for enumeration tlh, tdh, trh genes freshly harvested bivalves after a...
The culture of red cusk eel Genypterus chilensis is currently considered a priority for Chilean aquaculture but low larval survival rates have prompted the need continuous use antibacterials. main aim this study was to evaluate role live feed as source antibacterial-resistant bacteria in commercial G. chilensis. Samples rotifer and Artemia cultures used were collected during growth period culturable bacterial counts performed using spread plate method. Rotifer exhibited high levels resistant...
The early stages of culture the Chilean scallop Argopecten purpuratus are affected by mortality attributed to presence pathogenic bacteria. purpose this study was characterize culturable bacteria present in larval cultures A. and absence antibiotic (Tetracycline). Bacterial counts on marine agar from water, algal, samples units were carried out. These performed every three days during 20 incubation. bacterial strains isolated count plates identified 16S rDNA gene sequence analysis....

The mobility of perchlorate in soils depends on several factors, including soil mineralogy and the presence other oxyanions that compete with for retention sites. Currently, there are no studies evaluate arid soils. present study evaluated ClO4– three soils, Canchones, Humberstone Pica, exposed to two concentration ranges different ionic strengths. In (non-agricultural) Pica (agricultural) sorption processes were not important both ranges, while Canchones showed a decrease associated...
The main objective of this study was to characterize using whole-genome sequencing analysis, a new variant the qnrB gene (qnrB89) carried by fluoroquinolone-susceptible bacterium isolated from mucus farmed Salmo salar fingerling in Chile. Citrobacter gillenii FP75 identified biochemical tests and 16S ribosomal analysis. Nucleotide amino acid sequences qnrB89 exhibited an identity 81.24% 91.59%, respectively. genetic environment characterized upstream location sequence encoding for protein...
