“…Interestingly, 1.5% of the total sequences from Qiandeng River water can be classified as Acinetobacter based on pyrosequencing methods. This result supports observations based on traditional plating methods that Acinetobacter species are widespread in river water (Bouvet and Grimont, 1986;Bouvet and Joly-Guillou, 2000;Braun, 2009).…”

This study aimed to explore the diversity of river water Acinetobacter populations using culture-dependent and -independent methods. Pyrosequencing indicated that 1.5% of the total sequences from Qiandeng River water were classified as Acinetobacter. Twelve Acinetobacter strains were isolated from three different sampling sites of the Qiandeng River. Based on culture-dependent methods, A. johnsonii, A. lwoffii and A. guillouiae were the most abundantly represented Acinetobacter strains among the upper, middle and downstream populations of the river. Probing of three Acinetobacter-enriched 16S rRNA gene libraries with the Acinetobacter specific probe Act660F revealed 42 unique 16S rRNA gene sequences exhibiting a similarity of 94.9 99.9% with the known Acinetobacter strains. Among the uncultured Acinetobacter sequences, 50%, 58.3% and 68.8% of those obtained from upstream sampling site A, middle stream sampling site B and downstream sampling site C were phylogenetically located within Group I. This Group represented the most abundant strains of Acinetobacter populations in river water based on culture-independent methods. The results indicated that culture-independent methods provide more detailed information on the diversity of Acinetobacter populations than that based on culture-dependent methods. Therefore, the development of new and efficient isolation methods to identify uncultured Acinetobacter species is required.

“…Acinetobacter is considered to be widely distributed in nature including in soil, water, living organisms, and vegetables, as well as humans and animals (Bouvet and Grimont, 1986;Bouvet and Joly-Guillou, 2000;Braun, 2009). However, different species of the genus are generally associated with different habitats.…”

“…This further demonstrates the potential threat of A. johnsonii to cyprinids fish farming. Various virulence factors are involved in the pathogenicity of Acinetobacter, like adherence to epithelial cells, production of extracellular enzymes and toxins, as well as the ability to protect against phagocytosis (Braun, 2008). The pathogenicity of isolate BY3 could probably be associated with the production of these virulent factors.…”

Bacteriosis has caused significant economic losses in farmed blunt snout bream Megalobrama amblycephala. Only scarce information is available on Acinetobacter johnsonii as a possible causal agent in M. amblycephala. In this study, a virulent strain temporarily named BY3, was isolated from diseased bream, identified phenotypically and molecularly as A. johnsonii. Phylogenetic trees of 16S rRNA and gyrB gene sequences were constructed to examine the taxonomic position of isolate BY3 and compare it to other known isolates. When screened against a range of common veterinary antibiotics, isolate BY3 has not shown resistance to florfenicol, neomycin, and sulfisoxazole antibiotics in aquaculture. To the best of our knowledge, this is the first report of A. johnsonii infection in farmed blunt snout bream.

As from January 2010 The Israeli Journal of Aquaculture-Bamidgeh (IJA) will be published exclusively as an on-line Open Access (OA) quarterly accessible by all AquacultureHub (http://www.aquaculturehub.org) members and registered individuals and institutions. Please visit our website (http://siamb.org.il) for free registration form, further information and instructions. This transformation from a subscription printed version to an on-line OA journal, aims at supporting the concept that scientific peer-reviewed publications should be made available to all, including those with limited resources. The OA IJA does not enforce author or subscription fees and will endeavor to obtain alternative sources of income to support this policy for as long as possible.
