Bacteries ichtyopathogenes en mariculture ArchiMer
Vigneulle, Martine.
Bacterial infections occurred during the development of marine fish farming of species such as turbot, sea-bass, sea-bream or salmon and trout. The main-specific bacteria involved in these diseases observed belong to 3 groups: the Vibrionaceae for Vibrio anguillarum (type 408) and Aeromonas salmonicida , the causative agents of respectively vibriosis and furinculosis; the Corynebacteriaceae for Renibacterium salmoninarum , responsible for bacterial kidney disease (BKD), the Enterobacteriaceae for Yersinia ruckeri , the causative agent of enteric redmouth disease. The clinical signs typical of those diseases always depend on the rearing and environmental conditions. The losses resulting from these bacterial diseases and the persistence of the bacteria in...

Ecologie des vibrions pathogenes ArchiMer
Dodin, A; Dosso, M; Guillou, M.
There exists no biochemical test allowing to define the pathogenicity of a bacterium, still less for a Vibrionaceae. Two essential characters are to be retained to hold responsible an isolated germ, for an illness: 1) the binding factor, the identification is difficult but a double diffusion of agar should simplify the method; 2) the search for the choleric toxin or a common part of the choleric toxin (toxin LT or ST of E. coli ). Here again, simplified techniques may be used. The acquirement of a plasmid responsible for the binding factor or for the toxin production of the non-pathogenic Vibrionaceae in the origin of certain epidemic diseases in France and in the world. Frequently, epidemics due to common germs (Aeromonas hydrophila of Africa) lead to...

Reação de solanáceas à murcha bacteriana do tomateiro. Infoteca-e
SANTOS, J. R. M. dos; COLTRI, M. L..
Selecionaram-se solanaceas nativas imunes a murcha bacteriana do tomateiro, de modo a utiliza-las como porta-enxerto. Porem, so foi possivel adquirir-se sementes viaveis de quatro solanaceas rusticas. Com isso, resolveu-se avaliar cultivares e linhagens de tomate que vem sendo desenvolvidas para resistencia a murcha, alem de outras de habito determinado, as quais, em geral, apresentam-se mais resistentes a doenca. Dentre as treze solanaceas testadas, apenas o cubiu e a jurubeba vermelha mostraram-se imunes a murcha.

Ocorrência de abscesso hepático em caprinos. Repositório Alice
SANTA ROSA, J.; JOHNSON, E. H.; ALVES, F. S. F.; SANTOS, L. de F. L. dos..
Resumo: O exame necroscopico realizado em 658 caprinos demonstrou que 17 (2,5%) apresentaram abscesso hepatico. O exame bacteriologico do material purulento contido nos abcessos revelou o crescimento de Corynebacterium psudotuberculosis (58,89%), Escherichia coli (11,76%), Corynebacterium sp (11,76%), Pasteurella haemolytica (5,88%), Proteu sp. (5,88%) e Staphylococcus coagulase positiva (5,88%). Os abscessos hepaticos foram mais frequentes nos animais com mais de 13 meses de idade e foram produzidos, em sua maioria pelo, Corynebacterium pseudotuberculosis, agente da linfadenite caseosa dos caprinos. Os abscessos hepaticos quase sempre estavam associados com outras patologias tais como: broncopneumonias, linfadenite caseosa, parasitose gastrintestinal,...

Infectious pathology in mollusc and shrimp hatcheries ArchiMer
Mialhe, Eric.
Development of aquaculture has been linked to zootechnical mastering of larval production in hatcheries. Regular and excessive use of antibiotics (antifungal or antibacterial) may thus also be reduced, permitting to limit release of these products in sea-water and, consequently, avoiding progressive selection of resistant-strains.

The use of API 20E for the identification of <i>Vibrio anguillarum</i> and <i>V. ordalii</i> OMA
Grisez, L.; Ceusters, R.; Ollevier, F.P..
Sixty-eight strains of <i>Vibrio anguillarum</i>, five of <i>V. ordalii</i> and the type strains of <i>V. alginolyticus, V. carchariae, V. damsela</i> and <i>V. parahaemolyticus</i> were compared using the API 20E gallery. Within the <i>V. anguillarum</i> strains, distinct groups could be separated mainly on the basis of their reaction on indole production and the fermentation of amygdalin and arabinose. <i>Vibrio ordalii</i>, the former <i>V. anguillarum</i> biotope 2, could easily be separated from <i>V. anguillarum</i> and from the other fish pathogenic <i>Vibrio</i> spp.

Isolation and characterization of a pathogenic bacterium specific to Manila clam Tapes philippinarum larvae ArchiMer
Nicolas, Jean-louis; Ansquer, Dominique; Cochard, Jean-claude.
A bacterial strain belonging to the genus Vibrio was involved in a recurrent outbreak of disease in Manila clam Tapes philippinarum larvae at a commercial hatchery, This vibrio, named VTP for convenience, was not related to the known pathogenic vibrios and possessed unusual characteristics, Only Manila clam larvae and postlarvae were affected by the disease, Oyster and scallop larvae were not affected by vrp, Survival of vrp was found to be of short duration in seawater but even a very small number of cells (1 cell per 5 ml) could initiate the disease, VTP did not grow on thiosulfate-citratebile-sucrose agar and was resistant to chloramphenicol. An epidemiological study utilizing bioassays revealed the presence of VTP in adult bivalves and in the...

Jacq, E; Moal, Jeanne; Samain, Jean-francois; Corre, S; Daniel, J; Nicolas, Jean-louis; Cochard, Jean-claude; Fera, P.
Larval rearings were performed with seawater either freshly pumped or after storage in a pond. Concerning bacterial populations these waters were characterized by a high diversity, little sized bacteria whose few of them (1%) were cultivable on Zobell medium. In the tanks, the bacterial ecosystem was modified by the presence of antibiotics, larvae and algae: the diversity was lowered, the cellular volume was increased by a factor 2 to 5, 100% bacteria were cultivable and chloramphenicol resistant, and their metabolism changed. Taxonomic screening showed no differences among the two waters neither at the beginning nor at the end of the rearings. However, depending on the water (stored or not) differences were identified for bacterial physiology and...

An oral challenge for turbot larvae with <i>Vibrio anguillarum</i> OMA
Chair, M.; Dehasque, M.; Van Poucke, S.; Nelis, H.; Sorgeloos, P.; De Leenheer, A.P..
There is a need for a standard in vitro procedure to infect larval fish with bacteria. Such a procedure could be used as a tool to evaluate fish quality, verify fish sensitivity to a certain bacterial strain or evaluate the pathogenicity of a bacterium towards a given fish species. The availability of a challenge test is a prerequisite in studies dealing with the effect of different medicinal treatments on diseased fish. An oral challenge test would offer the possibility to investigate the routes of infection via the digestive tract, i.e. after feeding contaminated feeds. The present study aims to verify this hypothesis and proposes a standard challenge procedure for turbot (<i>Scophthalmus maximus</i>) larvae with a pathogenic <i>Vibrio...

Selection of bacteria enhancing the growth rate of axenically hatched rotifers (<i>Brachionus plicatilis</i>) OMA
Rombaut, G.; Dhert, P.; Vandenberghe, J.; Verschuere, L.; Sorgeloos, P.; Verstraete, W..
The effect of bacterial strains on the growth rate of rotifers, Brachionus plicatilis, was determined under monoxenic conditions. The first objective was to obtain sterile rotifer cultures starting from rotifer resting eggs using merthiolate or glutaraldehyde as disinfectant. Sterile rotifer cultures were obtained, without affecting the hatching ability of the resting eggs, when 0.05 µl/l glutaraldehyde was used. This disinfection procedure was used to examine the effect of 20 bacterial strains, isolated from well-performing live-feed production systems, on the population growth rate of rotifers cultured under monoxenic conditions. Five out of the 20 bacterial strains tested were able to improve significantly the asexual reproduction of rotifers. The...

L’étude des résistances vis-à-vis de différentes substances antibiotiques pour des espèces bactériennes (aérobies et anaérobies) isolées chez Mytilus galloprovincialis a été réalisée par la méthode standard de l’antibiogramme. Ainsi, 50 souches bactériennes aérobies et 20 souches anaérobies appartenant à plus de 25 espèces différentes ont été isolées et testées. Les résultats obtenus montrent des profils à plusieurs résistances vis-à-vis des différentes familles d’antibiotiques testés. Les résultats obtenus révèlent des profils à 12 résistances différentes notamment chez l’espèce anaérobie (Propioni acnes). Aussi, chez l’espèce aérobie pré dominante ( Aeromonas hydrophila) nous avons mis en évidence au moins 6 antibiotypes différents. Ces résultats...

Ensayos de fermentación de cultivo de bioyogurt, utilizando dos agentes neutralizantes OceanDocs
Cisneros, F.; Sedrés, J.M..
Se ensayó la fermentación para concentrados con cultivo de Bioyogurt, utilizando NaOH y CaCO3 como neutralizantes de la acidez, y se observó su efecto sobre la población final y la viabilidad. La fermentación se realizó en un medio semi- sintético. La solución de NaOH 4N se adicionó automáticamente durante el proceso para mantener el pH = 6,20 y el CaCO3 en polvo, se adicionó en porciones, según la variación de la acidez. Con ambas alternativas se obtuvo una población total final entre 1014 y 1016 UFC/mL, favorable para el proceso de preparación de concentrados bacterianos. Desde el punto de vista práctico, el uso del CaCO3 sólido presentó dificultades de manipulación y mayor riesgo de contaminación que el NaOH.
