چکیده
Ž . The purpose of this study was to find the minimum inhibitory concentrations MIC for the following antibacterial agents: chloramphenicol, florfenicol, flumequine and the combination Ž . trimethoprimrsulfadiazine to bacteria associated with scallop Pecten maximus larvae. To evaluate possible effects of components in seawater to the antimicrobial activity of these agents, MIC values were established on Mueller Hinton agar dissolved in either distilled water added 2% NaCl or 25‰ seawater. For flumequine and trimethoprimrsulfadiazine, the MIC values increased significantly using 25‰ seawater compared to 2% NaCl. Chloramphenicol and florfenicol did not show any significant increase in MIC values using 25‰ seawater compared to 2% NaCl. A significant increase in MIC values was found for chloramphenicol in the second egg group, using 25‰ seawater compared to 2% NaCl. It is concluded that flumequine, trimethoprimrsulfadiazine and chloramphenicol are, to a varying degree, antagonised by components in seawater. q 2000 Elsevier Science B.V. All rights reserved.

Complete Genome Sequence of Arcobacter sp. Strain LFT 1.7 Isolated from Great Scallop (Pecten maximus) Larvae
Arcobacter sp. strain LFT 1.7 was isolated from great scallop (Pecten maximus) larvae. Analysis of the 16S rRNA gene sequence showed that strain LFT 1.7 formed an independent lineage in the genus Arcobacter The draft genome of LFT 1.7 was sequenced to determine the taxonomic position and ecological function of this strain.

The aim of this project was to evaluate the impact of probiotic (Phaeobacter gallaeciensis, X34 strain) treatment on the complete development (from veliger to metamorphosis) of Pecten maximus larvae in the context of a bacterial challenge and in conditions more representative of hatchery practices. To that effect, the present study was divided into two main steps. In the first, we used in vitro...
متن کاملVibrio pectenicida sp. nov., a pathogen of scallop (Pecten maximus) larvae.
Five strains were isolated from moribund scallop (Pecten maximus) larvae over 5 years (1990-1995) during outbreaks of disease in a hatchery (Argenton, Brittany, France). Their pathogenic activity on scallop larvae was previously demonstrated by experimental exposure. The phenotypic and genotypic features of the strains were identical. The G + C content of the strains was in the range 39-41 mol%...

Hemocytes from two adult bivalves, Pecten maximus and Crassostrea gigas, were exposed to 12 different bacterial strains including 2 Alteromonas spp. (U1 and T413), 2 type strains of vibrios (V. anguillarum ATCC 19264 and V. alginolyticus ATCC 17749), 1 vibrio (S322) pathogenic to C. gigas larvae, 2 vibrios (V110 and V117) virulent to Ostrea edulis larvae, and 5 different strains of a same Vibri...
متن کاملDraft Genome Sequences of Neptuniibacter sp. Strains LFT 1.8 and ATR 1.1
We present the draft genomes of two strains previously identified as Neptuniibacter sp. LFT 1.8 (= CECT 8936 = DSM 100781) and ATR 1.1 (= CECT 8938 = DSM 100783) isolated from larvae of great scallops (Pecten maximus) and seawater, respectively. Both strains surely constitute two novel species in this genus, with putative applications for aromatic compound degradation.
