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...

ALBUQUERQUE, V. de A.; MEDEIROS, R. H. G.; PINHEIRO, R. R.; AZEVEDO, D. A. A. de; SOUSA, A. L. M. de; FACCIOLI-MARTINS, P. Y..
A Linfadenite Caseosa (LC) é uma doença de pequenos ruminantes causada por Corynebacterium pseudotuberculosis. O agente é resistente à fagocitose, replicando-se dentro de macrófagos e formando abscessos de difícil tratamento com antibióticos. Trabalhos têm avaliado nanopartículas como facilitadoras da entrega de fármacos em regiões não alcançadas convencionalmente. A Embrapa Gado de Leite tem desenvolvido nanopartículas de cloxacilina para tratamento de mastite por Staphylococcus e diante dos resultados obtidos, iniciou-se experimento piloto com sua utilização na LC. O objetivo foi avaliar a eficácia deste antibiótico no tratamento in vitro de macrófagos infectados com C. pseudotuberculosis.

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...

Bacteriophage: laboratorial diagnosis and phage therapy BJM
Silva,Joas L. Da; Hirata,Rosario D.C.; Hirata,Mario H..
Bacteriophages have been researched as a new alternative to antibiotics. These viruses inject their genetic material into bacteria and use their host machinery to multiply themselves. The research of bacteriophages in Brazil will certainly provide low-cost treatment of multidrug resistant bacteria, new microbiological diagnosis and advantages for the Brazilian food industry.

Brucella canis infection in dogs attended in veterinary clinics from patos, Paraíba state, Brazil BJM
Fernandes,Annielle Regina Fonseca; Azevedo,Sérgio Santos de; Piatti,Rosa Maria; Pinheiro,Eliana Scarcelli; Genovez,Margareth Élide; Azevedo,Adílio Santos de; Batista,Carolina de Sousa Américo; Alves,Clebert José.
To determine the frequency of anti-Brucella canis antibodies in dogs attended in veterinary clinics from Patos, Paraíba State, Brazil, as well as to identify risk factors and to isolate and identify the agent, 193 dogs were used. Agar gel immunodiffusion test (AGID) was used to detect B. canis antibodies in sera. Isolation of B. canis was carried out in blood and bone marrow from seropositive animals. Six animals tested seropositive in AGID, resulting in a frequency of 3.11%. B. canis was isolated from bone marrow of one seropositive animal, with confirmation by PCR. Lack of cleaning of the dog's environment was identified as risk factor (odds ratio = 7.91). This is the first report of isolation of B. canis in dogs from the Northeast region of Brazil.

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...

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...

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.

Abstract: This study aimed to determine the prevalence of ovine brucellosis in the states of Rio Grande do Norte, Paraíba, and Sergipe. A seroepidemiological survey was carried out in 121 properties under 23 municipalities between 2011 and 2012. The 1,034 serological samples collected from the sheep were subjected to the agar gel immunodiffusion (AGID) test using kits produced by the Paraná Institute of Technology (TECPAR). Anti-Brucella ovis antibodies were observed in 5.37% (70/1,304) of the animals evaluated, and the difference in the incidence of brucellosis between the adults and young animals of both sexes, and between the males and females was statistically significant (p < 0.05). The prevalence of brucellosis in Rio Grande do Norte, Paraíba, and...

Extended serotyping scheme for <i>Vibrio anguillarum</i> with the definition and characterization of seven provisional O-serogroups OMA
Pedersen, K.; Grisez, L.; van Houdt, R.; Tiainen, T.; Ollevier, F.P.; Larsen, J.L..
The present paper summarizes the serotyping scheme of the fish pathogenic bacterium <i>Vibrio anguillarum</i> and defines seven additional O-serogroups. Strains, collected in our laboratories that were nontypable with antisera against the previously defined 16 O-serotypes, were used for generating new antisera and were characterized further by means of LPS profiles, Western blots, and serological reactions. On the basis of the results, it is suggested that the seven new O-serogroups are to be included in the existing serotyping system as serotypes O17-O<sub>2</sub>3. However, the existence of further <i>V. anguillarum</i> strains that were not typable with any of the 23 O-antisera suggested the existence of additional...

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.

Resumo: A Clamidofilose é uma infecção bacteriana responsável por distúrbios reprodutivos em várias espécies, incluindo os ruminantes. Em ovinos, a infecção por Chlamydophila abortus é denominada como Aborto Enzoótico das Ovelhas e as consequências da infecção são infertilidade, abortos nas últimas semanas de gestação, ocorrência de natimortos e nascimento de cordeiros fracos. O agente pode ser transmitido de forma vertical ou horizontal e destaca-se pelo seu potencial zoonótico, envolvendo assim questões de saúde pública, além de ser uma importante causa de prejuízos econômicos. Desta forma, objetivou-se determinar a prevalência de ovinos soropositivos para Chlamydophila abortus através do teste de Elisa indireto em animais da mesorregião dos Sertões...

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...
