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. |

Resumo: A Brucella ovis é um dos principais agentes etiológicos responsáveis por distúrbios reprodutivos em pequenos ruminantes, acometendo principalmente a espécie ovina, ocasionando prejuízos econômicos na cadeia produtiva. Este estudo teve como objetivo verificar a soroprevalência de ovinos e caprinos reagentes à Brucella ovis, através do teste ELISA, pertencentes aos rebanhos da agroindústria da carne no território da Bacia do Jacuípe, Bahia (BA), e na agroindústria do leite dos estados de Pernambuco (PE) e Paraíba (PB), além de avaliar os fatores de risco associados a infecção. Foram testadas 2.419 amostras séricas, e visitadas 112 propriedades, além da aplicação de questionários sobre o manejo do rebanho, visando associar as respostas à sorologia dos... |

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... |

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... |

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... |

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... |

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... |

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... |
