| Many algae species have been shown to have bactericidal or bacteriostatic substances (Glombitza, I979;Michaneck, 1979; Caccamese et al., 1980; Fenical & Paul, 1984; Niang& Hung, 1984). The antibacterialagents found in the algae include amino acids, terpenoids, phlorotannins, acrylic acid, phenoliccompounds, steroids, halogenated ketones and alkanes, cyclic polysulphides and fatty acids. In a large numberof marine algae antimicrobial activities are attributed to the presence of acrylic acid. |

| A carne de pescado é uma das mais susceptíveis ao processo de deterioração, devido a atividade de água elevada, composição química, teor de gordura insaturadas facilmente oxidáveis e pH próximo a neutralidade. O pescado pode atuar como veículo de microrganismos patogênicos para o homem, como as bactérias Staphylococcus coagulase positiva, coliformes, Salmonella spp, entre outros organismos mesófilos. O objetivo deste trabalho foi identificar a vida de prateleira do pintado conservado em gelo medindo o tempo de deterioração em função da contagem microbiológica de Staphylococcus coagulase positiva, Salmonella spp., coliformes termotolerantes (a 45°C) e contagem padrão de mesófilos aeróbios. The flesh of fish is one of the most susceptible to the process of... |

| Bacterial strains isolated from the kidney and liver of grey mullets, Mugil platanus Giinther, 1880, captured in Cananéia, São Paulo State, Brazil, in October 1996, belong to the genera Micrococcus, Pseudomonas, Flavobacterium, Aeromonas and Vibrio. The resistance/susceptibility patterns of the isolated micro-organisms to nine antimicrobial substances were determined, the more resistant bacteria had been Pseudomonas, Flavobacterium and Micrococcus. To the best of the authors knowledge this is the first bacteriological study done on Mugil platanus in Brazil. |

| This study presents some results of monitoring the beaches at East of Havana City, Cuba, during February and August corresponding to the rainy and less rainy seasons, respectively. For the bacteriological analysis were carried out 5 samplings in a period of 30 days, the rest of the samples was collected as punctual samples. The results are compared with those obtained in other samplings, specifically with 2004 period and with the requirements in the Cuban Standard NC: 22, (1999). Practically, the whole area showed pollution indicators deteriorated, such as: the permanganate oxidability value, bacteriological indicators and hydrocarbons, the last one corresponds to a lightly polluted area by hydrocarbons. The most affected areas were the outlet of the... |

| In order to maintain the high production and export rates achieved by the Brazilian poultry industry, it is necessary to prevent and control certain disease agents, such as Salmonella spp. Using bacterial cultures, the aim of the present study was to investigate the prevalence of Salmonella spp. in specimens collected from broiler facilities. Local wild birds were also sampled, as well as the feces of swine housed on the poultry farm. After sample collection, the isolated serotypes were subsequently inoculated into broiler chicks to determine their effects. Positive samples were collected from the following locations in the poultry facilities: poultry litter (S. serotype 4,5,12:R:-; S. Heidelberg; S. Infantis), broiler feces (S. Heidelberg; S. serotype... |

| The objective of this study was to isolate and characterize Streptococcus spp. in Nile tilapias (Oreochromis niloticus) reared in net-pens and earth nurseries. Eight intensive tilapia-rearing farms were investigated in north Paraná, Brazil from April 1st 2001 to April 30th 2002. The fish were reared in a system of hapas nets on four farms and in earth nurseries on other four farms. A total of 370 samples were analyzed of material collected from 120 fish (brain, liver, kidney, skin scrapes, ascites liquid and eye) that were sown on BHI agar (Brain Heart Infusion) supplemented with 1% yeast extract and sheep blood. Streptococcus spp. was isolated in 36 of the samples (18 brain, eight liver, eight kidney and two ascites liquid) from 25 fish. Streptococci were... |

| Transcription of nodulation genes in rhizobial species is orchestrated by the regulatory nodD gene. Rhizobium tropici strain CIAT 899 is an intriguing species in possessing features such as broad host range, high tolerance of abiotic stresses and, especially, by carrying the highest known number of nodD genes?five?and the greatest diversity of Nod factors (lipochitooligosaccharides, LCOs). Here we shed light on the roles of the multiple nodD genes of CIAT 899 by reporting, for the first time, results obtained with nodD3, nodD4 and nodD5 mutants. The three nodD mutants were built by insertion of ? interposon. Nod factors were purified and identified by LC-MS/MS analyses. In addition, nodD1 and nodC relative gene expressions were measured by quantitative... |

| Après avoir rapidement présenté le Bassin d'Arcachon et son environnement (situation géographique et réseau hydrologique), et rappelé quelques données sur l'ostréiculture, le tourisme et le réseau d'assainissement, le réseau de surveillance microbiologique (REMI) est décrit depuis sa mise en place en 1989 (réseau principal) jusqu'à son évolution en 1995 avec la mise en oeuvre d'un réseau étendu. Les résultats des analyses effectuées mensuellement sur les huîtres, au cours de ces sept années, sont présentés pour chaque station sous forme graphique, répartis en quatre secteurs géographiques. lls ont été interprétés pour chaque réseau en fonction des quatre zones de salubrité définis par l'arrêté relatif aux classements des zones de production, et, ensuite... |

| OBJECTIVE: Treatment of perianal abscesses requires prompt surgical drainage and antimicrobial therapy. However, we should encourage the selective use of antimicrobial agents on a case-by-case basis, especially because there is no evidence that uncomplicated perianal abscesses can be safely treated only with drainage. For this reason, it is important to identify the causative organisms; therefore, we accessed the microbiological analysis of these patients. PATIENTS AND METHODS: In this study, 81 consecutive adult patients with perianal abscesses, who presented at a university hospital in Diyarbakir from January 2004 to December 2006, were included. Clinical and laboratory data, and results of microbiological analysis were recorded. RESULTS: All specimens,... |
