| Toxicity of seven emulsifying agents for treating oil spills (ISTPM designation E sub(22), E sub(30), E sub(41), E sub(46), E sub(47), E sub(52) and E sub(53)) was determined using eight marine species (three gastropods, one bivalve, two crustacean and one fish). Results are tabulated as LD sub(50). E sub(47) was least toxic to the species studied, but it could still perhaps harm other plant and animal species. |

| The slipper-limpet (Crepidula fornicata) is a marine gastropod which causes serious perturbations in shellfish beds, because of spatial spreading and density rising. Along French coasts, in Northern Brittany, two bays are highly colonized : bay of Saint-Brieuc, centre for scallops fishery, and bay of Mont-Saint-Michel, a famous oyster-farming area, with a total limpet stock about 450 000 metric tons. The association AREVAL was founded in 2001 to manage there, an industrial collect of limpets by a succing-dredge, followed ashore by a treatment for calcareous soil improvement. The scientific survey, contracted to IFREMER, included measurements of long andshort-term dredge's effects on grounds and limpet population, and proposals to set up dredging... |

| In European waters, significant economic damages to wooden structures are caused by bivalves molluscs and crustaceans. Treatments like copper-chrome-arsenic mixtures (CCA) were designed to prevent settlement of these wood borer species. However, limited and conflicting evidence regarding the toxicity to non-target organisms are available in the literature. This report aims to provide insights regarding the CCA leachates' toxicity to an important aquaculture species, the blue mussel Mytilus edulis for which much information on normal and stressed physiology is available for purposes of comparisons. The mussels are usually considered as a particularly suitable species for biological monitoring (Smaal and Widdows, 1994). To address the CCA leachate issue, two... |

| Fish culture (seabass, turbot...) on the French metropolitan coast, and shrimp culture in the overseas territories (essentially New Caledonia and Tahiti) are subject to a regular development through land based farms. Three thematic of research on aquaculture ponds are carried out in CREMA-L’Houmeau, in collaboration with producers. The aim of the first one is to determine the optimal rearing conditions (stocking density, water renewal rate, input of oxygen, rate of feeding...) which allow to minimise the quantity of wastes for a similar final biomass. The second part aims to reduce the nutrient loading in the effluent, through open-air treatments: sedimentation ponds, foam fractionation, mass production of phytoplankton, and rearing of molluscs on the... |

| NoV is highly infectious, and there is no threshold infectivity limit for NoV detected by PCR. The probability of becoming infected increases with the dose but depends also on the characteristics of the organism, the food matrix and the host factors. The relationship between the number of infectious virus particles and the number of virus genome copies detected by quantitative PCR is not a constant, and it is important to realise that the infectious risk associated with low level positive oysters as determined by real-time PCR may be overestimated. Quantitative data on viral load from areas compliant with current EU legislative requirements (E. coli standards) during January-March 2010 in 3 selected member states, show that a viral limit of 100, 200, 500,... |

| Pulsed light is a new method intended for the decontamination of food surfaces using short, high frequency pulses of an intense broad spectrum. The effects of broad spectrum pulsed light on the survival of Listeria monocytogenes Scott A, Listeria monocytogenes CNL, Pseudomonas fluorescens MF37 and Photobacterium phosphoreum SF680 populations on agar and in a liquid medium were investigated during this study. The sterilisation system generated 1.5 J cm(-2) per pulse with eight lamps for 300 mu s. In the case of surface-seeded cells, a 7.8, 8.14 and > 7.14 log reduction was obtained for L. monocytogenes, Ps. fluorescens MF37 and Ph. phosphoreum, respectively, after a single pulse of treatment. Inactivation levels were lower for depth-plated cells: indeed,... |

| The effects of experimental Trypanosoma congolense infection on the ejaculate of rabbits and changes caused after treatment with Diminaveto® were investigated using 24 New Zealand White rabbits (bucks). The bucks were housed singly in standard rabbit cages and fed on specialized ration containing 10% Protein supplement, grains, legume, salt and fresh water ad libitum during the study. Data on ejaculate characteristics were collected from all the bucks in the first phase (i.e. before infection) and in the second phase (i.e. during infection, with 4.8x10(5) Trypanosoma congolense, intraperitoneally). Similar data were collected from 12 randomly selected bucks treated with 7.0mg/kg Diminaveto® following reconstitution during the third phase. Data collected... |

| Envenomation caused by snakes of the Bothrops genus produces a lesion in the bite site and can result in extensive necrosis. The dead tissue can be secondarily infected by bacteria that come from the snake, and the bacteria can be inoculated at the moment of the bite. The bacteria that most commonly cause infection are the enterobacteria, mainly Morganella morganii, Proteus rettgeri, Enterobacter sp., and Escherichia coli. Group D streptococci including here Enterococcus sp. and the Bacteroides sp. are also involved. Based on a study of the sensibility of these bacteria, it has been suggested that this infection must be treated with chloramphenicol, as a sole antimicrobial agent, or with the combinations of benzylpenicillin or ampicillin with... |

| Abstract Background: Drug repurposing has been an interesting and cost-effective approach, especially for neglected diseases, such as Chagas disease. Methods: In this work, we studied the activity of the antidepressant drug sertraline against Trypanosoma cruzi trypomastigotes and intracellular amastigotes of the Y and Tulahuen strains, and investigated its action mode using cell biology and in silico approaches. Results: Sertraline demonstrated in vitro efficacy against intracellular amastigotes of both T. cruzi strains inside different host cells, including cardiomyocytes, with IC50 values between 1 to 10 μM, and activity against bloodstream trypomastigotes, with IC50 of 14 μM. Considering the mammalian cytotoxicity, the drug resulted in a selectivity... |

| Background In Guinea Elapids are responsible for 20% of envenomations. The associated case fatality rate (CFR) ranged 15-27%, irrespective of treatment. Results We studied 77 neurotoxic envenomations divided in 3 groups: a set of patients that received only traditional or symptomatic treatments, and two other groups that received either 2 or 4 initial vials of Antivipmyn® Africa renewed as necessary. CFR was 27.3%, 15.4% and 17.6%, respectively. Although antivenom treatment was likely to reduce CFR, it didn’t seem to have an obvious clinical benefit for the patients, suggesting a low treatment efficacy. Mean delay to treatment or clinical stages were not significantly different between the patients who recovered and the patients who died, or between... |

| Scorpion stings are a public health problem in Morocco, especially among children, who experience the most severe cases. Epidemiological and clinical findings on scorpion stings in Fez, Morocco, were evaluated in this investigation. Of 163 cases that required medical attention, 62.6% were male children. The mean age of patients was 4.8 ± 3.4 years. The mean time between stings and first medical attention was 3.36 ± 2.5 hours. Almost all cases occurred in the summer (94%) and extremities represented the most frequent sting sites (86.5%). Local pain, hyperemia, scarification, vomiting, sweating, restlessness, tachycardia and tachypnea were the observed clinical symptoms. Regarding severity, 55.2% of patients belonged to class III, followed by class II... |

| The present work evaluated histopathological aspects in experimental envenomation of dogs with Crotalus durissus terrificus venom. Twenty-eight mixed breed adult dogs were divided into three groups of seven animals each: Group I - only venom; Group II - venom + 50ml antiophidic serum + fluid therapy; Group III - venom + 50ml antiophidic serum + fluid therapy + urine alkalization. Lyophilized venom of Crotalus durissus terrificus was reconstituted in saline solution and inoculated subcutaneously at the dose of 1mg/kg body weight. Three animals of each group were subjected to euthanasia, and their muscular tissue, brain, spleen, kidneys, heart, lungs, stomach, small and large intestines, and popliteal lymph node fragments were collected for histopathological... |

| Snakebite is an important medical emergency. Anti-snake venom along with supportive care is the only specific treatment. However, many people put their faith in non-registered medical practitioners. Where medical aid is available, lack of trained health personnel jeopardizes the situation. This retrospective study, the first of its kind, was aimed at studying the pre-hospital treatment as well as the behavior of patients bitten by snakes and referred to the Postgraduate Institute of Medical Education and Research, Chandigarh, India. A total of 88 cases that occurred between January 1997 and December 2001 were studied. Seventy patients received treatment prior to admission (the majority was treated by non-registered medical practitioners, registered medical... |

| Among the diseases of viral origin, rabies is unique in its distribution and range of victims since it can afflict all warm-blooded animals. The interaction between the virus and the host population has facilitated the survival of the disease. The rabies virus (RV) has not changed in any significant way and has been capable of taking advantage of conditions suited to the continuance of rabies. Infection by RV is invariably lethal in the absence of protective immune response which, however, can contribute to the pathogenesis of rabies. Proinflammatory cytokines might affect, directly or indirectly, the levels of neurotrophins, growth factors, neurotransmitters and neurotoxins in the brain by activating glia, neurons, and vascular and immune cells. Although... |
