| Emerging diseases pose a recurrent threat to bivalve aquaculture. Recently, massive mortality events in the Pacific oyster Crassostrea gigas associated with the detection of a microvariant of the ostreid herpesvirus 1 (OsHV-1 µVar) have been reported in Europe, Australia and New Zealand. Although the spread of disease is often viewed as a governance failure, we suggest that the development of protective measures for bivalve farming is presently held back by the lack of key scientific knowledge. In this paper, we explore the case for an integrated approach to study the management of bivalve disease, using OsHV-1 as a case study. Reconsidering the key issues by incorporating multidisciplinary science could provide a holistic under-standing of OsHV-1 and... |

| A large waterborne outbreak of infection that occurred during August 2000 in a local community in France was investigated initially via a rapid survey of visits to local physicians. A retrospective cohort study was then conducted on a random cluster sample of residents. Of 709 residents interviewed, 202 (28.5%) were definite cases (at least three liquid stools/day or vomiting) and 62 (8.7%) were probable cases (less than three liquid stools/day or abdominal pain). Those who had drunk tap water had a three-fold increased risk for illness (95% CI 2.4-4.0). The risk increased with the amount of water consumed (chi-square trend: p < 0.0001). Bacteriological analyses of stools were performed for 35 patients and virological analyses for 24 patients.... |

| Le naissain d’huître creuse Crassostrea gigas est touché chaque année depuis 2008 par des mortalités causées par un microvariant de l’ostreid herpesvirus 1 (OsHV-1 μVar). Plusieurs études montrent que ces évènements de mortalité se produisent préférentiellement lorsque la température de l’eau est comprise entre 16°C et 24°C. Par conséquent, une exposition rapide des huîtres infectées par OsHV-1 à des températures supérieures à 24°C pourrait limiter les mortalités causées par le virus. Il est proposé de (1) vérifier l’hypothèse selon laquelle l’exposition à haute température réduit la mortalité des huîtres infectées par OsHV-1, et (2) déterminer si les animaux qui ont survécu suite à l’infection par OsHV-1 et au traitement thermique sont... |

| This study (“Risco”), implicating both industry, socio-economic experts and biologists, was funded by the Regional Council of Brittany, for 3 years (2010-2013), to investigate upon the origin of oysters (Crassostrea gigas) mortalities in the bay of Quiberon (South Brittany, France). Specific mortalities of adult oysters were recorded in this bay in 2006, whereas mortalities of one year old spat were observed since in 2008 in this bay as at a national scale. The experimental protocol in 2010, including a monthly survey of oyster batches at 15 experimental stations, allowed to assess the risk for one-year oysters, due to viral disease. A clear spatial distribution of this risk was evidenced, with a western area spared from contamination and mortality, and a... |

| Ciguatera poisoning (CP) results from the consumption of seafood contaminated with ciguatoxins (CTXs). This disease is highly prevalent in French Polynesia with several well-identified hotspots. Rapa Island, the southernmost inhabited island in the country, was reportedly free of CP until 2007. This study describes the integrated approach used to investigate the etiology of a fatal mass-poisoning outbreak that occurred in Rapa in 2009. Symptoms reported in patients were evocative of ciguatera. Several Gambierdiscus field samples collected from benthic assemblages tested positive by the receptor binding assay (RBA). Additionally, the toxicity screening of ≈250 fish by RBA indicated ≈78% of fish could contain CTXs. The presence of CTXs in fish was confirmed... |

| Detection of an emerging disease is a crucial aspect for animal health. For the french marine mollusc aquaculture the interest is obvious, after three catastrophic epizooties. The methodological approach must be done by three different disciplines : epidemiology, ecology and marine pathology. Those three approachs are complementary in the special context of marine outbreaks. The uncertainty about many criteria and the lack of proofs feasible for showing the causality link, make the different approachs a necessity. The first step is the study of the three boxes, host, agent, environrnent. This approach, made for studying the cockles of the Croisic's bay could help us to make hypothesis about the possible origins ofmortality, and to a void measurement,... |

| Bonamia ostreae, an intrahemocytic protozoan parasite infecting the oyster Ostrea edulis, is responsible for an endemic disease affecting all intensive breeding areas of European countries. Epidemiological studies showed variable prevalences, 43% in Galicia (Spain), from 6% to 32% in France and 45% in the most important area of Ireland. The impact of oyster transfers, handlings, high densities have been implicated in the disease development but environmental stressors could be more involved than zootechnical methods. The effect of water temperature, salinity and tidal exposure were particulary examined to assess stress induced changes and determine physiological, biochemical and immunological state indices of oyster populations, which will contribute to... |

| Scorpion stings are a public health problem in the Maghreb region. In Algeria, epidemiological data were collected over the past twenty years by the Algerian health authorities. This study is an analysis of morbidity and mortality data collected from 2001 to 2010. Annual incidence and mortality due to scorpion envenoming were 152 ± 3.6 stings and 0.236 ± 0.041 deaths per 100,000 people (95% CI), respectively. The risk of being stung by a scorpion was dramatically higher in southern areas and central highlands due to environmental conditions. Incidence of envenoming was especially higher in the adult population, and among young males. In contrast, mortality was significantly higher among children under 15 years, particularly ages 1-4. Upper limbs were more... |

| Leptospirosis is a globally distributed emerging zoonosis. Dogs are commonly affected and although other serovars can cause canine leptospirosis, Leptospira interrogans serovar Canicola is primary found in these animals. A retrospective study was conducted using a database of 1195 dogs tested for Leptospira infection from 2003 to 2010 at the Laboratory of Zoonosis Diagnosis at the Veterinary Hospital of São Paulo State University (UNESP) in Botucatu, São Paulo state, Brazil. The seroprevalence of infected dogs was 20.08% (240/1195), and the most prevalent serovars were Canicola (6.7%), Copenhageni (5.0%), Icterohaemorrhagiae (2.9%), Autumnalis (2.9%), Pyrogenes (2.8%), Pomona (2.0%), Hardjo (2.0%), Australis (1.8%), Bratislava (1.6%), Cynopteri (1.4%),... |

| Bats are very interesting animals: they are the unique flying mammals, have developed a highly sophisticated echolocation system, and have become specialized to eat different types of diets. Hematophagous (vampire) bats are those specialized to feed solely on blood and have served as a source of inspiration for researchers as well as for writers. Vampire bat attacks on humans have moved from the realm of science fiction to reality in Latin America and bats (including non-hematophagous ones) have assumed an important role in the transmission of rabies virus to humans. This article discusses the emerging role of bats as rabies virus transmitters, with particular emphasis on the role of hematophagous bats in the epidemiology of human rabies in Latin America.... |

| Snakebite is a common occupational health hazard among Sri Lankan agricultural workers, particularly in the North Central Province. Viperine snakes, mainly Russell’s viper envenomation, frequently lead to acute renal failure. During the last two decades, an agrochemical nephropathy, a chronic tubulointerstitial disease has rapidly spread over this area leading to high morbidity and mortality. Most of the epidemiological characteristics of these two conditions overlap, increasing the chances of co-occurrence. Herein, we describe four representative cases of viperine snakebites leading to variable clinical presentations, in patients with chronic agrochemical nephropathy, including two patients presented with acute and delayed anuria. These cases suggest the... |

| Abstract Background Although considered a public health issue in Senegal, the actual incidence and mortality from snakebite are not known. In the present study, an epidemiological survey was carried out in Kédougou region, southeastern Senegal, where envenomations, particularly by Echisocellatus, are frequent and severe. Methods Three sources of data were used: records from health centers and reports by health professionals; traditional healers; and household surveys. Results The annual incidence and mortality provided by health centers were 24.4 envenomations and 0.24 deaths per 100,000 population, respectively. The annual incidence recorded by traditional healers was 250 bites per 100,000 inhabitants, but the number of deaths was unknown. Finally,... |

| The present study aims to elucidate the risk factors involved in deaths caused by scorpion envenomation. A retrospective study was carried out in the province of Kelâa des Sraghna from 2003 to 2004. The hospital charts of scorpion envenomation cases treated in the Essalama Hospital in Kelâa des Sraghna were exhaustively analyzed. Our study contains 31 cases of death among 470 hospitalization cases. Most stings had occurred during the hot period peaking in July and August (54.6%). Moreover, the scorpion stings occurred at night in 60.1% of the cases, between 6:00 pm and 6:00 am. In addition, all age groups were affected by envenomation, with a higher frequency in children aged less than 15 years (68.3%). The envenomation rate (class II + class III) was... |

| AbstractBackground The American trypanosomiasis is a zoonosis caused by the protozoaTrypanosoma cruzi (T. cruzi). The disease is widely distributed throughout the American continent, affecting a wide range of hosts, including dogs. It is present in the canine population in the State of Yucatan, Mexico. However, no significant studies in owned dogs have been performed in the metropolitan area of Merida. A transversal study was conducted in 370 owned dogs from Merida, Yucatan, Mexico.Methods A cross-sectional study including 370 dogs was performed in a major city of Yucatan, Mexico, to detect IgG antibodies against T. cruzi. A commercial ELISA test kit was used and a chi-square test used to evaluate associated risk factors; odds ratio (OR) and 95 %... |
