Oysters modify the planktonic microbial community structure by their filtration and NH4 excretion activities. While many studies have been conducted on this subject with adult oysters, none had been carried out in situ with juveniles. Pacific oyster juveniles (Magallana gigas, previously Crassostrea gigas) died massively all over the world since 2008 in relation with OsHV-1 infection. During mortality episodes, sick and dead oysters are not separated from healthy live ones, and left to decay in the surrounding environment, with unknown consequences for the nutrient cycle and planktonic microbial components (PMC). The present study aimed to elucidate for the first time the interactions between oyster juveniles and PMC during a mortality episode. Innovative... |

As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part 1: Beef Cow/Calf Herd Management Practices in the United States, were collected from beef producers September 29 through October 9, 1992. The National Agricultural Statistics Service (NASS) collaborated with VS to select a statistically designed producer sample that represented all U.S. cow/calf operations in the 48 continental United States. Eighty-one percent of operations had commercial cattle... |

Climate may affect broiler production, especially where there are heat waves, which may cause high mortality rates due to the heat stress. Heat wave prediction and characterization may allow early mitigation actions to be taken. Data Mining is one of the tools used for such a characterization, particularly when a large number of variables is involved. The objective of this study was to classify heat waves that promote broiler chicken mortality in poultry houses equipped with minimal environmental control. A single day of heat, a heat-shock day, is capable of producing high broiler mortality. In poultry houses equipped with fans and evaporative cooling, the characterization of heat waves affecting broiler mortality between 29 days of age and market age... |

The French oyster production is mainly based on the pacific oyster, Crassos/rea gigas. However, for several years, C. gigas spat has suffered severe mortality outbreaks. A multifactorial etiology implicating environment, oyster physiology, genetics and pathogens is heavily suspected. A herpesvims and bacteria belonging to the Vihrio s\p/endidus polyphyletic group have been isolated From summer mortality outbreaks. Moreover, several strains belonging to the genus Vibrio have been identified as pathogen for different mollusk species. However, few tools are available for the identification of these Vibrios and for the characterization of the virulence of the pathogenic strains. |

OBJECTIVE: To determine which available information at an Emergency Room (ER) consultation is associated with hospitalization or death among children with pneumonia. DESIGN: Prospective cohort study. SETTING: The ER of one university and one private hospital. MEASUREMENT: Using stepwise logistic regression we analyzed factors that showed a univariate association. MAIN RESULTS: Of 2,970 cases, the median age was 1.83 years (range 2 days to 14.5 yrs, mean 2.76 + 2.72 yrs); 25.8% were hospitalized and 0.8% died. Age (2-11 mos, OR 0.4 [0.2-0.6]; 12-59 mos, OR 0.2 [0.1-0.4]; <FONT FACE=Symbol>³</FONT> 5yrs, OR 0.1 [0.08-0.3]), malnutrition (OR 2.0 [1.4-2.7]), underlying chronic illness (OR 1.4 [1.1-1.8]), tachypnea (OR 1.8 [1.4-2.4]), chest... |

ABSTRACT The region around the municipality of Bastos, state of São Paulo, accounted for about 7% of Brazilian egg production in 2015. In 2012, it experienced a heat wave that resulted in the death of approximately 500,000 hens, according to information released at the time. Considering the impact of heat waves on layer mortality, the objective of this study was to analyze how heat waves impact the layer farming in the region of Bastos, considering the climate change scenarios forecasted by the IPCC for the next years. This study was conducted in three stages: i) analysis of the IPCC reports to understand climate change scenarios; ii) analysis of historical temperature data in the region of Bastos; iii) analysis of how climate change, through heat waves,... |

INTRODUCTION: leptospirosis is a zoonosis of worldwide importance. The disease is endemic in Brazil. This study was conducted to describe the clinical and laboratory presentation of leptospirosis in a metropolitan city of Brazil. METHODS: this is a retrospective study including 201 consecutive patients with leptospirosis admitted to tertiary hospitals in Fortaleza, Brazil, between 1985 and 2006. All patients had clinical and epidemiological data suggestive of leptospirosis, and positive laboratorial test for leptospirosis (microscopic agglutination test, MAT, higher than 1:800). RESULTS: a total of 201 patients were included, with mean age of 38.9 ± 15.7 years; 79.1% were male. The mean length from onset of symptoms to admission was 7 ± 3 days. The main... |

Los arrecifes coralinos del mundo han sufrido un declive durante las pasadas tres décadas. Estos cambios se han evaluado en arrecifes en franja; sin embargo, se desconoce si los tensores causantes de dichos cambios afectan la dinámica de una comunidad coralina en los primeros estados de la sucesión antes del desarrollo de un arrecife. Para resolver este interrogante, se monitoreó durante 2004, 2005 y 2006 una comuniddad coralina aislada en San Andrés. Se compararon temporalmente la abundancia, cobertura y mortalidad parcial sufrida por la comjnidad coralina y sus poblaciones de coral dominantes. La comunidad coralina no presentó variación estadística en riqueza, abundancia, cobertura, ni en área de mortalidad parcial. Sin embargo, esta comunidad si varió... |

Mussel samples have been placed in plastic-mesh bags hung on wood poles (« bouchots »), at 4 locations of a mussel culture area in the bay of Vilaine (South Brittany, France). They have been monitored for one year, from February 2000 to February 2001. The recorded growth have been rather fast (plus 1.2 g per month between April and September), and mortalities moderate (between 15% to 25%), with better results in southern stations, further from the estuary. Among the physico-chemical parameters recorded, the most striking were very low salinities (below 10 g/l) recorded for days, after heavy rains. They provoqued a valve closure of mussels (recorded by a « valvometer »). Some physiological indicators being tested (muscle force and hermeticity) seemed to... |

Summer mortalities of young oysters have been studied in 1999 through the monitoring of a unique oyster batch distributed among 3 sites located from upstream of an estuary (Fort-Espagnol, Auray river) to downstream (Kerpenhir, Auray river) up to open bay (Men er Roué, Bay of Quiberon). Mortality and growth have been monitered in parallel with vitality indices, so as to try or identify periods of weakness of oysters. The spat grew from a mean weight of 3 g, in the beginning of May to around 35 g in November, without sharp differences between sites. The summer mortalities remained moderate (10 %) in the 2 most marine stations, whereas a light peak of mortality (15 %) was recorded in July in the most continental station. Any of the physico-chemical parameters... |

BACKGROUND: Since healthcare-associated pneumonia (HCAP) is heterogeneous, clinical characteristics and outcomes are different from region to region. There can also be differences between HCAP patients hospitalized in secondary or tertiary hospitals. This study aimed to evaluate the clinical characteristics of HCAP patients admitted into secondary community hospitals. METHODS: This was a retrospective study conducted in patients with HCAP or community-acquired pneumonia (CAP) hospitalized in two secondary hospitals between March 2009 and January 2011. RESULTS: Of a total of 303 patients, 96 (31.7%) had HCAP. 42 patients (43.7%) resided in a nursing home or long-term care facility, 36 (37.5%) were hospitalized in an acute care hospital for > 2 days... |
