Environmental Conditions Leading to Shellfish Contamination and Related Outbreaks
Provedor de dados: 5
Autores: Maalouf, Haifa; Pommepuy, Monique; Le Guyader, Soizick.
Human fecal wastes contain a large variety of viruses that can enter the environment through discharge of waste materials from infected individuals. Despite the high diversity of viruses that are introduced into the environment by human fecal pollution, only a few have been recognized to cause disease in association with consumption of contaminated shellfish. To explain bivalve mollusks contamination, several factors including human epidemiology, virus persistence through sewage treatment plant, and shellfish uptake may be suggested. Considering different outbreaks described in the literature, the most common route for transmission is accidental contamination after heavy rainfall, when extra loads cause an overflow, and release of untreated sewage into the...

Potential Impacts of Foodborne Illness Incidences on Market Movements and Prices of Fresh Produce in the U.S.
Provedor de dados: 31
Autores: Palma,   Marco A.; Ribera,   Luis A.; Bessler,   David A.; Paggi,   Mechel S.; Knutson,   Ronald D.
This study investigates the potential impacts of food safety outbreaks on domestic shipments, imports, and prices of the produce industry. Three case studies were analyzed to assess these potential impacts: the cantaloupe outbreak of March–April 2008, the spinach outbreak of September 2006, and the tomato outbreak of June–July 2008. Data-determined historical decompositions were conducted to provide a weekly picture of domestic shipment, import, and price fluctuation transmissions. The empirical analysis based on a vector autoregression (VAR) model showed differences in the results depending on the source of the outbreak (domestic vs. imported).

Hiding in plain sight: an evolutionary approach to the South American Zika outbreak and its future consequences
Provedor de dados: 103
Autores: Apari,Péter; Bajer,Katalin; Brooks,Daniel R.; Molnár,Orsolya.
ABSTRACT Emerging Infectious Diseases (EID) pose a world-wide health and socio-economic threat. Accelerating climate change and globalization are exposing unforeseen ways that pathogens cope with their surroundings. The 2015 Zika virus (ZIKV) outbreak was an example of expansion into previously inaccessible fitness spaces, causing a sudden epidemic. Recent studies indicating the subsequent decrease in symptomatic cases means the virus is in remission, currently poses little threat, and therefore can be ignored. We present an evolutionary scenario derived from the Stockholm Paradigm, of oscillating phases of expansion and isolation, accompanied by changes in transmission, persistence, virulence, and pathology. Chief among these is the likelihood that...

Temperature and foliage quality affect performance of the outbreak defoliator Ormiscodes amphimone (F.) (Lepidoptera: Saturniidae) in northwestern Patagonia, Argentina
Provedor de dados: 97
Autores: PARITSIS,JUAN; VEBLEN,THOMAS T.
In the temperate forests of Chile and Argentina the phytophagous moth Ormiscodes amphimone (F.) causes severe defoliation on the southern beech tree Nothofagus pumilio (Poepp. &amp;amp; Endl.) Krasser. The recent increase in defoliation frequency in some áreas appears to be influenced by a warmer climate. To evalúate the effects of temperature and the spatial heterogeneity of foliage quality on the performance and relative consumption rate of O. amphimone in northwestern Patagonia, Argentina we conducted a factorial experiment. Larval performance was measured as relative growth rate, developmental time, larval survival, and pupal weight. Larvae of O. amphimone were reared under two constant temperature regimes (15 °C and 20 °C) and fed with two N. pumilio...

Provedor de dados: 99
Autores: Mariottini,Yanina; De Wysiecki,María L.; Lange,Carlos E.
Los acridios figuran entre los invertebrados herbívoros dominantes en la mayoría de los sistemas de pastizal. Si bien, en Argentina, la importancia económica de estos insectos ha sido reconocida desde el siglo XIX, aún se desconocen aspectos importantes de la biología y ecología de la mayoría de las especies. El objetivo principal de este estudio fue determinar cómo la riqueza de especies, la composición y la densidad de acridios variaron en las comunidades vegetales más características del Sur de la provincia de Buenos Aires, durante cinco temporadas sucesivas (2005-06 hasta 2009-10), un área históricamente afectada por estos insectos. Se colectó un total de 22especies. La riqueza de acridios fue similar entre las diferentes comunidades vegetales,...

Will Mayaro virus be responsible for the next outbreak of an arthropod-borne virus in Brazil?
Provedor de dados: 55
Autores: Esposito,Danillo Lucas Alves; Fonseca,Benedito Antonio Lopes da.
Abstract Mayaro virus is an alphavirus from the Togaviridae family and is transmitted mainly by Hemagogus mosquitoes. This virus circulates in high-density tropical forests or rural areas of Central and South America causing a disease characterized by high-grade fever, maculopapular skin rash and marked arthralgia that, in some patients, can persist for long periods after infection and may be misinterpreted as chikungunya. Although only a few outbreaks involving this virus have been reported, in the last years the number of Mayaro virus infections has increased in the central and northern regions of Brazil. In this review, we describe the reported prevalence of this infection over the years and discuss the circumstances that can contribute to the...

Clinical signs, diagnosis, and case reports of Vaccinia virus infections
Provedor de dados: 55
Autores: Silva,Daniela Carla Medeiros; Moreira-Silva,Eduardo Augusto dos Santos; Gomes,Juliana de Assis Silva; Fonseca,Flávio Guimarães da; Correa-Oliveira,Rodrigo.
Vaccinia virus is responsible for a zoonosis that usually affects cattle and human beings in Brazil. The initial clinical signs of the infection are focal red skin areas, fever, and general symptoms similar to those of a cold. Then, pustules and ulcerated lesions surrounded by edema and erythema follow, as well as local lymphadenopathy that can last for weeks. Cure and healing of the lesions occur over several weeks, leaving a typical scar in the skin of people and animals affected. The infection definitive diagnosis is made through morphological characterization of the virus by use of electron microscopy, followed by PCR for specific viral genes. Since 1963, circulating orthopoxviruses in infectious outbreaks in several regions of Brazil have been...

Provedor de dados: 65
Autores: Kanitz,Fabio Adriano; Cargnelutti,Juliana Felipetto; Weiblen,Rudi; Batista,Helena Beatriz de Carvalho Ruthner; Flores,Eduardo Furtado.
ABSTRACT: This study investigated the suitability of virus isolation (VI) in mouse neuroblastoma cells (N2A) and baby hamster kidney cells (BHK-21) as a confirmatory test for diagnosis of bovine rabies. Fourty-eight brain samples from cattle suspected of rabies were initially submitted to fluorescent antibody test (FAT) and mouse inoculation test (MIT) for routine diagnostic. Subsequently, these specimens were submitted to three protocols of VI in each cell line: a single 24h or 72h passage (T1, T2), or three 48h passages (T3). The FAT and MIT combined detected 32/48 positive samples, from which MIT detected 32 and FAT 31. The average time required for final MIT results was 12.3 days (8 - 21). VI in BHK-21 cells provided definitive, positive results in...
