Climate Variability Reveals Complex Events for Tularemia Dynamics in Man and Mammals
Provedor de dados: 7
Autores: Palo, Thomas R; Mid-Sweden University; Thomas.palo@miun.se.
Tularemia is caused by the bacterium Francisella tularensis, but the natural reservoir is unknown and environmental conditions for outbreaks in mammals and man are poorly understood. The present study analyzed the synchrony between the North Atlantic Oscillation (NAO) index, the number of human cases of tularemia reported in Sweden, and the density of hares. Climate variation at a lag of 2 yr explained as a single factor ~ 27% of the variation in the number of tularemia cases over time. A low NAO index, indicating cold winters, and low water flow in rivers during the coming summer were associated with high numbers of human cases of tularemia 2 yr later. The number of mountain hares was not related to NAO or to the number of cases of tularemia. The change...

Viroses de pequenos ruminantes.
Provedor de dados: 14
Autores: PINHEIRO, R. R.; CHAGAS, A. C. de S.; ANDRIOLI, A.; ALVES, F. S. F.
A produção de pequenos ruminantes domésticos é limitada por inúmeros problemas sanitários, ocasionados por diversas enfermidades, de diferentes etiologias, na maioria das vezes não diagnosticadas, nem controladas adequadamente, o que compromete o desempenho produtivo do rebanho. Dentre as enfermidades que acometem os caprinos e os ovinos, destacamse as doenças causadas por vírus, que constituem um dos principais entraves na exploração desse animais. A ocorrência de viroses é comum nos rebanhos caprinos e, em determinadas circunstâncias, são inevitáveis os prejuízos advindos pela introdução e disseminação dessas doenças no rebanho. O conhecimento das principais viroses, bem como suas interações com os hospedeiros, são fatores imprescindíveis para a...

Seleção do sêmen de reprodutores portadores do vírus da artrite encefalite caprina através da técnica de reação em cadeia da polimerase.
Provedor de dados: 14
Autores: ANDRIOLI, A.; GOUVEIA, A. M. G.; PINHEIRO, R. R.
A partir de 1976, importações de caprinos de raças exóticas, procedentes de vários países, buscaram a introdução de potencial genético leiteiro, tendo ocorrido também a efetiva introdução de agentes infecciosos no Brasil pela importação de caprinos sem adequados critérios sanitários, com consequente dispersão de doenças infecciosas entre os rebanhos nacionais, dentre elas a CAE - artrite encefalite caprina. Os avanços das técnicas de conservação de sêmen, aliados ao aumento da importância econ0mica da caprinocultura favorecem o seu intercâmbio nacional e internacional. Somando-se a isto, a inseminação artificial possibilita a concepção de um expressivo número de fêmeas, num curta intervalo de tempo, no entanto, pouco se sabe do risco da transição de...

Salinity influences disease-induced mortality of the oyster Crassostrea gigas and infectivity of the ostreid herpesvirus 1 (OsHV-1)
Provedor de dados: 5
Autores: Fuhrmann, Marine; Petton, Bruno; Quillien, Virgile; Faury, Nicole; Morga, Benjamin; Pernet, Fabrice.
Mortality of young Pacific oysters Crassostrea gigas associated with the ostreid herpesvirus 1 (OsHV-1) is occurring worldwide. Here, we examined for the first time the effect of salinity on OsHV-1 transmission and disease-related mortality of C. gigas, as well as salinity-related effects on the pathogen itself. To obtain donors for OsHV-1 transmission, we transferred laboratory-raised oysters to an estuary during a disease outbreak and then back to the laboratory. Oysters that tested OsHV-1 positive were placed in seawater tanks (35‰, 21°C). Water from these tanks was used to infect naïve oysters in 2 experimental setups: (1) oysters acclimated or non-acclimated to a salinity of 10, 15, 25 and 35‰ and (2) oysters acclimated to a salinity of 25‰; the...

Characterization of Vibrio isolated from Crassostrea gigas spat suffering summer mortality outbreaks (slides)
Provedor de dados: 5
Autores: Gay, Melanie; Renault, Tristan; Le Roux, Frédérique.
The pathogens related to summer mortality outbreaks are a herpes virus and two bacterial strains one belonging to Vibrio splendidus biovar II and the other to Vibrio splendidus spp. However, the feature pathogen/opportunist of these strains is still unknown. Several strains belonging to the genus Vibrio have been identified as pathogen for different mollusk species. In the context of the French program Morest, experiments of cohabitation have been used to demonstrate the potential presence of a transmissible infectious agent in batches of oysters suffering from summer mortality outbreaks. More than one hundred Vibrio strains have been isolated from these experiments. These strains have been phenotypically and genotypically characterized. Their virulence...

Bats and their role in human rabies epidemiology in the Americas
Provedor de dados: 80
Autores: Dantas-Torres,F.
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....

The life cycle of &lt;i&gt;Anguillicola crassus&lt;/i&gt;
Provedor de dados: 27
Autores: De Charleroy, D.; Grisez, L.; Thomas, K.; Belpaire, C.; Ollevier, F.P.
For some years now the parasitic swim bladder nematode &lt;i&gt;Anguillicola crassus&lt;/i&gt; of the European eel &lt;i&gt;Anguilla anguilla&lt;/i&gt; L., has been reported from several European countries. The entire life history of this parasite has recently been elucidated in our laboratory. Young larvae leave the swim bladder of the host via the pneumatic duct and reach the water through the digestive tract. They are ingested by small copepods (Cyclopoida), which act as intermediate hosts. Larvae remain in the hemocoel until the copepods are eaten by the final host, the European eel. Larvae penetrate through the intestinal wall and reach the swim bladder where they develop into adults. When infected copepods are eaten by other small fish, such as carp...

Selection of bacteria enhancing the growth rate of axenically hatched rotifers (&lt;i&gt;Brachionus plicatilis&lt;/i&gt;)
Provedor de dados: 27
Autores: Rombaut, G.; Dhert, P.; Vandenberghe, J.; Verschuere, L.; Sorgeloos, P.; Verstraete, W.
The effect of bacterial strains on the growth rate of rotifers, Brachionus plicatilis, was determined under monoxenic conditions. The first objective was to obtain sterile rotifer cultures starting from rotifer resting eggs using merthiolate or glutaraldehyde as disinfectant. Sterile rotifer cultures were obtained, without affecting the hatching ability of the resting eggs, when 0.05 µl/l glutaraldehyde was used. This disinfection procedure was used to examine the effect of 20 bacterial strains, isolated from well-performing live-feed production systems, on the population growth rate of rotifers cultured under monoxenic conditions. Five out of the 20 bacterial strains tested were able to improve significantly the asexual reproduction of rotifers. The...

Socioeconomic Determinants of Disease Transmission in Cambodia
Provedor de dados: 31
Autores: Deolalikar,   Anil B.; Laxminarayan,   Ramanan.
The process of acquiring an infection has two components: first, exposure through proximity to another infected individual, and second, transmission of the disease. Earlier studies of the socioeconomic factors that affect the probability of acquiring an illness assume uniform exposure to infected individuals and may therefore result in biased estimates. This paper develops an empirical model, consistent with epidemiological models of spread of infections, to estimate the impact of socioeconomic variables on the extent of disease transmission within villages in Cambodia. Data from the 1997 Cambodia Socioeconomic Survey are used in this analysis.

Autores: Castro,Mariana Monteiro de; Prezoto,Helba Helena Santos; Fernandes,Elisa Furtado; Bueno,Odair Correa; Prezoto,Fábio.
Ants inhabit several types of natural and urban habitats, where they successfully nest. In urban environments, the hospitals should be considered priority for studies, as ants pose risks to human health due to their pathogen carrying potential. We aimed at surveying the literature about studies on ants in hospital settings in Brazil in the past 20 years. We found 40 papers in 22 journals, the first one published in 1993. Among them, 26 papers assessed pathogenic microorganisms on ants. We recorded 59 ant species, being Tapinoma melanocephalumthe most common. The Minas Gerais and São Paulo states had the largest number of published papers. Mato Grosso do Sul and Rio Grande do Sul showed the highest number of species. Exotic ant species were recorded in all...

Design and validation of a mobile air filter testing laboratory for animal agricultural applications
Provedor de dados: 111
Autores: Smith, Benjamin; Ramirez, Brett; Hoff, Steven; Harmon, Jay; Stinn, John.
The US swine industry is shifting towards filtered fresh-air ventilation systems that use pleated filters to improve breeding herd health and reduce airborne disease outbreak frequency. Loaded filters reduce airflow causing a poor environment and elevated energy use. Typical axial fans cannot efficiently maintain the rated differential pressure (DP; 100 Pa) for pleated filters; hence, a lower design filter DP (37 Pa) is used and consequently, more filters are required to achieve design maximum ventilation. Large, common filter banks for multiple staged fans presents significant challenges in using continuous DP measurement to assess filter life, making it impossible to separate filter loading DP from overall airflow DP. A mobile air filter testing (MAFT)...

A study of risk factors associated with the prevalence of Cryptosporidium in villages around Lake Atitlan, Guatemala
Provedor de dados: 55
Autores: Laubach,H. E.; Bentley,C. Z.; Ginter,E. L.; Spalter,J. S.; Jensen,L. A.
Cryptosporidium parvum is an endemic, zoonotic coccidian parasitosis that is highly prevalent in third-world countries where waterborne fecal contamination of food and drink or person-to-person contact with oocysts are the most common methods of transmission of the enteric protozoan. This type of transmission of the parasite made the villages around Lake Atitlan, Guatemala a unique site to compare environmental risk factors with the level of Cryptosporidium infections in the local residents. The study was carried out in two villages, San Antonio Palopo and Santa Catarina Palopo, located in the highlands above the shores of the lake. Smears from stool specimens of patients with gastroenteritis were processed using Kinyoun's modified acid-fast stain and...

Provedor de dados: 55
Autores: Senise,J.F.; Palacios,R.; Tanno,Z.N.; Lunardi,L.; Waghabi,G.R.; Vaz,M.J.R.; Diaz,RS.; Castelo,A.
It is currently recommended that antiretroviral prophylaxis to prevent mother-to-child transmission (MTCT) of HIV be initiated at 14 weeks of gestation. However, the relevance of early-gestation HIV viral load level for intrauterine MTCT is unknown. The objective of this study was to determine the relationship between prenatal maternal viral load and intrauterine MTCT. Records of HIV-infected pregnant women in two centers in Brazil, from 1999 to 2004 were analyzed. Three pregnancy periods were considered: earlier than 14 weeks, 14 to 27 6/7 weeks, and 28 weeks of gestation or more. Peripartum HIV exposure was also computed. Maximum viral load in each period was the measure of HIV exposure. Four hundred fifty-seven HIV-infected pregnant women were...
