AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2013; 140-141:324-336. [PMID: 23891781 DOI: 10.1016/j.aquatox.2013.06.022] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2013] [Revised: 05/15/2013] [Accepted: 06/26/2013] [Indexed: 06/02/2023]
Abstract
The roles of consortia of phototrophic microorganisms have been investigated in this paper to determine their potential role to tolerate or resist metals and to capture them from polluted cultures. With this purpose, two consortia of microorganisms: on one hand, Geitlerinema sp. DE2011 (Ge) and Scenedesmus sp. DE2009 (Sc) (both identified in this paper by molecular biology methods) isolated from Ebro Delta microbial mats, and on the other, Spirulina sp. PCC 6313 (Sp) and Chroococcus sp. PCC 9106 (Ch), from Pasteur culture collection were polluted with copper and lead. In order to analyze the ability of these consortia to tolerate and capture metals, copper and lead were selected, because both have been detected in Ebro Delta microbial mats. The tolerance-resistance to copper and lead for both consortia was determined in vivo and at cellular level by Confocal Laser Scanning Microscopy (CLSM-λscan function). The results obtained demonstrate that both consortia are highly tolerant-resistant to lead and that the limits between the copper concentration having cytotoxic effect and that having an essential effect are very close in these microorganisms. The capacity of both consortia to capture extra- and intracellular copper and lead was determined by Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) respectively, coupled to an Energy Dispersive X-ray detector (EDX). The results showed that all the microorganisms assayed were able to capture copper extracellularly in the extrapolymeric substances, and lead extra- and intracellularly in polyphosphate inclusions. Moreover, the studied micro-organisms did not exert any inhibitory effect on each other's metal binding capacity. From the results obtained in this paper, it can be concluded that consortia of phototrophic microorganisms could play a very important role in biorepairing sediments polluted by metals, as a result of their ability to tolerate or resist high concentrations of metals and to bioaccumulate them, extra- and intracellulary.

Abstract
Microbial mats are coastal ecosystems that consist mainly of cyanobacteria, primary producers in these habitats that play an important role in stabilising delta sediments. However, these ecosystems are subject to various kinds of pollution, including metal contamination, placing their survival at risk. Among heavy metals, copper is an essential metal at low doses and toxic at high doses. This metal is present in different pesticides used in rice production, a thriving agro-industry in the Ebro Delta (Spain). For several years, our group has been studying the Ebro Delta microbial mats and has developed a method for determining the effect that metals cause on cyanobacteria populations. This method is based on confocal laser microscopy coupled to a spectrofluorometer, which rapidly provides simultaneous three-dimensional information on photosynthetic microorganisms and their fluorescence spectra profiles. The current study determines the copper effect on different photosynthetic microorganisms from culture collection (Chroococcus sp. PCC 9106 and Spirulina sp. PCC 6313) and isolated from the environment (Microcoleus-like and the microalga DE2009). Comparing all results obtained it can be observed that the minimum dose of Cu that is capable of significantly altering chlorophyll a (chl a) fluorescence intensity were 1 × 10(-7) M in Chroococcus sp. PCC 9106; 1 × 10(-7) M in Spirulina sp. PCC 6313; 3 × 10(-7) M in Microcoleus and 5 × 10(-6) M in the microalga DE2009. Moreover, the sensitivity of the technique used was 1 × 10(-7) M.

Abstract
Micrococcus luteus DE2008 has the ability to absorb lead and copper. The effect of these metals on biomass and viability of this microorganism were investigated and removal of the metals from culture media was determined. Lead had no effect on the biomass expressed as mg Carbon/cm(3) of M. Iuteus DE2008, but in the case of copper, the minimum metal concentration that affected the biomass was 0.1 mM Cu(II). According to these results this microorganism shows a greater tolerance for lead. The minimum metal concentration that affected viability (expressed as the percentage of live cells) was 0.5 mM for both metals. M. luteus DE2008 exhibited a specific removal capacity of 408 mg/g for copper and 1965 mg/g for lead. This microorganism has a greater ability to absorb Pb(II) than Cu(II). M. luteus DE2008 could be seen as a microorganism capable of restoring environments polluted by lead and copper.

Abstract
Porcine reproductive and respiratory syndrome virus (PRRSV) is endemic in most parts of Asia, where genotype I and II strains of diverse virulence may coexist. This study evaluated the outcome of infection with a highly virulent Asian genotype II PRRSV isolate in piglets vaccinated with a genotype I vaccine. Twenty-one 3-week-old piglets were divided in three groups: Pigs in group V (n=8) were vaccinated with an attenuated genotype I commercial PRRSV vaccine, while pigs in group U (n=8) and a control group (group C; n=5) were unvaccinated; 6 weeks later, pigs in groups V and U were challenged intranasally with a highly virulent strain of genotype II PRRSV (1×10(5) 50% tissue culture infectious doses/mL), while pigs in group C received a placebo. Over a period of 21 days after challenge, vaccinated pigs had significantly lower mortality (0/8 versus 2/8), fewer days of fever, a lower frequency of catarrhal bronchopneumonia, higher weight gains (13.4 versus 6.6 kg) and lower levels of viraemia compared to unvaccinated challenged pigs. Immunisation with a genotype I attenuated PRRSV vaccine provided partial protection against challenge with a highly virulent genotype II strain.

Abstract
Lead (Pb) is a metal that is non-essential to any metabolic process and, moreover, highly deleterious to life. In microbial mats - benthic stratified ecosystems - located in coastal areas, phototrophic microorganisms (algae and oxygenic phototrophic bacteria) are the primary producers and they are exposed to pollution by metals. In this paper we describe the search for bioindicators among phototrophic populations of Ebro delta microbial mats, using high-resolution microscopic techniques that we have optimized in previous studies. Confocal laser scanning microscopy coupled to a spectrofluorometric detector (CLSM-λscan) to determine in vivo sensitivity of different cyanobacteria to lead, and scanning electron microscopy (SEM) and transmission electron microscopy (TEM), both coupled to energy dispersive X-ray microanalysis (EDX), to determine the extra- and intracellular sequestration of this metal in cells, were the techniques used for this purpose. Oscillatoria sp. PCC 7515, Chroococcus sp. PCC 9106 and Spirulina sp. PCC 6313 tested in this paper could be considered bioindicators for lead pollution, because all of these microorganisms are indigenous, have high tolerance to high concentrations of lead and are able to accumulate this metal externally in extracellular polymeric substances (EPS) and intracellularly in polyphosphate (PP) inclusions. Experiments made with microcosms demonstrated that Phormidium-like and Lyngbya-like organisms selected themselves at the highest concentrations of lead assayed. In the present study it is shown that all cyanobacteria studied (both in culture and in microcosms) present PP inclusions in their cytoplasm and that these increase in number in lead polluted cultures and microcosms. We believe that the application of these microscopic techniques open up broad prospects for future studies of metal ecotoxicity.

Abstract
This study presents the results of the virological surveillance for swine influenza viruses (SIVs) in Belgium, UK, Italy, France and Spain from 2006 to 2008. Our major aims were to clarify the occurrence of the three SIV subtypes - H1N1, H3N2 and H1N2 - at regional levels, to identify novel reassortant viruses and to antigenically compare SIVs with human H1N1 and H3N2 influenza viruses. Lung tissue and/or nasal swabs from outbreaks of acute respiratory disease in pigs were investigated by virus isolation. The hemagglutinin (HA) and neuraminidase (NA) subtypes were determined using standard methods. Of the total 169 viruses, 81 were classified as 'avian-like' H1N1, 36 as human-like H3N2 and 47 as human-like H1N2. Only five novel reassortant viruses were identified: two H1N1 viruses had a human-like HA and three H1N2 viruses an avian-like HA. All three SIV subtypes were detected in Belgium, Italy and Spain, while only H1N1 and H1N2 viruses were found in UK and Northwestern France. Cross-hemagglutination inhibition (HI) tests with hyperimmune sera against selected older and recent human influenza viruses showed a strong antigenic relationship between human H1N1 and H3N2 viruses from the 1980s and H1N2 and H3N2 human-like SIVs, confirming their common origin. However, antisera against human viruses isolated during the last decade did not react with currently circulating H1 or H3 SIVs, suggesting that especially young people may be, to some degree, susceptible to SIV infections.

Abstract
Algae are primary producers in a wide variety of natural ecosystems, and these microorganisms have been used in bioremediation studies. Nevertheless, very little is known about the in vivo effect of heavy metals on individual living cells. In this paper, we have applied a method based on confocal laser scanning microscopy and lambda scan function (CLSM-λscan) to determine the effect of lead (Pb), at different concentrations, on the DE2009 microalga. At the same time, we have optimized a method based on CLSM and image-analysis software (CLSM-IA) to determine in vivo biomass of this microorganism. The results obtained by lambda scan function indicated that the pigment peak decreases while the concentration of metal increases at pH 7. On the other hand at pH 4 there is no good correlation between the concentration of metal and the intensity of the emission of fluorescence of the pigment. Also, in some cases a displacement of the Chl a peak towards 680 nm is produced. Total and individual biomass determined by CLSM-IA shows statistically significant differences between unpolluted and 10 mM polluted cultures. Complementary studies using electron microscopy techniques coupled to energy dispersive X-ray microanalysis (EDX) demonstrate that the microalga can sequestrate Pb extra- and intracellularly.

Abstract
The aim of the SINERGE study was to assess the impact of nocturnal heartburn on quality of life, sleep, and productivity. Ambulatory patients >/=18 years old and classified as defined cases of nocturnal heartburn (n=337), nonnocturnal heartburn (n=139), uncontrolled hypertension (n=198), and symptomatic depression (n=104) were included in this cross-sectional study. Information on age, gender, body mass index, and comorbidity was collected and the following validated questionnaires were applied: SF-12, Pittsburgh Sleep Quality Index, and Work Productivity and Activity Impairment questionnaire. The prevalence of primary care consultation for heartburn and nocturnal heartburn was 4.7% and 1.9%, respectively. Health-related quality of life, sleep, and productivity were significantly impaired in patients with frequent nocturnal heartburn symptoms as compared with those of the patients without nocturnal symptoms or patients with hypertension. Nocturnal heartburn poses a considerable burden for the sufferer because of the impact on quality of life, sleep, and daily activities.

Abstract
In coeliac disease (CD) there is an inflammatory status of the intestinal mucosa because of a high expression of proinflammatory mediators. The nuclear protein poly (ADP-ribose) polymerase-1 (PARP-1) has been implicated in the initial inflammatory response by modulating transcription of inflammation-related genes. The aim of this work was to investigate the role of PARP-1 gene promoter region haplotypes in relation to coeliac disease susceptibility. We analysed a coeliac population consisting of a case-control panel with 120 CD patients and 311 healthy blood donors. A CA microsatellite, as haplotype-defining variant of the whole PARP-1 promoter, was typed using a polymerase chain reaction (PCR) method combined with fluorescence technology. We considered two promoter haplotypes: A defined by short CA alleles (83-87 bp) and B defined by long CA alleles (89-101 bp). Haplotype A was significantly increased within the coeliac patients group (P = 0.007 OR 1.6 95%CI 1.12-2.35). Additionally, we observed a significant dose effect, showing homozygous individuals for haplotype A higher risk for CD susceptibility (P = 0.007, OR 1.79 95%CI 1.14-2.82). Our results provide the first evidence that PARP-1 haplotypes are related with coeliac disease susceptibility.
