Effects of heat stress abatement on systemic and mammary inflammation in lactating dairy cows.

To examine the effects of evaporative cooling on systemic and mammary inflammation of lactating dairy cows, 30 multiparous Holstein cows (parity = 2.4, 156 d in milk) were randomly assigned to 1 of 2 treatments: cooling (CL) with fans and misters or not (NC). The experiment was divided into a 10-d baseline when all cows were cooled, followed by a 36-d environmental challenge when cooling was terminated for NC cows. The onset of environmental challenge was considered as d 1. Temperature-humidity index averaged 78.4 during the environmental challenge. Milk yield and dry matter intake (DMI) were recorded daily. Blood and milk samples were collected from a subset of cows (n = 9/treatment) on d -3, 1, 3, 7, 14, and 28 of the experiment to measure cortisol, interleukin 10 (IL10), tumor necrosis factor-α (TNF-α), haptoglobin, and lipopolysaccharide binding protein (LBP). Mammary biopsies were collected from a second subset of cows (n = 6/treatment) on d -9, 2, 10, and 36 to analyze gene expression of cytokines and haptoglobin. A subset of cows (n = 7/treatment) who were not subjected to mammary biopsy collection received a bolus of lipopolysaccharides (LPS) in the left rear quarter on d 30 of the experiment. Blood was sampled from cows and milk samples from the LPS-infused quarter were collected at -4, 0, 3, 6, 12, 24, 48, and 96 h relative to infusion, for analyses of inflammatory products. Deprivation of cooling decreased milk yield and DMI. Compared with CL cows, plasma cortisol concentration of NC cows was higher on d 1 but lower on d 28 of the experiment (cooling × time). Deprivation of cooling did not affect circulating TNF-α, IL10, haptoglobin, or LBP. Compared with CL cows, NC cows tended to have higher milk IL10 concentrations but did not show effects in TNF-α, haptoglobin, or LBP. No differences were observed in mammary tissue gene expression of TNF-α, IL10, and haptoglobin. Milk yield declined after LPS infusion but was not affected by treatment. Compared with CL cows, NC cows had greater milk somatic cell count following intramammary LPS infusion. Non-cooled cows had lower circulating TNF-α and IL10 concentrations and tended to have lower circulating haptoglobin concentrations than CL cows. Milk IL10 and TNF-⍺ concentrations were higher 3 h after LPS infusion for NC cows compared with CL cows. Additionally, NC cows tended to have higher milk haptoglobin concentration after LPS infusion than CL cows. In conclusion, deprivation of evaporative cooling had minimal effects on lactating cows' basal inflammatory status, but upregulated mammary inflammatory responses after intramammary LPS infusion.

Introduction: Sleep disorders and chronic pain are linked to each other bidirectionally. Both are related to affective disorders, fatigue, depression, anxiety and drug abuse, and have a significant effect on quality of life. The Interdisciplinary Pain Programme (IDP) aims to relieve the patients’ pain and improve their functionality by incorporating healthy postural, sleep and nutritional habits, relaxation techniques, physical exercise and cognitive-behavioural mechanisms. Patients and methods: A retrospective, observational, cross-sectional study was conducted. A total of 323 patients with chronic pain who completed the IDP were examined. They were assessed at the beginning and at the end of the programme with pain, depression, quality of life and insomnia scales, and were then compared between groups with and without insomnia, that is, with an insomnia severity index (ISI) less than 15 versus greater than or equal to 15. Fifty-eight patients were studied by means of polysomnography. Results: A significant improvement (p < 0.0001) in pain, depression and quality of life, as assessed by the visual analogue scale (VAS), the Beck inventory and the Short Form-36 (SF-36) questionnaire was observed in chronic pain patients with an ISI below 15 and in those with an ISI greater than or equal to 15. The results were superior in the group of patients with insomnia. The presence of a high apnoea and hypopnoea index and periodic lower limb movements in patients was not related to improvements on the Beck, SF-36, ISI and VAS scales. Conclusions: In conclusion, IDP benefits patients with chronic non-cancer-induced pain in several affected areas, in addition to pain, due to a comprehensive treatment. Polysomnography can help diagnose specific pathologies and individualise pharmacological treatment.(AU)

Prevalencia de alteraciones digestivas asociadas a Chagas importado (estudio PADChI): un estudio observacional / Prevalence of digestive disorders associated with imported Chagas disease (PADChI study): an observational study

Background Chagas disease (CD) is a parasitic disease caused by Trypanosoma cruzi, in which up to 10–20% of those affected may suffer digestive disorders. Multiple studies have been carried out on CD in non-endemic countries, mainly related to cardiological involvement. However, digestive disorders have not been analyzed in such depth. The objective of the study was to determine the prevalence of digestive disorders in imported CD at the time of first care. Methods An observational cross-sectional descriptive analysis of imported CD was performed. Chagasic structural damage and infectious digestive comorbidity were evaluated. The association between Chagasic structural damage and heart disease in Chagas patients was also investigated. Results After reviewing a total of 1,216 medical records, those of 464 patients were selected for analysis. Globally, the prevalence of digestive disorders in imported Chagas was 57.76%, 95% CI (53.25–62.27). The prevalence of comorbidity of infectious diseases was 40.73% CI 95% (36.25–45.22). Colonic abnormalities were found in 84 of 378 barium enema patients. CD-related esophageal abnormalities were present in 63 of 380 patients studied with esophagogram. Conclusions The prevalence of digestive disorders associated with CD is high, so the presence of infectious diseases (mainly parasitic and H. pylori infection) should be ruled out. It is important to exclude structural involvement in all symptomatic patients, and asymptomatic patients should also be considered and offered (AU)

Antecedentes La enfermedad de Chagas (EC) es una enfermedad parasitaria causada por Trypanosoma cruzi, en la que hasta un 10–20% de los afectados pueden sufrir trastornos digestivos. Se han realizado múltiples estudios sobre la EC en países no endémicos, principalmente relacionados con el compromiso cardiológico. Sin embargo, los trastornos digestivos no se han analizado con tanta profundidad. El objetivo del estudio fue determinar la prevalencia de los trastornos digestivos en la EC importada en el momento de la primera atención. Métodos Se realizó un análisis descriptivo transversal observacional de la EC importada. Se evaluó el daño estructural chagásico y la comorbilidad digestiva infecciosa. También se investigó la asociación entre el daño estructural chagásico y la enfermedad cardíaca en pacientes con Chagas. Resultado Tras la revisión de un total de 1.216 historias clínicas, se seleccionaron para el análisis las de 464 pacientes. A nivel global, la prevalencia de trastornos digestivos en Chagas importado fue del 57,76% IC95% (53,25–62,27). La prevalencia de comorbilidad de enfermedades infecciosas fue de 40,73% IC95% (36,25–45,22). Se encontraron anomalías colónicas en 84 de 378 pacientes con enema de bario. Las anomalías esofágicas relacionadas con la EC estuvieron presentes en 63 de 380 pacientes estudiados con esofagograma. Conclusiones La prevalencia de trastornos digestivos asociados a EC es alta, por lo que conviene descartar la presencia de enfermedades infecciosas (principalmente parasitarias e infección por H. pylori). Es importante excluir afectación estructural en todos los pacientes sintomáticos, y también se debería considerar y ofrecer a pacientes asintomáticos (AU)

It is important to exclude structural involvement in all symptomatic patients, and asymptomatic patients should also be considered and offered.

H2A.Z overexpression suppresses senescence and chemosensitivity in pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most intractable and devastating malignant tumors. Epigenetic modifications such as DNA methylation and histone modification regulate tumor initiation and progression. However, the contribution of histone variants in PDAC is unknown. Here, we demonstrated that the histone variant H2A.Z is highly expressed in PDAC cell lines and PDAC patients and that its overexpression correlates with poor prognosis. Moreover, all three H2A.Z isoforms (H2A.Z.1, H2A.Z.2.1, and H2A.Z.2.2) are highly expressed in PDAC cell lines and PDAC patients. Knockdown of these H2A.Z isoforms in PDAC cell lines induces a senescent phenotype, cell cycle arrest in phase G2/M, increased expression of cyclin-dependent kinase inhibitor CDKN2A/p16, SA-ß-galactosidase activity and interleukin 8 production. Transcriptome analysis of H2A.Z-depleted PDAC cells showed altered gene expression in fatty acid biosynthesis pathways and those that regulate cell cycle and DNA damage repair. Importantly, depletion of H2A.Z isoforms reduces the tumor size in a mouse xenograft model in vivo and sensitizes PDAC cells to gemcitabine. Overexpression of H2A.Z.1 and H2A.Z.2.1 more than H2A.Z.2.2 partially restores the oncogenic phenotype. Therefore, our data suggest that overexpression of H2A.Z isoforms enables cells to overcome the oncoprotective barrier associated with senescence, favoring PDAC tumor grow and chemoresistance. These results make H2A.Z a potential candidate as a diagnostic biomarker and therapeutic target for PDAC.

Effects of evaporative cooling and dietary zinc source on heat shock responses and mammary gland development in lactating dairy cows during summer.

The objective of this study was to examine the effects of evaporative cooling and dietary supplemental Zn source on heat shock responses and mammary gland development of lactating dairy cows during summer. Seventy-two multiparous lactating Holstein cows were randomly assigned to 1 of 4 treatments in a 2 × 2 factorial arrangement. Cows were either cooled (CL) or not cooled (NC) and fed diets supplemented with 75 mg of Zn/kg of dry matter (DM) from Zn hydroxychloride (IOZ) or 35 mg of Zn/kg of DM from Zn hydroxychloride plus 40 mg of Zn/kg of DM from Zn-Met complex (ZMC). The 168-d trial included a 12-wk baseline phase when all cows were cooled and fed respective dietary treatments, and a subsequent 12-wk environmental challenge phase when NC cows were deprived of evaporative cooling. Plasma was collected from a subset of cows (n = 24) at 1, 3, 5, 12, 26, 41, 54, 68, 81 d of the environmental challenge to measure heat shock protein (HSP) 70 concentration. Mammary biopsies were collected from another subset of cows (n = 30) at enrollment (baseline samples) and at d 7 and 56 of the environmental challenge to analyze gene expression related to heat shock response, apoptosis and anti-oxidative enzymes, and to examine apoptosis and cell proliferation using immunohistochemistry. Supplemental Zn source did not affect milk yield but NC cows produced less milk than CL cows. Supplemental Zn source had no effect on mammary gene expression of HSP27, 70, and 90 or plasma concentrations of HSP70. The NC cows had greater mammary gene expression of HSP than CL cows. Circulating HSP70 of NC cows gradually increased and was higher at 81 d of environmental challenge compared with CL cows. Relative to IOZ, ZMC cows tended to have lower total mammary cell proliferation but greater mammary apoptosis. There was a tendency of greater TNFRSF1A mRNA expression for ZMC compared with IOZ cows, which may suggest upregulated extrinsic apoptosis. At d 7 of environmental challenge, NC cows had numerically higher mammary apoptosis than CL cows although not statistically significant. The NC cows tended to have greater mRNA expression of CAT and SOD3 regardless of time, and had greater mRNA expression of GPX1 at d 56 and FAS at d 7 of the environmental challenge than CL cows. Relative to CL cows, mammary cell proliferation rate was higher for NC cows at d 56 of the environmental challenge. In conclusion, dietary source of supplemental Zn has substantial effect on mammary cell turnover in lactating dairy cows, and prolonged exposure to heat stress increases mammary cell proliferation.

Spatial variability of the green water footprint using a medium-resolution remote sensing technique: The case of soybean production in the Southeast Argentine Pampas.

Agriculture accounts for about 70% of the fresh water use in the world, dominating rainfed production systems. As meeting future food demand will require an increase in crop production, new techniques are necessary to monitor the spatial variability of agricultural water use. However, the use of remote sensing for the water footprint estimation is limited. This study aims at evaluating the spatial variability of the soil-water consumption in soybean crops, also termed as green water footprint (WFgreen), in a sector of the Argentine Pampas using satellite data. WFgreen was evaluated at spatial resolution of 250 m, estimating the soil water availability through the evaporative fraction and crop yield from Moderate-Resolution Imaging Spectroradiometer (MODIS/Aqua) data. In the analysed soybean plots, the WFgreen varied from 900 m3 t-1 to 1800 m3 t-1. The preliminary comparison of the method with field measurements showed a RMSE = 494 m3 t-1 and Bias = -410 m3 t-1, respectively. The high spatial variability reflected the heterogeneity of soil-water use efficiency. The proposed technique can be useful to obtain WFgreen maps at medium spatial resolutions (250 m-1000 m). Also, it can be applied in regions with poor ground data coverage to estimate the WFgreen, after a parameterization of the model. The contribution to our understanding of the relationship between soil-water availability, rainfed-crop productivity and then WFgreen is expected.

Prevalence of Spasticity and Postural Patterns in the Upper Extremity Post Stroke.

INTRODUCTION: A high number of patients with stroke develop upper extremity spasticity, causing abnormal postures and patterns. These alterations limit the use of arm in functional activities and affect social participation. AIM: To determine the prevalence of spasticity and postural patterns of the upper extremity post stroke. MATERIALS AND METHODS: A cross-sectional descriptive design was used with a prospective follow-up. The sample included 136 patients. The study included 3 measuring times; at 10 days (T1), applying a record with sociodemographic-clinical data, the evaluation of muscle tone in the elbow and wrist and the postural patterns of the UE, and at 3 months (T2) and 12 months (T3) post stroke, re-evaluating tone and patterns. Prevalence was calculated through the one-sample chi-squared (χ2) test followed by inspection of the standardized residuals (z) in each cell. The Kappa coefficient evaluated the degree of agreement in elbow and wrist tone. RESULTS: The prevalence of spasticity in the elbow was 37.5% at T1, 57.4% at T2, and 57.4% at T3. At each time there was a high degree of agreement between elbow and wrist tone. Patients developed increased elbow tone between T1 and T2, with maintained tone between T2 and T3. Postural pattern III was the most prevalent according to Hefter's classification. CONCLUSION: The prevalence of spasticity in the elbow and wrist increases between 10 days and 3 months post stroke, and is maintained between 3 and 12 months. The onset of spasticity occurs in almost half of patients during the first 10 days post stroke. Postural pattern III according to Hefter's classification presented the greatest prevalence in the spastic UE.

Effects of milk replacer feeding levels on performance and metabolism of preweaned dairy calves during summer.

The objective of this study was to evaluate the effect of milk replacer (MR) feeding programs on performance and metabolism during summer. At 3 d of age (DOA), calves were randomly assigned to 1 of 4 dietary treatments: control [CON; 0.55 kg dry matter (DM) of a 20% crude protein (CP) and 20% fat MR per day], intermediate (IL; 0.66 kg DM of a 26% CP and 17% fat MR per day), high (HL; 0.77 kg DM of a 26% CP and 17% fat MR per day), or aggressive (AL; 0.87 kg DM of a 26% CP and 17% fat MR per day). Calves were managed similarly and housed in individual polyethylene hutches using sand as a bedding material. Because 3 calves fed the AL diet developed abomasum bloating during the first 30 DOA, the AL treatment was terminated. Milk replacer (12.5% solids) was offered twice daily until 42 DOA, when MR was fed once daily to reduce its intake by 50%. Calves were weaned at 49 DOA and remained in hutches until 56 DOA. Calf starter and water were offered ad libitum. Ambient temperature and relative humidity in and outside the hutches were assessed hourly. Starter and MR intakes were recorded daily. Respiration rate and rectal temperature were determined 3 times each week. Body weight was measured at 3, 14, 28, 42, and 56 DOA. Plasma was collected at 5, 10, 14, 28, 42, 43, 45, 47, 49, 51, and 56 DOA for analysis of glucose, ß-hydroxybutyrate, triglycerides, nonesterified fatty acids, urea nitrogen, and insulin concentrations. There were no treatment effects on starter intake, rectal temperature, or respiration rate. By 7 DOA, calves fed the IL and HL diets consumed the same amount of MR and a higher amount of MR than the CON calves. At wk 2, calves from all treatments had similar MR consumption before returning to the projected intake by design at wk 4. Calves fed the IL and HL treatments had similar body weight but were heavier than those fed the CON diet at wk 6, 7, and 8. Calves fed the IL and HL diets had similar average daily gain, which was higher than that of calves fed the CON diet. There was no difference in plasma metabolites among treatments, but insulin concentration increased as milk allowance increased. In summary, feeding an intermediate level of MR during summer improved calf growth compared with the CON diet, but a higher MR allowance did not support further improvements in calf performance.

Efectos de la espasticidad en la recuperación motora posterior a un ACV / Effects of spasticity on motor recovery after a stroke

Impact of Physiological Signals Acquisition in the Emotional Support Provided in Learning Scenarios.

Physiological sensors can be used to detect changes in the emotional state of users with affective computing. This has lately been applied in the educational domain, aimed to better support learners during the learning process. For this purpose, we have developed the AICARP (Ambient Intelligence Context-aware Affective Recommender Platform) infrastructure, which detects changes in the emotional state of the user and provides personalized multisensorial support to help manage the emotional state by taking advantage of ambient intelligence features. We have developed a third version of this infrastructure, AICARP.V3, which addresses several problems detected in the data acquisition stage of the second version, (i.e., intrusion of the pulse sensor, poor resolution and low signal to noise ratio in the galvanic skin response sensor and slow response time of the temperature sensor) and extends the capabilities to integrate new actuators. This improved incorporates a new acquisition platform (shield) called PhyAS (Physiological Acquisition Shield), which reduces the number of control units to only one, and supports both gathering physiological signals with better precision and delivering multisensory feedback with more flexibility, by means of new actuators that can be added/discarded on top of just that single shield. The improvements in the quality of the acquired signals allow better recognition of the emotional states. Thereof, AICARP.V3 gives a more accurate personalized emotional support to the user, based on a rule-based approach that triggers multisensorial feedback, if necessary. This represents progress in solving an open problem: develop systems that perform as effectively as a human expert in a complex task such as the recognition of emotional states.

Legumes display common and host-specific responses to the rhizobial cellulase CelC2 during primary symbiotic infection.

Primary infection of legumes by rhizobia involves the controlled localized enzymatic breakdown of cell walls at root hair tips. Previous studies determined the role of rhizobial CelC2 cellulase in different steps of the symbiotic interaction Rhizobium leguminosarum-Trifolium repens. Recent findings also showed that CelC2 influences early signalling events in the Ensifer meliloti-Medicago truncatula interaction. Here, we have monitored the root hair phenotypes of two legume plants, T. repens and M. sativa, upon inoculation with strains of their cognate and non-cognate rhizobial species, R. leguminosarum bv trifolii and E. meliloti, (over)expressing the CelC2 coding gene, celC. Regardless of the host, CelC2 specifically elicited 'hole-on-the-tip' events (Hot phenotype) in the root hair apex, consistent with the role of this endoglucanase in eroding the noncrystalline cellulose found in polarly growing cell walls. Overproduction of CelC2 also increased root hair tip redirections (RaT phenotype) events in both cognate and non-cognate hosts. Interestingly, heterologous celC expression also induced non-canonical alterations in ROS (Reactive Oxygen Species) homeostasis at root hair tips of Trifolium and Medicago. These results suggest the concurrence of shared unspecific and host-related plant responses to CelC2 during early steps of symbiotic rhizobial infection. Our data thus identify CelC2 cellulase as an important determinant of events underlying early infection of the legume host by rhizobia.

Carcinoma epidermoide y quiste hidatídico pulmonar. Una asociacion infrecuente / Squamous cell lung carcinoma and lung hydatid cyst. An uncommon association

La coexistencia de una neoplasia pulmonar, en general carcinoma broncogénico, y un quiste hidatídico simultáneo es una entidad poco frecuente, aunque descrita en la literatura. En nuestro artículo describimos un caso clínico de un paciente con un carcinoma epidermoide y un quiste hidatídico pulmonar en el mismo lóbulo sometido a resección quirúrgica, en un paciente con hidatidosis hepática conocida, junto con una revisión de la literatura. Los hallazgos radiológicos son sugestivos pero sólo los hallazgos histológicos de la cirugía permiten el diagnóstico de confirmación

The coexistence of lung cancer and lung hydatid cyst is exceptional, however there were few cases describe in literature. We describe a clinical case with both entities in the same lobe treated with lung resection and a review of the literature. The radiological suspicion of both entities is essential but only surgery histological findings allows this partnership confirmation

[Rate of readmissions of patients with heart failure: effects of multifactorial educational interventions]. / Efectividad de las intervenciones educativas con enfoque multifactorial y seguimiento vía telefónica sobre la rehospitalización en pacientes con insuficiencia cardiaca: revisión sistemática y meta-análisis.

We performed a systematic review of the literature to analyze the effect on readmission rates of multifactorial educational interventions at the moment of discharge from the hospital and telephone follow up for patients with heart failure. The quality of reports was analyzed using the CONSORT verification list and the GRADE guide. Using Rev Manager 5.3, the relative risk heterogeneity (RR) of readmission was assessed using I2 and Q statistics, and those considered as homogeneous were combined into a single RR as the confidence interval. We included four reports in the review and three were meta-analyzed. The RR for readmission was 1.01 (95% confidence interval (CI): 0.73-1.40; p = 0.96) with educational interventions and telephone follow-up among patients who visited an emergency room (ER). When studies that included readmission (without ER visit) were combined, the RR was 0.83 (95% CI:0.58-1.17). When studies with visits to ER and readmissions were combined, the RR was 0.91 (95% CI:0.73-1.14). We conclude that educational interventions did not have a significant effect on the rate of readmissions of patients with heart failure.

Experimental study of the susceptibility of a European Aedes albopictus strain to dengue virus under a simulated Mediterranean temperature regime.

Dengue virus (DENV) has re-emerged in Europe driven by the geographic expansion of the mosquito species Aedes albopictus and Aedes aegypti (Diptera: Culicidae) and the introduction of the virus by viraemic travellers. In the present study, the vector competence (VC) of Ae. albopictus collected in Catalonia (northeast Spain) was evaluated for two different DENV strains, DENV-1 and DENV-2, the serotypes responsible for all outbreaks of dengue that have occurred in Europe. Mosquitoes were reared under environmental conditions mimicking the mean temperature and humidity recorded in July on the Mediterranean coast of Catalonia. Mosquitoes were fed on an artificial infectious bloodmeal and, at 14 days post-exposure, infection, disseminated infection and transmission rates (IR, DIR, TR) and transmission efficiency (TE) were determined by testing the virus in the body, legs and saliva. The tested Ae. albopictus strain was found to be susceptible to both DENV-1 and DENV-2 and to be able to transmit DENV-1. This is the first time that the VC of Ae. albopictus for DENV has been tested in Europe in this specific context (i.e. mimicking the Mediterranean temperature and humidity recorded in Catalonia in July). This study confirms the potential of Ae. albopictus to start autochthonous DENV transmission cycles in the Mediterranean basin.

Efectividad de las intervenciones educativas con enfoque multifactorial y seguimiento vía telefónica sobre la rehospitalización en pacientes con insuficiencia cardiaca: revisión sistemática y meta-análisis / Rate of readmissions of patients with heart failure: effects of multifactorial educational interventions

We performed a systematic review of the literature to analyze the effect on readmission rates of multifactorial educational interventions at the moment of discharge from the hospital and telephone follow up for patients with heart failure. The quality of reports was analyzed using the CONSORT verification list and the GRADE guide. Using Rev Manager 5.3, the relative risk heterogeneity (RR) of readmission was assessed using I2 and Q statistics, and those considered as homogeneous were combined into a single RR as the confidence interval. We included four reports in the review and three were meta-analyzed. The RR for readmission was 1.01 (95% confidence interval (CI): 0.73-1.40; p = 0.96) with educational interventions and telephone follow-up among patients who visited an emergency room (ER). When studies that included readmission (without ER visit) were combined, the RR was 0.83 (95% CI:0.58-1.17). When studies with visits to ER and readmissions were combined, the RR was 0.91 (95% CI:0.73-1.14). We conclude that educational interventions did not have a significant effect on the rate of readmissions of patients with heart failure.

Transmission and immunopathology of the avian influenza virus A/Anhui/1/2013 (H7N9) human isolate in three commonly commercialized avian species.

H7N9 virus infection is a global concern, given that it can cause severe infection and mortality in humans. However, the understanding of H7N9 epidemiology, animal reservoir species and zoonotic risk remains limited. This work evaluates the pathogenicity, transmissibility and local innate immune response of three avian species harbouring different respiratory distribution of α2,6 and α2,3 SA receptors. Muscovy ducks, European quails and SPF chickens were intranasally inoculated with 105 embryo infectious dose (EID)50 of the human H7N9 (A/Anhui/1/2013) influenza isolate. None of the avian species showed clinical signs or macroscopic lesions, and only mild microscopic lesions were observed in the upper respiratory tract of quail and chickens. Quail presented more severe histopathologic lesions and avian influenza virus (AIV) positivity by immunohistochemistry (IHC), which correlated with higher IL-6 responses. In contrast, Muscovy ducks were resistant to disease and presented higher IFNα and TLR7 response. In all species, viral shedding was higher in the respiratory than in the digestive tract. Higher viral shedding was observed in quail, followed by chicken and ducks, which presented similar viral titres. Efficient transmission was observed in all contact quail and half of the Muscovy ducks, while no transmission was observed between chicken. All avian species showed viral shedding in drinking water throughout infection.

Rift Valley fever virus and European mosquitoes: vector competence of Culex pipiens and Stegomyia albopicta (= Aedes albopictus).

Rift Valley fever (RVF) is a mosquito-borne disease caused by the Rift Valley fever virus (RVFV). Rift Valley fever affects a large number of species, including human, and has severe impact on public health and the economy, especially in African countries. The present study examined the vector competence of three different European mosquito species, Culex pipiens (Linnaeus, 1758) form molestus (Diptera: Culicidae), Culex pipiens hybrid form and Stegomyia albopicta (= Aedes albopictus) (Skuse, 1894) (Diptera: Culicidae). Mosquitoes were artificially fed with blood containing RVFV. Infection, disseminated infection and transmission efficiency were evaluated. This is the first study to assess the transmission efficiency of European mosquito species using a virulent RVFV strain. The virus disseminated in Cx. pipiens hybrid form and in S. albopicta. Moreover, infectious viral particles were isolated from saliva of both species, showing their RVFV transmission capacity. The presence of competent Cx. pipiens and S. albopicta in Spain indicates that an autochthonous outbreak of RVF may occur if the virus is introduced. These findings provide information that will help health authorities to set up efficient entomological surveillance and RVFV vector control programmes.
