Within the last two decades, several high-impact viruses have emerged in the global swine population, including porcine reproductive and respiratory syndrome virus (PRRSV). In Uruguay, the more recent serological survey for PRRSV and other notifiable diseases such as Aujeszky's disease virus (ADV) and classical swine fever virus (CSFV) dated from year 2000. The main purpose of this study was to update our information on the infection status of PRRSV, ADV and CSFV in Uruguayan pig herds, in order to keep informed about the epidemiological situation of these notifiable infections in the country...

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease in humans caused by the CCHF virus (CCHFV). The detection of anti-CCHFV antibodies in animals is used to reveal infection risk areas. Therefore a simple, quick and reliable multispecies assay for the detection of CCHFV-specific antibodies is needed. This work presents the development and validation of a novel CCHF double-antigen ELISA for the detection of anti-CCHFV nucleoprotein antibodies. The test requires 30 μl of serum, and results are obtained within 90 min...

Protein p72 is the major capsid protein of African swine fever virus (ASFV) and is an important target for test and vaccine development. Monoclonal antibodies (mAbs) were prepared against a recombinant antigenic fragment, from amino acid (aa) 20-303, expressed in baculovirus. A total of 29 mAbs were recovered and tested by immunofluorescent antibody (IFA) staining on ASFV Lisbon-infected Vero cells. Six antibodies were IFA-positive and selected for further characterization. Epitope mapping was performed against overlapping polypeptides expressed in E...

Lithium chloride (LiCl) has been reported to possess antiviral activity against several viruses. In the current study, we assessed the antiviral activity effect of LiCl on ALV-J infection in CEF cells by using real-time PCR, Western blot analysis, IFA and p27 ELISA analysis. Our results showed that both viral RNA copy number and protein level decreased significantly in a dose and time dependent manner. Time-course analysis revealed that the antiviral effect was more pronounced when CEFs were treated at the post infection stage rather than at early absorption or pre-absorption stages...

Plasmodium lactate dehydrogenase (pLDH) is a strong target antigen for the determination of infection with Plasmodium species specifically. However, a more effective antibody is needed because of the low sensitivity of the current antibody in many immunological diagnostic assays. In this study, recombinant Plasmodium vivax LDH (PvLDH) was experimentally constructed and expressed as a native antigen to develop an effective P. vivax-specific monoclonal antibody (mAb). Two mAbs (2CF5 and 1G10) were tested using ELISA and immunofluorescence assays (IFA), as both demonstrated reactivity against pLDH antigen...

Ifosfamide (IFA) is a potent alkylating antitumoral agent but its use is limited by neurological side effects. IFA is a racemic mixture of two enantiomeric forms, R-IFA and S-IFA with a stereoselective metabolism by CYP3A4 and CYP2B6, leading either to bioactive or to toxic pathways. In 3 consecutive cases of pediatric patients who exhibited ifosfamide-induced encephalopathy (IIE), genotyping of clinically relevant single nucleotide polymorphisms associated with decreased CYP3A4 and CYP2B6 activities was performed...

Violence involving firearms poses a serious threat to public safety in urban areas. The present study examines how illegal firearm availability (IFA) is related to firearm violence at the neighborhood level. We analyzed 3 years (from 2005 to 2007) of recovered firearm and violent index crime data from Newark, New Jersey. Violent index crime is separated into three categories by level of firearm use: shootings, display of firearm violence (DFV), and no-firearm violence (NFV). Negative binominal regression was conducted to examine the relationship between IFA and firearm violence at the neighborhood level while controlling for neighborhood conditions...

This study presented a strategy for recovering partial nitritation-anammox (PN/A) of real sewage from nitrate accumulation using free nitrous acid (FNA) treatment. Sewage PN/A was successfully achieved in an integrated fixed-film activated sludge (IFAS) reactor but effluent nitrate gradually increased. For recovering the system performance, flocculent sludge of the reactor was collected and treated with FNA of 1.35 mg/L for 24 h. After FNA treatment, effluent nitrate decreased from 17.6 to 6.1 mg/L with an increase of total nitrogen removal efficiency from 29...

Porcine reproductive and respiratory syndrome virus (PRRSV) nucleocapsid protein (NP) is the immunodominant region of PRRSV viral proteins. Non-structural protein 2 (Nsp2) and its hypervariable region play an essential role in the differential diagnosis of PRRSV. Western blot and immunofluorescence assay (IFA) analyses found that 2 out of 18 monoclonal antibodies (MAbs) recognized the NP and that 5 of 11 MAbs recognized Nsp2-120aa. IFA data demonstrated that 2 MAbs raised against the NP have a positive reaction to PRRSV; either HP-PRRSV, classic PRRSV or the vaccine strain at 1:100 dilution...

Non-human primates currently serve as the best experimental model for Lyme disease due to their close genetic homology with humans and demonstration of all three phases of disease following infection with Borreliella (Borrelia) burgdorferi (Bb). We investigated the pathology associated with late disseminated Lyme disease (12 to 13 months following tick inoculation) in doxycycline-treated (28 days; 5mg/kg, oral, 2x/day) and untreated rhesus macaques (Rm). Minimal to moderate lymphoplasmacytic inflammation, with a predilection for perivascular spaces and collagenous tissues, was observed in multiple tissues including the cerebral leptomeninges, brainstem, peripheral nerves from both fore and hind limbs, stifle synovium and perisynovial adipose tissue, urinary bladder, skeletal muscle, myocardium, and visceral pericardium...

There is considerable global evidence on the effectiveness of cash transfers in improving health and nutrition outcomes; however, the evidence from South Asia, particularly India, is limited. In the context of India where more than a third of children are undernourished, and where there is considerable under-utilization of health and nutrition interventions, it is opportune to investigate the impact of cash transfer programs on the use of interventions. We study one conditional cash transfer program, Mamata scheme, implemented in the state of Odisha, in India that targeted pregnant and lactating women...

Nearly two thirds of young children are anaemic in Bihar, India. Paediatric iron and folic acid syrup (IFAS) and multiple micronutrient powders (MNPs) are two evidence-based interventions to prevent anaemia. Using a randomized crossover design, we examined the acceptability of IFAS versus MNPs for children 6-23 months. In a catchment area of 2 health centres in Bihar, health front-line workers (FLWs) delivered either (a) IFAS twice weekly or (b) MNPs for 1 month followed by the other supplementation strategy for 1 month to the same families (NCT02610881)...

BACKGROUND: Early childhood is a critical phase of development. In low resource settings, monitoring this stage of development and providing appropriate and timely feedback is a challenge. Community-based service providers play a key role in promoting early childhood development in areas where government services are weak. These community-based service providers are also tasked with the collection of monitoring and evaluation data for donors and local government. Usually, collection of these data aims to provide accountability, learning, and correction leading to improvement...
