Caracterización de cepas de campo de Herpesvirus suino 1 aisladas en Argentina

Caracterización de cepas de campo de Herpesvirus suino 1 aisladas en Argentina. Se caracterizaron cepas argentinas de herpesvirus suino tipo 1 (HVS-1) mediante corte con las enzimas de restricción BamHI, BstEII y XhoI. La presencia del tipo genómico II había sido reportada en la Argentina una sola vez y, hasta el momento, no se han informado nuevos casos. Este estudio reveló una homogeneidad de los sitios BamHI, acorde con el número y el tamaño de los fragmentos. La presencia del fragmento BamHI #7 en los aislamientos argentinos analizados sugiere que éstos pertenecen al tipo salvaje (wild-type). Además, se caracterizó el principal dominio inmunogénico de la glicoproteína E de todas las cepas argentinas y se lo comparó con los de las cepas de referencia y con las secuencias disponibles en la base de datos GenBank. Los porcentajes de similitud obtenidos oscilaron entre 99 y 100%.The genomic characterization of Suid herpesvirus 1 (SHV-1) isolates from Argentina was accomplished by restriction pattern analysis using the BamHI, BstEII and XhoI enzymes. Type II genome has been described only once in Argentina. This study revealed considerable homogeneity of BamHI endonuclease sites in all the strains analyzed, according to the number and size of the fragments. No deletion of BamHI fragment #7 among the Argentinean isolates suggests that these strains are wild-type. In addition, the main antigenic domain of glycoprotein E of all the Argentinean strains, as well as the reference strains and sequences available in the GenBank, were characterized. The similarity percent oscillated between 99 and 100%.Fil: Serena, Maria Soledad. Universidad Nacional de La Plata. Facultad de Ciencias Veterinarias. Departamento de Microbiología.

Equine arteritis virus gP5 protein induces apoptosis in cultured insect cells

Equine Arteritis Virus (EAV) has been shown to induce apoptosis in vitro but the induction of this mechanism has not been previously associated with any viral gene product. In this work, we found a cytotoxicity effect of the EAV gP5 protein on baculovirus-insect cells and a low yield of protein recovery. Besides, different morphological features by electron transmission microscopy, DNA fragmentation in agarose gel, TUNEL analysis and caspase 3 activity were found. All these findings indicate that the EAV gP5 protein induces apoptosis in insect cells.Fil: Metz, German Ernesto. Universidad Nacional de la Plata. Facultad de Ciencias Veterinarias.

Development of a peptide ELISA for the diagnosis of Equine arteritis virus

A peptide-based indirect ELISA was developed to detect antibodies against Equine arteritis virus (EAV). Two peptides for epitope C of protein GP5 and fragment E of protein M were designed, synthesized, purified and used as antigens either alone or combined. Ninety-two serum samples obtained from the 2010 Equine viral arteritis outbreak, analyzed previously by virus neutralization, were evaluated by the ELISA here developed. The best resolution was obtained using peptide GP5. The analysis of the inter- and intraplate variability showed that the assay was robust. The results allow concluding that this peptide-based ELISA is a good alternative to the OIE-prescribed virus neutralization test because it can be standardized between laboratories, can serve as rapid screening, can improve the speed of diagnosis of EAV-negative horses and can be particularly useful for routine surveillance in large populations.Fil: Metz, German Ernesto.

Detection and molecular characterization of porcine parvovirus in fetal tissues from sows without reproductive failure in Argentina

Porcine parvovirus (PPV) is one of many pathogens responsible for reproductive failure in pregnant sows. Several studies have reported the appearance of new PPV strains that differ from previous isolates both genetically and antigenically. Thus, the protective effects of commercially inactivated vaccines could not be complete. In South America, the information about PPV is limited. Thus, the aim of the present study was to detect and characterize the PPV strains present in 131 mummies or stillbirths from normal deliveries in sows from a commercial swine farm of Argentina that uses the commercial vaccine. PCR results showed that 17/131 were positive to PPV. Ten of these viruses were isolated and sequenced. All viruses were related to the PPV1 sequence (NADL-2), maintaining the amino acid differences in positions 436 (S–P) and 565 (R–K). This study is the first to report the isolation of PPV in Argentina and the results suggest that PPV can cross the placenta even in vaccinated sows, thus affecting some of the fetuses and being able to cause fetal death in sows without reproductive failure. The results also suggest that vaccination only reduces clinical signs and reproductive disorders and may thus not be a perfect tool to manage PPV infection. This study provides information that needs to be studied in depth to improve strategies to prevent and control PPV infection in swine farms.Fil: Serena, Maria Soledad.

The third great leap: animal coronaviruses in Latin America

Una partícula viral de aproximadamente 120 nm ha modificado totalmente lo que sucede en nuestro mundo de 12.000 km de diámetro. La primera epidemia del coronavirus del síndrome respiratorio agudo grave (SARS), y luego la del síndrome respiratorio de Oriente Medio (MERS), alertaron del potencial de transmisión entre especies de esta familia viral. Sin embargo, no fue hasta su tercer gran salto con la pandemia del SARS-CoV-2 que el foco de toda la comunidad científica se centró en ellos. Existen diversos saltos interespecies reportados en medicina veterinaria que no son más que intentos de los coronavirus de perfeccionar su potencial de transmisión para llegar a más de 7 mil millones de huéspedes en quienes replicar. Este artículo describe las características morfológicas y genéticas de los coronavirus, su particular mecanismo de replicación y cómo este influye en su diseminación. Del mismo modo, se describen signos clínicos, lesiones, variantes antigénicas y control mediante vacunación de los principales coronavirus asociados a diferentes especies animales, con un especial énfasis en los antecedentes reportados sobre coronavirus en América Latina.A 120 nm viral particle has completely modified what happens in a 12,000 km diameter planet. The first epidemics caused by the severe acute respiratory syndrome (SARS) coronavirus and the Middle East respiratory syndrome (MERS) coronaviruses, alerted to the potential for inter-species transmission. However, it was not until coronaviruses´ third big leap with the new SARS-CoV-2 pandemic that the the entire scientific community focused on them. There are several interspecies jumps reported in veterinary medicine that are nothing more than different coronaviruses attempts to perfect their transmission and potentially reach more than 7 billion hosts in which they can replicate. This article describes morphological and genetic characteristics of coronaviruses, their particular replication mechanism and how it influences their dissemination. In addition, clinical signs, lesions, antigenic variants and vaccination control of the main coronaviruses associated with different animal species are described, with a special emphasis on reports in Latin America.Fil: Colina, Santiago Emanuel.

First isolation and molecular characterization of Suid herpesvirus type 1 from a domestic dog in Argentina

Since Aujeszky's disease (pseudorabies), which is caused by Suid herpesvirus type 1 (SuHV-1), was first notified in Argentina in 1978, many SuHV-1 strains have been isolated from swine. However, this disease can affect other vertebrates, such as dogs (secondary hosts), and lead to fatal neurological disease. The objective of the current work is to report the first isolation and molecular characterization of SuHV-1 from a dead domestic dog from Santa Fe Province (Argentina), which had had nervous signs compatible with pseudorabies. Samples of brain and trigeminal ganglia from this dog were obtained and fixed in formol for histopathology, and virology studies were conducted after cell disruption. Supernatants of both samples were inoculated onto RK13 cells and, after 72 h, DNA was extracted with phenol-chloroform. Purified DNA was cut with a restriction enzyme and subjected to agarose gel and an aliquot was used to amplify the gD and gC genes by PCR. The gC sequence was compared with other public sequences. The strain isolated from the dog was similar to other Argentinean swine strains.Fil: Serena, Maria Soledad. Universidad Nacional de La Plata. Facultad de Ciencias Veterinarias.

Characterization of new strains of Pseudorabies virus in Argentina: Detection of interspecies transmission

Background: Aujeszky's disease is mainly a swine disease, still endemic worldwide. It can infect other mammalians, including human beings, and it is usually fatal with nervous symptoms. Ever since the disease was detected in 1988 in Argentina, many outbreaks have been reported involving both feral swine and dogs. Aim: At present, in Argentina, Pseudorabies virus (PRV) cases are sporadically reported; however, clinical cases are informed. This study aims to obtain information about the seroprevalence of PRV in wild boars and to isolate and characterize PRV from clinical samples. Methods: From 2018 to 2019, 78 wild boars’ serum samples from Bahía de Samborombón natural reserve were analyzed for antibodies to PRV using a virus neutralization test. Clinical samples from 17 pigs, 2 wild boars, 1 dog, and 1 cat were collected from 2013 to 2019 for viral isolation and detection of the presence of the gD gene by PCR. For sequence analysis, the gC partial gene was amplified. Results: Five strains were isolated from the dog, cat, and swine samples. The new PRV strains identified were confirmed by BLAST analysis, which revealed between 99.74% and 100% of similarity to the NIA-3 strain and phylogenetic analysis of the partial gene encoding the gC protein revealed that the PRV strains have divided into two main clades, clade 1 and clade 2. Conclusion: This report informed that most new cases of PRV were detected in the central regions of Argentina, where pig production is concentrated. The study in Bahía de Samborombón revealed a high percentage of detection but, the sampling is not representative of that of the rest of the country. Therefore, a systematic sampling effort of wild boar throughout the country should be included in the national program control. Although in Argentina only the inactivated Bartha vaccine is allowed, recombination risk should not be ignored if attenuated vaccines are incorporated into the National control plan. The two strains, one from the cat and one from the dog sample, are directly related to infected swine. The information about clinical cases and molecular characterization of new strains is important for a better understanding of the dynamics of PRV and to promote preventive measures.Fil: Serena, Maria Soledad.

First detection and genetic characterization of porcine circovirus type 3 (PCV3) in Argentina and its association with reproductive failure

Porcine circovirus type 3 (PCV3) is considered a new circovirus and since it first description has been widely reported in most of the swine-producing countries. Multisystemic inflammation and reproductive failure are consistent and concerning issues associated with PCV3 infection. This report describes the clinical and pathological features of a chronic reproductive disorder in a swine herd in Argentina associated with the presence of PCV3. Mummified (n = 42) and stillborn piglets (n = 20) from a case of chronic reproductive disorder (Study A) and mummified and stillborn piglets (n = 141) from normal deliveries (Study B) were retrospectively assessed for the presence of multiple reproductive pathogens (PCV3, PCV2, ADV, PPV, Leptospira spp. and Brucella spp). On study, A PCV3 and PPV were detected in 15 and 8 pools, respectively, with a coinfection rate of 100% in all PPV-positive cases. Three out of 131 foetuses from three different sows from Study B were positive only for PCV3. Histological evaluation of hearts from stillborn also showed lesions similar to those previously described in the literature for PCV3-reproductive disease. Partial genome of PCV3 was amplified and phylogenetic analysis showed that strains of Study A and B clustered within the PCV3a and PCV3b clades, respectively. This study demonstrates, for the first time, the PCV3 has been circulating in Argentina at least since 2016 and its potential role in reproductive disorders. Further studies are warranted to determine the role of PCV3 in the reproductive disease complex and its prevalence in the swine industry in Argentina.Fil: Serena, Maria Soledad.

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Measuring collective action intention toward gender equality across cultures

Collective action is a powerful tool for social change and is fundamental to women and girls’ empowerment on a societal level. Collective action towards gender equality could be understood as intentional and conscious civic behaviors focused on social transformation, questioning power relations, and promoting gender equality through collective efforts. Various instruments to measure collective action intentions have been developed, but to our knowledge none of the published measures were subject to invariance testing. We introduce the gender equality collective action intention (GECAI) scale and examine its psychometric isomorphism and measurement invariance, using data from 60 countries (N = 31,686). Our findings indicate that partial scalar measurement invariance of the GECAI scale permits conditional comparisons of latent mean GECAI scores across countries. Moreover, this metric psychometric isomorphism of the GECAI means we can interpret scores at the country-level (i.e., as a group attribute) conceptually similar to individual attributes. Therefore, our findings add to the growing body of literature on gender based collective action by introducing a methodologically sound tool to measure collective action intentions towards gender equality across cultures
