RESUMO

In 2015, an episode of lymphocystis disease (LCD) was detected in wild and cultured populations of whitemouth croaker Micropogonias furnieri off the coast of Uruguay. Fish of both origins were collected for histopathological and molecular investigations. Macroscopically, multinodular tumorlike masses were observed in the skin. Histological examination of these masses revealed enlarged cells with a hyaline capsule and basophilic inclusion bodies in the cytoplasm. The inclusion bodies were further examined by electron microscopy and showed icosahedral virions with a median diameter of 182 nm. Routine molecular investigations targeting the DNA polymerase and major capsid protein genes showed the presence of the DNA of an unknown lymphocystis disease virus (LCDV) in all specimens showing external signs of LCD. Subsequently, 4 other core genes were amplified and sequenced from the viral genome. Phylogenetic tree reconstruction based on the concatenated sequence of 6 core genes indicated that the virus undoubtedly belongs to the genus Lymphocystivirus. However, the core gene sequences of the whitemouth croaker LCDV differ markedly from those of the 3 known LCDVs, putatively representing a fourth LCDV species.

RESUMO

other: Oral and oropharyngeal cancer is considered a public health problem in several countries due to its high incidence and mortality rate. OBJECTIVE: This study aimed to analyze oral and oropharyngeal cancer mortality in Uruguay from 1997 to 2014 by age, sex and country region. METHODOLOGY: A time series ecological study using secondary data was performed. Data on mortality due to oral and oropharyngeal cancers were obtained from the Vital Statistics Department of Uruguay's Ministry of Public Health. RESULTS: The cumulative mortality rate due to oral and oropharyngeal cancer over the study period was of 19.26/100,000 persons in women and 83.61/100.000 in men, with a mean annual rate of 1.75/100,000 in women and 7.60/100,000 in men. Mortality rate from both sites during the study period was 4.34 times higher in men than in women. Malignant neoplasms of other parts of the tongue and base of tongue showed the highest mortality rate. The means of the annual coefficients of deaths were higher for the age groups between 50 and 69 years. Higher mortality rates of oral and oropharyngeal cancer were observed in Artigas (4.63) and Cerro Largo (3.75). CONCLUSIONS: Our study described a high mortality rate for oral and oropharyngeal cancer in Uruguay from 1997 to 2014. According to the country's health department, men, tongue cancer, and oral cavity had higher mortality rates, with some variation. Prevention strategies with control of risk factors and early diagnosis are necessary to improve survival in the Uruguayan population.

RESUMO

Bovine viral diarrhea virus (BVDV) is a major pathogen worldwide, causing significant economic losses to the livestock sector. In Uruguay, BVDV seroprevalence at the farm level is >80%. In this work, 2546 serum, blood or tissue samples collected from animals suspected of being affected by BVD between 2015 and 2017 were analyzed by reverse transcription PCR and sequencing. Analysis of the BVDV genomic regions 5'UTR/Npro, Npro and E2 revealed that BVDV-1a, 1i and 2b circulate in the country, with BVDV-1a being the most prevalent subtype. Population dynamics studies revealed that BVDV-1a has been circulating in our herds since ~1990. This subtype began to spread and evolve, accumulating point mutations at a rate of 3.48 × 10-3 substitutions/site/year, acquiring specific genetic characteristics that gave rise to two local genetic lineages of BVDV-1a. These lineages are divergent from those circulating worldwide, as well as the vaccine strain currently used in Uruguay. The most notable differences between field and vaccine strains were found in the E2 glycoprotein, suggesting that the amino acid substitutions could result in failure of cross-protection/neutralization after vaccination. This is the first study that compares Uruguayan BVDV field and vaccine strains with other BVDV strains from throughout the world. The results obtained in this study will be very useful for developing a suitable immunization program for BVDV in Uruguay by identifying local field strains as candidates for vaccine development.

RESUMO

Objective: This study investigates the association between the prevalence and severity of dental fluorosis, the socio-economic status (SES) and area of residence among 12-year-old schoolchildren in Uruguay.Material and methods: The study was descriptive, cross-sectional, explanatory and observational. Subjects considered eligible were born in 1999 and had their parents' or guardian's prior consent. A questionnaire was used to identify SES according to Centro de Investigaciones Económicas Institute on four levels. Dental fluorosis was determined using the Thylstrup-Fejerskov (TF) index.Results: Of the 1544 students examined, 45.0% showed dental fluorosis. A TF index 1-2 was recorded in 29.3% of the subjects, TF 3 in 20.9%, TF 4 in 6.7% and TF 5-9 in 2.1%. In area 1 (the capital Montevideo city), 84.8% of the subjects had dental fluorosis, a value that was significantly higher than in the inland region (area 2, 24.4%) and border departments (area 3, 22.5%) (x2 = 27.92, p < .0001). Students from families with a low socio-economic level showed less prevalence of dental fluorosis than those with a high level (x2 = 14.58, p = .002).Conclusion: Significant differences exist in the prevalence of dental fluorosis in relation to place of residence and socio-economic level.

RESUMO

Neospora caninum causes neosporosis, a leading cause of bovine abortion worldwide. Uruguay is a developing economy in South America that produces milk to feed seven times its population annually. Naturally, dairy production is paramount to the country's economy, and bovine reproductive failure impacts it profoundly. Recent studies demonstrated that the vast majority of infectious abortions in dairy cows are caused by N. caninum. To delve into the local situation and contextualize it within the international standing, we set out to characterize the Uruguayan N. caninum strains. For this, we isolated four distinct strains and determined by microsatellite typing that these represent three unique genetic lineages, distinct from those reported previously in the region or elsewhere. An unbiased analysis of the current worldwide genetic diversity of N. caninum strains known, whereby six typing clusters can be resolved, revealed that three of the four Uruguayan strains group closely with regional strains from Argentina and Brazil. The remaining strain groups in an unrelated genetic cluster, suggesting multiple origins of the local strains. Microsatellite typing of N. caninum DNA from fetuses opportunistically collected from local dairy farms correlated more often with one of the isolates. Overall, our results contribute to further understanding of genetic diversity among strains of N. caninum both regionally and worldwide.

RESUMO

Atopsyche is the largest genus of hydrobiosids, comprising 139 species in three subgenera (Atopsyche, Atopsaura, and Dolochorema), distributed from southwestern United States to northeastern Uruguay. Atopsyche (Atopsaura) is the most diverse subgenus with 65 species, Atopsyche (Atopsyche) with 51, and Atopsyche (Dolochorema) with three. This paper provides a taxonomic study of Atopsyche, including descriptions of A. (Atopsyche) bravoi n. sp. from Ecuador, A. (Atopsaura) beckeri n. sp. from Cuba, A. (Atopsaura) japi n. sp. from Brazil, and the redescription of A. (Atopsaura) usingeri. Additionally, the morphological variations of A. (Atopsaura) antisuya and A. (Atopsaura) diamantina are presented, as well new records. These results contribute to taxonomical knowledge of Atopsyche and increase the number of described species to 142.

RESUMO

Actinopus specimens from different localities in Uruguay that did not match any of the previously species present in the country were examined, and four new species are described: A. coboi sp. nov., from Colonia province; A. fernandezi sp. nov., from Salto province; A. simoi sp. nov., from Maldonado province; and A. uruguayense sp. nov., from Colonia and Cerro Largo provinces. The record of the species A. longipalpis for Montevideo is rejected and A. liodon is considered "species inquirenda". Actinopus coboi has spermathecae with an apical lobe diagonally directed; A. fernandezi is characterized by a stylized copulatory bulb and its greater number of retrolateral thorns on tibia II. Actinopus simoi can be distinguished from A. uruguayense by its carapace with a dark coloration; a reddish coloration in the palpal tibia and the shape of its spermathecae and copulatory bulb. With the presence of the Argentinian species-A. gerschiapelliarum, A. puelche and A. insignis-the number of species known in the country is increased to nine. All new species are diagnosed and illustrated; a dichotomous key to all species of Actinopus from Uruguay is also provided.

RESUMO

The new genus Guasuctenus gen. nov. is described based on the results of a recent phylogenetic analysis. This phylogeny, which included representatives of all Ctenidae subfamilies, showed that the genus Ctenus as currently defined, does not comprise a monophyletic group. The results indicated that several species are misplaced in Ctenus and should be transferred to new genera. Aiming to correct the placement of two species originally described in Ctenus, we propose the new genus Guasuctenus to accommodate those species and better represent their phylogenetic relationships. Guasuctenus is supported by the presence of a dorsal cymbial projection in the male palp. Previously regarded as a subspecies, Ctenus longipes vittatissimus Strand, 1916 is here ranked as species, and Guasuctenus longipes (Keyserling, 1891) new comb. and G. vittatissimus (Strand, 1916) new rank, new comb. are redescribed. Ctenus griseus Keyserling, 1891 is recognized as a junior synyonym of Ctenus longipes Keyserling, 1891. Lectotypes and paralectotypes of Guasuctenus vittatissimus (Strand, 1016) are designated for stability. The species of the genus are distributed in southern Brazil and Uruguay.

RESUMO

Human bocaviruses (HBoV) are mainly associated with respiratory and gastroenteric infections. These viruses belong to the family Parvoviridae, genus Bocaparvovirus and are classified in four subtypes (HBoV1-4). Recombination and point mutation have been described as basis of parvovirus evolution. In this study three viral sequences were obtained from positives HBoV sewage samples collected in two Uruguayan cities and were characterised by different methods as recombinant strains. This recombination event was localised in the 5' end of VP1 gene and the parental strains belonged to subtypes 3 and 4. These three Uruguayan strains are identical at the nucleotide sequences in the analysed genome region of the virus. As far as we known, this study represents the first detection of HBoV recombinants strains in the Americas.

RESUMO

Salmonella enterica is an important animal and human pathogen that can cause enteritis and septicaemia in calves. Generally, antibiotics are prescribed for the treatment of salmonellosis in dairy calves. Here, we report the isolation of antibiotic resistant S. enterica serotypes from calves, including multidrug-resistant isolates. A total of 544 faecal samples from live healthy and diarrheic dairy calves from 29 commercial dairy farms and organ samples from 19 deceased calves that succumbed to salmonellosis in 12 commercial dairy farms in Uruguay were processed for selective S. enterica culture. In total, 41 isolates were serotyped, and susceptibility to 14 antibiotics, from 9 classes of compounds, was evaluated by disk-diffusion test. The minimum inhibitory concentration (MIC) was determined by microdilution. Salmonella Typhimurium was the most frequent serotype, followed by S. Dublin and S. Anatum. Whether determined by diffusion assay or microdilution, resistance to tetracycline, streptomycin and ampicillin were the most frequently pattern found. Based on MIC, 5 isolates were resistant to at least one antibiotic, 21 were resistant to 2 antibiotics, and 14 were multidrug-resistant (resistant to at least one antibiotic in 3 different categories of antibiotics). Eleven different resistance patterns were found. Multidrug resistance in S. enterica is a concern for animal and public health not only because of its zoonotic potential but also due to the possibility of transfer resistance determinants to other bacterial genera. This represents the first report of the antibiotic resistance in S. enterica in dairy farms in Uruguay.

RESUMO

Este artigo tem como escopo estabelecer, a partir de pesquisa bibliográfica e documental, um comparativo legal entre o aporte jurisprudencial brasileiro (Ação Direta de Inconstitucionalidade nº 4.275-DF, Supremo Tribunal Federal do Brasil, 2018) e o Projeto de Lei nº 816/2017 (Ley Integral para Personas Trans), recentemente aprovado pela Câmara dos Deputados do Uruguai, a fim de combater a discriminação e ampliar direitos para transexuais, transgêneros e travestis no Brasil, considerando-se a necessidade de se expandir a cidadania para essas pessoas: tradicionalmente marginalizados. Busca-se discutir sobre as legislações dos dois países selecionados como objeto de pesquisa (integrantes do Mercosul), a fim de verificar se estão promovendo Direitos Humanos à População T. Como resultado, evidencia-se que, ao passo que o Uruguai tem empreendido esforços na positivação de direitos e no reconhecimento do respeito à autodeterminação da identidade de gênero, o Brasil, ainda, tem caminhado timidamente na mesma construção, dependendo ­ prioritariamente ­ de jurisprudências e atos administrativos para tanto.


The purpose of this article is to establish, based on bibliographical and documentary research, a legal comparison between the Brazilian jurisprudential contribution (Direct Unconstitutionality Action nº 4,275-DF, Supreme Federal Court of Brazil, 2018) and Bill nº 816/2017 (Ley Integral para Personas Trans), recently approved by the Chamber of Deputies of Uruguay, in order to combat discrimination and expand rights for transsexuals, transgenders and transvestites in Brazil, considering the need to expand citizenship for these people: traditionally marginalized. The aim is to discuss the legislation of the two countries selected as an object of research (members of Mercosur), in order to verify if they are promoting Human Rights to Population T. As a result, it is evident that, while Uruguay has made efforts in the positivation of rights and in the recognition of respect for the self-determination of gender identity, Brazil has also walked timidly in the same construction, depending - primarily on jurisprudence and administrative acts for that purpose.

RESUMO

Echinococcus granulosus is a cestode parasite whose cytoskeleton plasticity allows it to enter and develop inside its hosts, completing thus its life cycle. We focused our attention on F-actin organization and distribution in E. granulosus protoscoleces (PSC) in order to contribute to the knowledge of the parasite cytoskeleton. In particular, we addressed some aspects of F-actin rearrangements in PSC at different stages of the evagination/invagination process. The use of light microscopy allowed us to identify different PSC structures and phalloidin staining displayed a parasite's highly organized F-actin cytoskeleton. Suckers exhibit an important musculature composed of a set of radial fibers. At the rostellum, the F-actin filaments are arranged in a bulbar shape with perforations that appear to be the attachment places for the hooks. Also, "circular" structures of F-actin were identified, which remind the flame cells. Furthermore, parasite F-actin filaments, unevenly distributed, seem to have remained substantially unchanged during the evagination/invagination process. Finally, we showed that the scolex of an evaginated E. granulosus PSC reinvaginates in vitro without any treatment.

RESUMO

Bovine coronavirus (BCoV) is a recognized cause of severe neonatal calf diarrhea, with a negative impact on animal welfare, leading to economic losses to the livestock industry. Cattle production is one of the most important economic sectors in Uruguay. The aim of this study was to determine the frequency of BCoV infections and their genetic diversity in Uruguayan calves and to describe the evolutionary history of the virus in South America. The overall detection rate of BCoV in Uruguay was 7.8% (64/824): 7.7% (60/782) in dairy cattle and 9.5% (4/42) in beef cattle. The detection rate of BCoV in samples from deceased and live calves was 10.0% (6/60) and 7.6% (58/763), respectively. Interestingly, there was a lower frequency of BCoV detection in calves born to vaccinated dams (3.3%, 8/240) than in calves born to unvaccinated dams (12.2%, 32/263) (OR: 4.02, 95%CI: 1.81-8.90; p = 0.00026). The frequency of BCoV detection was higher in colder months (11.8%, 44/373) than in warmer months (1.5%, 3/206) (OR: 9.05, 95%CI: 2.77-29.53, p = 0.000013). Uruguayan strains grouped together in two different lineages: one with Argentinean strains and the other with Brazilian strains. Both BCoV lineages were estimated to have entered Uruguay in 2013: one of them from Brazil (95%HPD interval: 2011-2014) and the other from Argentina (95%HPD interval: 2010-2014). The lineages differed by four amino acid changes, and both were divergent from the Mebus reference strain. Surveillance should be maintained to detect possible emerging strains that can clearly diverge at the antigenic level from vaccine strains.

RESUMO

An outbreak of hypomagnesemia is reported in Holstein dairy cattle grazing lush oat (Avena sativa) pasture in Uruguay. Nine of 270 (3.3%) cows died in May-July (autumn-winter) 2017. These nine cows were from 2 to 9-years-old (1st-6th lactation), with 22 to 194 days of lactation and 15.8 to 31.4L of daily milk production. Two cows with acute sialorrhea, muscle spasms, lateral recumbency, weakness, opisthotonos, and coma, were euthanized and necropsied. No significant macroscopic or histological lesions were found. One untreated clinically-affected cow and eight out of 14 clinically healthy cows of the same group under similar management and production conditions had low serum levels of Mg (lower than 0.7mmol/L). Secondarily, both clinically affected cows and six out of 14 healthy cows had low serum Ca levels. The K/(Ca+Mg) ratio of two oat forages, corn silage, and ration was 5.10, 7.73, 2.45, and 0.85, respectively. A K/(Ca+Mg) ratio lower than 2.2 represents a risk for hypomagnesemia. The difference between the contribution-requirement of minerals in the diet was established and a daily deficiency of Mg (-0.36g/day), Na (-25.2g/day) and Ca (-9.27g/day) was found, while K (184.42g/day) and P (12.81g/day) were in excess. The diet was reformulated to correct the deficiencies and the disease was controlled by the daily administration of 80g of magnesium oxide, 80g of calcium carbonate and 30g sodium chloride per cow. It is concluded that hypomagnesemia is a cause of mortality in dairy cattle in Uruguay, and that the condition can be prevented by appropriate diet formulation.(AU)


Descreve-se um surto de hipomagnesemia em bovinos leiteiros da raça Holandês com alimentação a base de pastagens de aveia (Avena sativa) em crescimento no Uruguai, nos meses de maio a julho (outono-inverno) de 2017. De um rebanho de 270 vacas em ordenha, nove (3,3%) morreram. As nove vacas tinham entre dois e nove anos, estavam entre a primeira e a sexta lactação e a produção diária era de 15,8 a 31,4 litros de leite. Duas vacas que apresentaram sialorreia, espasmos musculares, decúbito lateral, debilidade, opistótono e posteriormente, estado comatoso foram eutanasiadas e necropsiadas. Não foram observadas lesões macroscópicas ou histológicas significantes. Uma vaca com sinais clínicos, não tratada, e oito de 14 vacas sem sinais clínicos, do mesmo rebanho, apresentaram baixos níveis séricos de Mg (menos de 0,7mmol/L). Adicionalmente, as duas vacas com sinais clínicos e seis das 14 vacas sem sinais clínicos apresentaram baixos níveis de Ca sérico. A relação do risco tetanizante K/(Ca+Mg) de duas pastagens de aveia, silagem de milho e ração concentrada foi estimada em 5; 10; 7,73; 2,15 e 0,85, respectivamente. Uma relação K/(Ca+Mg) maior de 2,2 é um indicador do potencial tetanizante da forragem, A diferença entre o aporte e os requerimentos dos minerais foi estabelecida constatando-se deficiência diária de Mg (-0,36g/dia), Na (-25,2g/dia) e Ca (-9,27g/dia). O potássio (K) (184,42g/dia) e o fósforo (P) (12,81g/dia) estavam em excesso. A dieta foi reformulada para corrigir as deficiências e a doença foi controlada mediante a administração diária de 80g de MgO, 80g de CaCO3 e 30g de NaCl por vaca. Conclui-se que a hipomagnesemia é uma doença de importância crescente em gado leiteiro no Uruguai e que deve ser prevenida mediante a formulação correta da dieta.(AU)
