- Abstract
Peppermint is a medicinal plant, being an interesting income item, however it is susceptible to water deficit, this being the main cause of the low yields of this item in plots without an irrigation system. With the objective of evaluating productive and economic parameters of peppermint with organic and inorganic soil covers, this research was carried out in a completely randomized design, composed of five treatments (soil without cover, black mulching, white mulching, rice husk and patcholí grass) and four repetitions, totaling 20 experimental units. The variables evaluated were: length of basal shoots, number of basal shoots and lateral shoots, yield of fresh and dry mass, cost/benefit profitability of each type of coverage. All means were subjected to the analysis of variance (ANAVA) and the means were compared by the Tukey Test at 5%. Regarding the length of basal shoots, the best results were with black mulching, followed by white mulching and patchouli grass; the greatest number of lateral shoots with 16.45 with the white mulching, on the other hand, in the number of basal shoots, the control had the highest number with 4.15. The white mulching presented a higher yield than the control for the fresh mass with 1,544 kg ha-1 and dry mass of 628 kg ha-1. When analyzing the profitability in the fresh mass of peppermint, the use of white mulching was more feasible and in dry mass they showed negative profitability for white mulching., La menta piperita es una planta medicinal, su cultivo es considerado un interesante rubro de renta, sin embargo, es susceptible al déficit hídrico, siendo ésta la causa principal de los bajos rendimientos de este cultivo en parcelas sin sistema de riego. Con el objetivo de evaluar parámetros productivos y económicos del cultivo de menta piperita con coberturas orgánicas e inorgánicas de suelo que ayuden reducir el déficit hídrico, se llevó a cabo esta investigación en un diseño completamente al azar, compuesto por cinco tratamientos (suelo sin cobertura, mulching negro, mulching blanco, cascarilla de arroz y pasto pacholí) y cuatro repeticiones, totalizando 20 unidades experimentales. Las variables evaluadas fueron: longitud de brotes basales, cantidad de brotes basales y brotes laterales, rendimiento de masa fresca y seca. Adicionalmente, se analizó la rentabilidad de cada tipo de cobertura. Todas las medias fueron sometidas al análisis de varianza (ANAVA) y comparadas por el Test de Tukey al 5%. En cuanto a la longitud de brotes basales, los mejores resultados fueron con la utilización de mulching negro, seguido por el mulching blanco y pasto pacholí; la mayor cantidad de brotes laterales con 16,45 con el mulching blanco, en cambio en la cantidad de brotes basales fue el testigo que presentó una mayor cantidad con 4,15. El mulching blanco presentó mayor rendimiento que el testigo para la masa fresca y masa seca con 1.544 kg ha-1 y 628 kg ha-1, respectivamente. Al analizar la rentabilidad en la masa fresca de la menta piperita, la utilización del mulching blanco fue más factible, mientras que en masa seca se observó una rentabilidad negativa para todos los tratamientos., A hortelã-pimenta é uma planta medicinal, seu cultivo é considerado um item de renda interessante, no entanto, é suscetível ao déficit hídrico, sendo esta a principal causa da baixa produtividade dessa cultura em parcelas sem sistema de irrigação. Com o objetivo de avaliar parâmetros produtivos e econômicos do cultivo de hortelã-pimenta com coberturas orgânicas e inorgânicas do solo que auxiliam na redução do déficit hídrico, este trabalho foi conduzido em delineamento inteiramente casualizado, composto por cinco tratamentos (solo sem cobertura, cobertura morta preta, cobertura morta branca, casca de arroz e capim pachili) e quatro repetições. totalizando 20 unidades experimentais. As variáveis avaliadas foram: comprimento da parte aérea basal, número de brotações basais e laterais, produção de massa fresca e seca. Adicionalmente, foi analisada a rentabilidade de cada tipo de cobertura. Todas as médias foram submetidas à análise de variância (ANAVA) e comparadas pelo teste de Tukey de 5%. Em relação ao comprimento da parte aérea basal, os melhores resultados foram com o uso da cobertura morta preta, seguida da cobertura morta branca e do capim pachili; o maior número de brotações laterais com 16,45 com cobertura branca, enquanto no número de brotações basais foi o controle que apresentou o maior número com 4,15. A cobertura morta branca apresentou maior produtividade que a testemunha para massa fresca e massa seca com 1.544 kg ha-1 e 628 kg ha-1, respectivamente. Ao analisar a rentabilidade na massa fresca de hortelã-pimenta, o uso da cobertura morta branca foi mais viável, enquanto que na massa seca observou-se rentabilidade negativa para todos os tratamentos.

- Abstract
Norovirus (NoV) is the leading cause of outbreaks of acute gastroenteritis worldwide. These are non-enveloped viruses that are classified into 10 genogroups, of which genogroup I (GI), II (GII), IV (GIV), VIII (GVIII), and IX (GIX) are the ones that infect humans. Two outbreaks (A and B) of acute gastroenteritis that occurred in a nursery school are described. The first outbreak (A) occurred in November 2018, and the second (B) in February 2020. The detection of viral and bacterial pathogens was performed to study both outbreaks. Additionally, an epidemiological investigation of the outbreaks was conducted. In the analyzed fecal and vomit samples from both children and adults in the nursery school, NoV GII.4 [P16] Sydney 2012 and NoV GI.3 [P13] were detected in outbreaks A and B, respectively. Since the study of acute gastroenteritis outbreaks is underestimated in Argentina, it is necessary to design prevention, study, and control protocols, as well as to improve the outbreak notification system in our country., (Copyright © 2024 The Author(s).
