Serological and molecular evaluation of Senecavirus A (SVA) in pigs from farrow-to-finish farms in Minas Gerais, BrazilNARA Subscribed
The emergence of Senecavirus A (SVA) as a causative agent of vesicular diseases in pigs is noteworthy, since it was identified in 2014 through outbreaks in Brazil. The SVA belongs to the Picornaviridae family and is a non-enveloped virus with the ability to adapt to the environment. As the virus’s stability allows it to persist on farms post-outbreak, maintaining stringent biosecurity measures is crucial for effective control....
Bacterial diseases associated with the Mollicutes class can lead to decreased milk production and reproductive disorders in cattle, causing significant economic losses and compromising animal welfare. This study aimed to investigate the presence of Mollicutes and Ureaplasma diversum in the reproductive tract of dairy cows and determine the associated risk factors, as well as identify circulating strains of Ureaplasma in herds....
Influence of Population Density and Land Use on Microplastics in Urban Stormwater RunoffNARA Subscribed
Urban stormwater runoff is an important pathway for transporting microplastics (MPs) from urban environments to marine ecosystems. However, studies investigating how socio-spatial characteristics influence MP abundance and composition remain scarce, particularly in South America. This study evaluated the influence of population density and land use on MP abundance and morphology in stormwater runoff in the coastal zone of Fort...
The anesthetic management of female dogs with mammary neoplasia, usually classified as ASA II and undergoing invasive procedures such as mastectomy and ovariohysterectomy, requires effective sedation and anesthetic stability due to the increased anesthetic risk associated with advanced age and underlying disease. In this context, this study aimed to evaluate the sedative effects and reduction in anesthetic requirements of a fu...
Candida parapsilosis sensu stricto has emerged as a major cause of healthcare-associated candidemia, with increasing reports of fluconazole resistance worldwide. This resistance is most commonly associated with amino acid substitutions in Erg11p, particularly Y132F; however, regional variation in resistance mechanisms and clonal dissemination remains not fully understood. This study investigated the molecular epidemiology and...
Toxicity and repellency of the monoterpenoids carvone and eucalyptol on Sitophilus zeamais: contact and fumigation-based interactionsNARA Subscribed
Corn is a globally important crop; however, pest infestations during storage represent a major challenge. The maize weevil, Sitophilus zeamais (Coleoptera: Curculionidae), is a primary pest of stored maize, commonly controlled through phosphine fumigation. Nevertheless, extensive reliance on this insecticide has led to the emergence of resistant populations. Thus, the objective of this study was to evaluate the contact and fum...
Biomass and Spore Yield of Cercospora aff. canescens by Submerged Fermentation: Defining and Optimizing Culture ConditionsNARA Subscribed
Morningglory species ( Ipomoea spp.) are important weeds in Brazilian agriculture, particularly in non-burning sugarcane farming system. The fungus Cercospora aff. canescens has been selected as potential mycoherbicide; however, inoculum production is considered a challenge. The purpose of this study was to define and optimize culture conditions for biomass and spore yield of Cercospora aff. canescens CMAA 1444 in submerged fe...
Bokermannohyla frogs comprise species distributed across different Brazilian biomes, several of which are currently listed as endangered species. These anurans host a diversity of parasites that may negatively affect their survival. Several tick species of the family Argasidae and chigger mites of the family Leeuwenhoekiidae exhibit host specificity toward this group. Here, we report a case of co-parasitism by argasid ticks an...
Phoresy, a common dispersal strategy among arthropods, involves complex relationships between hosts and symbionts that influence ecological dynamics. Investigating the structure of phoretic mite communities and their population fluctuations is particularly relevant for widely distributed agricultural pests, such as the coconut palm weevil, Rhynchophorus palmarum . This study investigated the community of phoretic mites associa...
Connectivity and phylogenetic diversity of a fish metacommunity in subtropical coastal lakesNARA Subscribed
Neotropical freshwater biodiversity is remarkable, mainly due to historical, biotic, and environmental processes. Landscape connectivity can promote or restrict species dispersal in fish metacommunities, thereby influencing the diversity and phylogenetic structure of communities. This study evaluated whether structural landscape variables of the Tramandaí River basin affect the phylogenetic diversity of the component communiti...
Carbapenemase-producing Enterobacterales (CPE) pose a significant public health concern due to the limited therapeutic options and increasing dissemination outside clinical settings. Wastewater treatment plants (WWTPs) have been proposed as relevant environmental reservoirs for antimicrobial-resistant bacteria and mobile genetic elements. In this study, we performed genomic characterization of CPE strains recovered from raw wa...
The increasing utilization of agro-industrial waste underscores the necessity for sustainable valorization strategies consistent with circular economy principles. In this study, corn husk residue was investigated as a precursor to produce chemically activated biochars with tunable surface chemistry and porosity, enabling targeted adsorption of the cationic dye methylene blue (MB) and the anionic dye methyl orange (MO). Two act...
