Human Adenovirus (HAdV) and Human Bocavirus (HBoV) are frequently found in different water sources throughout the year. Due to their health impact on humans, continuous monitoring of these viruses is one of the important tools to evaluate their circulation within the society. This study aimed to investigate the prevalence of HAdV and HBoV in differ...

Concentration and Detection of Enteric Viruses in Aqueous Samples

Background Human Adenovirus (HAdV) and Human Bocavirus (HBoV) are frequently found in different water sources throughout the year. Due to their health impact on humans, especially children, continuous monitoring of these viruses is one of the important tools to evaluate their circulation within society. This study aimed to investigate the prevalenc...

Upon the tremendous spread of coronavirus, there is a need to develop biodegradable, multifunctional, antiviral masks that can be safely used without polluting the environment as conventional surgical masks do. In this study, a three-layered mask filter is designed and fabricated. The first two layers contain electrospun polyamide with dispersed na...

Susceptibility to diseases is inherited and can be transmitted between populations. Single-nucleotide polymorphism (SNPs) in genes related to immune response is associated with diseases in cattle. This study investigated SNPs in the genomic region of cytokines in 702 samples of Curraleiro Pé-Duro cattle and associated them with the occurrence of an...

HAdV‐2 is considered a common agent of respiratory tract infection in the human, especially in children. Virus infection is believed to modify host cell expression necessary for its replication and therefore cell proteome can reflect the changes of specific cellular pathways during infection. This study aims to identify differentially expressed pro...

Human Adenoviruses (HAdVs) are etiological agents of different syndromes such as gastroenteritis, cystitis, ocular, and respiratory diseases, and infection by these viruses may cause alterations in cellular homeostasis. The objective of the study was the proteomic analysis of A-549 cells infected with HAdV-40 using LC–MS. At 30 h of infection, the...

Human Bocavirus (HBoV) has been identified from feces and respiratory samples from cases of both acute gastroenteritis and respiratory illness as well as in asymptomatic individuals. The aim of this study was to detect and characterize HBoV from fecal samples collected from hospitalized children aged less than five years old with no symptoms of res...

Resumo The purpose of this study was to perform a comparative analysis of Rotavirus A (RVA) G and P genotypes circulating in the Brazilian Mid-West in the period 1986-2015. Seven studies conducted from 1986 to 2009 were included, as well as fecal samples obtained in the period 2014-2015. RVA was screened by ELISA and/or PAGE; genotyping by convent...

The viral infection may cause a lot of modifications to the host cells. Determination of these changes can be observed from cell-virus relationship which is not important only in the direction of viral biology, but also at the cellular, which support to elucidate of various phenomena, including the discovery of new targets for antiviral therapy. In...

Arboviruses are transmitted by hematophagous arthropod vectors. They are maintained in nature through cycles involving vectors, hosts and their reservoirs, such as vertebrates, and are thus present in the wild environment. In Goiânia, an outbreak of yellow fever in 2007/2008, with records of epidemics, infections and death in the population of non-...

The mitochondria are involved in a variety of metabolic processes including cell ATP production, calcium homeostasis, cell proliferation, apoptosis, and synthesis of amino acid, nucleotide and lipid. The distribution, shape and operation of this organelle are regulated by intrinsic and extrinsic stimuli which may be a virus. These may induce or inh...

Gastroenteric viruses, such as rotavirus A (RVA), human adenovirus (HAdV), human calicivirus (norovirus and sapovirus), human astrovirus (HAstV), are important acute gastroenteritis agents. These agents affect mainly children, elderly, and immunocompromised individuals. Outbreaks of AGE are common in semiclosed environments, such as hospitals, scho...

Antimicrobial packaging, besides protecting the product from external environment, inhibits or retards microorganism growth in foods minimizing direct addition of preservatives and satisfying the actual demand of consumers for healthier foods, containing less additives. The objective of this study was to evaluate the antimicrobial efficiency of Whe...

Antimicrobial substances incorporated into edible films can control microbial contamination of foods by reducing the growth rate and/or inactivating target microorganisms. The aim of this work is to evaluate the antimicrobial activity of plant-derived essential oils EOs embedded into whey protein isolate WPI edible films. The EOs of cinnamon, cumin...
