In the case of the smallest viruses, the final structure is simple and quite regular. Larger viruses with more proteins at their disposal can build more elaborate structures. Enveloped viruses may be quite regular in construction or may have irregular features, because the use of lipid envelopes ...
An important application of One Health is the quantitative and qualitative analysis of viruses in the aquatic environment, which has been long established for the purpose of identifying diffuse pollution sources (e.g., from untreated sewage) in water quality monitoring [5]. While culture-based meth...
Levels of anti-SARS-CoV-2 sIgA have been measured in a number of studies. For example, Isho B. et al. reported that in COVID-19 patients, salivary sIgA antibody responses to the receptor-binding domain (RBD) of the S protein measured long after recovery (up to 115 days) were higher...
Coronaviruses are the largest group of viruses which belongs to the family Coronaviridae, usually causing respiratory diseases. There are 7 types of coronaviruses in humans, four of which are human coronaviruses (HCoV-NL63, HCoV-229E, HCoV-OC43 and HKU1), which cause limited mild respiratory...
(SEMED) by providing consent to develop the project in schools. We also appreciate the support of the FIOCRUZ Genomic Surveillance Network (http://www.genomahcov.fiocruz.br/) members, the Respiratory Viruses Genomic Surveillance Network of the General Laboratory Coordination (CGLab) and the ...
The Mann–Whitney U test demonstrated the significantly greater body weight of rodents collected from the polluted site versus the control site. In contrast, the t test showed that the estimated age of animals was significantly higher in the control site versus the polluted site. The measured ...
2. Viruses Overview Viruses are obligate intracellular parasites; hence, they need to enter a cell to be able to replicate. The basic structure of a virus consists of a genome (either DNA or RNA) that is surrounded by a protein capsid and, in the case for most animal viruses, a lipid ...
Europe and the United States have entered the endemic stage of the COVID-19 outbreak: the virus is widespread, is significantly less fatal than it was in 2020, and is spurring only limited changes in public behavior. These endemic conditions are likely to continue through the summer and autu...
These viruses are distributed worldwide affecting both domestic and wildlife mammals [2]. In dogs, CPV is an important enteric pathogen because of the associated high morbidity and mortality rates [3]. It can affect dogs of any age, but severe infections are most likely to occur between 6...
The blood–brain barrier (BBB) is a sophisticated structure whose full functionality is required for maintaining the executive functions of the central nervous system (CNS). Tight control of transport across the barrier means that most drugs, particularly large size, which includes powerful biologicals...
