Abstract
Capybara (Hydrochoerus hydrochaeris) is the world's largest rodent species distributed throughout South America. These animals are incredibly tolerant to anthropogenic environments and are occupying large urban centers. Capybaras are known to carry potentially zoonotic agents, including R. rickettsia, Leishmania spp., Leptospira spp., Trypanosoma spp., Salmonella spp., Toxoplasma gondii, and rabies virus. Focusing on the importance of monitoring potential sources of emerging zoonotic viruses and new viral reservoirs, the aim of the present study was to assess the presence of fecal-borne viruses in the feces of capybaras living in urban parks in São Paulo state, Brazil. A total of 337 fecal samples were collected between 2018 and 2020 and screened for the following: (i) Rotavirus group A (RVA) by ELISA; (ii) non-RVA species and Picobirnavirus (PBV) using PAGE; (iii) Human Bocaparvovirus (HBoV), Bufavirus (BuV), Tusavirus (TuV), and Cutavirus (CuV) qPCR; (iv) Human Enterovirus (EV), Norovirus GII (NoV), and Hantavirus by in houses RT-qPCR; (v) SARS-CoV-2 via commercial RT-qPCR kit assay; and (vi) Astrovirus (AstV) and Adenovirus (AdV) using conventional nested (RT)-PCRs. All fecal samples tested were negative for fecal-borne viruses. This study adds further evidence that the fecal-borne viruses is a minor public health issue in Brazilian capybaras, at least during the surveillance period and surveyed areas. Continuous monitoring of sylvatic animals is essential to prevent and control the emergence or re-emergence of newly discovered virus as well as viruses with known zoonotic potential.

Abstract
Hand-foot-and-mouth disease (HFMD) is a highly contagious viral disease commonly
associated to Enteroviruses (EV). During 2018, Brazil faced massive HFMD
outbreaks spread across the country. This study aimed to characterize the EV
responsible for the HFMD outbreak that occurred in Paraiba State, Brazilian
Northeastern region, in 2018, followed by a phylogenetic analysis to detail
information on its genetic diversity. A total of 49 serum samples (one from each
patient) collected from children ≤ 15 years old, clinically diagnosed with HFMD
were tested for EV using conventional RT-PCR and RT-qPCR. EV infection was
confirmed in 71.4% (35/49) of samples. The mean and median ages were 1.83 years
and one year old, respectively. Twenty-two EV-positive samples were successfully
sequenced and classified as EV-A species; 13 samples were also identified with
the CV-A6 genotype. The phylogenetic analysis (VP1 region) of three samples
revealed that the detected CV-A6 strains belonged to sub-lineage D3. The CV-A6
strains detected here clustered with strains from South America, Europe and West
Asia strains that were also involved in HFMD cases during the 2017-2018 seasons,
in addition to the previously detected Brazilian CV-A6 strains from 2012 to
2017, suggesting a global co-circulation of a set of different CV-A6 strains
introduced in the country at different times. The growing circulation of the
emerging CV-A6 associated with HFMD, together with the detection of more severe
cases worldwide, suggests the need for a more intense surveillance system of
HFMD in Brazil. In addition, this investigation was performed exclusively on
serum samples, and the analysis of whole blood samples should be considered and
could have shown advantages when employed in the diagnosis of enteroviral HFMD
outbreaks.

Abstract
This study combined conventional epidemiology of human astroviruses. From 2010 to 2016, 232 stool samples from children under 5 years of age were screened using NGS and conventional RT-PCR followed by genetic analysis in order to investigate the genotypic diversity of classical human astrovirus (HAstV) circulating in Tocantins State, Brazil. HAstV was detected in 16 cases (6.9%). Seven specimens (43.7%; 7/16) were positive according RT-PCR and next-generation sequencing (NGS) to investigate the molecular to both NGS and RT-PCR. NGS and RT-PCR individually revealed six (37.5%; 6/16) and three (18.8%; 3/16) additional positive samples, respectively. Sequencing of the HAstV-positive samples revealed HAstV-1a (9/16), HAstV-4c (3/16), and HAstV-5c (4/16) lineages.

Abstract
Human adenovirus (HAdV) is recognized as frequent cause of acute gastroenteritis and enteric viruses can be preserved in frozen stored feces for long periods of times. The purpose of the present study was to investigate enteric HAdV genotypic diversity in archival fecal specimens stored from 1998 to 2005 in order to understand the natural history of HAdV in diarrheal patients in Brazil before rotavirus vaccine introduction. A total of 3346 specimens were tested for HAdV using conventional PCR. Genotypes were identified by sequencing. HAdV was detected in 6.8% (228/3346). Positivity was higher in children ≤ 5 years and males (p < 0.05). HAdV was most frequently observed during winter and spring seasons (p < 0.05). HAdV-F41 was the most prevalent genotype (59.2%;135/228), followed by HAdV-F40 (16.2%;37/228), HAdV-C1 (5.2%;12/228), HAdV-C2 (5.2%;12/228), HAdV-C5 (3.1%;7/228), HAdV-A12 (1.3%;3/228), HAdV-E4 (0.9%;2/228), HAdV-B3 (0.9%;2/228) and HAdV-B21 (0.4%;1/228). In 7.6% (17/228) only species D could be defined. HAdV-E4 strains were phylogenetic analyzed and classified as lineage (a)-like PG II. HAdV prevalence remained stable in Brazilian population, regardless rotavirus vaccine introduction. The predominant HAdV genotypes detected did not change over time, highlighting a high diversity of circulating strains in the country throughout decades. Due to the historical lack of HAdV genotyping surveillance in Brazil, HAdV-E4 epidemiology is virtually unknown in the country. The present study contributed significantly to the understanding of the natural history of HAdV in diarrheal patients in Brazil. The acquired data are important for clinical diagnosis, particularly for studies investigating enteric viruses' prevalence and molecular epidemiology of archival clinical specimens.

Abstract
During 2006-2011, 5035 fecal samples were tested by PCR for human adenovirus (HAdV) and sequenced. HAdV was detected in 198 cases (3.9%), with the highest rate in children ≤ 5 years. Enteric HAdVs were the most prevalent genotypes (78%; 146/187): HAdV-F41 (63.6%; 119/187), HAdV-F40 (12.3%; 23/187), HAdV-A12 (1.6%; 3/187) and HAdV-A31 (0.5%; 1/187). Non-enteric HAdVs were detected in 22% (41/187): HAdV-C1 (8.0%; 15/187), HAdV-C2 (6.9%; 13/187), HAdV-C5 (4.3%; 8/187), HAdV-D8 (1.3%; 2/187), HAdV-B21 (0.5%; 1/187), HAdV-B3 (0.5%; 1/187) and HAdV-C6 (0.5%; 1/187). This 6-year retrospective study points out a high diversity of HAdV types circulating in Brazil and highlights the need to carry out molecular epidemiological studies of HAdV among patients with acute diarrheal infection on a regular basis.
