RESUMEN
Paracoccidioidomycosis (PCM) is an endemic fungal disease that occurs in Latin America and primarily affects humans. The disease has been rarely documented in non-human primates. This report details a disseminated and fatal case of PCM caused by Paracoccidioides brasiliensis in a western black-handed tamarin (Saguinus niger) under human care. Histopathological examination revealed extensive pyogranulomatous inflammation in the lungs, spleen, liver, lymph nodes, kidneys, epididymis, right testicle, heart, adrenal gland and intestines, associated with characteristic yeast forms consistent with Paracoccidioides spp and confirmed by immunohistochemistry. Molecular analysis indicated a high nucleotide similarity with P. brasiliensis sequences for both the 18S rRNA and gp43 genes. This naturally occurring infection highlights the susceptibility of these animals to PCM and their role in ecoepidemiology warrants further investigation.

Emerald tree boas (Corallus batesii) are boids that in situ occurs in forested habitats in the Amazon Basin. The mycobacterial species can infect reptiles but the species Mycolicibacterium fortuitum was identified only in feces samples of ex situ Python regius and was isolated from granulomatous lesions of an ex situ Iguana iguana when was still part of the genus Mycobacterium. This article aims to report a mycobacteria infection case in a female Corallus batesii kept under human care. The animal presented apathy and 2 months of anorexia, being found dead. The necropsy revealed presence of tracheal and pulmonary nodules besides multifocal, bacterial, granulomatous pneumonia. After Fite-Faraco histochemical staining, immunohistochemistry, semi-nested polymerase chain reaction (PCR) and genetic sequencing the Mycolicibacterium fortuitum complex was diagnosed with 99.54% of nucleotide similarity. This mycobacterial species was already pointed out as an important nosocomial pathogen and more studies are necessary to explore their zoonotic potential.

This article aims to reflect on the images of childhood in videos featuring child YouTubers playing, analyzing the nature of play portrayed in them and its relationship with the child's right to play and be protected against any form of exploitation. METHOD: A documentary study of 100 videos shared on YouTube was conducted, subjected to categorical content analysis with an emphasis on the modes of participation of adults and children in dialogues with the platform's languages present in the videos. RESULTS AND DISCUSSION: The boundaries between children's artistic expression and child labor exploitation are becoming increasingly challenging, with legal discussions presenting difficulties in regulation due to the home environment and predominant parental control. The analysis reveals how the videos are perceived as standardized commodities, hiding the concrete work behind an image of apparent spontaneity. CONCLUSION: The research highlights contractual digital risks for children, focusing on those related to commercialization. The analyzed videos reflect an instrumentalization of the child's basic right to play, associated with market interests, an aspect that takes on the contours of child labor exploitation, compromising the freedom to play spontaneously.
RESUMEN
Coffee professionals have long known that the "roast profile," i.e., the temperature versus time inside the roaster, strongly affects the flavor and quality of the coffee. A particularly important attribute of brewed coffee is the perceived sourness, which is known to be strongly correlated to the total titratable acidity (TA). Most prior work has focused on laboratory-scale roasters with little control over the roast profile, so the relationship between roast profile in a commercial-scale roaster and the corresponding development of TA to date remains unclear. Here we investigate roast profiles of the same total duration but very different dynamics inside a 5-kg commercial drum roaster, and we show that the TA invariably peaks during first crack and then decays to its original value by second crack. Although the dynamics of the TA development varied with roast profile, the peak TA surprisingly exhibited almost no statistically significant differences among roast profiles. Our results provide insight on how to manipulate and achieve desired sourness during roasting.

BACKGROUND: The Vieira's titi monkey (Plecturocebus vieirai) was recently described and characterized as endemic to Brazil. According to the IUCN red list, this species is classified as critically endangered (CR). At the date of the publication of this manuscript, there are no published data on the health aspects of this species. METHODS: For this study, the necropsy, and histopathological data of the mortality of P. vieirai at Sorocaba Zoo (São Paulo, Brazil) were collected and analyzed. RESULTS: Causes of death diagnosed included disorders of the urinary, gastrointestinal, immune, and circulatory systems. CONCLUSIONS: This study provides information regarding the pathological conditions of P. vieirai and points to urinary and gastrointestinal diseases as the main causes of death in this species at Sorocaba Zoo. These results can help veterinarians who have this species under their care diagnose and deal with it more quickly, increasing the probability of survival.

Background: Failure of first-line regimens with dolutegravir, a high genetic barrier antiretroviral of the integrase inhibitor class, although uncommon, tends to increase in prevalence due to broader use. Objective: To describe the clinical case of an HIV/Tuberculosis coinfected patient who developed Human Immunodeficieny Virus (HIV) treatment failure during dolutegravir therapy. Case report: Male, 29 years old, presented with a right cervical mass, dry cough, and hyporexia, which lasted 2 weeks. Diagnostic tests were positive for tuberculosis and HIV. The viral load was 437,927 cp/mL (Log = 5.64). Antiretroviral therapy was initiated with Tenofovir/Lamivudine and Dolutegravir (TDF/3TC and DTG), the latter at a dose of 50 mg/day, as was a regimen for tuberculosis. After 8 months, therapeutic failure was verified. Genotyping was requested, with detection of the H51Y and E157Q mutations in the integrase. Conclusion: Attention when determining the antiretroviral therapy treatment regimen of HIV/TB coinfected patients is paramount. Poor adherence to antiretroviral therapy and follow-up may have contributed to treatment failure and resistance.
RESUMEN
Opossums are considered resistant to rabies. Nonhematophagous bats are reservoirs of rabies in urban areas of South America. We analyzed bats and opossums tested for rabies during 2021 in a highly urbanized city in Brazil to understand spillover in an urban setting. Wildlife surveillance is necessary to prevent rabies in humans and domestic animals.

Biosurfactants (BS) are becoming a solution for today's world since they are considered a reasonable and eco-friendly option for use in products that require surfactants. This study aimed to evaluate the antibacterial activity of purified fractions containing biosurfactants produced by the yeast Wickerhamomyces anomalus CCMA 0358 using waste cooking oil (WCO) as substrate. Mixed fractions were separated and characterized by TLC, MPLC, GC-MS, LC-OMS, LC-SQMS, FTIR, 1H, 13C, DEPT 135, COSY, HSQC, and HMBC. The results confirmed the presence of palmitic acid and oleic acid fatty acids, derived from the core biosurfactant structure; however, the core could not be identified. The crude biosurfactant and its purified fractions were evaluated against pathogenic bacteria, and the purified fractions of the biosurfactant are more efficient at inhibitory and bactericidal activities than the crude biosurfactant. To the best of our knowledge, this is the first study that evaluated the antimicrobial activity of purified fractions of biosurfactants produced by the species Wickerhamomyces anomalus. Therefore, the purification of biosurfactants can emerge as an interesting alternative to increase the bioactivity of the compounds and ensure greater efficiency and biotechnological employability. KEY POINTS: ⢠Successful production of a biosurfactant using a renewed carbon source. ⢠Evaluation of the antimicrobial activity of purified fractions of BS. ⢠Separated fractions of the BS are more efficient against bacteria than the crude BS.

Transmission of herpesvirus between humans and non-human primates represents a serious potential threat to human health and endangered species conservation. This study aimed to identify herpesvirus genomes in samples of neotropical primates (NTPs) in the state of São Paulo, Brazil. A total of 242 NTPs, including Callithrix sp., Alouatta sp., Sapajus sp., and Callicebus sp., were evaluated by pan-herpesvirus polymerase chain reaction (PCR) and sequencing. Sixty-two (25.6%) samples containing genome segments representative of members of the family Herpesviridae, including 16.1% for Callitrichine gammaherpesvirus 3, 6.1% for Human alphaherpesvirus 1, 2.1% for Alouatta macconnelli cytomegalovirus, and 0.83% for Cebus albifrons lymphocryptovirus 1. No co-infections were detected. The detection of herpesvirus genomes was significantly higher among adult animals (p = 0.033) and those kept under human care (p = 0.008671). These findings confirm the importance of monitoring the occurrence of herpesviruses in NTP populations in epizootic events.

This article presents an action-research project from the EU-funded SMOOTH project, which focuses on the potential of Educational Commons to address educational inequalities. The project adopts an emergent paradigm that views spaces for collaboration, content co-creation, socialization, governance, and play as catalysts for reversing inequalities. The action-research, conducted in a disadvantaged non-formal education setting in northern Portugal, involved children aged 8-10 years old. Over a span of 10 months, the innovative action-research program aimed to achieve several objectives: (1) reversing inequalities faced by vulnerable social groups, (2) strengthening inter-cultural and inter-generational dialogue and social integration, (3) developing essential social and personal skills, and (4) creating smooth spaces of democratic citizenship based on equality, collaboration, sharing, and caring. By understanding the tensions and conflicts that emerge in children's everyday situations, the project sought to build and foster community through embracing differences. This article analyzes the characteristics, behaviors, challenges, and strengths observed during the 30 sessions. The results provide insights into the dimensions of Children as commoners, in terms of sharing and care, cooperation and collective creativity and active citizenship. This research contributes to the exploration of Educational Commons as a means to promote equity and transform educational contexts.

The present case is the first description of a co-infection with canine distemper virus (CDV) and canine adenovirus type 1 (CAdV-1) in a free-living hoary fox pup from Brazil. The animal was found and rescued with poor body condition, dehydration, incoordination, ataxia, excessive vocalization, and "blue eyes" phenomenon. Despite the efforts, euthanasia was elected due to worsening clinical signs and poor prognosis. Pathologic examination revealed a mild, acute, random, necrotizing hepatitis, acute bronchopneumonia, hydrocephalus, corneal edema with epithelium degeneration, and acidophilic intracytoplasmatic inclusion bodies in different epithelial cells types with rare syncytial. Through immunohistochemistry, CDV antigen was observed in the tongue, trachea, lungs, liver, spleen, stomach, intestine and urinary bladder. Adenovirus antigen was identified in the nucleus of scattered hepatocytes. Polymerase chain reaction and sequencing demonstrated high similarity with CAdV-1 and wild-type strain of CDV close related to Brazilian viral lineages isolated from domestic dogs. Disease surveillance in wildlife animals is essential to assess possible conservation threats and consider the implementation of mitigation or control measures.

Ulcerative Colitis (UC) is an inflammatory disease characterized by colonic mucosal lesions associated with an increased risk of carcinogenesis. UC pathogenesis involves environmental and genetic factors. Genetic studies have indicated the association of gene variants coding for the divalent metal ion transporter SLC11A1 protein (formerly NRAMP1) with UC susceptibility in several animal species. Two mouse lines were genetically selected for high (AIRmax) or low (AIRmin) acute inflammatory responses (AIR). AIRmax is susceptible, and AIRmin is resistant to DSS-induced colitis and colon carcinogenesis. Furthermore, AIRmin mice present polymorphism of the Slc11a1 gene. Here we investigated the possible modulating effect of the Slc11a1 R and S variants in DSS-induced colitis by using AIRmin mice homozygous for Slc11a1 R (AIRminRR) or S (AIRminSS) alleles. We evaluated UC by the disease activity index (DAI), considering weight loss, diarrhea, blood in the anus or feces, cytokines, histopathology, and cell populations in the distal colon epithelium. AIRminSS mice have become susceptible to DSS effects, with higher DAI, IL6, G-CSF, and MCP-1 production and morphological and colon histopathological alterations than AIRminRR mice. The results point to a role of the Slc11a1 S allele in DSS colitis induction in the genetic background of AIRmin mice.
