Tick-borne pathogens in meat sheep from Brazil: first report of Theileria ovis in sheep in latin America Mário Felipe Alvarez Balaro, Matheus Dias Cordeiro, Isadora de Fátima Braga Magalhães, Júlia Cardoso Pereira, Bruna de Azevedo Baêta, Alexandro Guterres, Cláudia Bezerra da Silva, Nathalie Costa da Cunha Parasitology Research, 2026 Tick-borne hemoparasitic diseases have a worldwide presence, impacting public health and livestock economies. In this study, 16 ewes from the same farm were evaluated, 56% (9/16) exhibited various clinical symptoms, such as conjunctivitis, nasal discharge, cough, swollen lymph nodes, fever, and tick infestation. After physical examination, ultrasound and complete blood count analysis were performed, along with molecular testing using Polymerase Chain Reaction (PCR) and Sanger sequencing. Neutrophilic leukocytosis, mild normocytic normochromic anemia, thrombocytosis, reactive lymphocytes, and intra-cytoplasmic lymphocytic inclusion bodies were all identified. Spleen and liver abnormalities were confirmed by ultrasound. In total, 44% (7/16) of ewes were infested with ticks, which were identified as Dermacentor nitens, Rhipicephalus microplus, and Amblyomma sculptum. Of the 16 sheep screened for tick-borne agents using PCR, 37% (6/16) tested positive for the Piroplasmida order. Among these, 33% (2/6) showed co-infection with Anaplasma sp. None of the samples tested positive for Ehrlichia spp. or Borrelia spp. Molecular analyses, followed by sequence comparison, revealed the pathogens to be Theileria ovis and Anaplasma sp. closely related to Candidatus Anaplasma boleense. Ewes were treated with three doses of oxytetracycline (20 mg/kg) 48 h apart. After treatment, new blood smears and whole blood samples were negative for cell inclusions, and all PCR results were negative. The study identified a tick-borne disease caused by piroplasms and Anaplasma spp. in a Brazilian sheep flock with clinical remission following treatment. Furthermore, this research marks the first documentation of T. ovis and Anaplasma sp. closely related to Candidatus A. boleense infecting sheep in Latin America, emphasizing the need for further studies and surveillance of tick-borne pathogens in Brazil.
Detection of Lymphocytic Choriomeningitis Virus in House Mouse (Mus musculus) in Brazil Gabriel Rosa Cavalcanti, Jorlan Fernandes, Fernando de Oliveira Santos, Bernardo Rodrigues Teixeira, Alexandro Guterres, Julia Brignone, Silvana Levis, Camila dos Santos Lucio, Sócrates Fraga da Costa-Neto, Vagner Fonseca, Marta Giovanetti, Luiz Carlos Junior Alcantara, Paulo Sérgio D’Andrea, Elba Regina Sampaio de Lemos, Renata Carvalho de Oliveira Viruses, 2025 The lymphocytic choriomeningitis virus (LCMV) is an under-investigated rodent-borne arenavirus primarily associated with its natural reservoir, the cosmopolitan rodent Mus musculus. Although widely distributed in mice worldwide, human cases are rare, likely under-reported, and often misdiagnosed. While typically asymptomatic or self-limiting, infection can progress to neurological disease, severe congenital outcomes, or fatal illness in transplant recipients. Despite its public health relevance, this study provides the first detection and characterization of LCMV in Brazil. We analyzed 236 rodent serum samples and 78 tissue samples from synanthropic rodents (Mus musculus, Rattus rattus, and Rattus norvegicus) collected during seven independent expeditions across the state of Rio de Janeiro, Southeastern Brazil. Using ELISAs, IgG anti-LCMV antibodies were detected in 20% of rodents, including two R. rattus (2/10), two R. norvegicus (2/95), and forty-five M. musculus (45/131). The LCMV’s RNA was amplified and partially sequenced from fourteen M. musculus, and complete S segment sequences were obtained from two mouse samples. Phylogenetic analyses revealed that these Brazilian strains belong to lineage I, which is composed of strains that induce disease in humans. Our results underscore the importance of implementing integrated surveillance for this zoonosis in Brazil.
Screening out microRNAs and Their Molecular Pathways with a Potential Role in the Regulation of Parvovirus B19 Infection Through In Silico Analysis Vívian de Almeida Salvado, Arthur Daniel Rocha Alves, Wagner Luis da Costa Nunes Pimentel Coelho, Mayla Abrahim Costa, Alexandro Guterres, Luciane Almeida Amado International Journal of Molecular Sciences, 2025 Parvovirus B19 (B19V) infection in healthy individuals is commonly asymptomatic or has non-specific symptoms, such as fever, headache, chills, myalgia, rash, and arthralgia. However, some groups of individuals, such as pregnant women, patients with hemolytic disorders, and immunocompromised individuals, may present severe forms of the infection, which may even lead to a negative outcome. To better understand what leads to this divergence of outcomes in different populational groups, this study sought to analyze the role of miRNAs in the pathogenesis of B19V infection. The miRNAs that potentially bind to the B19V transcripts were identified using complete genomic sequences retrieved from Genbank and miRNAs cataloged in miRbase. The results of this alignment between the seed region of the miRNAs with the B19V complete genome identified 1517 miRNAs that showed 100% identity, of which 412 are bound to NS1, VP1, and VP2 transcripts. Based on the number of total binds to the genome, these miRNAs were ranked, and the top five, miR-4799-5p, miR-5690, miR-335-3p, miR-193b-5p, and miR-6771-3p, were selected to evaluate the target genes and signaling pathways in which they act. We identified 214 common genes among the top five miRNAs, and five of these genes bind to at least two of these miRNAs. Based on WikiPathways and KEGG, these 214 genes act on 29 statistically significant pathways, and the three main pathways were selected. Our results revealed some miRNAs that may be involved in regulating B19V replication and that can act as potential biomarkers for the prognosis of infection.
Using digital PCR to investigate the prevalence of KRAS variants in pituitary tumours Veronica Aran, Elisa Lamback, Renan Lyra Miranda, Alexandro Guterres, Isabel Souza Barbosa, Leila Chimelli, Mônica Roberto Gadelha, Vivaldo Moura Neto Journal of Neuroendocrinology, 2025 Pituitary tumours (PT) are formed in the pituitary gland, a small gland situated at the base of the brain. These tumours can be categorized according to their histological origin and hormone production. In surgical series, non‐functioning PT are the commonest subtype, followed by functioning somatotroph and corticotroph tumours. Different somatic alterations have been implicated in the pathogenesis of these tumours and the objective of our study was to expand our previous new finding of KRAS pathogenic genetic variants in pituitary tumours. We conducted a digital polymerase chain reaction (PCR) analysis on formalin‐fixed paraffin‐embedded tissue blocks belonging to 189 patients. The results showed that, from the 184 pituitary tumours with good quality samples, 13 tumours (7.1%) presented mutant KRAS. The median age of the mutated group was 47 years old (range 19–77) and most patients with mutant KRAS tumours were from the female gender (61.5%, 8/13) and non‐functioning subtype. For the first‐time, mutant KRAS in corticotroph and somatotroph tumours were detected, and the variants showed low allele frequencies. In conclusion, we demonstrated that pituitary tumours might have mutant KRAS, and these data were not previously described probably due to lack of sensitivity of previous technologies. By identifying these variants, even at minimal levels, we open doors to a deeper understanding of the tumour microenvironment, clonal evolution and potential therapeutic targets.
Breaking Barriers: A Future Perspective on Glioblastoma Therapy with mRNA-Based Immunotherapies and Oncolytic Viruses Alexandro Guterres, Paulo Niemeyer Soares Filho, Vivaldo Moura-Neto Vaccines, 2024 The use of mRNA-based immunotherapies that leverage the genomes of oncolytic viruses holds significant promise in addressing glioblastoma (GBM), an exceptionally aggressive neurological tumor. We explore the significance of mRNA-based platforms in the area of immunotherapy, introducing an innovative approach to mitigate the risks associated with the use of live viruses in cancer treatment. The ability to customize oncolytic virus genome sequences enables researchers to precisely target specific cancer cells, either through viral genome segments containing structural proteins or through a combination of regions with oncolytic potential. This strategy may enhance treatment effectiveness while minimizing unintended impacts on non-cancerous cells. A notable case highlighted here pertains to advanced findings regarding the application of the Zika virus (ZIKV) in GBM treatment. ZIKV, a member of the family Flaviviridae, shows oncolytic properties against GBM, opening novel therapeutic avenues. We explore intensive investigations of glioblastoma stem cells, recognized as key drivers in GBM initiation, progression, and resistance to therapy. However, a comprehensive elucidation of ZIKV’s underlying mechanisms is imperative to pave the way for ZIKV-based clinical trials targeting GBM patients. This investigation into harnessing the potential of oncolytic-virus genomes for mRNA-based immunotherapies underscores its noteworthy implications, potentially paving the way for a paradigm shift in cancer treatment strategies.
The role of immune subtyping in glioma mRNA vaccine development Alexandro Guterres, Mayla Abrahim, Patrícia Cristina da Costa Neves Immunotherapy, 2023 Studies on the development of mRNA vaccines for central nervous system tumors have used gene expression profiles, clinical data and RNA sequencing from sources such as The Cancer Genome Atlas and Chinese Glioma Genome Atlas to identify effective antigens. These studies revealed several immune subtypes of glioma, each one linked to unique prognoses and genetic/immune-modulatory changes. Potential antigens include ARPC1B, BRCA2, COL6A1, ITGB3, IDH1, LILRB2, TP53 and KDR, among others. Patients with immune-active and immune-suppressive phenotypes were found to respond better to mRNA vaccines. While these findings indicate the potential of mRNA vaccines in cancer therapy, further research is required to optimize administration and adjuvant selection, and precisely identify target antigens.
