Recently, reports of hemoplasmas in Brazilian wildlife have increased exponentially, reflecting advances in molecular diagnosis, bioinformatic analyses, and broader access to these tools. The present scoping review updates the current available information on hemoplasmas occurrence and genetic diversity in Brazilian wildlife, including terrestrial, aquatic, and flying mammals, as well as exotic species. The review included 59 scientific papers published between 2007 and 2025. Most records are concentrated in the Atlantic Forest and Pantanal biomes, with rodents showing the highest genetic diversity, potentially reflected by a larger number of analyzed samples. Some mammal groups harbor apparently host-specific hemoplasmas lineages, such as tapirs (Tapirus terrestris), opossums (Didelphis spp.), crab-eating raccoons (Procyon cancrivorus), and neotropical otters (Lontra longicaudis). Collectively, available data demonstrate that hemoplasmas are widespread and frequently reported in Brazilian wildlife. Although the use of multi-locus sequencing and comprehensive phylogenetic reconstructions have provided additional insights when compared to single-gene analyses, their resolution is still limited for clarifying the evolutionary relationships and taxonomic placement of hemoplasmas. Looking ahead, advances in genomic comparisons may further deepen our understanding of hemoplasmas diversity and evolution.","PeriodicalId":48990,"journal":{"name":"Revista Brasileira De Parasitologia Veterinaria","volume":"35 1","pages":"e017725"},"PeriodicalIF":1.2,"publicationDate":"2026-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13193329/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147949981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collections were carried out between September 2023 and March 2024 at ten sampling points distributed across residential (RZ) and agricultural (AZ) zones. A total of 220 phlebotomine sand flies were captured, belonging to six genera and eleven species. The most abundant species was Evandromyia lenti. Three species of recognized epidemiological importance were identified: Lu. cruzi, Lu. longipalpis and Nyssomyia whitmani, with the latter recorded for the first time in Várzea Grande municipality. The results indicate low diversity and evenness in both sampled environments, with greater community balance in the AZ and higher dominance in the RZ. These findings suggest low diversity, high dominance, and potential ecological imbalance, particularly in areas with a higher degree of anthropogenic disturbance.

Entomopathogenic fungi (EPF) have gained significant prominence as biological alternatives for integrated tick management. This review synthesizes over two decades of advances in fungal-based tick control, including recent field trials, formulation technologies, and omics-driven mechanistic insights. Evidence shows that species within the genera Metarhizium and Beauveria exhibit consistent pathogenicity against several ixodid ticks, although efficacy varies with fungal isolate, propagule type, formulation, and environmental conditions. Advances in omics approaches have improved understanding of infection mechanisms and tick immune responses, while formulation and delivery innovations have enhanced fungal stability and field persistence. Field studies demonstrate variable but promising efficacy, particularly when EPF are applied within integrated control strategies. However, important challenges remain, including limited large-scale field validation and optimization of formulations. By integrating laboratory, field, and commercial evidence across production systems, this review identifies key technological bottlenecks and highlights future directions for climate-resilient and sustainable tick control.","PeriodicalId":48990,"journal":{"name":"Revista Brasileira De Parasitologia Veterinaria","volume":"35 1","pages":"e019725"},"PeriodicalIF":1.2,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13142159/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147786588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In A. montensis, young individuals presented a greater abundance than did adults.

In this study, the prevalence of CVL and its associated socio-environmental factors were investigated. A cross-sectional study was conducted involving 243 dogs residing in both urban and rural areas. Blood samples were analyzed using the rKDDR-plus immunochromatographic test, conventional polymerase chain reaction (cPCR), and quantitative real time polymerase chain reaction (qPCR). In addition, household questionnaires were administered to assess socio-environmental conditions. Based on the rKDDR-plus serology, four samples tested positive (1.6%), and qPCR confirmed the presence of Leishmania infantum DNA in three samples (1.2%). Among the environmental factors analyzed, improper waste management (38.3%) and proximity of households to vegetation (54.7%) were notable. The detection of seropositive samples and L. infantum DNA suggests the existence of a transmission cycle of canine visceral leishmaniasis (CVL) in the studied area.

We aimed to characterize Hepatozoon species infecting the blood and spleen of amphibians and reptiles in Mato Grosso, Midwestern Brazil, using morphological and molecular tools. In total, 146 animals from 19 species (8 amphibians and 11 reptiles) were evaluated. Giemsa-stained blood smears revealed Hepatozoon-like inclusions in 35 individuals (8 amphibians and 27 reptiles), including new infection records in the anurans Boana raniceps and Trachycephalus typhonius, and the snake Eunectes notaeus. Morphological analysis revealed diverse morphotypes. Molecular analysis of the 18S rRNA gene identified six haplotypes in Rhinella diptycha, Ameiva ameiva, Boa constrictor, Epicrates crassus, E. notaeus, and Caiman yacare. Phylogenetic analyses revealed clustering with clades linked to H. musa and H. caimani, suggesting the presence of potentially novel lineages. These findings highlight the high genetic diversity of Hepatozoon in the region and emphasize the value of integrative approaches in parasitological research.","PeriodicalId":48990,"journal":{"name":"Revista Brasileira De Parasitologia Veterinaria","volume":"34 4","pages":"e012125"},"PeriodicalIF":1.2,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12974785/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146120447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
