Abstract Background Chagas disease (CD) is a neglected zoonosis that requires study through the One Health approach, as it involves various aspects of animal, environmental, and human health in its transmission cycle. This affects 7 million people 20 countries Latin America, resulting approximately seven thousand deaths annually worldwide. Local knowledge crucial for developing educational strategies to mitigate risks transmission, particularly endemic areas. Aims In this study, we present...
The Bartonella species are zoonotic agents that infect mammals and transmitted by arthropod vectors. Approximately 18 distinct genotypes cause diseases in humans, may be spread both domestic wild animals. In Brazil, have been identified several of mammals, the present study, we analyzed samples from non-human primates (marmosets), marsupials, rodents, bats, compared them with described to examine distribution two impacted areas Rio de Janeiro state, southeastern Brazil. We used polymerase...
Chagas Disease (CD) affects 6-7 million people worldwide and is related to poverty-promoting conditions. Chronic asymptomatic cases are mostly invisible health systems. Aiming (1) translate CD discoveries into education/information practices raise alertness empowerment of affected people; (2) perform an active search cases, articulating intersectoral actions improve the access infected local service for treatment CD; our research group developed tested under field conditions as innovative...
Abstract The Hyphomicrobiales bacterial order (previously Rhizobiales) exhibits a wide range of lifestyle characteristics, including free-living, plant-association, nitrogen-fixing, and association with animals ( Bartonella Brucella ). This study explores the diversity evolutionary strategies bacteriophages within order, comparing animal-associated (AAB) non-animal-associated bacteria (NAAB). We curated 560 high-quality complete genomes 58 genera from this used PHASTER server for prophage...
Rodents and bats are the most diverse mammal group that host Bartonella species. In Americas, they were described as harboring species; however, mostly characterized to genotypic level. We describe here isolates obtained from blood samples of one rodent (Peromyscus yucatanicus San José Pibtuch, Yucatan) two bat species (Desmodus rotundus Progreso, Pteronotus parnellii Chamela-Cuitzmala) Mexico. sequenced genomic features three strains performed phylogenomic pangenome analyses decipher their...
Small mammals (marsupials and rodents) are one of the most diverse groups Atlantic Forest mammals, representing 40% total diversity in this biome. Some regions, such as northwestern Rio de Janeiro state, have gaps mammal inventories. Therefore, we performed small inventories four fragmented landscapes state using live traps camera traps. Capture transects were placed both forest fragments altered matrix. We captured six species marsupials, Sigmodontinae rodents echimyid rodent. The fauna...
Ticks (Acari: Ixodidae) collected from wild birds in Panama were tested for the presence of tick-borne pathogens as Rickettsia, Anaplasma, Ehrlichia, Bartonella, Borrelia, Hepatozoon sp., and Babesia. Overall 124 ticks found 57 belonging to 28 species: Amblyomma longirostre (32 larvae, 1 nymph), nodosum (30 nymphs), geayi (15 varium (5 2 naponense (2 larvae), ovale calcaratum (1 larva). DNA Rickettsia amblyommatis was detected 65% A. longirostre, 69% 14% varium. Moreover, results two larvae...
Abstract Background Blood culture-negative infective endocarditis is a potentially severe disease that can be associated with infectious agents such as Bartonella spp., Coxiella burnetti , Tropheryma whipplei and some fungi. Case presentation Reported here are two cases of blood in patients aortic mitral regurgitation Brazil; the first case 47-year-old white man second 62-year-old woman. henselae deoxyribonucleic acid was detectable samples cardiac valve vegetation paraffin-fixed tissue...
Toxoplasmosis is an important zoonotic disease caused by the parasite Toxoplasma gondii and especially fatal for neotropical primates. In Brazil, Ministry of Health responsible national epizootic surveillance, but some diseases are still neglected. Here, we present integrated investigation outbreak that occurred during first year COVID-19 pandemic among eleven primates housed at a primatology center in Brazil. After presenting non-specific clinical signs, all animals died within four days. A...
The differential diagnosis of optic neuritis is broad and varied. We report the case a 24-year-old Brazilian man who presented with five-week history fever, malaise, myalgia, severe fatigue, tender right preauricular lymphadenopathy, acute vision blurring associated disc swelling exudates in macular star pattern. His illness developed soon after an infestation fleas broke out among his cats. Diagnosis ocular bartonellosis was confirmed by serological molecular analyses targeting...
Abstract Background Phylogeny, combined with trait-based measures, offers insights into parasite sharing among hosts. However, the specific traits that mediate transmission and aspects of host community diversity most effectively explain infection rates remain unclear, even for Bartonella genus, a vector-borne bacteria causes persistent blood infections in vertebrates. Methods This study investigated association between rodent infection, as well how affects odds Atlantic Forest, using...
Background: Despite advances in diagnosis and treatment, the incidence mortality of infective endocarditis (IE) have increased recent decades despite treatment. Studies on risk factors for Latin America are scarce. Methods: This retrospective cohort study included 240 patients diagnosed with IE according to modified Duke criteria who were admitted two university hospitals Rio de Janeiro, Brazil from January 2009 June 2021. Poisson regression analysis was performed trend tests. The...

Since 1984, the Laboratory of Biology and Parasitology Reservoir Wild Mammals (LABPMR) has been establishing a scientific collection, intending to carry out studies on taxonomy, biogeography, ecology mammals in Brazil, aiming understand their role zoonotic agents transmission cycles. In this context, LABPMR also acts as reference laboratory for Ministry Health, providing taxonomic reports species involved cycles, based integrative taxonomy (morphological/morphometric, karyotypic, molecular...
We wish to report the occurrence of adult nematodes Ophidascaris arndti (Ascarididae) naturally infecting a new definitive host, Fonseca's lancehead Bothrops fonsecai (Viperidae), and third-stage larvae O. parasitizing intermediate montane grass mouse Akodon montensis (Cricetidae), both found in Atlantic Forest state Rio de Janeiro, Brazil. elucidated morphological characteristics adults using light scanning electron microscopy (SEM). Taxonomic affinities between worms were assessed MT-CO1...
Abstract As exemplified by the Coronavirus Disease 2019 (COVID-19) pandemic, infectious diseases may emerge and spread rapidly, often causing serious economic losses public health concerns. In fact, disease outbreaks have become increasingly common, especially those of zoonotic origin. The Brazilian Ministry Health is responsible for national epizootic surveillance. However, system’s focus primarily on affecting humans has led to neglect other diseases. this report, we present an integrated...
Abstract Fecal starch analysis is a useful tool for monitoring digestibility in beef feeding operations. The aim of this study was to investigate the effects time day and feces storage method on fecal concentration. A commercial feedlot asked participate study. For both experiments, samples were collected from 5 pens (replicates) cattle, which consuming finishing diet about 40 d. Dry-ground corn primary energy source, with an inclusion 32.6% DM diet. Corn silage another source (15.5% diet)....
