The objective of this study was to develop a quantitative 5' nuclease real-time polymerase chain reaction (PCR) assay diagnose infections caused by Bartonella species.
The occurrence of Trypanosoma spp. in wild carnivore populations has been intensively investigated during the last decades. However, impact these parasites on health free-living infected animals largely neglected. Pantanal biome is world's largest seasonal wetland, harboring a great diversity species and habitats. This includes 174 mammals, which 20 belong to order Carnivora. present study aimed investigate effect evansi cruzi infections coinfections most abundant carnivores Pantanal: coati...
Domestic dogs are considered reservoirs hosts for several vector-borne parasites. This study aimed to evaluate the role of domestic as Trypanosoma cruzi, evansi and Leishmania spp. in single co-infections Urucum settlement, near Brazil-Bolivian border. Additionally, we evaluated involvement wild mammals' maintenance these parasites area. Blood samples (n = 62) six species mammals 36) were collected July August 2015. The infections assessed using parasitological, serological molecular tests....
Introduction Trypanosomatids are parasites widely distributed in nature, parasitizing several host species single or co-infections. Campo Grande (CG), capital of Mato Grosso do Sul State, is characterized by green areas and forest fragments where wild mammals have been reported infected diverse trypanosomatid species. In this study, we evaluated the parasitism trypanosomatids non-human primates (NHP) Sapajus cay Alouatta caraya sampled three different CG. Material methods For detection...
Globally, hemotropic mycoplasmas (hemoplasmas) comprise an emerging or remerging bacteria group that attaches to red blood cells of several mammal's species and in some cases, causing hemolytic anemia. Herein, we assessed the occurrence, genetic diversity, factors coupled mammals infection, phylogeographic distribution hemoplasmas sylvatic synanthropic their associated ectoparasites from Brazil. We collected spleen and/or samples rodents (Rattus rattus [N = 39] Mus musculus 9]),...
Distinct species of Trypanosoma have been documented sharing the same hosts in different environments intricate transmission networks. Knowing this, this study investigated role cycles Pantanal biome. The mammals were sampled from November 2015 to October 2016. We a total 272 wild 27 belonging six orders and 15 families, three triatomines (n = 7). found high parasitemias by Hemoculture test for cruzi (TcI), rangeli, marinkellei dionisii, Microhematocrit Centrifuge Technique evansi. carnivore...
Different parasites that commonly occur concomitantly can influence one another, sometimes with unpredictable effects. We evaluated pathological aspects of dogs naturally co-infected Leishmania infantum and Ehrlichia canis. The health status the was investigated based on histopathological, hematological biochemical analyses 21 animals infected solely L. 22 co- E. skin both groups showed chronic, predominantly lymphohistioplasmacytic inflammatory reaction. plasmacytosis in lymphoid tissues...
The Anaplasmataceae family encompasses obligate intracellular α-proteobacteria of human and veterinary medicine importance. This study performed multi-locus sequencing to characterize Ehrlichia Anaplasma in coati's blood samples Midwestern Brazil. Twenty-five (25/165-15.1%) were positive the screening PCR based on dsb gene spp. characterized using 16S rRNA, sodB, groEL, gltA genes 23S-5S intergenic space region (ITS). Phylogenetic analyses all six molecular markers positioned sequences into...
Worldwide, Bartonella species are known to infect a wide range of mammalian and arthropod hosts, including humans. The current study aimed investigate the prevalence spp. in synanthropic mammals captured peri-urban areas from Central-Western Southern Brazil their ectoparasites. For this aim, 160 belonging four species, 218 associated arthropods were sampled. DNA was extracted subjected different screening assays. Additionally, blood samples 48 small rodents submitted liquid BAPGM culture...
Zika virus (ZIKV) was first discovered in 1947 Uganda but not considered a public health threat until 2007 when it found to be the source of epidemic activity Asia. Epidemic spread Brazil 2014 and continued throughout tropical subtropical regions Americas. Despite ZIKV being zoonotic origin, information about transmission, or even exposure non-human vertebrates mosquitoes Americas, is lacking. Accordingly, from February 2017 March 2018, we sought evidence sylvatic transmission by sampling...
Understanding the diversity and ecology of ectoparasites in wild animals is essential for surveillance vector-borne diseases. Coatis (Nasua nasua) easily adapt to anthropized areas, favoring close contact with domestic humans, possibility exchange pathogens. The present study aimed identify ticks parasitizing coatis from forest urban areas midwestern Brazil, evaluate seasonal dynamics during seasons year, assess correlation between tick species gender age sampled coatis. For this purpose,...
Considered ecologically generalist, Didelphis albiventris is reported as reservoir for different species of parasites, especially Trypanosoma cruzi. However, the knowledge about influence T. cruzi on hematological parameters free-living opossum remains scarce. The present study aimed to evaluate white-ear opossums (D. albiventris) from Campo Grande, Mato Grosso do Sul, Brazil. blood samples and biometric data were collected 40 captured by Tomahawk Sherman traps in six urban forest fragments...
Abstract The msp4 gene of A. marginale is unicodon, stable and mostly homogeneous, being considered as a useful marker for phylogeographic characterization this bacterium. objective work was to analyze the phylogeography based on in beef cattle from Brazilian Pantanal, compared those found other regions worldwide. blood samples investigated were collected 400 animals (200 cows 200 calves) reared five extensive breeding farms region. results indicated that evaluated samples, 56.75% (227/400)...
Although primarily arboreal, the capuchin monkey ( Sapajus cay ) descends to ground for several reasons. We used terrestrial records obtained by camera-trapping surveys investigate seasonality in terrestriality of monkeys, reasons descend ground, and periods day when was more pronounced. carried out study Urucum Massif, Brazilian Pantanal. data from 2 dry rainy seasons. Terrestrial behaviours were categorized, activity patterns described using a kernel density approach. observed seasonal...
