Introduction
I am a veterinarian affiliated to the Smithsonian’s National Zoo and Conservation Biology Institute and to the Center for Vector Biology at Rutgers University. I am interested in wildlife diseases, especially those transmitted by Diptera and tick vectors. I have field and laboratory experience with pathogens that infect birds, lizards, rodents, carnivores, primates and bats.

Espinilho savanna (“seasonal steppe savanna”) is a unique vegetation formation of the Pampas biome that is found near the tri-border of Brazil, Uruguay, and Argentina. The Yellow Cardinal (Gubernatrix cristata) is a flagship species of this ecosystem, but it is classified as “critically endangered” in Brazil due to habitat loss and poaching for the...

Background Plasmodium parasites that cause bird malaria occur in all continents except Antarctica and are primarily transmitted by mosquitoes in the genus Culex . Culex quinquefasciatus , the mosquito vector of avian malaria in Hawaiʻi, became established in the islands in the 1820s. While the deadly effects of malaria on endemic bird species have...

Great-tailed Grackles ( Quiscalus mexicanus ) are a social, polygamous bird species whose populations have rapidly expanded their geographic range across North America over the past century. Before 1865, Great-tailed Grackles were only documented in Central America, Mexico, and southern Texas in the USA. Given the rapid northern expansion of this s...

Culex quinquefasciatus , the mosquito vector of avian malaria in Hawaiʻi, became established in the islands in the 1820s and the deadly effects of malaria on endemic bird species have been documented for many decades. To evaluate the gene expression response of the mosquito to the parasite, we let the offspring of wild-collected Hawaiian Cx. quinqu...

This study aimed to determine the occurrence of Leishmania infection in bats in urban and wild areas in an endemic municipality for visceral and cutaneous leishmaniasis in Minas Gerais, Brazil. Between April 2014 to April 2015, 247 bats were captured and classified into 26 species belonging to Phyllostomidae (90.7%), Vespertilionidae (8.1%) and Mol...
Article
Avian Haemosporidian parasites - Plasmodium, Haemoproteus, Leucocytozoon and Fallisia - have a wide distribution except for Antarctica. Leucocytozoon sp. has been poorly described in Brazil, and few studies have indicated infections in birds from the Atlantic Forest, Pantanal, Pampa and Amazon biomes. This study describes, for the first time, the o...
Article
Full-text available
Aim: Macroecological analyses provide valuable insights into factors that influence how parasites are distributed across space and among hosts. Amid large uncertainties that arise when generalizing from local and regional findings, hierarchical approaches applied to global datasets are required to determine whether drivers of parasite infection pat...

Article
Delimiting and describing Plasmodium species in reptiles remains a pressing problem in Haemosporida taxonomy. The few morphological characters used can overlap, and the significance of some life-history traits is not fully understood. Morphologically identical lizard Plasmodium forms have been reported infecting different cell types (red and white...

Vector-host interactions play a central role in the transmission of vector-borne diseases. Determining the factors that affect vector attraction to vertebrate hosts is critical to understand disease ecological dynamics. Using malaria as the primary model, we reviewed studies that examined whether pathogen infection and host traits affect mosquito a...
Article
Human induced changes on landscape can alter the biotic and abiotic factors that influence the transmission of vector-borne parasites. To examine how infection rates of vector-transmitted parasites respond to changes on natural landscapes, we captured 330 Blue-black Grassquits (Volatinia jacarina) in Brazilian biomes and assessed the prevalence and...
Chapter
Haemosporidian parasites are a globally distributed group of protists that infects many species of vertebrates (amphibians, reptiles, birds, and mammals) and are transmitted by bloodsucking dipteran insects (Insecta: Diptera). Although significant progress has been made toward understanding the details of the life cycle of these parasites, our curr...

An infestation of cat fleas in a research center led to the detection of two genotypes of Ctenocephalides felis biting humans in New Jersey, USA. The rarer flea genotype had an 83% incidence of Rickettsia asembonensis, a recently described bacterium closely related to R. felis, a known human pathogen. A metagenomics analysis developed in under a we...

Question
Are they reliable and durable enough? I am thinking of buying one machine, so I would appreciate any sugestions of brands with prices similar to Prime's that are even better rated. 
Thanks for any help :)
Cheers!
Question
Does anyone know if a pair of primers designed to use with fluorescent probes (using TaqMan system) could be used in a system that do not use probes (like EvaGreen), obtaining the same results?
Question
I have a MJ research PT-100 thermo cycler that's not working. The electrician told me that a need to replace the peltier cell. He calculated the the peltier I need would need to have about 112w. I'm having problems to find a proper cell. Has anyone delt with such a problem that could give some help?

We are interested in possible effects that different land use types have on parasite prevalence and diversity. For that, we use haemosporidian parasites (Plasmodium and Haemoproteus) that infect birds and are transmitted by a huge diversity of dipterans. For one part of our project, we investigated parasite distribution in birds and in mosquitoes sampled across areas on different ecological succession stages. We also sampled birds in the transition area between a National Park and small farms in the Cerrado biome. Surprisingly, we found that an avian malaria parasite common in backyard chickens infected passerines captured close to those farms. In a third section of this project, we tested black-fronted piping-guans born in captivity and that were going to be reintroduced into the wild. Half of the birds harbored a parasite that we described as a new species of Haemoproteus, a parasite group transmitted by biting midges (Ceratopogonidae family).
