Molecular identification of Giardia duodenalis isolates from humans, dogs, cats and cattle from the state of São Paulo, Brazil, by sequence analysis of fragments of glutamate dehydrogenase (gdh)
The nucleotide sequence of glutamate dehydrogenase (gdh) coding genes were obtained from cysts of Giardia duodenalis isolated from feces of naturally infected cats (n=19), dogs (n=27), humans (n=37)Expand

Toxoplasma gondii infection in cats from São Paulo state, Brazil: seroprevalence, oocyst shedding, isolation in mice, and biologic and molecular characterization.
Cats are the most important hosts in the epidemiology of Toxoplasma gondii infections in humans and animals. Serologic and parasitological prevalence of T. gondii were determined in 237 cats from 15Expand

Genetic diversity among capybara (Hydrochaeris hydrochaeris) isolates of Toxoplasma gondii from Brazil.
Recent studies indicate that Toxoplasma gondii isolates of many domestic hosts from Brazil are genetically and biologically different from T. gondii isolates from USA and Europe. However, little isExpand

Diagnosis of Canine Brucellosis: Comparison between Serological and Microbiological Tests and a PCR Based on Primers to 16S-23S rDNA Interspacer
A pair of primers directed to 16S-23S rDNA interspacer (ITS) was designed directed to Brucella genetic sequences in order to develop a polymerase chain reaction (PCR) putatively capable of amplifyingExpand
