Gallium maltolate, a promising low toxicity drug with curative effect on mice chronically infected with Trypanosoma evansi.

Trypanosoma evansi is a flagellate protozoan that infects a wide range of hosts, especially horses. Clinically, the infection is characterized by rapid weight loss, anemia and mobility disorders. This study evaluated the efficacy of treatment gallium maltolate (GaM) in rats infected with T.

Antagonistic Interplay between MicroRNA-155 and IL-10 during Lyme Carditis and Arthritis.

MicroRNA-155 has been shown to play a role in immune activation and inflammation, and is suppressed by IL-10, an important anti-inflammatory cytokine. The established involvement of IL-10 in the murine model of Borrelia burgdorferi-induced Lyme arthritis and carditis allowed us to assess the interplay between IL-10 and miR-155 in vivo. As reported previously, Mir155 was highly upregulated in joints from infected severely arthritic B6 Il10-/- mice, but not in mildly arthritic B6 mice.

Dose finding of 3'deoxyadenosine and deoxycoformycin for the treatment of Trypanosoma evansi infection: An effective and nontoxic dose.

The aim of this study was to evaluate the therapeutic efficacy and safety of using 3'deoxyadenosine (Cordycepin - adenosine analogue) combined with deoxycoformycin (Pentostatin - an adenosine deaminase inhibitor) in mice infected with Trypanosoma evansi. We show that the combination of Cordycepin (2.0 mg kg(-1)) and Pentostatin (0.

Diminazene aceturate liposomes: morphometric and biochemical liver, kidney, and spleen of rats infected with Trypanosoma evansi.

The aim of this study was to evaluate the effect of treatment with liposomal (L-DMZ) and conventional (C-DMZ) diminazene aceturate formulations on hepatic and renal functions of rats, experimentally infected with Trypanosoma evansi. For this purpose, 72 Wistar rats (Rattus norvegicus) were divided into six groups (A, B, C, D, E, and F). Each group was subdivided into two other subgroups in order to assess the biochemical and histological results on days 7 and 40 post-treatment (PT).

Liposomes produced by reverse phase evaporation: in vitro and in vivo efficacy of diminazene aceturate against Trypanosoma evansi.

This study aimed to develop and test the in vitro and in vivo effectiveness of diminazene aceturate encapsulated into liposomes (L-DMZ) on Trypanosoma evansi. To validate the in vitro tests with L-DMZ, the efficacy of a commercial formulation of diminazene aceturate (C-DMZ) was also assessed. The tests were carried out in culture medium for T.

Influence of treatment with 3'-deoxyadenosine associated deoxycoformycin on hematological parameters and activity of adenosine deaminase in infected mice with Trypanosoma evansi.

This study aimed to verify the effect of 3'-deoxyadenosine and deoxycoformycin on hematologic parameters and adenosine deaminase (ADA) activity in plasma and brain of mice infected with Trypanosoma evansi. Seventy animals were divided into seven groups, which were divided into two subgroups each for sampling on days 4 and 8 post-infection (PI). The groups were composed of three uninfected groups (A-C), namely, not-treated (A), treated with 3'-deoxyadenosine (B), and treated with deoxycoformycin (C) and four infected groups, mice with T.

Case report: Feline infection by Lagochilascaris sp. in the State of Rio Grande do Sul, Brazil.

Lagochilascariosis is a zoonotic disease caused by the nematode Lagochilascaris sp., with the northern of Brazil representing 81.2% of all reports of the disease worldwide.

Cordycepin (3'-deoxyadenosine) pentostatin (deoxycoformycin) combination treatment of mice experimentally infected with Trypanosoma evansi.

The aim of this study was to evaluate the anti-trypanosomal effect of treatment with 3'-deoxyadenosine (cordycepin) combined with deoxycoformycin (pentostatin: inhibitor of the enzyme adenosine deaminase) in vitro by using mice experimentally infected with Trypanosoma evansi. In vitro, a dose-dependent trypanocidal effect of cordycepin was observed against the parasite. In the in vivo trials, the two drugs were used individually and in combination of different doses.

Trypanosoma evansi: effects of zinc and copper in experimentally infected rats.

The aim of this study was to evaluate the effects of a treatment using injectable zinc and copper in rats infected with Trypanosoma evansi. 48 rats were divided into eight groups of six animals each. Group A was composed of uninfected animals.

Susceptibility of Trypanosoma evansi to propolis extract in vitro and in experimentally infected rats.

Current therapy of Trypanosoma evansi infections is not effective for the vast majority of animals with relapsing parasitemia and clinical signs. Recently, attention is being focused on the antiparasitic activity of propolis. This study evaluated the susceptibility of T.

Toxoplasma gondii antibodies on domiciled cats from Lages municipality, Santa Catarina State, Brazil.

Sera were collected from 300 domiciled cats from the municipality of Lages, Southern Brazil, to determine the prevalence of Toxoplasma gondii antibodies and risk factors associated. Tests for T. gondii antibodies were performed using indirect immunofluorescent antibody test (IFAT).

[Ectoparasites and intestinal helminths in Felis catus domesticus from Lages city, SC, Brazil and social-economical and cultural aspects of owners of family pets].

The purpose of this research was to determinate the prevalence of ectoparasites and gastrointestinal (GI) parasites in domiciliated cats, from central and peripheral region, of Lages city, Santa Catarina State and also characterize the economic, social and cultural status of families' pet owners. From the period of December 2005 to December 2006, 600 questionnaires were distributed to pet owners of Lages city and ectoparasites and faeces were collected. The prevalence of ectoparasites was 13.
