Evaluation of Toxoplasma gondii and Neospora caninum infections in sheep from Uberlândia, Minas Gerais State, Brazil, by different serological methods.
TLDR
It is emphasized the importance to carry out a regular monitoring of Toxoplasma infection due to its high prevalence, its zoonotic potential and induction of reproductive disorders leading to economic losses. Expand
Attachment of Toxoplasma gondii to host cells involves major surface protein, SAG-1 (P30).
TLDR
Observations suggest that SAG-1 is an important parasite ligand that binds to the host cell in the process of T. gondii invasion. Expand
Detection of Immunoglobulin G Antibodies to Neospora caninum in Humans: High Seropositivity Rates in Patients Who Are Infected by Human Immunodeficiency Virus or Have Neurological Disorders
TLDR
The results of this study indicate the presence of N. caninum infection or exposure in humans, particularly in HIV-infected patients or patients with neurological disorders, who could have opportunistic and concurrent infections with T. gondii. Expand
Evaluation of serological tests for the diagnosis of Neospora caninum infection in dogs: optimization of cut off titers and inhibition studies of cross-reactivity with Toxoplasma gondii.
TLDR
The results indicate that ELISA should be used critically when crude tachyzoite antigen preparations are employed, due to possible cross-reactivity with other related parasites as T. gondii. Expand
Toxoplasma gondii micronemal protein MIC1 is a lactose-binding lectin.
TLDR
It is demonstrated here that micronemal protein 1 (MIC1) is a lactose-binding lectin, which suggests that MIC1 may act through its lectin activity during T. gondii infection. Expand
Toxoplasma gondii: effects of Artemisia annua L. on susceptibility to infection in experimental models in vitro and in vivo.
TLDR
The results indicate that A. annua infusion is useful to control T. gondii infection, due to its low toxicity and its inhibitory action directly against the parasite, resulting in a well tolerated therapeutic tool. Expand
Attachment of Toxoplasma gondii to host cells is host cell cycle dependent
TLDR
Findings suggest that Toxoplasma tachyzoites bind specifically to a host cell receptor which is upregulated in the mid-S phase of the cell cycle, which is critical in the pathogenesis of this infection. Expand
Use of SAG2A recombinant Toxoplasma gondii surface antigen as a diagnostic marker for human acute toxoplasmosis: analysis of titers and avidity of IgG and IgG1 antibodies.
TLDR
SAG2A is an antigen that may be used as a diagnostic tool to characterize the acute phase Toxoplasma gondii infection and the epitope recognized by A4D12 mAb may be critical for the recognition of this molecule. Expand
Detection of IgG antibodies to Neospora caninum and Toxoplasma gondii in dogs examined in a veterinary hospital from Brazil.
TLDR
The results suggest that the infection by N. caninum can be concomitantly present in dogs from this area, although less common, and therefore should be considered in the differential clinical diagnosis with T. gondii in dogs presenting neuromuscular, respiratory and/or gastrointestinal disorders. Expand
Toxoplasmosis in Naturally Infected Deer from Brazil
TLDR
Senim samples from 107 cervids were examined for Toxoplasma gondii antibodies using indirect hemagglutination (IHA), indirect immunofluorescence (IFA), enzyme linked immunosorbent assay (ELISA) and Dot-ELISA and the convenience of the Dot- ELISA test is obvious. Expand
