A 20-year serological survey of Toxoplasma gondii and Neospora caninum infection in dogs with neuromuscular disorders from urban areas in Argentina.

Toxoplasma gondii and Neospora caninum infections may be associated with neuromuscular disorders in dogs. The aim of this study was to assess the seroprevalence to these protozoan parasites in dogs with neuromuscular disease from urban areas of Buenos Aires province, Argentina, over a period of 20 years, and to evaluate the association of seropositivity and antibody titres with different variables such as sex, breed and age. For this, a total of 7238 serum samples from urban owned dogs were analysed by the indirect fluorescence antibody test (IFAT) for specific IgG antibodies.

Study of specific immunodominant antigens in different stages of Neospora caninum, Toxoplasma gondii, Sarcocystis spp. and Hammondia spp.

The family Sarcocystidae includes several intracellular coccidial parasites such as Toxoplasma gondii, Neospora caninum, Sarcocystis spp. and Hammondia spp. with heteroxenous life cycles involving different parasitic stages (oocysts/sporocysts, tachyzoites and bradyzoites in tissue cysts).

Genetic characterization of Toxoplasma gondii from human and chicken isolates from Argentina.

This study aimed to determine the nPCR-RFLP genotypes of newly obtained T. gondii isolates from human congenital toxoplasmosis cases in Argentina and to determine their allelic profiles for virulence genes ROP18/ROP5. In addition, the ROP18/ROP5 profiles were also determined for previously characterized T.

Morphological and molecular characterization of Sarcocystis spp. in pigs (Sus scrofa domestica) from Argentina.

Sarcocystis spp. are intracellular protozoan parasites with an obligatory heteroxenous life cycle. The objective of this study was to identify Sarcocystis spp.

Identification of Sarcocystis spp. in wild boars (Sus scrofa) from Argentina.

Sarcocystis spp. are intracellular protozoan parasites with an obligatory heteroxenous life cycle. The objective of this study is to identify Sarcocystis spp.
