Detection and genotypes of Toxoplasma gondii DNA in feces of domestic cats in Colombia.

The high prevalence of Toxoplasma gondii in the human population in Colombia has been linked to the existence of a high density of urban stray cats, exposing the whole population to a high density of oocysts. The goal of this study was to determine the DNA prevalence of T. gondii by conventional PCR and to phylogenetically analyze ROP18 sequences from positive samples in domestic cat (Felis catus) fecal samples in the city of Armenia, Quindío.

Coinfections and differential diagnosis in immunocompetent patients with uveitis of infectious origin.

Background: Making a definite diagnosis of infectious uveitis is a challenging task because many other infectious, and non-infectious uveitis, may have similar non-specific symptoms and overlapping clinical appearances. Co-infections in immunocompetent patients are not frequently proved with traditional serologic-diagnostic tools.

Methods: Descriptive transversal study, in a Uveitis Service of an Ophthalmology Reference Center, in Bogotá, Colombia, from July 2014 to February 2016.

Polymerase chain reaction (PCR) in ocular and ganglionar toxoplasmosis and the effect of therapeutics for prevention of ocular involvement in South American setting.

Introduction: Cases of toxoplasmosis present in South America tend to be more severe than that found in other continents. Here, we present our clinical experience of ocular and ganglionar toxoplasmosis in the use of PCR, and of the treatment to prevent ocular involvement.

Methodology: Retrospective analysis of clinical charts of patients with ocular and lymphadenitic toxoplasmosis at the parasitology and tropical medicine consultation in the "Universidad del Quindio" in Colombia.
