Detection of Toxoplasma gondii DNA by qPCR in the feces of a cat that recently ingested infected prey does not necessarily imply oocyst shedding

Detection of Toxoplasma gondii DNA in cat feces is considered indicative of the presence of T. gondii oocysts. This study aims to demonstrate that the high sensitivity of qPCR can lead to T. gondii DNA detection in cat feces in the absence of oocysts. A cat immune to toxoplasmosis was fed with a mouse experimentally infected with T. gondii. Detection of DNA of this parasite was performed by qPC...

Diversity does not Necessarily Imply Adaptability

Dynamic optimiser design currently assumes that diversity is a desirable property towards achieving adaptability, as a population-based optimiser contains an implicit memory. This paper examines the applicability of this assumption. Population-based algorithms of different size are tested against optimisers using a single solution. Results presented here suggest that this view is somewhat simpl...

The Toxoplasma Gondii Oocyst from Cat Feces

Coccidian oocysts resembling those of Isospora bigemina were excreted by cats fed Toxoplasma. In order to identify these oocysts with Toxoplasma infectivity a number of critical comparisons were made. The appearance of oocysts and Toxoplasma infectivity was simultaneous in the feces of 23 of 24 adult cats, 3-5 days after feeding of Toxoplasma cysts; in the feces of 4 out of 9 cats, 7-10 days af...
