Abstract
A new method to detect the protozoan Neospora caninum using indirect in situ polymerase chain reaction (PCR) is described. In situ PCR combines the advantages of the extraordinarily high sensitivity and specificity of PCR and the in situ representation of immunohistochemical methods. We describe an indirect in situ PCR, whereby the amplified products were detected using a primed in situ (PRINS) reaction with hapten-labeled nucleotides and visualized using fluorochrome-labeled antibodies. This technique was carried out in both infected cell cultures and formalin fixed, paraffin embedded tissues. Clear signals were obtained in the N. caninum positive samples using in situ PCR, whereas control slides with Toxoplasma gondii infected tissues always yielded negative results.
