Assays for fungal infection
First Claim
1. A method for detecting the presence or absence of any species of a fungus belonging to the genus Pneumocystis in a sample, comprisingi. obtaining a sample suspected of containing fungal nucleic acid from the genus Pneumocystis,ii. contacting said sample with a forward primer consisting of SEQ ID NO:
- 19 and a reverse primer consisting of SEQ ID NO;
20 in the presence of one or more internal PCR amplification controls under conditions under which PCR may occur; and
iii. detecting the presence or absence of an amplified identifying region of fungal nucleic acid in the sample,wherein said identifying region of fungal nucleic acid comprises SEQ ID NO;
18, the complement or transcript thereof, or a sequence having 80% or more sequence identity with SEQ ID NO;
18, the complement or transcript thereof, said identifying region being present in species of the genus Pneumocystis but not those of the genus of Candida or Aspergillus, andwherein the presence of said amplified identifying region of fungal nucleic acid in the sample indicates the presence of any species of a fungus belonging to the genus Pneumocystis in the sample, and the absence of said amplified identifying region of fungal nucleic acid in the sample indicates the absence of any species of a fungus belonging to the genus Pneumocystis in the sample.

Abstract
Methods and kits are described for testing for the presence or absence of any fungus in a sample. Examples of fungi that can be detected include, but are not limited to, those belonging to the genera Candida, Aspergillus and Pneumocystis. The methods include obtaining a sample suspected of containing fungal nucleic acid, including at least one universal region of fungal nucleic acid, and testing for the presence or absence in the sample of the at least one universal region of fungal nucleic acid. Samples may be biological or non-biological.
