Probes to Microbial Water Quality Monitoring (2008)

Dual-labeled Hydrolysis, Inge V. Foulds, Rebecca A. Guy, Anita Kapoor, Chongxie Xiao, Ulrich J. Krull, ...

Issues of water quality are a global problem with potentially devastating results in communities if microbial levels are not monitored and controlled effectively.This is especially true with the...

Localization of the Mating Type Gene in Agaricus bisporus

Xu, Jianping, Kerrigan, Richard W., Horgen, Paul A., Anderson, James B.

The cultivated mushroom Agaricus bisporus is secondarily homothallic. Most basidia produce two basidiospores, each of which receives two of the four postmeiotic nuclei. Usually, the two packaged...

Investigation of Mitochondrial Transmission in Selected Matings between Homokaryons from Commercial and Wild-Collected Isolates of Agaricus bisporus (= Agaricus brunnescens)

Jin, Tianru, Sonnenberg, Anton S. M., Horgen, Paul A.

Ten heterokaryons of Agaricus bisporus (= Agaricus brunnescens) were shown to carry four different mitochondrial (mt) genotypes by analysis of mt restriction fragment length polymorphisms (RFLPs)....

Real-Time PCR for Quantification of Giardia and Cryptosporidium in Environmental Water Samples and Sewage

Guy, Rebecca A., Payment, Pierre, Krull, Ulrich J., Horgen, Paul A.

The protozoan pathogens Giardia lamblia and Cryptosporidium parvum are major causes of waterborne enteric disease throughout the world. Improved detection methods that are very sensitive and rapid...

Inheritance of Strain Instability (Sectoring) in the Commercial Button Mushroom, Agaricus bisporus

Li, Aimin, Begin, Marc, Kokurewicz, Karl, Bowden, Christine, Horgen, Paul A.

The button mushroom, Agaricus bisporus, is a commercially important cultivated filamentous fungus. During the last decade, the button mushroom industry has depended mainly on two strains (or...

Uniparental Mitochondrial Transmission in the Cultivated Button Mushroom, Agaricus bisporus

Jin, Tianru, Horgen, Paul A.

A uniparental mitochondrial (mt) transmission pattern has been previously observed in laboratory matings of the cultivated mushroom Agaricus bisporus on petri dishes. In this study, four sets of...

Crosses among Homokaryons from Commercial and Wild-Collected Strains of the Mushroom Agaricus brunnescens (= A. bisporus)

Castle, Alan J., Horgen, Paul A., Anderson, James B.

A new technique for the production of hybrid strains of the cultivated mushroom Agaricus brunnescens is described. Homokaryons were recovered from regenerated protoplasts obtained from several...

Restriction Fragment Length Polymorphisms in the Mushrooms Agaricus brunnescens and Agaricus bitorquis

Castle, Alan J., Horgen, Paul A., Anderson, James B.

Two Agaricus species, A. brunnescens (a commercial mushroom) and A. bitorquis (a wild, edible species), were examined for restriction fragment length polymorphisms. EcoRI-digested nuclear DNA from...

In Vitro Ribonucleic Acid Synthesis in the Zoospores of the Aquatic Fungus Blastocladiella emersonii

Horgen, Paul A.

The zoospores of Blastocladiella emersonii posses three ribonucleic acid polymerases. No general or specific inhibitor for the enzymes were found in the protoplasm of the spores.

Specific Inhibitors of the Three RNA Polymerases from the Aquatic Fungus Blastocladiella emersonii

Horgen, Paul A., Griffin, David H.

Specific inhibitors of each of the three RNA polymerases of Blastocladiella emersonii have been found. Cycloheximide specifically inhibited the in vitro activity of the DEAE-fraction I enzyme,...

Cytochrome Oxidase Activity in Blastocladiella emersonii1

Horgen, Paul A., Griffin, David H.

Studies of cytochrome oxidase in isolated mitochondria of Blastocladiella emersonii Cant. and Hyatt show that the enzyme was present in zoospores and throughout the development of ordinary colorless...

Real-Time PCR Assay for Detection and Genotype Differentiation of Giardia lamblia in Stool Specimens

Guy, Rebecca A., Xiao, Chongxie, Horgen, Paul A.

Real-time PCR, using dual-labeled fluorescent probes targeting the β-giardin gene, was used to detect Giardia lamblia in human stool specimens and to discriminate between isolates from the two major...
