Termite sensitivity to temperature affects global wood decay rates.

Deadwood is a large global carbon store with its store size partially determined by biotic decay. Microbial wood decay rates are known to respond to changing temperature and precipitation. Termites are also important decomposers in the tropics but are less well studied.

Characterization of polymorphisms and isoforms of the Clostridium perfringens phospholipase C gene (plc) reveals high genetic diversity.

Clostridium perfringens phospholipase C (Cp-PLC), also called alpha-toxin, is encoded by the plc gene and has been implicated in several diseases; however, only a few studies have described polymorphisms in this gene. The aim of this study was to analyze polymorphisms in the Cp-PLC nucleotide and amino acid sequences obtained from isolates from different regions and to compare them to Clostridium phospholipase C sequences deposited in the NCBI database. Environmental samples (sediment, poultry feed, sawdust) and stool samples (from poultry, bovine, swine, horse, caprine, bird, dog, rabbit, toucan) were collected from healthy and sick animals.
