Ectoenzyme activities of alkaline phosphatase (APA) and leucine aminopeptidase (LAP) associated with Trichodesmium, a globally significant dinitrogen (N2) fixer, were measured on cruises to the Bermuda Atlantic Time-Series (BATS) site. Rates associated with Trichodesmium were compared to microbial enzyme activities in natural seawater between August 1992 and November 1997. Colonies of Trichodes...

Towards assessing the biodiversity and biogeography of Trichoderma, we have analyzed the occurrence of Trichoderma species in soil and litter from four areas in China: North (Hebei province), South-East (Zhejiang province), West (Himalayan, Tibet) and South-West (Yunnan province). One hundred and thirty five isolates were grouped according to tentative morphological identification. A representa...

Tritrichomonas foetus is a flagellate protozoan and the etiological agent of bovine genital trichomoniasis [1], which is an infectious venereal disease. This parasite is usually found associated with the mucosal surface of the urogenital tract in females or the male preputial and penile membranes. In females, the clinical manifestations may include abortion, with repetition of estrus at irregul...
