actinomycosis/phosphatase

Thermoactinomycetes vulgaris is a thermophilic actinomycetes growing optimally at 50 degrees C and Streptomyces albus, S. coelicolor, S. fasciculus and S. olivochromogenes are thermophilically disposed transition species of actinomycetes, which have optimum biomass at 40 degrees C. The acid/alkaline

A fatal case of hepatic actinomycosis with portal vein thrombosis is reported. The diagnosis of actinomycosis was delayed because of its rarity in Taiwan. This 63-year-old man was admitted due to body weight loss and poor appetite. No fever was noted before admission. Liver biochemical test showed a

A case of liver actinomycosis successfully treated with high doses of penicillin for a long period after surgery is reported. The unusual location of the disease and early detection difficulties delayed the diagnosis and establishment of proper treatment, causing additional liver damage. Serum

The screening of microbial natural products continues to represent an important route to the discovery of novel chemicals for development of new therapeutic agents. The aim of this work was to develop an efficient method for the detection of immunosuppressive compounds produced by soil

Cervicofacial actinomycosis is a unique polymicrobic infection of endogenous origin, displaying a highly variable clinical course, ranging from an acute, suppurative lesion to a chronic fibrotic process more suggestive of a malignancy. Lesions advance with total disregard for tissue planes,

OBJECTIVE To identify novel microbial inhibitors of protein phosphatase 1 (PP1). RESULTS 750 actinomycetes and 408 microfungi were isolated from Sabah forest soils and screened for production of potential PP1 inhibitors using an in vivo screening system, in which candidate inhibitors were identified

Shrimp farming constitutes an important source of revenue and employment in many developing countries. However, the shrimp industry has always been plagued with infectious diseases having varied aetiologies. Dominated by non - specific immune mechanism, preventive health care strategy is the most

The reactions between seven fluorogenic substrates and different groups of enzymes, esterases, lipases, phosphatases, and dehydrogenases, were studied in a search for a new method for the detection of actinomycete spores. Fluorescence measurement was chosen as a fast and sensitive method for

A patient with hepatic actinomycosis caused by Actinomyces odontolyticus is presented. The clinical course was characterized by 2 yr of episodic abdominal pains and fever together with marked acute elevations of serum alkaline phosphatase. The diagnosis escaped extensive laboratory studies, 2 liver

Lactacystin (1.3 microM), a metabolite from an actinomycete, induced the formation of bipolar projections at both sides of the cell body of Neuro 2a cells 1 day after treatment and networks at and after 3 days and enhanced acetylcholinesterase activity (a marker of neuronal differentiation). Thus,

Qualitative and quantitative nature of phosphatases produced by various fungal, bacterial, and actinomycetes isolates from diverse soils was examined. Soil fungi, particularly those belonging to the genera Aspergillus and Penicillium, were found to be most effective in producing phosphatases intra-

Sediment samples were collected from different stations of the Vellar estuary for isolation of total actinomycetes and phosphate solubilizing actinomycetes. Phosphatase activity in the sediments was also investigated Consistently a higher number of actinomycetes, phosphate solubilizing actinomycetes
