Many studies have shown that soil bacteria, actinomycetes and fungi are the main source of soil enzymes (Magnuson and Crawford 1992) and that the biomass of these micro-organisms has a large effect on measured enzyme activity (Tabatabai and Dick 2002).
CARP's resolution in response to antibiotics and the isolation of two bacterial actinomycetes, Rhodococcus and Dietzia papillomatosis, from skin scrapings of CARP patients have led some to believe that its etiology is bacterial.
Thus, this study investigated whether the populations of naturally-occurring soil bacteria, fungi and actinomycetes influence the action of fungicides applied in various ways on the survival and growth of B.
In the experiments, applying BOF tended to increase bacterium, actinomycete and fungus populations, but SF application increased actinomycetes only, compared with those prior to the experiment (Table 7).
Due to their physiology and adaptation abilities, actinomycetes pose a particular threat to diverse materials.
1) The most common organisms involved in the development of this condition include the fungus Madurella mycetomatis and the Actinomycetes Nocardia Brasieliensis, Actinomadura madurae and Actinomadura pelletieri.
For the enumeration of viable total microorganisms, the serial dilution technique described in Wollum (1982) using the following culture media was used: nutrient agar for total bacteria, potato dextrose water (PDW) medium for total fungi and soil extract for actinomycetes.
isolates from local laboratories were identified at the species level via classical biochemical methods and minimum inhibitory concentration levels for Nocardia and Actinomycetes were reported for all antibiotics according to the Clinical and Laboratory Standards Institute guidelines ([3,5]).
But given the study on indigenous Actinomycetes by a team of researchers led by Irene Alcantara-Papa of the National Institute of Molecular Biology and Biotechnology (BIOTECH), University of the Philippines Los Baos, the country may eventually reduce importing antibiotics.
The aim of the present study was to screen actinomycetes of various ecological niches in Pakistan for cytotoxic and antitumor compounds.
Soil microflora such as bacteria, fungi and actinomycetes produce various secondary metabolites.
The second volume covers antimicrobial susceptibility testing, aerobic actinomycetes, mycobacteriology and antimycobacterial susceptibility testing, mycology and antifungal susceptibility testing, parasitology, and viruses and chlamydiae, while the third addresses procedures in immunology; molecular diagnostics; epidemiologic and infection control microbiology; quality assurance and control, laboratory records, and water quality; biohazards and safety; and bioterrorism.
