BACKGROUND the arginine catabolic mobile element (ACME) associated with staphylococcal cassette chromosome mec (SCCmec) in the USA300 clone of community-acquired methicillin-resistant Staphylococcus aureus enhances its fitness and ability to colonize the host. Staphylococcus epidermidis may act as a reservoir of ACME for S. aureus. We assessed the diffusion of ACME in methicillin-resistant S. e...

High soil phosphorus (P) concentration is frequently shown to reduce root colonization by arbuscular mycorrhizal (AM) fungi, but the influence of P on the diversity of colonizing AM fungi is uncertain. We used terminal restriction fragment length polymorphism (T-RFLP) of 18S rDNA and cloning to assess diversity of AM fungi colonizing maize (Zea mays), soybean (Glycene max) and field violet (Vio...

Arbuscular mycorrhizal (AM) fungi are biotrophic symbionts colonizing about two-thirds of land plant species and found in all ecosystems. They are of major importance in plant nutrient supply and their diversity is suggested to be an important determinant of plant community composition. The diversity of the AM fungal community composition in the roots of two plant species (Agrostis capillaris a...

The prophylactic use of fluconazole is common in blood and marrow transplant (BMT) recipients. To evaluate how fluconazole has influenced the development of azole resistance and candidemia, weekly mouthwashings were done, and fluconazole susceptibility was determined for 1475 colonizing and invasive isolates obtained from patients undergoing BMT. Of 585 patients, 256 (44%) were colonized with C...

The analyses of the insect species found on decomposing remains may provide useful information for the estimation of the minimum time elapsed since death and other parameters, such as causes and circumstances of death. The majority of research has focused on the early colonizing species, typically blowflies, while research concerning late colonizing insects is currently sparse. Dermestid beetle...

Helicobacter (H.) heilmannii sensu stricto (s.s.) is a zoonotic bacterium that naturally colonizes the stomach of dogs and cats. In humans, this microorganism has been associated with gastritis, peptic ulcer disease and mucosa associated lymphoid tissue (MALT) lymphoma. Little information is available about the pathogenesis of H. heilmannii s.s. infections in humans and it is unknown whether di...

1 The attractiveness of pitfall traps baited with a synthetic host volatile attractant to colonizing adult Colorado potato beetle, Leptinotarsa decemlineata (Say) was evaluated in a field setting. 2 Significantly more postdiapause, colonizing adult L. decemlineata were captured in baited than unbaited pitfall traps. 3 The potential for this synthetic kairomone to enhance the efficacy of trap cr...

leaf-colonizing strain of Bacillus cereus. and Bacillus thuringiensis and in a subsp. kurstaki expressed in Escherichia coli the NRD-12 isolate of Bacillus thuringiensis Insecticidal activity of the CryIIA protein from

DNA fingerprinting with the moderately repetitive sequence Ca3 has repeatedly identified groups of genetically similar strains of Candida albicans that are more frequently isolated than other groups of strains from human hosts in a geographical locale. Members of these groups are found in approximately 30% of healthy individuals and in up to 70% of patients suffering from candidiasis. The high ...
