A low metastatic clone, G6, was isolated from the B16 melanoma cell line by cloning procedure. When the cells were cultured in vitro with fibroblasts from newborn mice, the lung-colonizing potential of G6 cells was substantially increased. The effect of coculture depended on the number of the fibroblasts. The elevated colonizing potential of G6 cells was reversed to the original low potential b...

Dark septate endophytic (DSE) fungi represent a frequent root-colonizing fungal group common in environments with strong abiotic stress, such as (semi)arid ecosystems. This work aimed to study the DSE fungi colonizing the plants of semiarid sandy grasslands with wood steppe patches on the Great Hungarian Plain. As we may assume that fungi colonizing both invasive and native species are generali...

Herbaceous plant species are important components of forest ecosystems, and their persistence in forests may be affected by invasive plant species that reduce mycorrhizal colonization of plant roots. I examined the effect of the invasive plant Alliaria petiolata on arbuscular mycorrhizal fungi (AMF) colonizing the roots of three forest plant species. AMF root colonization and community structur...

Serotype III group B streptococcus (GBS) causes more invasive disease in infants than do other serotypes in North America. We used multilocus sequence typing to identify clones within 28 invasive serotype III GBS isolates identified from a population-based study and 55 serotype III GBS colonizing isolates from a cohort of women from the same population. Ten allelic sequence types (STs) were ide...

Blue green algae was isolated from fresh water bodies of Allahabad region, Yamuna River, India to produce biodiesel. Based on rate of growth in cultural media and morphological characters and biomass production, 8 colonizing blue green algae isolates were selected for the further biofuel production work. To further narrow down the number of isolates, the carbonic anhydrase enzyme assay was used...

Urogenital infections are a worldwide shared problem that represent the most common reason for a woman to decide to visit to gynaecologist or urologist. The origin of the uropathogens in uncomplicated urinary tract infection and bacterial vaginosis is the fecal flora. Key element of pathogenesis namely the ability of the pathogens to survive exposure to the microflora that exists on the externa...

OBJECTIVES MRSA is a major antimicrobial resistance (AMR) pathogen. The reservoir of infecting isolates is colonization, which is the site of evolutionary selection. The aim was to identify if AMRs in colonizing MRSA populations diversified and potential mechanisms of resistance gene transfer in vivo. METHODS Nasal swabs from 38 MRSA carriers admitted to hospital were plated and 20 individual...
