Sentences with word «morphotype»

A study in a close relative, Burkholderia thailandensis (Bth), showed that a quorum sensing mutant had marked differences in colony morphology, but other genes involved in exopolysaccharide production could also be necessary for morphotype switching.

Here's one image from a field emission scanning electron microscope, showing what Hoover describes as features «interpreted as morphotypes of the cyanobacterium Calothrix spp.» (Journal of Cosmology):

Similar observations were noted at the Health Protection Agency (HPA) in the UK, where different morphotypes were observed from lung samples in mice infected with Bps K96243.

Several new morphotypes, e.g. circular, elongated, lobed, etc. have been catalogued by the researchers, each including individuals of different size.

Non-pyritized macrofossils showing two distinct morphotypes present on the same stratigraphic level, with part and counterpart.

Again, the leaf litter - dwelling P. boiei had the greatest number of antimicrobial morphotypes, presumably reflecting its exposure to soil bacteria species, many of which produce antibiotics.

In addition, the researchers detected antimicrobial activity in 27 bacterial morphotypes across the four frog species.

Seen here is a Late Cretaceous specimen from the Hell Creek Formation, morphotype HC62, taxon Rhamnus cleburni.

The larva uses the fungus as its food source, but as it feeds it causes the fungus to grow into several different forms, which the authors call morphotypes.

An additional 6 isolates with varying morphotypes retrieved from the UK HPA reference library will also be sequenced and compared for further identification of mutations that may lead to morphology differences.

It has been observed for nearly 80 years that Bps can change colony morphology, and recent studies have shown an association between morphotypes and specificity for body compartments, ability to adhere and penetrate epithelial cells or macrophages, and expression of virulence factors.

One of the two morphotypes is similar to those shown in figure 3.

The researchers found that for one frog (Proceratophrys boiei), microbe diversity was more than twice as high in continuous forest than in fragments (149 vs. 61 morphotypes, respectively), and its bacterial density varied between these forests.

With Bps K96243 these morphotypes were atypical of the morphologies seen to date.

To date, the molecular mechanisms underlying this morphotype switching remain unstudied.

MLST and PFGE analyses show that the morphotypes arise from a clonal population and that they are not the result of co-infections with different strains.

To understand the mechanisms that lead to morphotype switching, several different morphotypes of Bps will be sequenced and their genomes will be scanned for differences as part of the GSC contract.
