Sentence examples for strains may be present from inspiring English sources

The existence of multiple strains of S. aureus in persons involved in this outbreak is not surprising, as 20%to40%0% of adults are estimated to be colonized at any time, and multiple strains may be present in the same person.

The observation that certain HIV strains may be present in a patient for a long time before they grow to a detectable viral load [ 39, 40] hints however towards a picture of a dynamical change in the environmental conditions in the host.

The observation that some viral strains may be present in a patient for a long time before they appear in detectable numbers favours the idea of a dynamical change in the environmental conditions in favour of X4 viruses [ 39, 40] at a higher level of abstraction.

Not least since our results indicate that it must be taken into account that oedema disease inducing strains also may be present in apparently healthy herds [ 1].

We examined the use of the Saga probe on some bacterial strains that may be present in the female genital tract [ 19, 20].

In addition to the low T cell epitope content and limited conservation with circulating influenza strains, tolerizing epitopes may be present in H7-HA, contributing to the low immunogenicity and poor efficacy of the HA-based vaccine.

E-Predict also has limited applicability to complex samples, in which several closely related strains of the same species may be present.

We also note that the β-lactamases may be present in strains belonging to phylogenetic groups from commensal groups A and B1, as well as virulent strains from group D. We note also that the majority of ESBL/AmpC-producing strains have one or more virulence genes tested.

Further genetic characterization of GBS-associated strains with HS∶41 and HS∶19 demonstrated that these serotypes represent clonal populations [18], [19], suggesting that specific virulence traits relevant to the onset of GBS may be present in strains with these serotypes.

Moreover, while there are known to be many strains of MDV-1, only one may be present within each barn at any one time, suggesting that without subsequent pathotyping experiments, it is difficult to understand the effect that MDV virulence has on MD outbreak dynamics within a barn.

As genes present in strains 409-05, 317 or both, but not in 594 may be present in the missing genome sequence of strain 594, those differences will not be discussed in text.
