For study of the role of lipopolysaccharide (LPS) character in colonization of the mouse large intestine, use was made of S. typhimurium strain SL5316, which is streptomycin resistant and smooth (wild-type LPS) but nonvirulent because it is Aro- (aromatic dependent). Several rough variants of different LPS chemotype derived from strain SL5316 comprised: an rfb deletion transductant making type ...
One common form of reticulate evolution arises as a consequence of secondary contact between previously allopatric populations. Using extensive coalescent simulations, we describe the conditions for, and extent of, the introgression of genetic material into the genome of a colonizing population from an endemic population. The simulated coalescent histories are sampled from models that describe ...
Before milk was incorporated into the Zionist project as a nutritional supplement for children, dairy celebrated agricultural produce. Milk had ability to bring together varied group of technical experts, who hailed in School program national triumph. Situating its local well international contexts, this article shows how imagined and presented way that tied food, public health, Jewish physique...
Root and lower stem insects cause significant damage to conifers, vector phytopathogenic fungi, and can predispose trees to bark beetle attacks. The development of effective sampling techniques is an important component in managing these cryptic insects. We tested the effects of trap type and stereochemistry of alpha-pinene, in combination with ethanol, on catches of the root colonizing weevils...
critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...
BACKGROUND Group B Streptococcus (GBS) remains susceptible to penicillin, however, resistance to second-line antimicrobials, clindamycin and erythromycin, has increased since 1996. We describe the age-specific antibiotic susceptibility profile and capsular type distribution among invasive and colonizing GBS strains. METHODS We tested 486 invasive GBS isolates from individuals of all ages coll...
