The Isolation and Characterization of Novel and Non- Lysogenic Bacteria from Soil and the Discovery of Broad-Host-Range Phages Infecting Multiple Genera.

To explore how microbial interactions within the rhizosphere influence the diversity and functional roles of bacterial communities, we isolated 21 bacterial strains from soil samples collected near Rocky Branch Creek on the University of South Carolina campus. Our findings revealed that a significant proportion of the isolated bacterial strains are lysogenic. Contrary to predictions of a narrow host range, most of the bacteriophages derived from these lysogenic bacteria demonstrated the ability to infect a broad range of bacterial strains.

Transition readiness and coping styles in adolescents with type 1 diabetes.

Purpose: Although promoting positive coping and reducing negative coping improves health, little research has examined how types of coping relate to transition readiness in adolescents with type 1 diabetes (T1D). This study aimed to clarify the direct and indirect relations between coping style and transition readiness. We first examined which coping styles predict transition readiness in adolescents with T1D and then explored whether diabetes distress mediates the relation between disengagement coping and transition readiness.

Immune and neural response to acute social stress in adolescent humans and rodents.

Studies in adults have linked stress-related activation of the immune system to the manifestation of psychiatric conditions. Using a translational design, this study aimed to examine the impact of social stress on immune activity in adolescents and on neuronal activity in a preclinical mouse model. Participants were 31 adolescents (ages 12-19), including 25 with mood and anxiety symptoms.

New Genera and Species of and Bacteriophages Provide Insights into Phage Genome Evolution.

Previous studies have identified diverse bacteriophages that infect strain CB15 ranging from small RNA phages to four genera of jumbo phages. In this study, we focus on 20 bacteriophages whose genomes range from 40 to 60 kb in length. Genome comparisons indicated that these diverse phages represent six phage genera and one additional genus that includes both and phages.
