Coliform bacteria, fabrics, and the environment
No full textBackground People come into contact with coliform bacteria at recreational sites. Previous research on bacteria adhering to fabrics and surfaces focused on the viability of clinically significant microbes, but did not examine the quantity of bacteria. This study examined the viability and quantity of coliform bacteria adhered to common fabrics. Methods The fabrics of 100% cotton, blended cotton, and silk were exposed to a mixture of environmental coliform isolates. Fabrics were incubated in the dark at 25°C or 37°C or in direct sunlight at room temperature for 30, 60, 90, and 120 days. The quantity and viability of the bacteria were determined by the Most Probable Number technique using Colilert reagent (IDEXX Laboratories, Westbrook, ME) and eosin methylene blue agar, respectively. Results The highest numbers of bacteria were detected for each type of fabric when stored in the dark at 25°C, whereas the lowest numbers of bacteria were detected when fabrics were stored in the dark at 37°C. Low numbers of bacteria were detected on silk and blended cotton exposed to sunlight at room temperature, but not 100% cotton. Conclusion It appears that coliform bacteria can survive on fabrics longer than previous studies have reported. Coliform bacteria survive better in the dark, at lower temperatures, and on fabrics that can retain moisture. These findings can be applied directly to the viability of bacteria on clothing and potential human exposure to fecal pathogens
Social networking and support: No, I don’t know how to play golf (Chapter 4 from Black Faculty in the Academy Narratives for Negotiating Identity and Achieving Career Success)
No full textThrough candid discussions and personal counter-narrative stories, Black Faculty in the Academy explores the experiences and challenges faced by faculty of color in academe. Black faculty in predominantly White college and university settings must negotiate multiple and competing identities while struggling with issues of marginality, otherness, and invisible barriers. This important book illuminates how faculty can develop a professional identity that leads to success in academe, while at the same time remaining true to cultural and personal identities. Through rich narratives, chapter authors situate race-related encounters at the center of their experience in an effort to deconstruct and challenge commonly held assumptions about life in academe. They also provide key recommendations and strategies to help faculty of color ensure their continued professional success. Framed by critical race theory, these stories show how faculty can successfully maneuver through all stages of a career in academe, including tenure and promotion, publication, mentoring, networking, teaching, and dealing with institutional climate issues. This valuable book is for faculty and administrators seeking to create an environment that nurtures professional growth and fosters success among Black faculty.https://digitalcommons.lewisu.edu/psychology_fac-books/1024/thumbnail.jp
Basal NF-κB controls IL-7 responsiveness of quiescent naïve T cells
No full textT cells are essential for immune defenses against pathogens, such that viability of naïve T cells before antigen encounter is critical to preserve a polyclonal repertoire and prevent immunodeficiencies. The viability of naïve T cells before antigen recognition is ensured by IL-7, which drives expression of the prosurvival factor Bcl-2. Quiescent naïve T cells have low basal activity of the transcription factor NF-κB, which was assumed to have no functional consequences. In contrast to this postulate, our data show that basal nuclear NF-κB activity plays an important role in the transcription of IL-7 receptor α-subunit (CD127), enabling responsiveness of naïve T cells to the prosurvival effects of IL-7 and allowing T-cell persistence in vivo. Moreover, we show that this property of basal NF-κB activity is shared by mouse and human naïve T cells. Thus, NF-κB drives a distinct transcriptional program in T cells before antigen encounter by controlling susceptibility to IL-7. Our results reveal an evolutionarily conserved role of NF-κB in T cells before antigenic stimulation and identify a novel molecular pathway that controls T-cell homeostasis
