Helminthic parasites of invasive alien fish hosts in Marikina River system, Philippines: Revealing new parasite hosts and species records
No full textThe spread of invasive and endemic parasites in the Philippines, along with the co-introduction of invasive alien fish species (IAFS), could threaten the country’s local fauna, as well as pose socioeconomic and public health concerns. However, due to the scarcity of knowledge about fish parasites in the country, this incidence remains poorly understood. Thus, this study aims to explore the parasitic diversity of the common IAFS within the Marikina River system.https://digitalcommons.snc.edu/faculty_staff_works/1059/thumbnail.jp
Higher-Order Clicker Questions Engage Students and Prepare Them for Higher-Order Thinking Activities
No full textPrevious research has shown that the use of clickers in the classroom enhances student engagement. However, few studies have investigated how the type of clicker question may influence learning outcomes. To explore this, we compared the effects of lower-order cognitive skill (LOCS) and higher-order cognitive skill (HOCS) clicker questions on later exam performance in a biology course. During class time, students were presented with clicker questions directly related to unit content. Half of the content units were taught with LOCS, the other half with HOCS. To ensure that type of content did not influence results, the cognitive level of the clicker questions was counterbalanced across two semesters. The exams included a mix of LOCS and HOCS for each content unit. We also investigated the possible moderating effects of student perceptions on the relationship between type of clicker question and exam performance using student surveys. We found that using HOCS clicker questions significantly affects student learning. Practice with HOCS clicker questions improved performance on LOCS exam questions but not on HOCS exam questions. Students ranked lecture with clickers as a preferred and most helpful teaching methodology. Overall, these results suggest that practice with HOCS questions is engaging and gives students practice recalling content to “solve” a problem, thereby encoding low-level information and preparing them for higher-order thinking activities.https://digitalcommons.snc.edu/faculty_staff_works/1057/thumbnail.jp
Characterization of LPS as a virulence factor in Burkholderia cepacia during plant and human infection
Get PDFBurkholderia cepacia is a gram-negative bacterium first characterized as the causative agent of sour skin in onion crops. More recently, B. cepacia has become a clinical concern as an opportunistic pathogen that can colonize the upper respiratory tract of cystic fibrosis patients and increase mortality in these patients. Infection is exacerbated by the intrinsic resistance to antibiotics found in this genus of organisms. Additional virulence factors help the bacteria persist in the host during infection. However, few of these factors have been described. In this work, we characterized a putative virulence factor that was first identified through an onion infection forward-genetic screen. A mutation in the rfbB gene led to structural differences in the lipopolysaccharide composition, specifically in the O-antigen subunit. While this mutation does not affect normal growth in nutrient-rich media, we demonstrate that biofilm formation and adhesion to the 5637 human epithelial cell line are reduced, leading to diminished virulence. Further characterization of this mutant, among others, aims to better understand necessary virulence factors and the mechanisms required for pathogenicity in both plant and human hosts
