Microbial occurrence and antibiotic resistance in ready-to-go food items.

Foodborne pathogens, such as Escherichia coli, and Salmonella, are commonly prevalent in contaminated food products seen through annual food recalls. Excessive use of antibiotics through the past few decades has led to a multitude of antibiotic resistant bacteria, including foodborne pathogens. We investigated microbial occurrence and their antibiotics resistances in ready-to-go food items, i.e. canned food, bagged food, and baby food. A total of 112 isolates were isolated from varying food items, and 21 of these isolates were identified through 16S rRNA sequencing revealing Bacillus sp., Staphylococcus sp. and Micrococcus sp. Bagged food items showed the most microbial diversity as well as the largest colony forming unit (log 20-25 CFU/g). Isolates showed antibiotic resistance to ampicillin, streptomycin, chloramphenicol, and kanamycin at concentrations of 100, 500, and 1000 µg/mL. 57% isolates were ampicillin resistance followed by kanamycin (26%). A variety of microorganisms present in ready-to-go food items may not be pathogenic, however their occurrence and multiple antibiotic resistance (MAR) poses risk of transferring their genes to foodborne pathogens.

Interventions to increase uptake of the human papillomavirus vaccine in unvaccinated college students: A systematic literature review.

OBJECTIVE: The purpose of this systematic review is to summarize the best available evidence on interventions that could be implemented in the college environment to increase HPV vaccination uptake in college students who were not previously vaccinated. METHODS: Pubmed, CINAHL, PsycINFO, Cochrane, and EBSCO were searched in December 2017 to identify all literature meeting the following criteria: human subjects, English language, HPV, HPV vaccination, and college. PRISMA recommendations were followed. We focused only on manuscripts that reported vaccine uptake, excluding studies that only reported vaccine intentions. We identified 2989 articles; 101 relevant after screening; nine eligible for final qualitative review. RESULTS: Vaccine uptake rates ranged from 5% to 53%. Theory-based variables (e.g., perceived susceptibility and self-efficacy) were associated with vaccine uptake in most studies. A study exposing participants to a narrative video about HPV vaccination led by a combination of peers and medical experts produced the greatest difference in HPV vaccination initiation compared to a control group (21.8% vs 11.8%) of all the studies reviewed. CONCLUSIONS: Few interventions resulted in substantial HPV vaccine uptake. A combination of peer and provider encouragement may be the most effective method to increase vaccine uptake in this population.
