Bacillus cytotoxicus-A potentially virulent food-associated microbe.

Bacillus cytotoxicus is a member of the Bacillus cereus group with the ability to grow at high temperatures (up to 52℃) and to synthesize cytotoxin K-1, a diarrhoeagenic cytotoxin, which appears to be unique to this species and more cytotoxic than the cytotoxin K-2 produced by other members of this group. Only a few isolates of this species have been characterized with regard to their cytotoxic effects, and the role of cytotoxin K-1 as a causative agent of food poisoning remains largely unclear. Bacillus cytotoxicus was initially isolated from a food-borne outbreak, which led to three deaths, and the organism has since been linked to other outbreaks all involving plant-based food matrices. Other studies, as well as food-borne incidents reported to the UK Food Standards Agency, detected B. cytotoxicus in insect-related products and in dried food products. With insect-related food becoming increasingly popular, the association with this pathogen is concerning, requiring further investigation and evidence to protect public health. This review summarizes the current knowledge around B. cytotoxicus and highlights gaps in the literature from a food safety perspective.

Factors that assist and hinder efforts towards recovery from eating disorders: A comparison of collegiate female athletes and non-athletes.

This study compared female intercollegiate athletes' and non-athletes' experiences of working towards recovery from an eating disorder. Participants (55 athletes, 99 non-athletes) responded to open-ended questions about factors that influenced their progress towards recovery. Both subgroups reported that Supportive Relationships and Cognitive/Emotional Shifts were most helpful. The third most frequent helpful factor for athletes was Sport Performance Concerns, for non-athletes it was Treatment. Athletes' most frequent hindering factors were Negative Emotions/Cognitions, Sport Pressures, and Hurtful Modelling, while non-athletes reported Negative Emotions/Cognitions, Lack of Support, and Hurtful Modelling. Sport-specific factors were among the most common themes in athletes' responses; therefore, athletes' recovery experiences and treatment needs appear unique.
