Many youths who are victimized by peers suffer from depression symptoms. However, not all bullying victims show depression symptoms and individuals' biological sensitivity may play an important moderating role in this regard. In line with this notion, peer victimization has been associated with increased depressive symptoms in youth with higher basal cortisol secretion. It is unclear, however, whether this moderating effect of cortisol really concerns the environmental effect of peer victimization on depression...

This study describes the molecular characterization of an NDM-7 carbapenemase-producing Escherichia coli strain Ec188, recovered from a rectal swab of a male patient who had travelled to Pakistan before his hospitalization at the Hospital del Mar in Barcelona, Spain. The Ec188 isolate, assigned to a new multilocus sequence type ST679, was resistant to all beta-lactams, aminoglycosides (gentamicin, tobramycin, and with reduced susceptibility to amikacin), and ciprofloxacin. The blaNDM-7 gene was located on a 50 kb IncX4 plasmid (pEc188-NDM7), both in the original and transconjugant strains...

A foodborne illness outbreak involving an elite sports team was investigated by a public health unit in Sydney, Australia. An epidemiological association was established between gastrointestinal illness and the consumption of food supplied by an external caterer, with a lamb meal most strongly associated with illness. Genetically identical Salmonella isolates were identified from clinical specimens, residual food items, and an environmental swab taken from the catering premises. The training schedule and other club operations were significantly affected by this outbreak...

BACKGROUND AND OBJECTIVE: Animal models using rodents are frequently used for the purpose of practicing microvascular anastomosis - an essential technique in cerebrovascular surgery. However, safely and efficiently exposing rat's target vessels is technically difficult. Such difficulty may lead to excessive hemorrhage and shorten animal survival. This limits the ability to perform multiple anastomoses on a single animal and may increase the overall training time and costs. We report our model for microsurgical bypass training in rodents in two consecutive articles...

BACKGROUND: During functionality testing and packaging of reusable surgical instruments (RSI) for sterilisation, instruments are frequently touched. Considering the lack of standards relating to hand hygiene frequency and use of gloves in the sterilising service unit packing area, we aimed to determine the effect of hand hygiene and glove use on maintenance of RSI cleanliness. METHODS: Following manual and automated cleaning, Halsted-mosquito forceps were assessed for adenosine triphosphate (ATP), protein and microbial contamination after handling with gloved and ungloved but washed hands utilising an ATP surface swab test, bicinchoninic acid assay, and standard culture plate/broth, respectively...

Effects of bedding with recycled sand and season on lying behaviors, hygiene, and preferences of late-lactation Holstein cows were studied. It was hypothesized that recycled sand will decrease lying time and increase hygiene scores due to increased moisture content and organic matter, and thus a preference for the control sand will be evident. Cows (n = 64) were divided into 4 groups (n = 8 per group) per season. In summer (August to September), cows were balanced by days in milk (268.1 ± 11.9 d) and parity (2...

BACKGROUND: The importance of upper airway structure in the susceptibility of the lower respiratory tract to colonization with potential pathogens is well established. With the advent of rapid, high throughput, next generation sequencing, there is a growing appreciation of the importance of commensal microbial populations in maintaining mucosal health, and a realization that bacteria colonize anatomical locations that were previously considered to be sterile. While upper respiratory tract microbial populations have been described, there are currently no published studies describing the normal microbial populations of the bovine lower respiratory tract...

BACKGROUND: Cervical cancer, nearly all cases of which are caused by one of several high-risk strains of the human papillomavirus (hr-HPV), leads to significant morbidity and mortality in individuals with a cervix. Trans masculine (TM) individuals were born with female reproductive organs and identify as male, man, transgender man, or another diverse gender identity different from their female assigned sex at birth. Routine preventive sexual health screening of TM patients is recommended, including screening for cervical cancer and other sexually transmitted infections (STIs); however, as many as one in three TM patients are not up-to-date per recommended U...

Macrorhabdus ornithogaster is a yeast organism that infects multiple species of captive and wild birds. Diagnosis of infection in vivo has proven difficult historically, as shedding can be intermittent, and not all positive animals are clinically ill. We compared polymerase chain reaction (PCR) of cloacal swab samples and fecal Gram's stain (FGS) for diagnosis of active shedding of M ornithogaster in a captive flock of budgerigars ( Melopsittacus undulatus ). Of the 100 birds sampled, 57 (57%) were positive for M ornithogaster by PCR and 24 (24%) were positive for M ornithogaster by FGS...

Shiga toxin (Stx)-producing Escherichia coli (STEC) infections are implicated in the development of the life-threatening hemolytic-uremic syndrome (HUS). Despite the magnitude of the social and economic problems caused by HUS, no licensed vaccine or effective therapy is currently available for human use. Prevention of STEC infections continues being the most important measure to reduce HUS incidence. This is especially true for Argentina where HUS incidence among children is extremely high and shows an endemic pattern...

BACKGROUND: Personal social networks have a profound impact on our health, yet collecting personal network data for use in health communication, behavior change, or translation and dissemination interventions has proved challenging. Recent advances in social network data collection software have reduced the burden of network studies on researchers and respondents alike, yet little testing has occurred to discover whether these methods are: (1) acceptable to a variety of target populations, including those who may have limited experience with technology or limited literacy; and (2) practical in the field, specifically in areas that are geographically and technologically disconnected, such as rural Appalachian Kentucky...

A set of real-time PCR methods for the detection of C. estertheticum, C. gasigenes and C. ruminantium, the causative agents of blown pack spoilage (BPS) in vacuum packaged beef, was developed. Robust validation of the sensitivity and specificity was carried out in the three matrices (beef meat drip, wet environmental swabs and dry environmental swabs) as encountered in our testing laboratory and against Clostridium strains (n=76) and non-Clostridium strains (n=36). It was possible to detect 4-5 spores per ml for C...

Bats occupying hibernacula during summer are exposed to Pseudogymnoascus destructans (Pd), the causative agent of white-nose syndrome (WNS), and may contribute to its dispersal. Furthermore, equipment and clothing exposed to cave environments are a potential source for human-assisted spread of Pd. To explore dispersal hazards for Pd during the nonhibernal season, we tested samples that were collected from bats, the environment, and equipment at hibernacula in the eastern US between 18 July-22 August 2012. Study sites included six hibernacula known to harbor bats with Pd with varying winter-count impacts from WNS and two hibernacula (control sites) without prior history of WNS...
