Introduction: Escherichia coli is a component of human physiological flora. Pathogenic E. coli strains are a significant etiologic factor for numerous infections, mainly the urinary system, digestive system, respiratory system as well as bacteraemia and post-operative infections. Purpose: To compare the genetic similarity of Escherichia coli strains, isolated from biological material collected for routine microbiological diagnostics. Materials and methods: The examination performed on the Escherichia coli strains, isolated from material collected from patients hospitalized in various clinics and delivered for routine laboratory diagnostics. The analysis was conducted using the ADRSSR method.Results: As a result of the analysis of genetic similarities of examined strains using the ADRSSR method, nine clones were distinguished, clones A and B considered being most numerous. Clone A was predominant in samples from internal diseases clinics while cloning B – from neonatological clinics. Conclusions: The results point to a significant role of monitoring of homogeneity of bacteria strains isolated in the range of the health care providers. It is directly connected with the safety of hospitalized patients as well as effectiveness and course of the treatment. The use of the ADSRRS method gives the opportunity of early detection of the moment of colonization in the monitored place

Abstract Background The recent outbreak of COVID-19 has impacted adversely upon the mental health of millions of people worldwide. Impacts on the mental health conditions and the associated predictors relating to adults in Pakistan, the fifth most populous country in the world, during the COVID-19 remain understudied. Our aim was to investigate distress, anxiety, and overall mental health and their associated predictors among Pakistani adults in this pandemic. We specifically examine mental health issues based on the distance from the epicenter, (a predictor that has revealed opposing evidence in other countries) based on the theories of typhoon eye effect and ripple effect. The sample consisted of 601 adults who were surveyed online about 2.5 months into the outbreak across Pakistan with varying distances from the epicenter of COVID-19 of Karachi. Results The results showed that 9.2 and 19.0% of the participants surpassed the cut-off criteria for distress and anxiety disorders, respectively. Overall, the distance from the epicenter positively predicted the mental health of adults in Pakistan, and family size negatively moderated this effect. The distance from the epicenter negatively predicted distress and anxiety disorders for adults in large families, which are quite common in Pakistan. Conclusion The evidence of the study interestingly finds that the prediction of the mental health of people by their distance from the epicenter depends on family size. The evidence of this study can help to provide initial indicators for mental health care providers to screen vulnerable groups in Pakistan, a populous country that continues struggling to cope with the COVID-19 pandemic.

Background Students returning to school who are breastfeeding face unique challenges. There is limited literature on breastfeeding university students. Several researchers have studied breastfeeding employees in the workplace. Institutions of higher education closely mimic the employment environment. Breastfeeding college students who express their milk while at school share similar challenges to employed mothers. A baccalaureate nursing program is rigorous and little is known about the challenges facing breastfeeding student nurses returning to classes. Research aim To explore the breastfeeding experience of baccalaureate nursing students. Methods Our study was a cross-sectional descriptive qualitative design. Purposive sampling was used to enroll participants ( N = 12). In depth, semi-structured interviews were conducted. Qualitative thematic analysis was used to analyze the data both manually and using Dedoose QDA software. Results An overarching theme of pervasive conflict between the role of the breastfeeding mother and the role of the student nurse surfaced. Three interrelated organizing themes also emerged; challenging, vulnerability, and resilience. Time constraints, self-care versus role demands, and structural accommodations contributed to the challenges. Only one participant indicated a knowledge of her breastfeeding rights. All of the participants expressed gratitude for faculty and community support, regardless of conflicts. Conclusion Breastfeeding participants were both vulnerable and resilient. Faculty may improve experiences through providing specific areas of support. A breastfeeding support policy outlining student rights and faculty responsibilities is needed to educate, guide, and enforce protections. Health care providers may enhance breastfeeding students’ experiences through anticipatory guidance, education, and continued support.

Policy Practice

Purpose There has been an increase in research exploring the area of intellectual and developmental disabilities (IDD) and diabetes. Despite being described as instrumental to diabetes care for people with IDD, the role and experiences of family carers, such as parents and siblings, are often neglected in this research. However, it is clear that family carers do not feel that they have sufficient knowledge about diabetes. The purpose of this commentary is to extend the content from “Diabetes and people with learning disabilities: Issues for policy, practice, and education (Maine et al., 2020)” and discuss how family carers can feel better supported when caring for someone with IDD and diabetes. Design/methodology/approach This commentary discusses specific efforts such as STOP diabetes, DESMOND-ID and OK-diabetes for people with IDD including family carers. Encouragement is given for health care providers to recommend such programmes to people with IDD and their family carers. It is also suggested that health care providers involve family carers in diabetes care planning and implementation for people with IDD. Findings It is hoped that if changes are made to current diabetes practices and more research with family carers is conducted, diabetes prevention and management for people with IDD will be more successful and family carers can feel more confident in providing support to their loved ones. Originality/value Research exploring the role of family carers in diabetes care for people with IDD and diabetes is very limited. This commentary makes recommendations to help family carers feel better supported in their role. It also provides areas for future research.

Helicases are nucleic acid-unwinding enzymes that are involved in the maintenance of genome integrity. Several parts of the amino acid sequences of helicases are very similar, and these quite well-conserved amino acid sequences are termed “helicase motifs”. Previous studies by X-ray crystallography and single-molecule measurements have suggested a common underlying mechanism for their function. These studies indicate the role of the helicase motifs in unwinding nucleic acids. In contrast, the sequence and length of the C-terminal amino acids of helicases are highly variable. In this paper, I review past and recent studies that proposed helicase mechanisms and studies that investigated the roles of the C-terminal amino acids on helicase and dimerization activities, primarily on the non-hexermeric Escherichia coli (E. coli) UvrD helicase. Then, I center on my recent study of single-molecule direct visualization of a UvrD mutant lacking the C-terminal 40 amino acids (UvrDΔ40C) used in studies proposing the monomer helicase model. The study demonstrated that multiple UvrDΔ40C molecules jointly participated in DNA unwinding, presumably by forming an oligomer. Thus, the single-molecule observation addressed how the C-terminal amino acids affect the number of helicases bound to DNA, oligomerization, and unwinding activity, which can be applied to other helicases.

Binding Glycoprotein

Lactoferrin (Lf) is a conserved iron-binding glycoprotein with antimicrobial activity, which is present in secretions that recover mucosal sites regarded as portals of invaded pathogens. Although numerous studies have focused on exogenous Lf, little is known about its expression of endogenous Lf upon bacterial infection. In this study, we investigated the distribution of Lf in mice intestine during Escherichia coli (E. coli) K88 infection. PCR and immunohistology staining showed that mRNA levels of Lf significantly increased in duodenum, ileum and colon, but extremely decreased in jejunum at 8 h and 24 h after infection. Meanwhile, endogenous Lf was mostly located in the lamina propria of intestine villi, while Lf receptor (LfR) was in the crypts. It suggested that endogenous Lf-LfR interaction might not be implicated in the antibacterial process. In addition, it was interesting to find that the infiltration of neutrophils into intestine tissues was changed similarly to Lf expression. It indicated that the variations of Lf expression were rather due to an equilibrium between the recruitment of neutrophils and degranulation of activated neutrophils. Thus, this new knowledge will pave the way to a more effective understanding of the role of Lf in intestinal mucosal immunity.

In the present paper we describe a new carboxylic acid transporter in Escherichia coli encoded by the gene yaaH. In contrast to what had been described for other YaaH family members, the E. coli transporter is highly specific for acetic acid (a monocarboxylate) and for succinic acid (a dicarboxylate), with affinity constants at pH 6.0 of 1.24±0.13 mM for acetic acid and 1.18±0.10 mM for succinic acid. In glucose-grown cells the ΔyaaH mutant is compromised for the uptake of both labelled acetic and succinic acids. YaaH, together with ActP, described previously as an acetate transporter, affect the use of acetic acid as sole carbon and energy source. Both genes have to be deleted simultaneously to abolish acetate transport. The uptake of acetate and succinate was restored when yaaH was expressed in trans in ΔyaaH ΔactP cells. We also demonstrate the critical role of YaaH amino acid residues Leu131 and Ala164 on the enhanced ability to transport lactate. Owing to its functional role in acetate and succinate uptake we propose its assignment as SatP: the Succinate–Acetate Transporter Protein.

Abstract Objectives The emergence of colistin-resistant Enterobacteriaceae from human and animal sources is one of the major public health concerns as colistin is the last-resort antibiotic for treating infections caused by multidrug-resistant Gram-negative bacteria. We aimed to determine the prevalence of the prototype widespread colistin resistance genes (mcr-1 and mcr-2) among commensal and pathogenic Escherichia coli strains isolated from food-producing and companion animals in Iran. Results A total of 607 E. coli isolates which were previously collected from different animal sources between 2008 and 2016 used to uncover the possible presence of plasmid-mediated colistin resistance genes (mcr-1 and mcr-2) by PCR. Overall, our results could not confirm the presence of any mcr-1 or mcr-2 positive E. coli among the studied isolates. It is concluded that despite the important role of food-producing animals in transferring the antibiotic resistance, they were not the main source for carriage of mcr-1 and mcr-2 in Iran until 2016. This study suggests that the other mcr variants (mcr-3 to mcr-9) might be responsible for conferring colistin resistance in animal isolates in Iran. The possible linkage between pig farming industry and high level of mcr carriage in some countries needs to be clarified in future prospective studies.

Escherichia coli has had a central place in water microbiology for decades as an indicator of faecal pollution. It is only relatively recently that the role of E. coli as pathogen, rather than indicator, in drinking water has begun to be stressed. Interest in the role of E. coli as a cause of diarrhoeal disease has increased because of the emergence of E. coli O157:H7 and other enterohaemorrhagic E. coli, due to the severity of the related disease. There are enterotoxigenic, enteropathogenic, enterohaemorrhagic, enteroinvasive, enteroaggregative and diffusely adherent strains of E. coli. Each type of E. coli causes diarrhoeal disease through different mechanisms and each causes a different clinical presentation. Several of the types cause diarrhoea by the elaboration of one or more toxins, others by some other form of direct damage to epithelial cells. This paper discusses each of these types in turn and also describes their epidemiology, with particular reference to whether they are waterborne or not.
