The role and genetic control of non-coding RNAs in bacterial infection

Promoters are genetic elements that facilitate the transcription of a gene and they have been found in front of non-coding RNA (ncRNA) genes in different organ-isms, e.g. the model plant Arabidopsis thaliana. A similar element, DUSE, has been found in front of ncRNAs in the social amoeba Dictyostelium discoideum and a part of this project has been to analyze the function of this putative promoter element through cloning and expression studies. A construct to analyze the func-tion of DUSE was successfully designed and introduced into D. discoideum but full expression studies were not finished because of shortage of time.

Preoperativ hud- desinfektion

Introduction. Infection Prevention is one of the surgical nurses' main responsibilities. One of the steps which patients undergo in this purpose before surgery is the preoperative skin desinfektion. Background. The patient washes the day before surgery with Descutan cutaneous sponge 4 %, a sponge containing chlorhexidine.

Probiotika som prevention mot urogenitala sjukdomar

About 10 % of the adult women population in Sweden are treated annually for urinary tract infections. The increasing bacterial resistance towards antibiotics is classified by WHO (World Health Organization) and ECDC (European Centre for Disease Prevention and Control) as one of the greatest treats for human health in a global perspective. To find alternatives scientists are studying the possibility to use probiotics to reduce the frequency of recurring urinary tract infections. This literature study examines five randomized double blinded placebo controlled studies where different strains of Lactobacillus have been used as a prophylactic to women suffering from recurrent urinary tract infections and bacterial vaginosis. Overall the studies do not display enough promising results to recommend the use of probiotics as a prophylax or cure..

Development of new food products with components active against Helicobacter pylori - with purpose to improve gastric health in humans

Gastric and intestinal disorders are common and costly human health problems worldwide. Helicobacter pylori are a gram-negative, pathogen bacteria and the most common cause of duodenal and gastric ulcer in the stomach the intestinal mucosa. Prolonged infection and colonization can lead to chronic gastritis and stomach cancer. H. pylori are present in the gastric and intestinal mucosa of half of the world population and a relation between infection and low socioeconomic status has been shown.

Spolmaskangrepp är ett ökande problem hos värphöns

This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

Evaluation of a selective media for the detection of gram-positive bacteria in leg ulcers and pressure wounds

Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens.    The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.

Bärarskap av meticillinresistent Staphylococcus pseudintermedius (MRSP) hos svenska hundar :

During the last years, meticillin resistant Staphylococcus pseudintermedius (MRSP) have caused an increasing number of infections in Swedish dogs. MRSP is resistant against a majority of the antimicrobials available for dogs in Sweden, making it difficult to treat the infection. Our knowledge of the bacterium is limited, making it hard to handle infected dogs in a proper way. The aim of this study was to investigate for how long time dogs, who have an infection caused by MRSP, become carriers of the bacterium. Other factors like treatment with antimicrobials, the correlation between clinical symptoms and carriage, common diagnoses and institutionalization where also looked upon.

Faktorer som påverkar sjuksköterskans följsamhet till riktlinjer : En litteraturstudie

Cross infection is a global health problem. The cost for cross infection increases every year. Florence Nightingale focused her attention on preventing cross infections by using good hygiene and as a nurse that is one of your more important tasks. Nurses have guidelines for how hygiene should be implemented in practice. The aim of this study is to investigate factors that influence nurses´ compliance to guidelines regarding hygiene.

A literature study on Methicillin-resistant Staphylococcus pseudintermedius (MRSP) : classification, resistance mechanisms, risk factors and clonal distribution

The increased frequency of reported Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is of great concern to small animal healthcare due to limited options of antimicrobial therapy. The aim of this literature study is to investigate 1) characteristics and classification of S. pseudintermedius, 2) resistance mechanisms and emergence of MRSP, 3) risk factors for selection of MRSP, and 4) clonal distribution around the world. S. pseudintermedius is a skin and mucosal commensal in healthy dogs and cats, but can cause infections, including pyoderma. Beta-lactam antibiotics inhibit bacterial growth by binding to the penicillin binding protein (PBP), a vital enzyme in the synthesis of the bacterial cell wall.

Metodjämförelse mellan instrumenten Vitros 5,1 FS och QuikRead CRP för analysen P-CRP

In studies of serum, in the early 1930s, from patients with pneumonia, a factor was found. It could agglutinate certain pneumococcal species. This factor, which later became known as C-reactive protein (CRP), increased sharply during the early and middle stages of the disease. CRP was identified as an acute phase protein and found especially in Bacterial infections. CRP is synthesized in the liver by stimulation of interleukin 6 (IL-6), which is produced by the monocytes, and consists of five non-covalently bound subunits.The aim of this study was to compare two different analytical instruments (Vitros 5.1 FS Ortho-Clinical Diagnostics and QuikRead CRP Orion Diagnostica) for CRP analysis.

Identifiering av infektion i sår, en litteraturstudie

Regardless of what discipline nurses work in, wound care is one of the tasks. Caring for wounds involves early detection of signs of infection, in order to avoid complication. Wound infection extends suffering for the patient and causes unnecessary costs for society. The aim was to describe how nurses can identify infection in wounds. Method: The design of the study was a literature review, where13 scientific articles were examined and analyzed.

Borrelia burgdorferi : metodutveckling och tillämpning avseende odling och resistensstudier mot komplement, särskilt interaktion med faktor H

The genus Borrelia is a widespread, pathogenic pest and the causative of among others borreliosis or Lyme disease. The vector for the bacteria is the hard tick, Ixodes ricinus and the infection is transferred through a bite. Untreated, Borrelia may cause arthritis, heart damage or neuroborreliosis. Infection is made possible through different strategies for avoiding the body?s complement system.
